Abstract: An object is to assemble a housing to a mating bracket with high accuracy and to improve the reliability of a rotating electrical machine. A housing of a rotating electrical machine according to the present invention is a housing of a rotating electrical machine that accommodates a stator of the rotating electrical machine and is supported by a support member, the housing including: a first tab that forms a first through-hole through which a first screw passes; and a second tab that forms a second through-hole through which a second screw passes and forms a fitting portion that fits with a position adjustment member, wherein the first tab is formed such that a first facing surface facing the support member of the first tab is farther from the support member than a second facing surface facing the support member of the second tab.

Abstract: The present invention provides a rotary electric machine with improved reliability by suppressing a partial increase in surface pressure generated in a stator using a housing with improved roundness. The rotary electric machine of the present invention has a rotor, a stator, and a tubular housing for fixing the stator from an outer peripheral side. The housing has a flange extending in an outer peripheral direction at an axial end portion of an outer peripheral surface, and the flange has a recess extending in a circumferential direction.

Abstract: Workability during attachment of a sensor element to a rotating electric machine is improved. A semiconductor element functioning as a sensor element for detecting temperatures of concentrated winding coils is inserted between two concentrated winding coils adjacent to each other in a plurality of the concentrated winding coils. One end of a lead wire is connected to the semiconductor element, while the other end of the lead wire is drawn out of a stator. The lead wire has a plurality of bent portions. A hook regulates an extending direction of the lead wire drawn out of the stator such that a bent state of the bent portions of the lead wire is maintained.

Abstract: An object of the present invention is to improve the fixing force of a stator core at low cost. The rotating electric machine includes a stator 300 in which a plurality of stator cores 400 are annularly arranged, a rotor to be arranged on the inner circumferential side of the stator 300, and a housing 500 having a cylindrical shape for fixing each of the plurality of stator cores 400. The stator core 400 has outer circumferential surfaces 410 and 420 arranged to face the inner circumferential surface 510 of the housing 500, and the outer circumferential surfaces 410 and 420 of the stator core 400 are slanted with respect to the inner circumferential surface 510 of the housing 500.

Abstract: A method of manufacturing a rotor of a rotating electrical machine includes a method of manufacturing a rotor of a rotating electrical machine including a magnet and a rotor core forming storage space for storing the magnet. The rotor core forms an opening connected to the storage space. The method includes a first step of covering at least part of the opening with a first jig and a second jig having a non-adhesive resin film, a second step of putting an adhesive into the storage space, a third step of curing the adhesive in a state of being in contact with the non-adhesive resin film to form a plane surface facing an end ring of the rotating electrical machine, and a fourth step of separating the first jig and the second jig from the adhesive.
