Holding brake
Application
A single–surface brake can be mounted on the drive end to hold the motor shaft
at standstill without any play.
Design
The drive end bearing end shield is supplied with special outer bearing cover
design to mount the solenoid assembly (brake assembly). Customers can bolt–
on the solenoid assembly. The brake armature disk should be bolted to the
drive–out element (pulley belt or similar).
The brakes have no slip rings and are maintenance–free. Both of the friction
surfaces are metal.

Mode of operation
The brake operates according to the working principle, i.e. the brake is released
when it is in a no–current condition.
The brake may only be applied when the motor is at a standstill.
The holding brake must be released (no–current condition) when the gearbox
ratio is changed and when the motor is operational. After the brake has been
released, there is no residual braking torque.
After mounting to the motor, the brake should be checked to ensure that it is
functioning correctly.
