ABSTRACT:
A rotatory electromotor having a stator with stator poles and a rotor with rotor poles, permanent magnets being provided for the stator poles or for the rotor poles and electromagnets for the poles not provided with the permanent magnets, electronic switching means being provided for switching electromagnets in accordance with the relative positions of the electromagnets and permanent magnets in each case, and the permanent magnets and the electromagnets being arranged in such a way that only some of the electromagnets of the electromotor can be simultaneously switched in each case. Several adjacent electromagnets form a group of electromagnets belonging to one phase, this group cooperating with a number of permanent magnets located opposite, and adjacent groups of electromagnets belong to different phases.
