摘要： A rotor core of a rotating electric machine includes a cooling passage. The cooling passage includes an upstream end that opens in a first end surface of the rotor core and a downstream end that opens in a second end surface of the rotor core. The rotating electric machine is further equipped with a rectifying structure for converting the flow direction of gas an axial direction and a circumferential direction of the rotor. The rectifying structure is fixed to a non-rotating portion in a casing so as to face a rotor in an axial direction.

摘要： 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.

摘要： 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.

摘要： A combined power system includes a rotary electric machine housing in which a rotating shaft of a rotary electric machine is rotatably supported. For the 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. Compressed air is supplied to the terminal casing. An electrical current converter formed on the outer side wall of the rotary electric machine housing is cooled by the cooling jacket.

摘要： 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.

摘要： A rotor of a rotary electric machine includes a rotor core. The rotor core is a stacked body in which a plurality of electromagnetic steel sheets are stacked. The electromagnetic steel sheet includes an inner annular portion and an outer annular portion. A first insertion hole into which a rotating shaft is inserted is formed in the inner annular portion. A rotor inner diameter is defined as twice a distance from a center of the first insertion hole to an inner circumferential edge of the inner annular portion. A rotor outer diameter is defined as twice a distance from the center of the first insertion hole to an outer circumferential edge of the outer annular portion. A ratio of the rotor inner diameter to the rotor outer diameter is within a range of 1:1.5 to 1:3.5.
