Electromagnetic clutch device for e.g. gear motor, has control lever, axle, cam and guide constituting coupling mechanism for maintaining clutch device in coupling position during disconnection of supply to electromagnetic coupling unit

摘要

The device has a movable clutch plate (2) displaced towards a fixed clutch plate (1) under the action of an electromagnetic coupling unit for coupling the movable plate with the fixed plate. A control lever (3), an axle (5) integrated to the lever, a cam (4) and a guide constitute a mechanical coupling mechanism for maintaining the device in a coupling position during the disconnection of supply to the electromagnetic coupling unit.
