ABSTRACT:
A rotating electric machine comprises a stator having stator salient poles, three-phase windings wound around said stator salient poles, a rotor rotatable held inside the said stator, and permanent magnets inserted into said rotor and positioned opposite to said stator salient poles. The three-phase windings are concentratively wound around each of the stator salient poles, with windings of each phase wound around more than one stator salient pole. The windings of each phase have a phase difference of voltage between at least one of the windings and the other.
