US Patent 11368073 Rotating electrical machine

In a rotating electrical machine, of both ends of a stator winding of each phase, an end portion on a neutral point side is a first end portion, and an end portion on a connection point side of an upper arm switch and a lower arm switch of an inverter is a second end portion. The rotating electrical machine includes a neutral-point bus bar that electrically and mechanically connects the first end portions of the phases to one another. The first end portion and the second end portion of each phase is arranged in an end portion on a same side in an axial direction of a stator. The neutral-point bus bar and the second end portion of each phase are mechanically connected with an insulating sheet therebetween.
