Rotary electric machine system and vehicle

Abstract:

A rotary electric machine system includes a rotary electric machine unit, a temperature adjustment unit, and a control unit. The rotary electric machine unit includes a rotary electric machine and a temperature detection unit. The rotary electric machine includes a stator core around which a coil is wound, and a rotor having a magnet. The temperature adjustment unit increases the temperature of the stator core. When a rotational speed of the rotary electric machine is in a predetermined high-speed rotation state, in a case in which the temperature detected by the temperature detection unit is less than a predetermined value, the control unit controls the temperature control unit to increase the temperature of the rotary electric machine.
