To provide a cooling system of a rotary electric machine which enables reduction of costs and cools a rotary electric machine efficiently to optimize a workload of a pump without mounting a mechanism needing a wide space.SOLUTION: A cooling system 29 of an embodiment includes: a rotary electric machine 1 having a case 2 in which a first refrigerant flows; a pump 30 which is driven by rotational driving force of the rotary electric machine 1 and pumps a second refrigerant; a first passage 31 which extends from the pump 30 to the rotary electric machine 1 and guides the second refrigerant to the rotary electric machine 1; a second passage 32 which branches from the first passage 31 and guides the second refrigerant to the pump 30; and a solenoid 50 which adjusts flow of the second refrigerant to the first passage 31 and the second passage 32.SELECTED DRAWING: Figure 1

    【課題】コストを抑え且つ広いスペースを必要とする機構を搭載することなく、回転電機を効率的に冷却し、ポンプの仕事量を最適化する。【解決手段】実施形態の冷却システム29は、第一冷媒が通流されるケース2を有する回転電機1と、回転電機1の回転駆動力により駆動し、第二冷媒を圧送するポンプ30と、ポンプ30から回転電機1まで延びて第二冷媒を回転電機1へ案内する第一流路31と、第一流路31から分岐し、第二冷媒をポンプ30へ案内する第二流路32と、第一流路31と第二流路32とへの第二冷媒の流れを調整するソレノイド50と、を備える。【選択図】図1
