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 is equipped with a rotating shaft, a bearing for supporting the rotating shaft in a housing, and a rotor internal flow path through which a liquid coolant flows. The rotor internal flow path is formed inside a rotor and extends along an axial direction of the rotating shaft. Groove shaped flow paths are formed in the rotating shaft. The groove shaped flow paths are recessed inwardly in a diametrical direction and extend along the axial direction of the rotating shaft. An inner circumferential surface of the bearing covers the groove shaped flow paths, and thereby constitutes one portion of the rotor internal flow path.

Abstract: A rotating electric machine system is equipped with a rotating electric machine including a rotating shaft and a permanent magnet, and a housing in which the rotating electric machine is accommodated. A bearing is interposed between the housing and the rotating shaft. The bearing is retained by a bearing holder. A pressure applying member is disposed between the bearing holder and the bearing. The pressure applying member applies a pressure to the bearing holder along the axial direction of the rotating shaft.

Abstract: A rotor that constitutes part of a rotating electric machine system includes a rotating shaft. The rotating shaft is supported in a rotating electric machine housing via a first bearing and a second bearing. An oil circulation supply device supplies lubricating oil to the first bearing and the second bearing via a first oil supply line. Further, the oil circulation supply device supplies lubricating oil as a cooling oil via a second oil supply line, with respect to a housing internal oil passage in which a stator of the rotating electric machine system is accommodated. The first oil supply line and the second oil supply line are separate lines.

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.

Abstract: For a rotary electric machine housing, a cooling jacket and compressed air flow passages are formed on an outer circumferential side of the cooling jacket. On an outer side wall of the rotary electric machine housing, a terminal casing is formed and electric terminal portions are accommodated in the terminal casing. Air bleed ports are formed in a shroud case of a gas turbine engine. Compressed air that is compressed by a compressor wheel flows into the air bleed ports. The compressed air that has passed through the air bleed ports flows through air bleed passages formed in an engine housing and the compressed air flow passages. Then, the compressed air reaches the terminal casing.
