ROBA®-quick is an electromagnetic pole face brake actuated by industrial current. A magnetic field is formed by applying a DC voltage to the solenoid coil. This attracts the armature disk to the brake coil carrier with friction lining. The braking torque runs from the coil carrier via the friction lining, armature disk and diaphragm transmission spring to the flange and shaft. In the de-energised state, the diaphragm transmission spring pulls the armature disk back to the flange. This releases the brake and the shaft can run freely.
