| 摘要 |
The invention concerns a rotating electrical machine with double excitation mounted on a shaft comprising a rotor (82) whereof the magnetic circuit carries at least one excitation element and a stator (90) whereof the magnetic circuit carries a stator coil. The invention is characterised in that said at least one excitation element includes at least a ring-shaped magnet (87) associated with at least two disks (83a, 83b) each provided with radial teeth evenly distributed at their periphery and at least a ring-shaped part (86) provided with slots in each of which is engaged contactless, one tooth of at least one toothed disk, and the stator magnetic circuit comprises an even number, not less than two, of ring-shaped elements of magnetic circuit (91) at least an excitation stator coil (93, 95) being arranged between at least two neighbouring elements among said magnetic circuit elements.
