摘要： A detection part of a temperature detection element is mounted to ends of drawn portions which are further protruded in the axial direction than coil end portions. The detection part and the ends of the drawn portions provided with the detection part are covered with a covering member. The ends of the drawn portions provided with the detection part and covered with the covering member are inserted into a through hole of a wall member which is disposed so as to axially face an axial end face of a stator core. In this case, the detection part is located at a position deeper (on the rear side) than a position of a stator core side opening of the through hole.

摘要： A motor control device includes coil temperature detection means, cooling oil temperature detection means, and a control unit. The control unit implements a coil protection torque restriction and a cooling oil protection torque restriction. The control unit makes it easier for the coil protection torque restriction to be preferentially implemented in a low rotation operating region in which a motor operates at a low rotation speed equal to or lower than a predetermined value, and makes it easier for the cooling oil protection torque restriction to be preferentially implemented in a high rotation operating region in which the motor operates at a higher rotation speed than in the low rotation operating region.

摘要： A rotating electrical machine has a housing, a stator having a stator core and a rotor having a rotor core and rotor side plates rotatably supported by the housing. The rotor core is arranged to have a gap between the end surfaces of the rotor core and the stator. Oil containers are arranged on at least one surface of the rotor side plate. Each oil container has a scoop-up part and an exhaust outlet formed on end sections thereof. When the rotor is rotating, the scoop-up part scoops up an oil stored in the housing, the oil and inside air are compressed in the oil container, and the exhaust outlet exhausts the oil and compressed air to the coil end of the stator. The housing stores the oil at a lowermost side thereof so that the scoop-up part and the exhaust outlet are immersed in the oil.

摘要： A motor generator includes three types of cooling through-holes. The cooling through-holes are three types of holes passing through the coil end portions in the radial direction and having different flow capacities that allow different amounts of liquid refrigerant to flow. Holes with larger flow capacities allow larger amounts of liquid refrigerant to flow therethrough. In the motor generator, the three types of cooling through-holes are arranged as appropriate according to the temperature increase characteristics of the coil end portions. Consequently, in the motor generator, an appropriate amount of liquid refrigerant can be delivered to each part of the coil end portions according to the difference in temperature increase rate.

摘要： A device for driving a vehicle including an engine that serves as a power source of the vehicle, and a transmission that is connected to the engine, the engine and the transmission being arranged transversely such that an axial direction of an output shaft of the engine accords with a right-left direction of the vehicle includes a motor generator (MG) that serves as a power source of the vehicle, and a speed reducer that is connected to the MG. The MG and at least a part of the speed reducer are arranged outside of an engine compartment that accommodates the engine and the transmission. An output shaft of the speed reducer is connected to a power transmission system, which transmits power of an output shaft of the transmission to a drive shaft of a vehicle wheel to be capable of transmitting its power to the power transmission system.

摘要： A rotating electric machine includes a rotating shaft, a rotor fixed on the rotating shaft, a stator, a housing, a liquid coolant and a flow direction regulating member. The stator is arranged so that a radially inner peripheral surface of the stator radially faces a radially outer peripheral surface of the rotor through an annular gap formed therebetween. The housing covers both axial ends of the stator and rotatably supports the rotating shaft. The liquid coolant is provided in an internal space formed in the housing to flow into at least part of the annular gap formed between the radially inner peripheral surface of the stator and the radially outer peripheral surface of the rotor. The flow direction regulating member axially faces an axial end face of the rotor through an axial gap formed therebetween and regulates the flow direction of the coolant by means of the axial gap.

摘要： An electric rotary machine includes a stator, which Is fixed to a housing, composed of a stator core having a coil end protruding at an end face of the stator core, a rotor core formed by laminating core sheets, and a rotor having a pair of rotor side-plates sandwiching both end faces of the rotor core. The rotor core is rotatably supported in the housing facing an inner peripheral surface of the stator with a gap between the rotor core and the stator. Either one or both of the rotor side-plates has a concave surface in an outer surface of the side-plate that does not abut the rotor core. An axial distance from the end face of the rotor core to the concave surface increases from an inner diameter side to an outer diameter side.
