摘要： A rotor core has a plurality of magnetic steel sheets laminated in an axial direction. Cooling passages extending in an axial direction are formed by aligning openings of the plurality of magnetic steel sheets. The cooling passages have axial direction passages that communicate at one end. A coolant inlet is then formed in one passage, and coolant outlets are formed in the other passages.

摘要： A manufacturing method for a rotary electric machine core includes a lamination step in which a plurality of steel plates is laminated so that a laminated body is configured, a heating step in which the laminated body is heated to a specified target temperature, a pressurization step in which the laminated body is pressed by a pressurization member until a pressure load reaches a target load larger than a specified fastening load in a state where the laminated body is heated to the target temperature, the pressurization member is then made to stand still until the pressure load is constant, and, once the pressure load is constant, the pressurization member is moved away, and a fastening step in which, after the heating and the pressurization are stopped, the steel plates that configure the laminated body are fastened by a fastening part until the fastening load is generated.

摘要： A vehicle electric motor including: a tubular-shaped stator core constituted by electromagnetic steel sheets that are laminated on each other; a rotor disposed inside the stator core so as to be rotated about an axis; and a housing storing therein the tubular-shaped stator core and the rotor, and including a circumferential wall and axially opposite end walls that are opposed to each other in a direction parallel with the axis. The stator core is fixed at one of its axially end portions to one of the axially opposite end walls of the housing. The housing includes a stator-core-inclination restraining portion that protrudes from an inner circumferential surface of the circumferential wall of the housing toward a part of an outer circumferential surface of the stator core, wherein the part is located on a side of the other of the axially end portions of the stator core.

摘要： A cooling structure for a rotating electrical machine includes a rotating electrical machine including a stator and the stator, a temperature sensor, and a first discharge mechanism. A plurality of discharge holes of the first discharge mechanism is disposed in a region excluding an avoidance region. The avoidance region is the same region as an arrangement region that is one of a right side region and a left side region with respect to a vertical line passing an axis of the stator as seen in the axial direction of the stator core, the one of the right side region and the left side region being a region in which the temperature sensor is arranged and the avoidance region is located above a lower end of the temperature sensor in the gravitation direction.

摘要： A rotor 14 includes a shaft having a coolant flow passage and a coolant supply port, a rotor core 24 fixed on the shaft and formed of laminated steel plates, and a magnet set 32 provided in the rotor core 24 to extend along an axial direction thereof. The rotor core 24 has a first flow passage 34 provided near the magnet to extend therealong and a second flow passage 36 that connects the coolant supply port 28 of the shaft 22 and the first flow passage 34, thereby constituting a coolant flow path. The second flow passage 36 is formed by overlapping second slits 37 formed in the respective steel plates at an axially intermediate region A of the rotor core 24, the formed position of the second slit 37 being different for each steel plate combined. The first flow passage 34 and the second flow passage 36 join at the axially intermediate region A of the rotor core 24.
