ABSTRACT:
Two stator sections are each provided with an annular coil which cooperates with sets of teeth to be magnetized oppositely by the coils. The teeth are arranged in sectors on each section in such a way that the sectors of teeth of one set of teeth lie between those of the other set of teeth. The rotor comprises two rotor sections each having one circularly arranged set of teeth which cooperates with the two sets of teeth of the associated stator section. The two rotor sections are axially spaced by an axially magnetized permanent magnet.
