Dear Reader,

Welcome to the June issue of Power in Motion, providing you with an update on thenewest products and showing you innovative solutions and applications from all areasof Power Transmission and Motion Control.

According to the latest data from IMS Research, the worldwide market for low voltageAC & DC motor drives is experiencing a greater decline than previously expected as aresult of the economic downturn, with the revised forecast predicting a contraction of5.6% in terms of revenues over 2008 levels. Latest data obtained for the last quarter of2008 and the first quarter of 2009 indicate a decline in the motor drives market acrossall regions. But it should be noted that many suppliers of motor drives have indicated aslight increase in orders in the second quarter of 2009, and forecasts for 2010 to 2012remain positive. According to IMS Research analyst Jenalea Howell, “government legislation and stimulus packages will provide opportunities for suppliers to the lowvoltage motor drives market, which is expected to come through the recession with asmall contraction and resume positive growth in 2010.”

We are looking forward to see you at the important events for our industry in autumn,like the Motek show in Stuttgart, where the organizers have announced unprecedentedhigh numbers of exhibitors which have already booked their place on the trade showgrounds.

Luxury cruise liner ‘Celebrity Solstice’, whichwas put to sea for her maiden voyage at theend of 2008, uses drive technology that incor-porates sophisticated bearing technology.

The ship’s propulsion and steering drivesutilise one FAG radial spherical roller bearingand two FAG spherical thrust roller bearings,which enable the liner to accelerate to aspeed of 24 knots (45km/h). The bearingsensure that steering and precise decelera-tion manouvres are performed smoothlyand safely. Special coatings on the bearingsare critical to the efficient operation of thedrives.

Worth almost half a billion euros, CelebritySolstice is the largest ship ever constructedin Germany. The vessel measures 315m inlength – the length of three football pitches.The ship accommodates around 2,900 pas-sengers in 1,430 cabins and features an arrayof amenities, including a huge theatre, acasino and a real lawn for playing golf.

Propulsion and steering of the ship are com-bined in a freely rotating vertical pod out-side of the hull. These so-called ‘POD drives’provide extremely low vibration and noiselevels during operation, therefore enhanc-ing passenger comfort. The drives signifi-cantly improve the maneuverability, andtherefore the safety, of the ship, as well as of-fering higher efficiencies, resulting in bothlower fuel consumption and reduced emis-sion levels. The power output per drive unitis 20MW.

The bearings support the drive shaft on the lo-cating bearing side in each of the two enginepods, accommodating thrust forces and loadsfrom the engine and propeller. The largespherical thrust roller bearing, which has anoutside diameter of 850mm, serves as themain thrust bearing and is subjected to thrustloads of up to 150 tonnes at maximum speedsof 135rpm. Under extreme conditions, thebearing can even support loads of up to 430tonnes for short periods.

The smaller counter bearing, which is also anFAG spherical thrust roller bearing, has anoutside diameter of 620mm. The bearingwithstands reverse thrust loads during ma-neuvering operations. The bearing is de-signed for loads of up to 20 tonnes, althoughin extreme cases, it can withstand loads of upto 200 tonnes for short periods.

The radial spherical roller bearing is de-signed to accommodate radial loads fromthe engine, the weight of the propeller anddynamic forces. The bearings in the thrustblock unit are arranged in such a way thatthey align via a common point and so areable to compensate for any misalignment ofthe drive shaft.

The bearings play a pivotal role in improvingthe efficiency of the drive. In order to opti-mise bearing system kinematics and reducefriction, the outer ring of the radial sphericalroller bearing and the housing washers ofthe spherical thrust roller bearings are coat-ed with Durotect Z.

This special coating reduces the coefficientof friction and adhesion properties, while in-creasing the bearing’s resistance to corrosionand fretting. In addition, the outer diameterof the 7.5 tonne thrust block unit (flange con-nection) is equipped with a 14mm thick, syn-thetic compound coating, which offers ex-cellent damping properties, as well as pro-viding electrical insulation. This coating pre-vents the rolling contact zone from beingdamaged by leakage currents or downdraft.The coating provides reliable protection upto 15,000V.

The thrust block unit’s bearing and oil bath aremonitored using temperature sensors. The in-dividual bearings are also fitted with a condi-tion monitoring system that detects damageat an early stage, enabling maintenance tasksto be planned well in advance. This eliminatescostly, unexpected bearing failures.

Energy-efficient movement processes

Flexibility, lightness in relation to the mass to bedisplaced and energy efficiency are acquiring in-creasing significance in automation. With highlydiverse examples, nature demonstrates howmaximum performance can be achieved withminimum consumption of energy.

Dr. Eberhard Veit, Chairman of the ManagementBoard and Director of Technology and MarketPositioning at Festo AG, explains: “We are usingbionics to sound out new technologies and tooffer our customers even more efficient solutionsin automation.”

Over the past few years, the Festo Bionic Learn-ing Network – a cooperation of Festo withrenowned universities, institutes and develop-ment companies – has become established asan integral part of Festo’s innovation processes.

The Bionic Learning Network thus reflects Festo’ssolutions competence for evaluating new ap-proaches in sustainable product development.“We intend to be the innovation leader in our

sector. To this end, we must repeatedly traveldown new, in other words entirely different,paths in order to provide our customers withadded value,”says Dr. Veit.

Bionic design principles serve as the basis for thedevelopment of new gripper technology forflexible adaptive gripping in the mechanical han-dling industry.

In biomechatronics, Festo is investigating newapproaches in the control and regulation of au-tonomous bionic systems, all the way up tosmart system integration and the application ofstate-of-the-art communication technologies.Autonomous, versatile, adaptive and self-regulat-ing processes will acquire increasing significancein the future for the automation of production. Inthis process, the ongoing development of sen-sor and regulating technologies along the roadto decentralised, autonomous, self-controllingand self-organising systems is benefiting from in-spiration provided by nature.

AquaPenguin - an autonomous underwater vehicle The bionic penguins readily demonstrate what ismeant by learning from nature. The use of inno-vative technical materials and the creative com-bination of various design and functional princi-ples pave the way for new design opportunitiesand automation technology.

The AquaPenguins are designed as autonomousunderwater vehicles (AUVs) that independently

PIM_08_09.qxp 29-05-2009 12:38 Page 2

orient themselves and navigate through the wa-ter basin and develop differentiated, variable be-haviour patterns in group operation.

The penguins’hydrodynamic body contours andelegant wing propulsion principle were adoptedfrom their natural archetypes. The robotic pen-guins can manoeuvre in cramped spatial condi-tions, turn on the spot when necessary and – un-like their biological archetypes – even swimbackwards.

An entirely new feature in robotics is the torsothat can move in any direction. To make such an“organic” change of shape possible, the head,neck and tail segments were based on a new 3DFin Ray structure. This structure, derived from thetail fin of a fish, has thus been extended intothree-dimensional space for the first time. The ac-tuators and control electronics are housed in thedry main segment of the torso.

The manoeuvres are supported by an intelligent3D sensor system. To analyse their surroundings,the penguins are fitted with special 3D sonarwhich makes use of broadband ultrasound sig-nals, similar to those used by dolphins and bats.

The penguins’ torso design can be used in au-tomation as flexible tripods, thereby opening upnew fields of application in handling technology.The flexible tripod has an operating range thattranscends that of the conventional tripod con-figuration; for example, pick-and-place applica-tions with an offset of 90 degrees are possible.

In combination with a flexible and adaptive grip-per, fragile objects of various shapes can bemoved.

Intelligent sensors are also opening up new ap-plications. Thanks to its rapid, precise control, the

AquaPenguin can swim collision-free in groupoperation, with depth control, pressure and tem-perature compensation, and positional stability.Analogous transfer to automation technology isalso to be found in Festo’s regulation technolo-gy: for example in the new VPPM and VPWP pro-portional pressure regulation valves for actuatorpneumatics.

AirPenguin - self-regulating systems with collective behaviourThe AirPenguin is an autonomously flying objectwith collective behaviour that comes close to itsnatural archetype in terms of agility and ma-noeuvrability.

The AirPenguins are artificial penguins createdby the engineers from Festo, who have taughtthem “autonomous flight in the sea of air”. Agroup of three autonomously flying penguinshovers freely through a defined air space that ismonitored by invisible ultrasound “transmittingstations”. The penguins can move freely withinthis space; a microcontroller gives them free willin order to explore it.

If the 3D Fin Ray structure of the head and tailsections is transferred to the requirements of au-tomation technology, it can be used for instancein a flexible tripod with a very large scope of op-eration in comparison with conventional tripods.Fitted with electric drive mechanisms, the Bion-icTripod from Festo for example makes for pre-cise, rapid movements, just like the AirPenguin.

The transfer to automation technology is also tobe found by analogy in regulating technologyfrom Festo, for example in the new VPPM and VP-WP proportional pressure-regulating valves foractuator pneumatics.

A 360 tonne wooden bridge

was positioned over the

A7 national road near

Akkerwinde in Sneek

(the Netherlands). Prior to

being transported to its

destination, the whole

construction was lifted

using a hydraulic

computer-controlled

Synchronous Lift System.


Case Study

Synchronous Lift Systemputs up unique wooden bridge

The “Rijksweg 7 Sneek” project was commis-sioned by the Province of Friesland, Rijkswa-terstaat Noord Nederland (Ministry of Wa-terways and Public Works for the northernNetherlands) and the Municipality of Sneek.The project consists of building two wood-en bridges over the new southern A7 ringroad. Both bridges form “landmarks” orrecognisable features of the town. As part ofthe first phase, a new bridge was placed inthe Akkerwinde location at the end of No-vember 2008. The second bridge is plannedfor the Molenkrite area.

The new bridge consists of a steel deck andtwo vertical, wooden arches that are 32 me-tres long and 16 metres high. Bolts and legsjoin the arches together. The bridge was de-signed by OAK architecten - a collaborationbetween the engineering company Inge-

nieursbureau Oranjewoud in Heerenveen,Achterbosch Architectuur in Leeuwardenand Onix in Groningen. The wooden arch-

es were built by contrac-tor Schaffitzel from

Schwäbisch Hall inGermany. Wagen-

borg Nedlift fromGroningen was

respons ib lefor assem-

bly, lifting, transport and positioning. Thebridges are an example of progressive ar-chitecture, of which the term “durability” isan important element, alongside aestheticand structural criteria. This applies to boththe materials used and the lifespan.

What makes the bridge unique is thewooden arches and its use. Whilst there arealready a few modern wooden bridges inthe world, none of them until now havebeen built to such a scale and to support alltraffic. The wooden construction is able tosupport the steel deck and traffic from thehighest traffic class (60 tonnes) can driveover it. The bridge is 32 metres long 12 me-tres wide and 16 metres high. Total weightof the wooden superstructure and steelsubstructure adds up 360.000 kilo whiledrive bolts and link-up bars weigh 9000 ki-lo. 690 cubic metres of wood are used inthe construction.

Laminated cribbing blocks made of Accoyawood measuring 1080x1400 mm wereused for the arches. This type of woodcomes from production forests in NewZealand and is produced and supplied bythe Dutch company Titan Wood. Followingthe process of acetylation, the wood natu-rally absorbs less moisture, therefore in-creasing its durability. The German manu-facturer Schaffitzel guarantees a lifespan of80 years for this wood, as long as it is prop-erly maintained.

The new bridge's deck and arches weremounted on an assembly site around one

PIM_10_11.qxp 29-05-2009 12:44 Page 2

and a half kilometres away from thebridge's current location over the A7. Afterassembly, the bridge was lifted to the cor-rect height for its final position, using Ener-pac’s computer-controlled hydraulic Syn-chronous Lift System, which WagenborgNedlift invested in some time ago.

Project leader Michel de Jong of Wagen-borg Nedlift is extremely pleased with theoperation's progress and with the lift sys-tem in particular. “The system works per-fectly. We have already used it a number oftimes, but what was unique about this proj-ect was that we had to lift the bottom ofthe bridge up to 5.10 metres, whereas thelift system’s highest prop was 4.40 metres.”

The Enerpac Synchronous Lift System is acombination of digital control, switchingand monitoring. Thanks to specific software,lifting (and lowering) is extremely accurate;the lift system can lift even the heaviestloads with a controlled accuracy of 1mm.

Only four abutments with BLS Stage-Liftdouble-acting cylinders (one under eachcorner of the bridge) were needed to lift upthe special massive bridge. The BLS cylin-ders are intended for the “Lift and Crib” sys-tem and have integrated supports to makeit easier to position underlying paddingmaterials.

The four lift cylinders, with a total capacityof 1000 tonnes, were placed on hardwoodouter cribbing blocks, which were stackeddiagonally layer for layer. A new layer of out-

er cribbing blocks was put down afteraround each 10cm of lifting. In this way, thebridge was lifted around 50 centimetres perhour and in the end, the whole construc-tion rested on four "cribbing block towers",each approx. four metres high.

Each cylinder was connected to its own hy-draulic pump unit, which was controlled bycomputer using sensors placed right next tothe lift cylinders. The computer program con-trolled the cylinder movements, independ-ently of the measurements, by switching thehydraulic directional control valves. Duringthis control, short impulses are sent to thevalves in fractions of a second, so that individ-ual cylinder movements are kept muchsmaller than is possible using manual control.

Not only does the Wagenborg Nedlift sys-tem save a considerable amount of timecompared to manual lifting, but it also hasa very essential advantage: thanks to thesynchronous and therefore perfectly bal-anced lifting, virtually no internal stressesarise within the load. Michel de Jong: “Wechose Enerpac because it is a company thatoperates internationally, but more impor-tantly because of the accuracy of its system.The Synchronous Lift System allows us toperfectly manage and monitor the wholeoperation. And the data saved can be con-sidered afterwards, together with the cus-tomer, to evaluate how things went. Andwith this project, everything went as wewanted it to.”

A horizontal trim actuator

by Liebherr-Aerospace

Lindenberg GmbH, Germany,

is responsible for the

Fly-by-Wire Flight Control

System of a new regional jet.

A custom designed ballscrew

forms an essential component


Case Study

Stainless steel ballscrew takes aeroplane to the sky

The Sukhoi SuperJet 100, produced by Russ-ian aerospace firm Sukhoi Civil Aircraft Com-pany, is a modern, fly-by-wire regional jet inthe 75- to 95-seat category. It is still undergo-ing flight tests and the first commercial deliv-eries are expected later this year. This new re-gional jet will be officially launched at theParis Air Show in June.

An aeroplane must be in balance longitudi-nally in order to fly. This means that the neteffect of all the forces acting on the aero-plane produces no overall pitching momentabout the centre of gravity. Without a hori-zontal stabilizer there would be only onecombination of speed and centre of gravityposition where this requirement was met.The horizontal stabilizer provides a balancingforce to maintain equilibrium for differentspeeds and centre of gravity positions. Theballscrew is part of an actuator that movesthe horizontal tail surface of the plane up anddown to accommodate the changing centreof gravity.

"Breaking into the aerospace componentmarket has been a natural progression fromthe new product development standpoint,"says Alex Beck, international sales managerand co-owner of Steinmeyer. "We makeballscrews in all sizes from miniature to largeballscrews suitable for high load applications.

This design and engineering expertise, wewere sure, was going to make it possible todesign ballscrews for aerospace applications.

"Precision is key in ballscrew manufacturing.This particular ballscrew was going to be partof a flight critical application and there is noroom for error." Steinmeyer has traditionallymade all tools and prototypes in-house, anexperience which was going to prove veryuseful.

The ability to withstand stress is an importantfactor in the design of flight critical compo-nents. All structural parts need to be testedunder maximum stress levels. For that pur-pose design engineers at Steinmeyer simu-lated different load scenarios. An example isthe ‘runaway’check. During a ‘runaway’a mal-function of an electronic or electrical partcauses the actuator to run against its endstop at full speed and full motor torque. An-other scenario could be a gear box jammingleaving all parts locked under inertia. Thecomponents of the actuator have to with-stand these load conditions without causingthe actuator to fail. Should for whatever rea-son the actuator sustain damage duringflight, or should wear to the mechanical partsexcess certain limits, a sensor triggers analarm. The part can then be identified and re-placed during an inspection, rather than op-

PIM_12_13.qxp 29-05-2009 14:31 Page 2

erating the aircraft with the help of the back-up system for any length of time.

All parts of the horizontal stabilizer trim actu-ator were modelled in 3 D using SolidWorkssoftware. Various load conditions for all struc-tural parts were analysed with Finite ElementMethod (FEM) stress analysis and the designadjusted accordingly where necessary, espe-cially where safety was concerned. Everytime the design was changed, tests were car-ried out under a range of load conditions. Theballscrew in the actuator has a special fail-safe feature causing an alarm to be triggeredif the load limit is exceeded only once. Thedesign was only finalised when the achievedsafety margin was satisfactory.

The ballscrew is designed to operate 60,000flight cycles safely and accurately. It is madefrom Cronidur30 steel, a stainless steel specif-ically developed for aerospace applications.To make the component fit for the flight crit-ical application special care had to be takenduring the manufacturing process which in-volves the grinding of the steel parts and canlead to grinder burn with dangerous conse-quences.

Grinder burn is caused by excessive heatgeneration during the grinding of hardenedsteel parts. This induces tensile stresses into

the material which can lead to micro cracksand subsequent failure of the part. Althoughsometimes a blackened surface is an obvioussign of grinder burn being present, more of-ten than not there is no visible sign.

Conventional tests for the detection ofgrinder burn destroy the part. Steinmeyer, incooperation with Liebherr-Aerospace Lin-denberg GmbH, has developed a non-de-structive method to detect grinder burn us-ing the Barkhausen[1] effect. It involves send-ing an alternating magnetic field through thepart. Changes in the magnetic noise indicatestress conditions in the material. In order tointerpret the results correctly, each new partand the slightest design change require acompletely new calibration of the sensor.This is a complicated and time consumingprocess, but once calibrated the Barkhausennoise inspection allows complete, reliableand quick scanning of each ballscrew.

[1]The Barkhausen effect is a name given to the noisein the magnetic output of a ferromagnet when the magnetizing force applied to it is changed. Discovered by the German physicist HeinrichBarkhausen in 1919, it is caused by rapid changes ofsize of magnetic domains (similarly magnetically oriented atoms in ferromagnetic materials).

Modra Technology,

a specialist manufacturer of

carpet sample machines, has

chosen to base the motion

control system for its

innovative Mtuft range

of machines on

Powerlink technology


Application Story

Industrial Ethernet for multi-axis motion control

By using the deterministic Powerlink industrialEthernet networking technology for real-timemulti-axis synchronization, Mtuft machines seta new industry standard for speed, accuracyand flexibility. They can produce a new tuftedcarpet sample in just 20 minutes, including set-up time - a task which takes at least a day onconventional carpet sample machines or onproduction machines.

Modra Technology is a world leader in the de-sign, manufacture and supply of carpet samplemachines. Founded in 1991, the company ini-tially produced error-detecting sensors for in-creasing the efficiency of Axminster looms.During the course of this work it identified theneed for product development machines forcarpet designers and manufacturers. At thattime, carpet samples were either produced byhand - a very slow process - or by using vol-ume production machines, which was expen-sive and disruptive.

Modra Technology's first machine, known asthe Kibby, was designed to produce high qual-ity samples of Axminster and woven carpets,and is a worldwide success; to date, the com-pany has sold over 150 units in 24 countries.The latest, fourth-generation versions of thesemachines can accommodate very high needleinsertion rates of 5 per second- and are capa-ble of producing a complete 500 x 500mm

sample of Axminster carpet in just over 1 hour.When it came to developing a machine to pro-duce samples of tufted carpet, Modra Technol-ogy initiated the Mtuft project and set itselfsome ambitious design goals. Prime amongthese was the need to come up with a designthat would be flexible enough to simulate aswide a range of carpet production machines aspossible, in order that the samples would pro-vide an accurate representation of the finishedcarpets produced by various manufacturers'machines. To this end, the company chose touse an all-servo design, with a sophisticatedcontrol system based on Ethernet Powerlinkbased products.

According to Tim Modra, Managing Director ofModra Technology, "Complex high speed mul-ti-axis applications such as this traditionally in-volve a huge amount of wiring - mainly on thecontrol side, and especially for encoder feed-back. Obviously, over the years we have beenkeeping an eye on trends in decentralized mo-tion control and various strategies to help re-duce the amount of machine wiring, but wehad dismissed non-deterministic Ethernet asbeing unsuitable for critical real-time automa-tion control purposes. So when Baldorlaunched its Ethernet-based motion controllerand servos, which are designed specifically toovercome the real-time data transmission lim-itations of standard Ethernet but still use stan-

PIM_14_15.qxp 29-05-2009 14:05 Page 2

dard Ethernet cable between the controllerand the drives, we were keen to try them out."

By managing message exchanges in a preciseand defined sequence to ensure that only onenode communicates at any one time, Power-link adds determinism to Ethernet communi-cations - the protocol guarantees that all time-critical data is transferred within configurable,isochronous bus cycles. This prevents the typeof data collisions associated with standard Eth-ernet and dispenses with the need for bus ar-bitration schemes, thereby reducing datatransmission time overheads significantly.

The Mtuft carpet sample machine uses a com-bination of pneumatic and electrical actuationtechnology. There are nine axes of electrically-operated movement, all controlled by aNextMove e100 real-time motion controller.Seven axes are driven by MicroFlex e100 sin-gle-phase AC servo drives and BSM servomo-tors, using Ethernet Powerlink for all commu-nication between the between the controllerand the drives, and five of these axes use inter-polation - again, handled entirely over Power-link. The remaining two electrically-driven axesuse small DC motors.

Mtuft machines are freestanding units de-signed for autonomous operation, thoughtheir Ethernet architecture lends itself to facto-ry-wide integration and remote, internet-based diagnostics. The built-in host computeris an industry-standard PC, running the ma-chine control software and NedGraphics'

VisionTuft soft-ware for creatingnew carpet sample de-signs. Each carpet sample de-sign is exported by the Vision Tuftsoftware in OpenTuft format, and down-loaded via Ethernet to the NextMovee100 controller line by line.

The machine holds the web - the backing ma-terial for the carpet sample - in tension on twobacking drums driven in ratio gear mode. Tworeciprocating heads, positioned above and be-low the web, traverse the width of the materi-al. The needle motor provides the referencesignal for all interpolated axes, and the tophead employs a large servo for needle actua-tion, using a driven-spline arrangement to saveweight on the head itself. Each head is drivenin synchronism, and they can also be movedin a way to simulate production of carpet sam-ples with needle shift 'zigzag' patterns.

Tim Modra points out that the use of high-speed interpolation on the two main headdrive servos provides a key advantage overconventional mechanical systems. "We effec-tively have a software calibrator which enablesus to put a variable offset into the system. Soinstead of using precision mechanical gearsand cams - which are expensive, time-con-suming to configure and inherently inflexible -we can now calibrate our machines digitally,which is easily done using Baldor's Mint pro-gramming language. This all-electronic ap-proach has enabled us to create a physicallycompact machine with a small footprint, and

helps to reduce machine build time and costsignificantly. It also provides us with a highlyadaptable platform for future product devel-opment. The ability to purchase all the electri-cal drive products that we require - includingthe servo motors, controllers, cables and filters- direct from Baldor means that we have a veryefficient supply chain, which further helpsshorten our time to market."

Modra Technology's Mtuft machines look set toachieve for tufted carpet samples what the Kib-by has done for Axminsters. A single machinecan produce 1 metre or 2 metre wide samplesof cut/loop and cut/multi pile loop carpets ofany length in single or multiple colours, as wellas samples of servo loop scroll carpets, with ser-vo control of the pile height and up to eightcolours. The machine can accommodate yarngauges from 1.5 to 6.3 mm and uses a singleneedle per colour, which means that only onecone of each colour yarn is required. Conven-tional sample machines can require up to 200cones. This ease of set-up, combined with avery high stitching speed of up to 30 per sec-ond, enables a typical new carpet sample to beproduced in just 20 minutes.

The second generation of

the Segway Personal

Transporter uses a compact

and robust angular position

sensor to measure the

rider’s body angle which is

used as a reference to

generate the lateral

acceleration required.


Case Study

Potentiometer ensures safecornering of Personal Transporter

From its first introduction in 2001, the dis-tinctive two wheeled Segway PersonalTransporter has taken the world by storm.The PT removes the strain from workers andleisure users that would otherwise need totravel long distances on foot and it’s nowseen everywhere from airports to golf links.

The second generation PT is a futuristic self-balancing transportation device with highlysophisticated motion and stabilisation tech-nology that uses the rider’s natural bodymovements to propel and steer the vehicle.With highly efficient operation the vehicle canhit 12.5 mph and covers a range of 24 miles.

The Segway PT uses its LeanSteer steeringsystem to allow the riders body movementto guide the vehicle whilst the Segway SmartMotion (SSM) controller uses the same infor-mation to maintain motion and directionwith complete dynamic stability through itsbalance sensor assembly (BSA) which has in-tegral solid state rate gyro and tilt sensors.

In operation, the rider simply moves for-wards, backwards and to each side to pro-pel and steer the PT in the correspondingdirection whilst the highly developed con-trol system ensures that bumps, camber oruneven slopes which may affect the ridersbody position are fully compensated to en-sure completely smooth operation.

Clearly, to guarantee the safe operation ofthe PT and maintain its total reliability, longlife and competitive costs, the choice ofcomponents are of paramount importance.The LeanSteer system uses the compactand robust SP2880 angular position sensor.

The SP2800 is located at the pivoting base ofthe handlebar shaft, providing high-bandwidthangular position feedback that effectivelymeasures the rider’s body angle which is usedas a reference to generate the lateral accelera-tion required to balance the PT and its rider.

For this application, the conductive plastictechnology SP2880 sensor is a fully redun-dant design for maximum reliability featur-ing two completely independent measuringsystems, each with precious metal wipersand dual voltage outputs. The sensor pro-vides a 140 degree electrical range with aresolution of less than 0.01 degrees, linearityto +/- 0.3% and repeatability ≤ 0.03 degrees.

The 28mm diameter sensor is just 17mmlong, built from high quality temperature re-sistant plastic and features a push-on shaftcoupling and slotted flange mounting for fastinstallation. The highly durable housing is IP65rated for dust and water spray protection andhas an operating temperature range of -40 to150ºC, allowing its use in extreme weatherconditions. The rated life is over 50 million cy-cles and with a current consumption of lessthan 1mA, the SP2880 sensor more than sat-isfies the requirements for minimal energyuse on the battery powered Segway PT.

The 2880 series is a part of a wide range ofcontacting and non-contacting angular po-sition sensors available from Novotechnikthat are stocked and fully supported in theUK and Ireland by Variohm EuroSensor. Thisapplication illustrates Novotechnik’s capa-bility to provide standard products with cus-tomisation to adapt to the exact demandsof the customer’s application.

The MV-CS (Medium Voltage Control System) is a combination of tech-nologies and voltage levels. The most prominent feature of this switchgearis the strict division into two components. The basic unit contains the sys-tem cabinet, the energy distribution components and the cable connec-tion compartment. All components are passive units and therefore sub-ject to a minimal risk of failure. The single sections are insulated from eachother and the connection to the busbar possesses an integrated shuttermechanism. An intelligent decompression channel guarantees a safe re-lease of gases in the case of an internal arc. The slide-in withdraw unit in-cludes all electric relevant components for each possible option. Therefore99.99% of all failures within the system are appearing in the slide-in.

The system is standardized and has twointegrated busbar systems, thus systemredundancy is possible without any addi-tional components. Low voltage compo-nents are integrated in the withdraw unitand are automatically separated with itfrom the basic unit. All customer cablesare fitted into the terminal block locatedin the basic unit framework. Every with-draw unit has a touch screen which offers

operator convenience. Starting from parameter settings across the real val-ue display all the way up to the supportive error analysis, the ease of usecovers all requirements.

When the system is inserted, the locking bolts of the basic unit interlockwith the door’s framework on all sides. After complete locking of the frontdoor, the system complies with the IEC internal arc test requirements. Forall incurring works the withdraw unit can be completely removed makingit accessible from all sides. Furthermore the withdraw unit can be rolled,allowing for maintenance to be done at a comfortable place, like the work-shop. Single withdraw systems can be interchanged, while the other sys-tem components continue to work at their usual level. When highest sys-tem availability is required, the complete withdraw unit can be replacedwithin minutes.

Case Study

An 800 kW drive is making

the 70,000 tonne liquid

natural gas transport ship

LNG Abuja much easier

to manoeuvre, particularly

in ports. The drive is used

in conjunction with the

vessel’s bow thrusters.

The bow thrusters greatly enhance the ma-noeuvrability of the huge vessel but they hadone especially inconvenient shortcomingbefore the modifications were carried out bymarine power plant expert Wartsila Automa-tion of Montrose, Scotland. It was not possi-ble to start the 800kW motors used to pow-er the thrusters unless the ship’s main gener-ators were operating, which meant the ves-sels turbines had to be running.

The bow thrusters represent a very largeelectrical and mechanical load to the vessel’spower network and are remote from themain switchboard of the vessel. Over theyears, starting the huge thrusters representsa significant mechanical load to the genera-tors and turbines, which increases wear tobearings and mechanical components, aswell as producing a very significant voltagedrop on the network.

On investigating this problem, engineersfrom Wartsila discovered that the ship hadauxiliary generators with sufficient output topower the bow thruster drive motors whilethey were running, but that these generatorscould not supply the much larger currentneeded to start the motors.

At that time, the motors were equipped withconventional electromechanical star-deltastarters that had an initial inrush of around300% of the motor’s running current, andwhich also generated another large currentpeak during the star to delta transition. TheWartsila engineers knew that a variablespeed drive would allow much more con-trolled starting, with an inrush current limit-ed to little more than the normal runningcurrent of the motors.

After carrying out a careful technical evalua-tion, they found that Vacon offered an attrac-tive combination of price and performancefor the 800kW that was needed for this appli-cation. Further, the drive offered a synchroni-sation facility that would make it easy to by-pass when the bow thruster motors reachedfull speed.

The LNG Abuja has two bow thruster motorsmounted on a common shaft. The variablespeed drive is used to provide controlled ac-celeration for one of these, in such a way thatthe maximum current demand never ex-ceeds 110% of the motor’s normal runningcurrent – well within the capacity of theship’s auxiliary generators.

When the motor reaches full speed, as con-firmed by the synchronisation facility built in-to the drive, a contactor closes to bypass thedrive and connect the motor directly to thesupply. This arrangement means that no spe-cial provision has to be made for cooling thedrive, as it is only ever in use for short peri-ods.

With the bow thruster system running underthe power of one motor, the second motorcan then also be switched directly onto thesupply. Since this motor, mounted on a com-mon shaft with the first, is already rotating atclose to full speed, this switching operationproduces only a minor current peak.

“The versatility and performance of the Va-con drives allowed us to offer a very conven-ient and cost effective solution for the oper-ators of the LNG Abuja,” said Ian Gordon ofWartsila. “The results are excellent. The bowthrusters can now be used whenever theyare needed, and even started at short noticefor maintenance operations, without havingto worry about whether the main turbinesare running. That’s a big benefit for the ship’soperators, and it has been delivered at a verymodest cost.”

The modular bearing system for planetary gearsin wind turbine gearboxes

offers a standardisation ofthe bearings, a reduced

diversity of parts and simplified logistics.

Most wind turbines use gearboxes to trans-form the relatively low rotational speed ofthe main shaft into higher speeds requiredfor power generation. Because the forces amodern wind turbine gearbox has to trans-mit are forever increasing while the gearboxitself has to remain compact, single- or two-stage planetary gearboxes are commonly

used. The bearings of the planetary gears areamong the highest-loaded in this specific ap-plication. In modern gearboxes an integratedplanetary bearing arrangement is used, inwhich cylindrical roller bearings without anouter ring are fitted in the planetary gears,with the bore of the gear forming the outerraceway.

The modular concept is based on single-rowcylindrical roller bearings, without an outerring. They are equipped with a one-piece sol-id brass cage, which is guided by the innerring (MPB). This cage features inspectiongrooves for endoscopic inspection of the in-ner raceways as standard. Used consistentlythroughout the gearbox assembly, the mod-ular concept has numerous advantages for

the user: the designs of planetary bearingscan be simplified; the bearing design can bestandardised for the first and second gearstage and across various gearbox sizes; therequired number of bearing variants is re-duced; the modular design simplifies theadaptation of bearing set characteristics tothe requirements of each gear stage; theone-piece solid brass cage provides excellentrolling element guidance even during rapidacceleration; and the lubrication groovesprovided as standard improve the lubricationof the planetary gear bearings. The system isalready in use in the 1.5MW, 2MW and 2.5MWwind turbine gearboxes of a well-known Ger-man gearbox manufacturer.

When the process control

of the pumping station at

Parksluizen in Rotterdam,

the Netherlands, was

automated, a variable

speed drive for 690 V with

12 pulse power supply was

included in the installation.

In the Netherlands, regulating the water lev-el in streams, lakes, ditches, moats and canalsis critical for most activities. A level that is toolow will cause large ships to run aground,and one that is too high will make the verti-cal clearance under bridges insufficient. TheHoogheemraadschap van Delfland, or theDelfland Water Board, is one of 27 water au-thorities responsible for maintaining dikesand dams and controlling water level andwater quality. The Delfland region is one of

the most densely populated and highly in-dustrialized areas of the Netherlands withabout 1.4 million people and 40,000 busi-nesses in an area of 41,000 hectares

The harbour authorities of Rotterdam man-age the Parksluizen locks in Rotterdam, whichabout 22,000 ships pass through every year.They were completed in 1933 and consist oftwo locks connecting the shipping routefrom Delfshavense Schie canal to the NieuweMaas river, and the Coolhaven and Parkhavenports. The pumping station at Parksluizen wasbuilt in 1965. Delfland Water Board needed toautomate the process control and increasethe pumping capacity. They turned toBosman Watermanagement and Emotron tohandle the engineering, dimensioning andcommissioning of the pump and drive line.

Delfland Water Board wanted an upgrade ofthe existing installation with a diesel drivenpump. Replacing it with an automatic elec-tric drive solution would offer more efficientpump control with minimized energy con-sumption and improved user-friendliness. A690 V installation would also allow the use ofcheaper cabling and a more compact vari-able speed drive thanks to the lower current.The new solution is based on a BosmanBeveron 210 pump driven by a Siemens elec-tric motor with an output of 1,375 kW.

An Emotron FDU variable speed drive isused for the control. An IP54 classified en-

closure meant the variable speed drivecould be installed next to the pump. The 12-pulse variable speed drive in combinationwith a special star/delta transformer pro-vides a low THDI (Total Harmonic Distortionof Current). The pump shaft rotates at amaximum of 135 rpm due to the gearingdown from 1,000 to 135 rpm. The pump ro-tor and wear ring are made from durableand non-corrosive materials. The existingdiesel motor has been retained for emer-gency situations.

“We chose Emotron for the engineering ofthe drive system and the result is an effi-cient solution for our customer,” says Arwinde Klerk, Project Manager at Bosman Water-management.

The Delfland Water Board now benefitsfrom double the pumping capacity, 20 m?/sinstead of 10 m?/s. They have also improvedthe efficiency and reliability of the electricalpower and reduced stress on power distri-bution equipment thanks to lower harmon-ic distortions on the mains power.

“We also appreciated having a single com-pany responsible for the complete drive sys-tem. Emotron has supplied pump controlequipment for our pumping stations andwastewater treatment plants for many yearsnow,”says Piet van Mullem, Electro-TechnicalEngineer at Delfland Water Board.

Look beyond the pollution caused bywaste to consider its potential contri-bution to a more sustainable use ofnatural resources and raw materials

Since the 1970s, the Commission has intro-duced legislation to improve the treatment,management and limitation of waste. In2005, however, a ‘Thematic Strategy onWaste Prevention and Recycling' was pro-posed in order to improve efficiency and setup a holistic review of existing EU waste pol-icy. The new approach focuses on preven-tion and recycling. The Thematic Strategy al-so takes account of the whole lifecycle ofproducts. It proposes to look beyond thepollution caused by waste to consider itspotential contribution to a more sustainableuse of natural resources and raw materials.

Member states will be required to developwaste prevention policies that will "reachout to the individuals and businesses" re-sponsible for waste generated in the firstplace. EU-wide environmental standards onrecycling will also be adopted to "supportthe development of an EU market for sec-ondary (recycled) materials".

A key element of the new approach is thesimplification of legislation, and because itdoes not impose specific waste recycling orprevention targets, the Commission says it is"not expected to result in any quantifiablefinancial costs" on member states and busi-nesses. A revision of the Integrated Pollutionand Prevention Control Directive will betabled that will set "an ambitious bench-mark" to improve energy recovery from mu-nicipal incinerators. The Commission saysthe new energy efficiency benchmark "willdetermine whether an incinerator can beidentified as a recovery facility instead of adisposal facility".

These measures apply to all disposed sub-stances or objects, except gaseous effluents,

radioactive waste, mineral waste, animalcarcases and agricultural waste, wastewater,and decommissioned explosives. Thesetypes of waste are subject to specific EU leg-islation (see guidelines published by theCommission).

EU Member States must prohibit the aban-donment, dumping or uncontrolled dispos-al of waste, and must promote waste pre-vention, recycling and processing for re-use.

The EU’s strategy encourages co-opera-tion between the Member States with aview to establishing an integrated andadequate network of disposal installa-tions (taking account of the best availabletechnologies). The aim is for the EU as awhole to become self-sufficient in wastedisposal and the Member States to movetowards that aim individually. This net-work should enable waste to be disposedof in one of the nearest appropriate instal-lations, so as to guarantee a high level ofenvironmental protection.

The European Parliament agreed to a com-promise on recycling targets. The directiverequires governments to recycle 70% ofconstruction waste by 2020. If EU countriesdo not meet the targets by 2020, the Com-mission would take them to court for non-compliance. The compromise also created amore comprehensive waste hierarchy: pre-vention, re-use, recycling and recovery withenvironmental disposal as a last option. Thefinal compromise gives incineration a betterposition in the waste hierarchy.

The EU’s waste policy underlines the ‘pol-luter pays principle’, and will consequentlyhave an impact on EPTDA members --though the degree to which companies willbe affected will vary considerably accordingto the type of waste and the country inwhich it is produced and disposed of. TheEU’s strategy also emphasises preventionand recycling. While no fixed targets for pre-vention have been agreed at an EU level,policies drawn up by individual MemberStates could impose an added financial bur-den on businesses.

Meeting with Europe’s PT/MCkey decision makers in Rome!EPTDA Annual Convention 2009: Excellence in Relationships

The European Power Transmission Distribu-tors’ Association (EPTDA) is hosting its 2009Annual Convention build around the theme“Excellence in Relationships”, at the Mar-riott Park Hotel, Rome from 23-25 Septem-ber 2009. EPTDA is the leading body in global Power Transmission & Motion Control(PT-MC) industry and takes great pride inmany valuable benefits it offers to its mem-bers and partners. One of these many bene-fits is the Annual Convention, a unique net-working platform that brings the key playersand decision makers together on one stage todefine strategies and future course of the PT-MC industry.

EPTDA brings you an exclusive scoop of a re-cent discussion with its President, Mr. Man-fred Beitel, on EPTDA’s next Annual Conven-tion, its objectives and targets, and how theassociation is supporting its members fightthe ongoing financial tensions.

Let’s start with the hottest topic of thedecade! How is the ongoing crisis affectingPT-MC industry?This is one of the most severe crises ever in thehistory. And since our world is such a globalvillage, it has affected all of us in one way or

the other. There is no denying that PT-MC in-dustry, too, has felt the punch but as they say,we are “down but not under”. We have seenexceptional growth over the last 3-4 years,which has kind of spoiled us. The current cri-sis brings us the opportunity to look at doingthings differently and tightening the ship.

Has this affected the relationships be-tween Distributors and Manufacturers?On the contrary! I think that the current eco-nomic climate has brought Manufacturersand Distributors closer. This is the time to ben-efit from partnerships that have co-existedand co-evolved for decades. As an association,this is where we play a very essential role: oneof bringing people together. Our Annual Con-vention is one of the most valuable, cost-ef-fective and result driven platform where thetwo interest groups can meet formally and in-formally to discuss issues facing us all and finda professional and successful solution.

What role does an association like EPTDAplay, especially in times like these?We bring people together for a transparent di-alogue, we provide market intelligence, indus-try trends, data analysis, executive develop-ment opportunities, and we keep the indus-try moving in these tough times. It is essentialthat we as industry leaders do not lose focuson what’s important and what’s essential. Weare responsible to boost the confidence backin our part of trade and in a way in the Euro-pean economy, and as association, we canhelp in spreading that message acrossthrough valuable communication and infor-mation tools. We serve as the centre of infor-mation exchange: a very important role.

Would associations like EPTDA survive thisrecession?EPTDA is the ONLY association of its kind forEuropean Power Transmission & Motion Con-trol industry. It is the ONLY place where thetop level decision makers and industry defin-ers meet and discuss common issues. So notonly we will survive this recession, we willcome out stronger of it. This recession hasshown what a truly global world we live in.

There are some national associations andbodies, who will eventually disappear due tolack of international exposure and benefitsthey offer to their members, which brings upgreat opportunities for a global associationlike ours to attract more members.

EPTDA’s Annual Conventions are ac-claimed to be one of the best in Europe, ifnot the world. Tell us more!The EPTDA Annual Convention (and our an-nual All Committees Days) is a powerful basewhere entrepreneurs and business leaders ofour industry come together to define the fu-ture. We take great pride in the quality of ourmeetings which offers a careful selection ofspeakers from different walks of successfulbusiness enterprises, complemented with ahighly entertaining and pleasant social pro-gramme for partners and delegates alike. Weare also very conscious of the locations andvenues choice because we want our dele-gates and their partners to return every year.Call me emotional, but over the years, wehave emerged into one big family and it’sjust fantastic to see everyone back again yearafter year, and share some good times to-gether. And I hope we can do that again inR0me this year.

You just returned from a rather challeng-ing Hannover Messe. What is the gener-al feedback you received from yourmembers?We spoke to many of our members andpartners, who are obviously concernedabout the poor visibility into the future, es-pecially the ones associated with the auto-motive industry. Nevertheless, several newcompanies have expressed their interest tojoin EPTDA and benefit from its membershipprivileges. Good business is not alwaysabout making money, it is also about build-ing relationships. And Hannover Messe gaveus that opportunity to demonstrate to thenon-EPTDA members that as an association,we have done some good work over thepast years and created tangible benefits thatthey too can benefit from, especially in chal-lenging times like today.

EPTDA informs


The European Power Transmission DistributorsAssociation was strongly represented at this year’sHannover Fair from April 20 to 24.

SLI: 01711

When companies are cutting travel bud-gets and marketing spend due to shrink-ing markets, why should the members stillattend the 2009 Annual Convention?Because this is the place to be! We are all go-ing to meet in Rome and address some toughtopics, not only about fighting this crisis butalso about how to be prepared for the nextstretch (when it comes). Talking helps, theysay! The EPTDA Annual Convention is the on-ly stage to meet many new and old businesspartners from all across Europe and the Unit-ed States over 3 very powerfully chargeddays. This is one investment all our membersand future members should make, because itis about the future of our industry.

Tell us more about the theme of your 2009Annual Convention?We chose “Excellence in Relationship” longbefore the global economic crisis hit theworld. It’s fair to say that EPTDA Committeesand Council leaders could already foreseethat no matter whatever the future brings,powerful relationships is something that weshould always make a priority, and we did.Over the three days in Rome, we will alsolearn about how to protect our cash, growmargins and better manage our risks nowand in the future: hot topics on everyone’stop to-do list today.

Rome is turning out to be a hot destina-tion for you already! How many people areyou expecting?From the feedback we have received in Han-nover, and during our All Committee Days inMalta earlier in March, we are confident in thebenefits of our membership and loyalty of ourmembers. We can safely assume that onceagain we will have a dynamic presence at ourconvention with over 250 delegates. Rome isone of the most loved destinations in theworld, something people dream of visiting atleast once in their life, and we have all theconfidence that even more spouses and part-ners will join us this year in this historic city. Iam surely looking forward to it and hope towelcoming you all personally in Rome.

A high-value pavilionEPTDA’s joint pavilion with the PTDA (PowerTransmission Distributors Association), its sis-ter organisation in the USA, offered its mem-bers a unique platform to exhibit at preferen-tial conditions and yet guarantee themgreat visibility. The pavilion hosted 5 Euro-pean members – 2 of which enjoy a sharedEPTDA/PTDA affiliation.

The value of the pavilion was recognised byour exhibiting members:“It was a great experience that we shared to-gether, as members of EPTDA exhibiting withother members at the Hannover Messe. Youcould feel the “esprit de corps” atmosphereand how we, together with our association,maintain belief in our institution, industry andgoals; in ourselves and our others membercolleagues. EPTDA opens doors to the world -it’s a platform which creates opportunities forus,” says Pavina Martin, Georg Martin GmbH(EPTDA member since 2008).

And Ed Trainer, RBC Bearings (one of the firstto join EPTDA in 1998), to add – “the EPTDAhas been a beacon to many, and a source ofsupport to others. As any business, it is noth-ing, if it is not its people. EPTDA makes it easy

to work with, and is responsive to member re-quirements. EPTDA’s support on site helpedto make the week successful.”

The EPTDA/PTDA pavilion offers cost-effective,turnkey solutions for exhibitors; internet andmeeting facilities; logistic support; networkingplatform and a point of reference for all.

Successful Welcome ReceptionEPTDA and Power in Motion traditionally organise a Welcome Reception on its pavilionto welcome all its members and other key in-dustry professionals present on the fair-ground. This year, we welcomed no less than200 participants to celebrate together aHannover Fair beyond expectations. Mr. Man-fred Beitel, EPTDA President, was also there togreet EPTDA and other industry peers and kickoff the event.

On this occasion, EPTDA officially unveiled itsfresh-from-the-press convention brochureinviting all PT/MC decision makers to its nextannual event on September 23-25, 2009,in Rome, Italy. This was the official signalopening registrations for this exclusive profes-sional event, the one of its kind in the PT/MCindustry.

Market Outlook

PTDA members know that improving com-munication and building trust between trad-ing partners improves efficiency and lowersthe cost of operations, allowing them to de-liver exceptional customer service, innova-tive solutions and cutting-edge technologyto their mutual customers. In fact, in a mem-bership survey conducted in 2008, PTDAmembers identified distributor/manufactur-er relationships as one of the top externaland internal issues that will impact their busi-nesses over the next three to five years.

In continuation of its ongoing efforts to facil-itate the exchange of transactional informa-tion between distributors and manufacturers,the association released two publications.

Guidelines for Managing Back Orders:Minimizing the Impact

Developed by atask force of theIndustry Rela-tions Commit-tee, this publica-tion is the culmi-nation of workbegun last yearin investigatingthe major issuessurrounding the

communication and resolution of back or-ders. In the ideal world, every productwould be available where and when thecustomer needs it. In practice, there aretimes when the product needed isn’t readi-ly available and becomes “back ordered.”

At the most basic level, a back order usual-ly means a disappointed customer. Han-dled poorly, a back order can escalate intoa situation in which trust is questioned andbusiness is lost. Recognizing that relation-ships between distributors and manufac-turers can be improved with a comprehen-sive process for communicating and resolv-ing back orders, a task force was appointedto uncover the issues surrounding back or-ders. While the actual resolution of back or-der issues rests with the distributor and

manufacturer involved, the guidelines de-veloped by the task force can assist in min-imizing the effect a back order has on busi-ness and business relationships. Their find-ings as well as examples of how these is-sues have been addressed by channel part-ners within the PT/MC industry are includ-ed in this publication.

Guidelines for Successfully Sharing Costof Goods Sold (COGS) Information

The Industry Re-lations Commit-tee and theM a n u f a c t u re rCouncil com-bined forces ona joint task forceto uncover waysin which thesharing of costof goods sold

(COGS) information can be beneficial forboth distributors and manufacturers.

Distributors are familiar and comfortablewith receiving information from manufac-turers on an almost constant basis - productand price information updates, new prod-uct announcements and back order notices.There are also times when information goesthe other way - from distributor to manufac-turer. For a manufacturer, information fromtheir distributors about who is buying theirproduct can assist in creating products thatmeet market demand, uncovering new ap-plications for existing products and fairlycompensating their employees.

The guidelines use the COGS Format adopt-ed by PTDA a few years ago and improvesits use as a business tool with additional ma-terials to encourage distributors to provideCOGS data and to encourage manufactur-ers to make use of the data in a way thatbenefits the entire supply chain.

The first two quarters of 2008 witnessedcontinued rapid growth; however, thesecond half of 2008 saw the start of a sig-nificant slowdown and this has contin-ued through to the first quarter of 2009.Data obtained for the last quarter of2008 and the first quarter of 2009 indi-cate a decline in demand for motordrives across all regions. The markets formotion controls and low voltage AC in-duction motors are also expected to ex-perience similar levels of decline.

There are several reasons behind the ex-pected contraction in markets that haveexperienced record double-digit growthover the past three years. Most notably,machinery markets in Europe, Asia, andthe Americas are performing worse than

predicted, with many experiencing dra-matic declines in order intake during thelast two quarters. During the fourthquarter of 2008, GDP declined by 1.6% inthe US, and 1.5% in the EU, while Japanexperienced a contraction of 3.2%. Chi-na, the only major region expected to ex-perience GDP growth in 2009, reported a6.1% GDP increase for the first quarter of2009. The fact that GDP growth is ex-pected to remain positive in the countryis attributed to the effectiveness of thestimulus package enacted by the Chi-nese government that focuses heavily onenergy efficiency and many of the indus-try sectors that are significant users of in-dustrial automation products such asmotors, drives, and motion controls. As aresult, the Chinese drives market is fore-cast to experience positive growth in2009 in the area of 5%, with the marketsfor motors and motion control productsalso expected to fare better than in oth-er regions.

Positive growth in key industry sectorssuch as the utilities, food & beverage,and renewable energy industries is ex-pected to slightly offset declines in met-al processing, textiles, commercial HVAC,and other industries. However, anotherreason for the market contraction is dueto ongoing problems with capital lend-ing. Tight lending conditions are havingan impact on these previously stronggrowth sectors including renewable en-ergy. Several component suppliers andwind turbine manufacturers exhibitingat the Hannover Industrial AutomationShow in April of 2009 mentioned thatwhile demand for wind projects is stillabundant, many of the projects have en-countered significant delays due to re-stricted lending by banks. This has in turncaused problems with securing fundingfor large scale and very costly wind andsolar farm projects.

Similar to the motor drives market, theworldwide market for motion controlequipment experienced robust revenuegrowth in 2007, increasing by 11.9% over2006 levels. All regions and industry seg-ments exhibited strong growth during theyear and total worldwide revenues for themotion control products market estimatedat $9.9 billion. The double digit growth rateswitnessed by the motion controls marketover the past few years have been driven bywidespread use of servo systems and posi-tion control hardware in machine tools, aswell as semiconductor, robotics, packaging,material handling, food & beverage, andprinting machinery. While the economicslowdown is expected to affect nearly all in-dustry sectors that use motion controlproducts, the degrees of effect will vary,with some industry sectors being hit harderthan others. Overall, the market for motioncontrols is forecast to decline by 7.2% in rev-enue terms in 2009.

The low voltage AC induction motors mar-ket will also be affected by the economicslowdown in key industry sectors and low-er capital spending as a result of tight cred-it, to the tune of declining by 7.3% in termsof revenues in 2009. The market will also beaffected by government-led initiatives fo-cusing on utilization of higher efficiencymotors. Governments in the US, Europe,and other regions have introduced legisla-tion, or encouraged voluntary industryagreements, that will dramatically shift themarket away from EPAct and EFF2 motors tohigher efficiency motors. Currently, threequarters of the world’s industrial AC induc-tion motors being sold do not meet the ef-ficiency standards that will be required un-der these new agreements. As a result, thelower efficiency product will continue todecline, but rapid growth is forecast for highefficiency motors.

Pivotable belt conveyorfor mobile application

The mobile, pivotable belt conveyors are con-ceived primarily for production processes inwhich rejections occur frequently. So often inproduction the problem arises that when a plantis started, qualitatively inferior products arise.By virtue of their high degree of manoeu-vrability, the belt conveyors can be manual-ly pivoted to the side and the product shunt-ed off to another location. The pivoting deviceis designed for all sorts of processes, becausethe transported material intake height is vari-able, being possible even a height of only300mm.Geppert-Band SLI: 01604

Coaxial drive silent and powerful

The low noise coaxial-drive (Koaxdrive) KD32 planetary gearhead is setting new standardsin operating noise and torque levels. Mea-suring 32mm in diameter and with a torqueof 6.5Nm, it is ideal for use in noise-sensitive,highly demanding applications. It combinesthe best of two proven gearing technologies,namely worm and planetary gearing. Specialattention has been focused on the first gearstage, as this is where the greatest peripher-al speeds occur and therefore noise. The com-pletely new, patent-protected design has en-abled reduction of noise.Maxon Motor SLI: 01623

Timing belt linear unitswith safety locking system

For Duo-Line seriesaxes of80mm orgreater, thelocking sys-tems forlinear sys-t e m s ,which isavailable asan option, has been integrated in the guideprofile and carriage. With this solution the en-tire holding device mechanism remains outof sight and is protected to the greatestpossible extent against external influences.For all other linear units that are typicallyused as vertical axes, external add on lock-ing systems are available. All locking sys-tems work safely and reliably, even where thereare oil or grease contaminations. The maxi-mum clamping force is adjustable and ismatched to the mechanical load capacity ofthe linear axes.RK Rose + Krieger SLI: 01686

Linear drive module350 micron position accuracy

The Ser votube Module combines amagnetic design and built-in position sen-sor to provide 350 micron position accura-cy. I ts industry standard 1V peak-peaksine/cosine output provides convenientfeedback for many standard rotary servomotor drives. Using self-tuning Xenus andAccelnet servo amplifiers with PC-basedmotion engineering tools, engineers canget off to a flying start with any application.

Popular drives from manufacturers such asSiemens, Parker, B&R are also supported.Electro-motive force is transferred directlyto the forcer carriage without any physi-cal contact; unlike ballscrews there are noenergy storing components to introduce po-sitioning errors caused by wind-up or back-lash. The linear drive module can thereforeachieve 12 micron repeatability withoutany additional engineering. For higher pre-cision applications, the position resolutioncan be upgraded to 1 micron resolutionwith an integrated optical encoder.Copley Motion System SLI: 01610

Servo drivewith integrated software

The Compax3 family of single and multi-ax-is servo drives can operate at between 1 and110kVA, and are suitable for use with allcommon types of motors and actuators, in-cluding sine commutated synchronousand asynchronous motors, torque motors,linear servo motors and voice coil motors.Similarly, the Compax3 system supports avariety of different feedback technologiessuch as resolvers, sine cosine in single or mul-ti-turn versions, Hiperface or EnDat inter-faces, analogue and digital hall sensors,and distance coded, rotary and linear en-coders. As an open system, Compax3 canbe used with Profibus, CANopen, DeviceNet,EtherCAT and Powerlink protocols, and canalso be supplied with a real-time drive busfor dynamic, multi-axis synchronised appli-cations. The Integrated Engineering Toolsoftware uses PLCOpen Motion ControlFunction Blocks and wizard technology tomake setup, configuration and subsequentadjustments quick and simple.Parker Hannifin SLI: 01600

Gear racks geometric pression permits faster drives

The gear racksare used in par-ticular in toolmachines, han-dling, in convey-or, handling andlinking technol-ogy, and in ro-bots. The deci-sive quality criterion for these components isthe precise production of the gearing andthe entire gear rack body respectively. In ad-dition to many years of experience and the useof high-quality raw materials until hardening,grinding machines that work to a precisestandard are essential for the gear rack bodyand gearing. To ensure the perfect grinding ofthe gear racks, the drive specialists fromNördlingen are continually investing in state-of-the art production technology. One of thebenefits for the users is a much reduced noisedevelopment. The acceleration and speed ofthe drive are also increased. Spacing deviationsare virtually negligible. The wear and tear is low-er, and efficiency increased. The effort requiredfor assembly and the replacement of compo-nents is reduced further.SPN Schwaben Präzision SLI: 01684

Incremental encoderin stainless steel

The Sendix5006 incre-mental en-coder in stain-less-steel isthus suitablefor use in de-manding ap-plication areas that require long-term durabil-ity. Sectors that can profit from this latest de-velopment include, for example, the food in-dustry, which has to use aggressive substances,not only because of strict hygiene regula-tions but also due to foodstuff ingredientssuch as brine or lactic acids; the packaging andutility vehicle sectors will benefit in a similar way,especially from the specific power spectrum.A sizeable contribution to the durability ofthe stainless-steel encoder is made by itshigh-grade Viton seals. These ensure imperme-

ability, even when subjected to aggressivesubstances or variations in temperature. Thehigh IP67 level of protection as well as the widetemperature range go one stage further inprotecting against breakdowns in the field. TheSendix 5006 incremental encoder can easilyhandle large fluctuations in temperature, from-40°C up to 85°C. Fritz Kübler SLI: 01697

Tilt sensorIP67/IP69K-rated

The PTAM2 se-ries has rangesfrom ±5° to±180° for singleaxis and from±5° to ±60° fordual axes in a ro-bust, IP67/IP69Krated all-metalhousing. The in-dustrial grade sensor provides a high resolu-tion, linear output signal that is proportionalto the inclination angle. The PTAM2 series hasbeen tested to withstand harsh conditionswhich makes it suitable for a range of applica-tions such as factory automation machines androbotics, mobile cranes, draw bridges, ad-justable platforms and off-highway construc-tion equipment. It is available with four differ-ent absolute analogue outputs: 0.5-10V, 4-20mA, voltage sine(x) and CANopen with a typ-ical resolution of 0.05°. Limit switch outputs arealso available. The output signal responsetime is available from 0.1 – 2.0 seconds, in 0.1second increments. The measurement rangesare available from ±5° to ±180° in 5° increments.The compact 36mm diameter housing with ser-vo flange mounting allows for quick and easyinstallation.ASM SLI: 01683

Cylindrical sensors for narrow spaces

The photoelectric sensors FQ series has beendesigned for applications with extremely nar-row spaces. The photoelectric sensor’s bodypresents a noticeably shorter length – about30% less than large consumption cylindricalversions – ensuring good performances. Theaxial or right angle optic and the M12 output,with axial or right angle cable, make them

suitable for any sizeneed. High perform-ances are supportedby a high level of relia-bility: the photoelec-tric sensor is manufac-tured both with plasticand metallic housing,completely fulfilled of resin, able to resist to theharsh working conditions. The following mod-els are available: direct diffusion (with sensingdistance up to 1,500mm), polarized (up to4m), retro-reflective (up to 5m) and emitter/re-ceiver through-beam (with sensing distanceup to 20m). The installation is simple and im-mediate and the models equipped with theright angle optic, with mirror deflector, can beinstalled in conveyors’ or roller tables’ guideswithout any further side encumbrance.M.D. Micro Detectors SLI: 01598
