ROTARY ELECTRIC MACHINE

To provide a rotary electric machine in which a stator and a rotor can be efficiently cooled.SOLUTION: From a stator-side injection hole 107 and rotor-side injection holes 108, 110 formed in a liquid pass 100 that is for a cooling liquid CL and that is formed inside the bottom surface side of a motor cover 20, the cooling liquid CL is simultaneously injected toward a coil 34 of a stator 36 and an inner space of a bottomed cylindrical portion 30 of a rotary shaft 14 to which a rotor 44 is externally fitted. Inside the rotor 44, liquid passes 121, 122, 123, 116 that are connected with suction ports 111, 112, 113 formed in an inner surface of the bottomed cylindrical portion 30 and that are extended to discharge ports 131, 132 in end plates 48, 50, are formed.SELECTED DRAWING: Figure 2 【課題】ステータとロータを効率よく冷却することを可能とする回転電機を提供する。【解決手段】モータカバー２０の底面側内部に形成された冷却液体ＣＬの液路１００に形成したステータ側噴射孔１０７とロータ側噴射孔１０８、１１０からステータ３６のコイル３４と、ロータ４４が外嵌する回転軸１４の有底円筒部３０の内部空間とに向けて同時に冷却液体ＣＬを噴射する。ロータ４４の内部には、前記有底円筒部３０の内側面に形成された吸入孔１１１、１１２、１１３に連通し、エンドプレート４８、５０の排出孔１３１、１３２まで延びる液路１２１、１２２、１２３、１１６が形成されている。【選択図】図２
