Abstract:
The invention relates to an electric motor having a permanent magnetic rotor supported in a rotatable fashion around a central axis, a wound stator with a cylindrical stator winding, claw poles, perpendicular in reference to the disc-shaped stator plates and arranged around the central axis, and a tubular return ring connected to the stator plates free from play. The object of the invention is to provide an electric motor, in which the stator is composed from as few parts as possible, with its assembly being simple, its construction being robust, and being provided with an optimum effectiveness, allowing a great freedom of design and space used and thus an economical structure. This object is attained according to the invention in the disc-shaped stator plates being in one piece with the claw poles and being calked to the return ring with the disc-shaped stator plates.
