Your advantages when using Electromagnetic
ROBATIC®-Clutches, ROBA®-quick Brakes and
ROBA®-takt Clutch Brake Units
• Easy integration into your machine:The optimised magnetic circuit minimises themagnetic stray flux. The high power density and torque security based on it allow compact dimensions and an easy integration in your construction.
• High reliability and operational security:The switching behaviour is constant during the whole service life. Therefore, the positioningaccuracy and reliability of the clutches or brakes respectively and herewith operational security ofyour machine are increased.
• Less operating expenses and maintenancecharges:The large friction surface and the smooth switchingbehaviour increase the wear resistance, therefore,the clutches and brakes are maintenance-free untilthe friction faces are worn down.
• Increase of the productivity:Short switching times allow high switching frequency and increase the productivity of yourmachine.

ROBATIC® Electromagnetic Clutch
Definition of termsThe torque (nominal torque)(= switching torque) is the torque acting on the shafting with a slippingclutch or brake.
The transmittable torqueis the largest torque with which the closed clutch or brake can beloaded without an occurrence of slipping.
At a rated-load operating temperature the permanent temperatureis achieved. This temperature is the amount from the determinedover-temperature and the reference temperature.
Protection class I is not only based on the basis isolation, but thatall conductive magnetic parts must be connected with the protectiveconductor of the fixed installation. In this case, if the basis isolationfails, no contact voltage can remain existing.
The relative switch-on duration is the ratio of switch-on duration tothe cycle duration in percentage (% switch-on duration).
Description of the unitThe catalogue values are reference values, which can deviate inindividual cases.When selecting the clutch or brake, mounting situation, torquefluctuations, permissible friction work, behaviour during run-in, wearand ambient conditions are to be carefully checked and agreed withthe unit manufacturer.The mounting and connecting dimensions at the site of installationmust match to the size of the units.The clutches and brakes are designed for a dry running. They achievethe catalogue-torque, when the friction linings are run-in. Normallythese are approx. 100 switchings with a dynamic operation.In a new condition approx. 50 % of the catalogue-torque (Mü) istransmitted. Clutches or brakes used statically or quasi-statically (i.e.small friction work) do not achieve the torque (Mü) indicated in theTables.This case is given if the clutch or brake falls below the speed orfriction work (Qa) indicated in Table 1. Should oil, grease or similarmaterials come in contact with the friction surfaces the torque couldbe reduced drastically.When switching off the units voltage peaks can occur due to themutual inductance of the magnetic coils which can cause a damageof the units in the extreme case. Therefore, the overvoltage is to bedamped by a “protective wiring”.The surfaces of the clutches and brakes are protected againstcorrosion. Provide additional necessary safety measures againstcorrosion, if they are used under extreme ambient conditions or in theopen with direct atmospheric influence. The connecting cables orwires of the clutches and brakes have a sheathing on silicone basis,which is not resistant to all materials. The compatibility is to beexamined when contacting chemical materials. The clutches andbrakes are designed for a relative switch-on duration of 100 %.

ROBATIC® Electromagnetic Clutch
Constant switching performancethroughout the total service life
High torque securitydue to an optimised magnetic field and the new design of the ROBATIC®-clutch. Therefore, higher capacities due to fewmagnetic field losses.
Half the weardue to large friction surfaces and smooth switching behaviour the ROBATIC®-clutch has ahigher wear resistance (approx. 100 %).
Low noise
Short switching times/high switching frequencies
Correct function until end of wear
Large permissible shaft diameters due to largeinternal diameters of the magnetic coil bodies.

ROBATIC® Electromagnetic Clutch
FunctionROBATIC®-clutches are „energise to engage“, electromagneticpole face units.
If a DC voltage is applied to the magnetic coil (1) a magnetic fieldis formed, the armature disc (3) is attracted to the rotor (2) andfriction lining (4). The torque is transmitted via a friction connection.
The torque is transmitted from the drive element (6) via the armature disc (3) and the rotor (2) to the output shaft (7).
After having de-energised the coil, the membrane spring (5) draws back the armature disc (3) to the drive element (e.g. beltpulley), and the torque transmission is then disconnected.

Table 1
The dimension „a“ (Fig. 1) is to be adjusted according to the table 1.Care must be taken to ensure that the shaft is fastened axially,since, otherwise the dimension „a“ will change and cause therotor to brush against the armature disc or the coil carrier. The airgap „e“ is chosen, that a banding of the rotor at the coil carrier isnot possible when keeping the permissible center deviations Vand V1 (see table technical data).
Construction:ROBATIC®-Electromagnetic clutches are manufactured to IP 54specification and the insulation class F to 155 °C for coil, moulding compound and power cable as well as insulation classB 130 °C for the magnet coil plastic-extrusion-coated. The friction linings are asbestos free, the surface of coil carrier, rotorand flange hub are phosphated. The armature disc is nitrited andthe transmitting spring is made of stainless steel. The drive elements should be made of magnetically poor transmittingmaterial to avoid magnetic field losses and subsequent powerreduction.
ROBATIC® clutches are used for dry running. The torque is transmitted by connection of the armature disc on the iron polesand friction lining of the rotor.
When coupling two shafts the eccentricity „V“ of the shafts according to table 2 must not be exceeded. The larger the displacement „V“ the greater the friction surface becomes. In thecase of this arrangement care must be taken that both shaftshave no axial play since, otherwise, a brushing of the rotor wouldalso be possible. The flange hub is kept axially by means of a setscrew (set at 90 ° to the key). The „V“-values are indicated againin the technical data of the individual clutches.
Table 2
Please note:The running-in instructions or min. speed are to be observed (seepage 3).
The friction surfaces have to be absolutely free of oil and grease,otherwise, the torque drops significantly. The air gap „a“ (Fig. 1)has to be checked periodically. The clutch does not function correctly, if the max. working air gap is exceeded (see table 1,page 18).
Assembly and maintenance should be made by well trained specialists.

ROBA®-quick Electromagnetic Brakes
FunctionROBA®-quick are „energise to engage“, electromagnetic poleface brakes. If a DC voltage is applied to the magnetic coil (1)a magnetic field is formed, and the armature disc (3) is attracted to the coil carrier with friction lining (4). The braketorque runs from the coil carrier (2) via friction lining (4), armature disc (3) and membrane transmitting spring (5) to theflange and the shaft.
If the magnetic coil is de-energised the membrane transmitting spring (5) draws the armature disc (3) back to theflange (6). The brake is released and the shaft (7) can run freely.

Table 1
The dimension „a“ (Fig. 1) is to be adjusted according to thetable 1. Care must be taken to ensure that the shaft isfastened axially, since otherwise the dimension „a“ will change and cause the armature disc to band against coil carrier.
Construction:ROBA®-quick Electromagnetic brakes are manufactured to IP 54 specification and the insulation class F to 155 °C for coil,moulding compound and power cables as well as insulationclass B 130 °C for the magnetic coil plastic extrusion-coated.The friction linings are asbestos free, the surface of coil carrier and flange hub are phosphated. The armature disc isnitrated and the membrane spring is made of stainless steel.
ROBA®-quick brakes are used for dry running. The torque istransmitted by friction between armature disc and the ironpoles and friction lining surface of the coil carrier.
When braking the eccentricity „V“ according to table 2 mustnot be exceeded. The larger the displacement „V“ the morethe torque decreases and the hotter the friction surface becomes. In the case of arrangement according to table 2care must be taken that the coil carrier and shaft have no axial play, since otherwise a brushing of the coil carrier wouldbe possible. The flange hub is kept axially by means of a setscrew (set at 90° to the key). The „V“-values are indicatedagain in the technical data of the individual brakes.
Table 2
Please note:The running-in instructions or min. speed are to be observed(see page 3).
The friction surfaces have to be absolutely free of oil and grease as otherwise the torque drops significantly. The air gap„a“ (Fig. 1) has to be checked periodically. The brake does notfunction correctly if the max. working air gap (see table 1,page 27) is exceeded.
Assembly and maintenance have to be made by well-trainedspecialists.

AssemblyClutch Brake Unit with flange:The shafts, locating spigots and shoulders, bolt holes, PCD’sand flanges are to IEC standards.Input and output sides can be fitted with the correspondingflanges of motor, gear reducer or other transmission elementsas shown in Fig. 1 without problems.
Fig. 1
Fitting of transmission elements:The drive elements are pushed onto the respective shafts andsecured axially via an axial securing screw and washer, theshafts being drilled and tapped accordingly, as shown in Fig. 2.
For the combination motor shaft - ROBA®-takt hollow shaftthe motor shaft must slightly be greased to prevent frictionalcorrosion.
Extensive force or hammer blows can damage the bearings.
Radial loads acting on the shaft via the drive elements mustnot exceed the maximum allowable values (see heading „permissible shaft load“).
Should both radial and axial loads be present on the shaft, thepermissible loads must be determined - please contact ourengineers.
Permissible shaft loads
Fig. 4
The drive elements located on the shafts exert a radial loadduring operation which has to be absorbed by the bearingsof the unit. The load is limited by the required life of the bearings and strength of the shaft, Table 1.

ROBA®-takt switch gear Type 014.000.2
Dimension (mm)
Application
Start – stop – and positioning by switching and controlling of mayr®
clutch brake combinations and mayr® ROBA®-takt clutch brakeunits.
Function
The ROBA®-takt switch gear operates according to the principle ofpulse width modulation with a frequency of 18 kHz. The corresponding coil will be energised by actuating the sensor forclutch and brake. An overtemperature monitor protects the unit fromoverheating. In case of a temperature of >80 °C the coil voltage isswitched-off. The LED “overtemperature unit” lights red.A delay time prevents simultaneous appearance of clutch and braketorques.An overexcitation during switching-on reduces the attraction time of the coil and allows an exact switching and positioning.

ROBA®-takt circuit module Type 004.000._
ApplicationStart and stop of mayr® ROBA®-takt circuit modules and mayr®-clutch brake combinations.Alternating switching of 24 VDC coils, if a 24 VDC power supply isavailable.
Function1 sensor -actuated- clutch is energisedoperation -not actuated- brake is energised
The respective control of the clutch or brake is indicated via LED. The ROBA®-takt circuit module has no over-excitation function.
The brake has priority: The brake is energised independent fromthe sensor position when switching on the 24 VDC power supply. Thecoil is energised with the 24 VDC power supply.
Delay time: To avoid simultaneous interaction of clutch and brakingtorques a delay time of 0 – 100 ms between clutch and brakingtorques can be set, which acts according to the respective pickupand drop-out times of the coils (see switching time table). The settingis made via the potentiometers Ku = clutch (P2) and Br = brake (P1). Factory default setting is 0 ms.
