Patent attributes
A bistable electromagnetic clutch is provided that includes a first part, a second part and an spring part. The first part includes a yoke with a plurality of iron cores, and an electromagnetic coil on each of the iron cores. The second part includes a moving carrier disc and a magnetic conductive disc that is fixed on a side of the moving carrier disc that is away from the yoke. Several magnets are fixed on the moving carrier disc, and the iron cores and the magnets are provided in a correspondence relation. The spring part is configured to keep the moving carrier disc and the yoke in normally separated positions. Two adjacent electromagnetic coils form a group, two electromagnetic coils in a same group are wound to form a group of windings with identical magnetic polarities, and corresponding two magnets form a group of magnetomotive forces with identical magnetic polarities.
