Electromagnetic brakes & clutches

Electromagnetic clutches and brakes of Kendrion (Aerzen) GmbH are easy to install and integrate into the machinery concept/layout with no setting up or running in. Kendrion offers a combination fitted on a hollow shaft for applications where clutches and brakes work together. The units are based on the successful magneta components. They are fitted on a through shaft. The unit is fixed using simply two screws and is ready for operation then. Electromagnetic clutches and electromagnetic brakes from Kenrion (Aerzen) GmbH transmit the drive torque and braking torque frictionally in dry running conditions. If a DC current is applied, the torque is transferred without backlash. Residual torque free ventilation in a de-energised state is ensured by the prestressed annular spring of the armature section. The clutches and brakes are suitable for every mounting position and require almost no maintenance.

The Active Brake Line includes DC single-disc brakes, in which the action of force of an electromagnetic field (electromagnetically closing) is used to generate the braking force. The Active Brake Line is characterized by a secure, residual moment-free lifting in any position, and by a backlash-free transfer of the braking torque. Throughout their complete service life, they require little or no maintenance.

The main characteristic of the magnetic particle clutch is the possibility to smoothly change the torque depending on the field voltage. To transmit the torque from the external to the internal rotor, specifically alloyed and highly abrasion-resistant iron particles are inserted into the particle gap. Depending on the electromagnetic field, these fine iron particles build magnetic chains and thus transmit the torque. The power of the field determines the stability of the particle chains and also the transmittable torque.

The PM Line includes permanent magnet brakes in which the braking force is generated by a permanent magnetic field. The brake thus works in a de-energized condition and fulfill the following functions: Holding, positioning and emergency stop. The neutralization of the braking force is effected by the counteracting electric field, granting a high degree of security, even in the case of power failure. Permanent magnet brakes are characterized by a secure, residual-moment-free lifting in any position, and by a backlash-free transfer of the braking torque. Therefore, they are ideal for servo motor applications.
