Working Principle

After connecting to the current the force of a magnetic field is used for torque transmission or braking effect.

The armature disk (2) is pulled in axial direction towards the magnet (1) or, respectively, the coupling body (3). The torque transmission or braking torque is transferred by the force of an annular spring (4). The mentioned transfer is backlash-free and wear resistant.

A special treatment of the friction surfaces ensures the nominal torque is achieved without running in procedure or, respectively, after only a few switching processes.

After disconnecting the current the armature (2) is separated from the friction lining by the force of the annular spring (4).
