摘要： The vehicle drive system includes: a motor having a stator and a rotor; and a battery. The stator has primary conductors, the rotor has secondary conductors, and the battery has battery modules. A motor ECU and a battery ECU are provided. The motor ECU can change the number of poles of the motor by increasing/reducing the number of primary conductor groups, in each of which a current flows in the same direction and the primary conductors are continuously aligned in a circumferential direction. The battery ECU can change a connection mode of battery module pairs, which are electrically connected to each other, between in series and in parallel. The ECU, the motor ECU, and the battery ECU are configured to initiate changing the number of the poles and changing the connection mode of the battery module pairs at different timings from each other.

摘要： In a rotary electric machine, a rotor, and a stator. The stator includes slots provided in a circumferential direction thereof, and stator windings wound in the slots. The stator windings include n groups of three-phase windings, where n is a power of 2. The slots include first slots each accommodating portions of same-group and same-phase windings in the n groups of three-phase windings. The energizing directions of the same-group and same-phase windings are identical to each other. The second slots each accommodate different-group and same-phase windings in the n groups of three-phase windings. The first slots and the second slots are arranged in the stator at predetermined intervals in a circumferential direction of the stator, and the three-phase windings of each group are wound around the stator with regular intervals therebetween.
