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 the magnetic 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 positioning accuracy and reliability of the clutches or brakes respectively and herewith operational security of your machine are increased.

• Less operating expenses and maintenance charges:The large friction surface and the smooth switching behaviour increase the wear resistance, therefore, the clutches and brakes are maintenance-free until the friction faces are worn down.

• Increase of the productivity:Short switching times allow high switching frequency and increase the productivity of your machine.

All products are subject to comprehensive inspections and tests regarding loads. Only after having passed the strongest long-time tests and when they fully meet all the technical requirements and proof their reliability they are included in our delivery programme.

Please Observe:According to German notation, decimal points in this document are represented with a comma(e.g. 0,5 instead of 0.5).

Product quality

No delivery leaves our company without first being subjected to a careful quality inspection, so that customers are able to rely 100 % on mayr products. If requested, we adjust your clutches and brakes to the exact values required, and confirm the product characteristics using an inspection form.

Quality management

The term "quality" refers at mayr® to products and service performance. The certification of our quality management confirms the quality-consciousness of our colleagues at all levels within the company. Our management system is certified according to DIN EN ISO 9001:2000 (quality) and DIN EN ISO 14001 (the environment), and complies with the OHSAS 18001/OHRIS (employment protection) requirements.

Electromagnetic Clutches and Brakes

Description and Operational Conditions

1. The catalogue values, in particular the values for the nominal torque, are reference values and may deviate in individual cases.

�. During dimensioning, please contact the manufacturers for consultation on installation conditions, torque fluctuations, permitted friction work, run-in behaviour, wear and ambient conditions.

�. The clutches and brakes are designed for dry running. If the friction surfaces come into contact with oil, grease or similar substances, there may be a severe decrease in torque.

4. When the devices are switched off, voltage peaks may occur due to the counter-induction on the magnetic coils, causing in extreme cases damage to the magnetic coil and therefore to the components. For this reason, excess voltage must be damped using a suitable “protective circuit” (e.g. using a varistor).

5. The surfaces on the clutches and the brakes are corrosion-protected except for the friction surfaces. However, in operation in extreme ambient conditions or in outdoor conditions with direct weather influences, additional protective measures are necessary.

6. The connection cable or connection strands on the clutches and brakes have a surface coating which is not resistant against all influences. After contact with chemical substances, please check compatibility.

7. The clutches and brakes are designed for a relative duty cycle of 100 %.

Torque Characteristics

In new condition, c. 50 % of the catalogue nominal torque (M2) is transmitted.

The components reach the catalogue nominal torque when the friction surfaces are run in. As a rough guideline value, c. 100 – �00 switchings in dynamic operation, a typical speed (c. 50 to 1000 rpm) and a medium friction work (see Table 1) can be given.Longer slipping of the clutch or brake is to be avoided, especially at low speeds, as this can cause scoring formation and therefore damage to the friction surfaces.Clutches or brakes used in static or virtually static operation do not reach the nominal torque (M�) given in the Technical Data.

If requested, the clutches or brakes can also be run in at the place of manufacture. This is most expedient for the Type 540.140 with complete bearing.However, the Types 500.1_ _ and 5�0.1_ _ can also be run in under certain conditions. For this, please ensure exact installation customer-side according to the regulations in order to reproduce the friction conditions as exactly as possible. At the same time, the “friction carbon” produced must not be rubbed off.If the clutch is run in to the nominal torque at the place of manufacture and then operated in static or virtually static mode, please allow for a drop to c. 60 – 70 % of the nominal torque. This is the case if the clutch or brake falls below the speed or friction work (Qa) given in Table 1.For static and virtually static applications, we therefore recommend our, „double-cut designs“, construction series 500.�_ _.0 (available on demand).

Run-in Conditions

For running in, different procedures can be used according to the Type design. The respective application should also be individually taken into account.An “artificial” run-in is to be carried out if a run-in procedure is not possible in the machine due to the type of application (see section “Torque Characteristics”), e.g. due to insufficient friction work, speed or switching frequencies.

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 few magnetic field losses.

Half the weardue to large friction surfaces and smooth switching behaviour the ROBATIC®-clutch has a higher wear resistance (approx. 100 %).

Low noise

Short switching times/high switching frequencies

Correct function until end of wear

Large permissible shaft diameters due to large internal diameters of the magnetic coil bodies.

FunctionROBATIC®-clutches are „energise to engage“, electromagnetic pole face units.

If a DC voltage is applied to the magnetic coil (1) a magnetic field is formed, the armature disc (�) is attracted to the rotor (�) and friction lining (4). The torque is transmitted via a friction connection.

The torque is transmitted from the drive element (6) via the armature disc (�) and the rotor (�) to the output shaft (7).

After having de-energised the coil, the membrane spring (5) draws back the armature disc (�) to the drive element (e.g. belt pulley), 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 the rotor to brush against the armature disc or the coil carrier. The air gap „e“ is chosen, that a banding of the rotor at the coil carrier is not possible when keeping the permissible center deviations V and V1 (see table technical data).

Construction:ROBATIC®-Electromagnetic clutches are manufactured to IP 54 specification and the insulation class F to 155 °C for coil, moulding compound and power cable as well as insulation class B 1�0 °C for the magnet coil plastic-extrusion-coated. The friction linings are asbestos free, the surface of coil carrier, rotor and flange hub are phosphated. The armature disc is nitrited and the transmitting spring is made of stainless steel. The drive elements should be made of magnetically poor transmitting material to avoid magnetic field losses and subsequent power reduction.

ROBATIC® clutches are used for dry running. The torque is transmitted by connection of the armature disc on the iron poles and friction lining of the rotor.

When coupling two shafts the eccentricity „V“ of the shafts according to table � must not be exceeded. The larger the displacement „V“ the greater the friction surface becomes. In the case of this arrangement care must be taken that both shafts have no axial play since, otherwise, a brushing of the rotor would also be possible. The flange hub is kept axially by means of a set screw (set at 90 ° to the key). The „V“-values are indicated again in the technical data of the individual clutches.

Table �

Please note:The running-in instructions or min. speed are to be observed (see page �, Section „Torque Characteristics“ and „Run-in Conditions").

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.

FunctionROBA®-quick are „energise to engage“, electromagnetic pole face brakes. If a DC voltage is applied to the magnetic coil (1) a magnetic field is formed, and the armature disc (�) is attracted to the coil carrier with friction lining (4). The brake torque runs from the coil carrier (�) via friction lining (4), armature disc (�) and membrane transmitting spring (5) to the flange and the shaft.

If the magnetic coil is de-energised the membrane transmitting spring (5) draws the armature disc (�) back to the flange (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 the table 1. Care must be taken to ensure that the shaft is fastened 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 insulation class B 1�0 °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 is nitrated and the membrane spring is made of stainless steel.

ROBA®-quick brakes are used for dry running. The torque is transmitted by friction between armature disc and the iron poles and friction lining surface of the coil carrier.

When braking the eccentricity „V“ according to table � must not be exceeded. The larger the displacement „V“ the more the torque decreases and the hotter the friction surface becomes. In the case of arrangement according to table � care must be taken that the coil carrier and shaft have no axial play, since otherwise a brushing of the coil carrier would be possible. The flange hub is kept axially by means of a set screw (set at 90° to the key). The „V“-values are indicated again in the technical data of the individual brakes.

Table �

Please note:The running-in instructions or min. speed are to be obser-ved (see page �, Section „Torque Characteristics“ and „Run-in Conditions").

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 not function correctly if the max. working air gap (see table 1, page �7) is exceeded.

Assembly and maintenance have to be made by well-trained specialists.

AssemblyClutch Brake Unit with flange:The shafts, locating spigots and shoulders, bolt holes, PCD’s and flanges are to IEC standards.Input and output sides can be fitted with the corresponding flanges of motor, gear reducer or other transmission elements as shown in Fig. 1 without problems.

Fig. 1

Fitting of transmission elements:The drive elements are pushed onto the respective shafts and secured axially via an axial securing screw and washer, the shafts being drilled and tapped accordingly, as shown in Fig. �.

For the combination motor shaft - ROBA®-takt hollow shaft the motor shaft must slightly be greased to prevent frictional corrosion.

Extensive force or hammer blows can damage the bearings.

Radial loads acting on the shaft via the drive elements must not exceed the maximum allowable values (see heading „permissible shaft load“).

Should both radial and axial loads be present on the shaft, the permissible loads must be determined - please contact our engineers.

Permissible shaft loads

Fig. 4

The drive elements located on the shafts exert a radial load during operation which has to be absorbed by the bearings of the unit. The load is limited by the required life of the bearings and strength of the shaft, Table 1.

Table-1 max. permissible radial load Fmax limited due to the strength of the shaft, application of load midway along shaft.

The application of load is assumed to be midway along the shaft, determining the acceptable radial load. In case there are additional axial loads, an extensive calculation is necessary (please contact our sales offices).

The acceptable radial loads mentioned in Table � refer to a speed n = 1500 rpm and a bearing service life Lh = 10 000 hours.

ROBA®-takt Control unit Type 014.000.2

Application

This unit is used to start, stop and to position by switching and controlling the mayr®-clutch-brake units.

Function

The ROBA®-takt control unit operates according to the principle of a clocked switching controller with a frequency of 18 kHz. Its coil is energised by actuating the sensor for clutch and brake. A temperature monitor protects the unit from overheating. Should the temperature exceed >80 °C, the coil voltage is switched off. The LED “excess temperature unit” lights up red.A slope separation avoids simultaneous occurrence of clutch and brake torques.On overexcitation, the coil attraction time is reduced, allowing exact switching and positioning.

ROBA®-takt Circuit Module Type 004.000._

Application

This device is used to start and stop mayr® ROBA®-takt circuit modules and mayr®-clutch brake combinations.It can be used for alternating �4 VDC coil switching, if a �4 VDC power supply is available.

Function

1-sensor operation: – activated – clutch is energised – deactivated – 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 independently of the sensor position when the �4 VDC power supply is switched on.The coil is energised with the �4 VDC power supply.

Slope separation: To avoid simultaneous clutch and braking torques, a slope separation of 0 - 100 ms between clutch and brake can be set, which acts according to the respective rise time and drop-out time of the coils (see switching time table). This adjustment is carried out via the potentiometers Ku = clutch (P�) and Br = brake (P1). The factory default setting is 0 ms.
