Page 18: Functional Description
PrODUcT DEScrIPTION 2.6 functional description The braking force is generated in de-energised state by pressure springs which press the armature and the lining against the friction surfaces. The lining is twist-proof but can be axially moved while connected to the shaft. After applying the rated voltage, the coil inside the magnet creates a magnetic field which attracts the armature against the spring force. -
