| 摘要 |
<p>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 series of magnets (22N, 22S) with alternating polarities juxtaposed with magnetic parts having magnetic resistance (24a, 24b) respectively associated with said magnets, each assembly of one magnet and one associated magnetic part defining a rotor pole (PP). The invention is characterised in that at least some of said poles have alternately, along a generally tangential direction, a magnet (22S) followed by its magnetic part (24a) and a magnet (22N) preceded by its magnetic part (24b). The invention is particularly applicable to motor vehicle alternators and AC starters.</p> |
