<P>PROBLEM TO BE SOLVED: To appropriately control exothermic heat due to eddy current loss depending on an occurrence factor of eddy current generated in a rotor. <P>SOLUTION: A motor 1 includes a three-phase forward direction field coil group (+U, +V, +W) and a three-phase inverse direction field coil group (-U, -V, -W) made up of coils 74 attached to a plurality of outer peripheral side coil attachment parts 84 and inner peripheral side coil attachment parts 85 in a manner wounded on a circular stator core 73 in a toroidal shape. The three-phase coil groups are arranged in a prescribed phase order in a circumferential direction for each coil group block of each phase. A through-hole 86 penetrating through in the axial direction of the rotational axis 6 of a rotor 11 is provided in a teeth part 83 arranged between the coil groups which are adjacent to each other in the circumferential direction and having different phases to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
