Abstract
Electric drive motor, especially for control and regulation purposes, with a pole and coil arrangement for generating a rotating or linearly advancing armature field, which contains pole-forming segments in a plurality of tracks, staggered over time in their excitation phases and geometrically in the direction of movement. The segments are individual segments or are associated with a plurality of coils (without overlapping). Closely stepped tripping. A preferred embodiment of a synchronous motor, such as a hysteresis motor, is described and represented.
