Abstract

A rotating electric machine comprises a stator having stator salient poles, three-phases windings wound around the stator salient poles, a rotor rotatable held inside the stator, and permanent magnets inserted into the rotor and positioned opposite to the stator salient poles. Three-phase windings, which are concentratively wound around each of the stator salient poles, are 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.
