Abstract:
PCT No. PCT/FR96/01904 Sec. 371 Date Oct. 2, 1997 Sec. 102(e) Date Oct. 2, 1997 PCT Filed Nov. 29, 1996 PCT Pub. No. WO97/23943 PCT Pub. Date Jul. 3, 1997A two-phase motor formed by a stator part excited by electric coils and a magnetized rotor. The rotor has N pairs of poles which are radially magnetized in alternate directions, N being equal to 3 or 5. The stator part has at least two W-shaped circuits comprising each an electric coil surrounding the central leg. The "W" circuits are so arranged that when one of the central legs faces a magnetic transition, the other central leg faces a magnetic pole. The polar opening outs of the legs of a "W" circuit are angularly spaced by pi /4. The polar opening outs of the central legs of the two "W" circuits belonging to different phases are angularly spaced apart by an angle which is substantially equal to pi /2+/-k. pi /N, where N is the number of pairs of magnetic poles, that is 3 or 5, and k is equal to 0, 1 or 2.
