Abstract: A multi-phase generator without slip rings and brushes and with no windings in its rotor has in its stator an exciting winding and an alternating current winding, mutually displaced half a stator pole pitch. The generator has an additional alternating current winding having a coil pitch about half that one of the original alternating current winding. The additional winding has a coil in each stator pole surface disposed in slots symmetrical in relation to a central slot for the original alternating current winding. For each phase two oppositely disposed coils of each set of alternating current windings, said sets being displaced 90.degree. (mechanical), are connected in series.

Abstract: A multi-phase generator without slip rings and brushes and with no windings in the rotor has its exciting winding and alternating current winding, with a mutual displacement of half a stator pole pitch, disposed in the stator. The generator has an even number of stator poles and a different number of rotor poles.
