Zusammenfassung:	To provide a rotary electric machine system in which a rotor is efficiently cooled by lubricating oil.SOLUTION: A rotary electric machine system includes a rotor having a permanent magnet and a rotary shaft 40. The rotary shaft is supported by a rotary electric machine housing via a first bearing 74 and a second bearing 84. A first oil supply passage for supplying the lubricating oil to the first bearing and the second bearing is formed in the rotary electric machine housing. Further, an in-rotor oil passage is formed inside the rotor. A part of the lubricating oil is diverted from the first oil supply passage and supplied to the in-rotor oil passage.SELECTED DRAWING: Figure 12 【課題】ロータが潤滑油によって効率よく冷却される回転電機システムを提供する。【解決手段】回転電機システムは、永久磁石及び回転シャフト４０を有するロータを備える。回転シャフトは、第１ベアリング７４及び第２ベアリング８４を介して回転電機ハウジングに支持される。回転電機ハウジングには、潤滑油を第１ベアリング及び第２ベアリングに供給する第１油供給路が形成される。また、ロータの内部には、ロータ内油路が形成される。潤滑油の一部は第１油供給路から分流され、ロータ内油路に供給される。【選択図】図１２
