Rotating electric machine with permanent magnets and magnetic resistance having an improved structure

摘要

The invention concerns a rotating electric machine comprising a stator equipped with armature coils and a rotor mounted rotating inside the stator. The rotor having a rotor part with permanent magnet(s) and a rotor part with magnetic resistance. The rotor is substantially uniform over its axial surface and ahs along its tangential direction a distribution of polar parts with permanent magnet(s) each defining two poles of polarities imposed by magnet(s), ad polar parts with magnetic resistance each defining two poles with free polarities. The invention is applicable to motor vehicle alternators or AC starters.
