Abstract
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.
Claims21
A rotary electrical machine, in particular an alternator or combined alternator/starter motor for automobile vehicles, comprising a stator equipped with stator windings and a rotor mounted to rotate inside the stator, the rotor having a permanent magnet rotor part and a variable reluctance rotor part, wherein the rotor is substantially uniform throughout its axial length and has in its tangential direction a distribution of permanent magnet pole parts with a permanent magnet(s) each defining two poles whose polarity is imposed by the magnet(s) and variable reluctance pole parts each defining two poles whose polarity is not imposed.
