Abstract: A motor shaft includes a first shaft portion, a second shaft portion, a hollow intermediate shaft portion, a first connecting portion connecting the first shaft portion to the intermediate shaft portion, and a second connecting portion connecting the second shaft portion to the intermediate shaft portion. The intermediate shaft portion has an outer diameter larger than outer diameters of the first and second shaft portions and supports a rotor core on an outer circumference thereof. The motor shaft is configured to include a first member integrally formed to include the first shaft portion and the first connecting portion and a second member integrally formed to include the second shaft portion and the second connecting portion. At least one of the first connecting portion and the second connecting portion is provided with an outer flange that protrudes radially outward from an outer circumferential surface of the intermediate shaft portion.

Abstract: The present invention realizes an improvement in the moldability of a resin portion that is injection-molded to an annular stator. A plurality of collar portions formed integrally with a peripheral edge of the insulating cover so as to project beyond the outer diameter of the annular stator, and a resin pin molded integrally with one of the collar portions, wherein a collar resin portion of the collar portion and a resin pin resin portion of the resin pin are integrated with each other when seen from above, and a first outer diameter of the collar resin portion is larger than a second outer diameter of the resin pin resin portion.

Abstract: A rotating electric machine unit includes a first rotating electric machine, a second rotating electric machine, and a case having a case main body and a case cover. The first rotating electric machine and the second rotating electric machine each includes a stator core, a multi-phase coil attached to the stator core, and a power distribution member connecting the multi-phase coil. The case cover includes a first bulging portion facing the coil end of the first rotating electric machine, and a third bulging portion facing the coil end of the second rotating electric machine. The third bulging portion is positioned closer to a case main body side than the first bulging portion, and at least a part of a wiring connected to the first rotating electric machine is arranged along a surface of the third bulging portion.

Abstract: A rotating electrical machine unit includes: a rotating electrical machine; a resolver which includes a resolver rotor and a resolver stator; and a case which accommodates the rotating electrical machine and the resolver. The resolver stator includes: a stator portion; a telegraph connector portion; and a first positioning portion including a knock portion protruding to one side. The telegraph connector portion includes a second positioning portion having a fitting portion having a sealing member on an outer peripheral surface. The resolver stator is attached to the case by being positioned with the knock portion of the first positioning portion being fixed to a knock fixing portion of the case and the fitting portion of the second positioning portion being fitted into a mounting hole of the case.

Abstract: There is provided a resolver rotor in a resolver provided to a rotating electrical machine. The resolver rotor is formed from an annular body. A phase determination hole for setting a relative position to a shaft of a motor is provided at a near outer peripheral portion of the resolver rotor. A virtual circle is set which comes into contact with a section of the phase determination hole at a proximal end to an inside diameter of the resolver rotor, and has a center point coincident with the center of the resolver rotor. A pair of hole portions are arranged at portions extending from the virtual circle to an outside diameter side of the resolver rotor while taking in the virtual circle.
