To enable a relatively high heat quantity to be generated in the stop state of a movable body by using a single rotary electric machine.SOLUTION: A drive device for a rotary electric machine which controls a wound-field type rotary electric machine includes: an inverter circuit which supplies multi-phase AC power to a stator coil wound around a stator core; a full-bridge circuit which supplies power to a rotor coil wound around a rotor core; and a processing device which controls the inverter circuit and the full-bridge circuit. In a stopped state of the movable body, the processing device is configured to, while supplying the stator coil with the multi-phase AC power, supply the rotor coil with AC power that reduces or eliminates reluctance torque generated in the rotor core due to the multi-phase AC power.SELECTED DRAWING: Figure 3B

    【課題】1つの回転電機を利用して、移動体の停止状態において比較的高い発熱量を発生可能とする。【解決手段】巻線界磁型の回転電機を制御する回転電機用駆動装置であって、ステータコアに巻回されたステータコイルに複数相の交流電力を供給するインバータ回路と、ロータコアに巻回されたロータコイルに電力を供給するフルブリッジ回路と、これらを制御する処理装置とを備え、処理装置は、移動体の停止状態において、ステータコイルに複数相の交流電力を供給しつつ、複数相の交流電力に起因してロータコアに生じるリラクタンストルクを低減又は無くすような交流電力をロータコイルに供給する、回転電機用駆動装置が開示される。【選択図】図3B
