A rotating electric machine system includes a rotor. The rotor includes permanent magnets and a rotating shaft. In a rotary electric machine housing, a rotor internal oil passage is formed. A portion of lubricating oil supplied to each of a first bearing and a second bearing is diverted and made to flow through the rotor internal oil passage. The rotor internal oil passage includes direction changeover portions that change a direction through which the lubricating oil flows.
