ABSTRACT:
The invention relates to an electric motor comprising a permanent magnet rotor, which is supported rotationally about a central axis, a wound stator having a cylinder ring-shaped stator winding, claw poles, which are disposed perpendicularly to ring disc-shaped stator plates and around the central axis, and a cylinder jacket-shaped yoke ring, the length of the claw poles in the axially parallel direction being clearly greater than half the inner diameter of the stator. It is the object of the invention to provide an electric motor, in which the stator is composed of the least number of components, requires simple assembly and has a robust structure and optimum efficiency, thereby enabling greater design flexibility, usability of installation space and thus an economic construction. This objective is solved according to the invention in that the magnetically conductive part of the stator comprises a cylinder jacket-shaped yoke ring and two ring disc-shaped stator plates, the stator plates are each designed as a single piece with a plurality of claw poles and the ring disc-shaped stator plates comprise ends, which are connected to one another.
