摘要： A rotating electric machine system (10) is equipped with a rotor (34) including permanent magnets (72) and a rotating shaft (40). The rotating shaft is supported in a rotating electric machine housing (14) via a first bearing (74) and a second bearing (84). A first oil supply passage is formed in the rotating electric machine housing for supplying lubricating oil to the first bearing and the second bearing. Further, a rotor internal oil passage (354) is formed in the interior of the rotor. A portion of the lubricating oil is diverted away from the first oil supply passage, and is supplied to the rotor internal oil passage.
