PROBLEM TO BE SOLVED: To provide a rotary electric machine system which can suppress variation of output torque of the rotary electric machine at the occurrence time of abnormality of the rotary electric machine and improve accuracy of abnormality determination of the rotary electric machine.SOLUTION: A rotary electric machine system comprises: a motor 10 including coil groups 11, 12; inverter units 21, 22; sensors 26, 28 which detects prescribed state quantity used for controlling power output of the first inverter unit 21; and a controller 41 which determines whether abnormality occurs in at least one of the first coil group 11, a first electrical power system including the first inverter unit 21, and the sensors 26, 28, adjusts electric power supplied to the first coil group 11 according to a kind of the abnormality on condition that occurrence of the abnormality is determined, increases current flowing in the second coil group 12 and determines whether abnormality occurs again when output torque generated by flowing current in the first coil group 11 is decreased, and prohibits power supply of the first inverter unit 21 on condition that occurrence of the abnormality is determined.SELECTED DRAWING: Figure 2

    【課題】回転電機の異常発生時に回転電機の出力トルクが変動することを抑制するとともに、回転電機の異常判定の精度を向上させる。【解決手段】巻線群11,12を含むモータ10と、インバータ部21,22と、第1インバータ部21の電力出力の制御に用いられる所定の状態量を検出するセンサ26,28と、第1巻線群11、第1インバータ部21を含む第1電源システム、及び、センサ26,28の少なくともいずれかに異常が生じているか否かを判定し、異常が生じていると判定されたことを条件として、異常の種類に応じて第1巻線群11に供給される電力を調整し、第1巻線群11に電流が流れることで生じる出力トルクが減少する場合に、第2巻線群12に流れる電流を増加させるとともに、異常が生じているか否かを再び判定し、異常が生じていると判定されたことを条件として、第1インバータ部21の電力供給を禁止する制御部41と、を備える。【選択図】 図2
