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 100 includes: a stator; a rotor 16 disposed forming a gap G between itself and the stator; and a refrigerant supply device which intermittently supplies a liquid refrigerant to the gap to form a gas-liquid two-phase flow formed by the 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】ステータと、ステータに対して間隙（ギャップ）Ｇを介して配置されたロータ１６と、を備え、間隙（ギャップ）に対して間欠的に液冷媒を供給することによって、液冷媒と気体との気液二相流を形成する冷媒供給装置を備える回転電機１００とする。【選択図】図１
