Electromagnetic brake has maximum electromagnetic coil arrangement force less than spring force after wear gap corresponding to initial air gap plus maximum permissible wear

摘要

The device (2) has at least one brake disc (4), an armature disc (5) pressed against the brake disc by a coil spring arrangement (8) and an electromagnetic coil unit (6) for raising the armature disc against the force of the spring arrangement. The maximum force of the electromagnetic coil unit is smaller than the spring force of the spring arrangement after a wear gap corresponding to the initial air gap added to the maximum permissible wear.
