Design
The drive shaft bearing end shield is supplied with an external bearing cover (special
version) as a fastening part for the magnet block (brake pad). The magnet block can be
attached by the customer. The armature disk of the brake is screwed on to the output
element (belt pulley or similar). The brakes are brushless and maintenance free. Both
braking surfaces are made of metal.

Mode of operation
The brake works according to the open-circuit principle, i.e. the brake is open when de-
energized.
Only turn brakes on with motor at standstill.
The holding brake must be released when switching the gearbox and when the motor is
running (no current). There is no remaining torque after release.
The holding brake is only designed for a limited number of emergency braking operations. It
is not permissible to use the brake as operating brake.
After mounting the motor, the brake must be checked for proper function.
