Otis GeN2 Comfort system: The Benefits

➊ Replacing conventional steel ropes with smooth, polyurethane-coated

steel belt results in a quieter and smoother ride.

➋ A gearless machine controlled by a closed loop variable frequency drive pro-

vides a comfortable ride with outstanding stopping accuracy.

➌ A low-inertia gearless machine with a permanent magnet (PM) synchronous

motor means energy savings and reduced operating costs.

➍ The belts and gearless machine with sealed-for-life bearings require no

addition of oil or polluting lubricants and thus protect the environment.

➎ The interaction of the flat, coated steel belt with the smooth-surface

crowned sheaves results in reduced belt wear.

➏ A flexible belt means a more compact machine which removes the need

for a machine room and reduces building costs.

➐ Otis’ PULSETM system continually monitors the status of the belt’s steel cords

24h/7d.

➑ A patented battery-operated rescue system with electronic speed moni-

toring enables safe and fast rescue of a trapped passenger in the event

of a power failure.

➒ With the machine on the rails, loads are transferred down to the pit thereby

improving interface and reducing structural building costs.

➓ GeN2 Comfort technology enables rapid, safe and controlled installation

that doesn’t interfere with other building trades.

� CONVENTIONAL STEEL ROPES

The stiffness of conventional steel ropes requires a largebending radius.

� FLEXIBLE STEEL BELTS

The polyurethane-coated flat steel belt is up to 20% lighterand lasts up to 3 times longer than conventional ropes. Itsflexibility results in a much smaller bending radius.

� COMPACT GEARLESS MACHINE

A sheave - which can be as small as 8 cm in diameter -hasallowed Otis to design a machine that is up to 70% smallerthan conventional machines.

� MACHINE ROOM SYSTEM

In a conventional system, the large machine and controller requirea machine room typically positioned above the hoistway. Allbearing loads are supported by the building structure.

� MACHINE ROOMLESS SYSTEM

The compact GeN2 gearless machine does not require amachine room and can be easily positioned on top of the carand counterweight rails. This means all bearing loads can betransferred to the pit, thus reducing structural building costs.

� CONVENTIONAL MACHINE

The broad bending radius of steel ropes requires a largemachine with a sheave that is typically 50-60 cm indiameter.

UNRIVALLED RIDE QUALITY

Replacing metal ropes with smooth flatbelts means a quieter and smoother rideEnhanced ride quality is achieved through thecombination of a number of factors: Otis’ flatpolyurethane-coated steel belt which eliminatesthe metal-to-metal effect of conventional ropestogether with the specially designed crowned-surface sheaves (with no twisting of the beltthrough 180°) results in quiet operation.

The gearless machine combined with an analogload-weighing device and a closed-loop variablefrequency drive with vector control enable asmooth ride with outstanding stopping accuracy(within +/- 3 mm at every landing). Cumulatively,these features have allowed Otis to achieve aquiet, smooth and comfortable ride experience.

With appropriate treatment of the hoistwaywalls, the low noise gearless machine mountedon isolation rubber pads reduces vibration tothe building and keeps average noise levels inadjacent rooms to below 30 dB(A) - incompliance with strict EU building regulations.

A HIGHLY EFFICIENT MACHINE

A flexible belt means a more compactmachineThe low inertia gearless machine with sealed-for-life bearings is equipped with a highly efficientPM synchronous motor of radial construction.

The result is a machine which is up to:

• 50% more efficient than conventional gearedmachines.

• 10% more efficient than conventional gearlessmachines with induction asynchronousmotors.

• 15% more efficient than other machines withPM motors of axial construction design.

ENVIRONMENTALLY FRIENDLY

Lubrication-free and more energy efficientNeither the belts nor the gearless machinewith sealed-for-life bearings require any formof polluting lubricants.

The low-inertia gearless PM machine, controlledwith a closed-loop variable frequency drive withvector control, results in:

• Substantial energy cost savings whencompared with conventional machines.

• Reduction of power installed thereby reducingoperational cost.

• Lower starting and nominal currents thusreducing the feeder size lines and installationcosts.

Additionally, the VF drive suspend-mode featurefurther reduces energy consumption.

INCREASED RELIABILITY

Reliable by design and durable byconstruction The long-lasting coated steel belt, thesmooth crowned sheaves and the reductionof moving parts in the gearless machinedramatically reduce wear and increasedurability.

Reliability and safety are further enhancedwith Otis’ PULSE electronic system whichcontinually monitors the status of the belt’ssteel cords 24h/7d. Contrary to currentvisual inspections of conventional steelropes, the Otis PULSE system automaticallydetects and informs Otis technicians on thequality of the belt cords, thus eliminatingdowntime and greatly enhancing thereliability of the inspection.

SAFETY FEATURES

For lift users and service technicians

• Door Deterrent Device If the car is stopped between floors, adeterrent device prevents the car door fromopening. Hence a person cannot take therisk of exiting.

• Hoistway Access Detection To protect a person entering the hoistway, aspecial safety feature prevents the lift fromoperating after a landing door has beenopened.

• Rescue SystemA patented, battery-operated rescue systemwith electronic speed monitoring enablesthe safe and fast rescue of trappedpassengers in the event of a power failure.

• LAMBDA™ 2D – Entrance Protection(optional)A screen of infrared beams acts as an invisiblesafety curtain. When an obstacle breaks thisscreen, the sensitive LAMBDA 2 systemdetects it and immediately reopens the doors.

• Stopping AccuracyThe belt’s reduced stretch compared toconventional steel ropes together with aclosed loop VF control results in outstandingstopping accuracy (within +/-3 mm at everylanding).

• Machine Brake System To further improve safety, the machine’sdual brake system is equipped with twoswitches to prevent the lift from movingbefore the brake is fully released.

RAPID INSTALLATION

A controlled process minimizes installationtime and improves safetyWith all major components located inside thehoistway, the streamlined installation processof the GeN2 Comfort lift has minimal impact onbuilding construction and other trades.

The machine is integrated on top of the railsthus virtually eliminating the interface withthe building. The car serves as a constructionplatform for rapid installation and alignmentof rails.

Finally, the controller and drive are integratedinto a single cabinet which is factory pre-tested.
