| 摘要 |
The invention concerns a rotating electric machine comprising a stator (10) equipped with armature coils (18) and a rotor (20) mounted rotating inside the stator, the rotor having a rotor part (210) with permanent magnet(s) and a rotor part with magnetic resistance (220). The invention is characterised in that the rotor is substantially uniform over its axial surface and has along its tangential direction a distribution of polar parts (212, 214a, 214b) with permanent magnet(s) (214a, 214b) each defining two poles (PSA, PNA) of polarities imposed by magnet(s), and polar parts with magnetic resistance (222) each defining two poles (PR1, PR2) with free polarities. The invention is applicable in particular to motor vehicle alternators or AC starters.
