| 摘要 |
The invention concerns an AC rotary electric machine, such as a motor-generator comprising: a internal rotor (7) peripherally (6) made of mild steel and provided with permanent magnets (3) with radial magnetisation distributed with alternating N and S poles, said magnets (3) being made of a high induction material; and an annular stator (1) coaxially enclosing the rotor (7) made of mild steel, and having internally radial cores (2) each bearing: an emitter coil (4) arranged opposite to and in the proximity of the rotor and a receiver coil (5) arranged radially rearwards of the receiver coil and magnetically coupled therewith; the emitter coils (4) having their winding direction alternately inverted and being all connected (18) to one another in series, between two terminals (9) supplying electric power to the machine; the receiver coils (5) having all their respective windings in the same direction and being connected (19) to one another in series, between two terminals (10) between which occurs a voltage when the machine is operating.
