Summary:PROBLEM TO BE SOLVED: To provide a rotary electric machine which performs effective cooling while reducing loss in a rotor.SOLUTION: A rotary electric machine includes: a stator core 12; and a rotor 16 disposed forming a gap G between itself and the stator core 12. The rotary electric machine controls only a liquid refrigerant supply amount so that a two-phase flow is formed in the gap G by a liquid refrigerant and a gas.SELECTED DRAWING: Figure 1 【課題】ロータでの損失を低減しつつ、効果的な冷却を行うことが可能な回転電機を提供する。【解決手段】ステータコア１２と間隙Ｇを介して配置されるロータ１６と備え、間隙Ｇ内において液冷媒と気体とが二相流となるように液冷媒供給量のみを制御する構成とする。【選択図】図１
