Abstract: 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.

Abstract: A rotating electric machine system is equipped with a rotor including permanent magnets and a rotating shaft. The rotating shaft is supported in a rotating electric machine housing via a first bearing and a second bearing. 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 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.

Abstract: In a rotating electric machine system, a rotating shaft retaining permanent magnets includes an oil guiding member. An annular gap is formed between the rotating shaft and the oil guiding member. Lubricating oil that has flowed through a second oil supply passage formed in a rotating electric machine housing is supplied to an annular gap. The annular gap communicates with a rotor internal oil passage.

Abstract: A rotating electric machine system includes a rotor and a stator. A rotor internal oil passage is formed in the interior of the rotor. The rotor is cooled by a first cooling oil serving as a lubricating oil that flows through a rotor internal oil passage. A housing internal oil passage is formed in a rotating electric machine housing. The stator is cooled by a second cooling oil serving as a lubricating oil that flows through the housing internal oil passage. A route by which the first cooling oil is supplied to the rotor internal oil passage, and a route by which the second cooling oil is supplied to the housing internal oil passage are different from each other.
