<p>When multiple sets of multiphase coils are wound around multiple slots provided on a stator, because the coils have different inductances on the entrance side and on the bottom side of the slots, positional control of a rotating electric machine at a high speed may be affected as responsiveness and efficiency deteriorate due to an increased reactive current at a current control circuit. The purpose of the present invention is to provide a rotating electric machine for which inductance differences among multiple coils are minimized. The rotating electric machine is characterized in that multiple sets of in-phase coils are wound by means of multi-turn winding inside same areas of the stator, the coils for the respective phases are respectively divided into multiple coil sides, and the divided coil sides are arranged at different positions in the circumferential direction of the stator while the divided coil sides are separately provided inside and outside respective slots with regard to all of the in-phase coils. Consequently, inductance differences among the coils can be minimized.</p> |
