摘要： A rotating electric machine includes a neutral busbar and a temperature sensor. The neutral busbar has a main body and a bent part that retains the temperature sensor therein. The main body has first and second parts each of which has one or more connection terminals formed therein. The bent part is formed between a circumferential end portion of the first part and a circumferential end portion of the second part. In the first part, there is formed, between the circumferential end portion of the first part and a closest connection terminal formed in the first part to the bent part, a first extending portion that extends axially or radially. Similarly, in the second part, there is formed, between the circumferential end portion of the second part and a closest connection terminal formed in the second part to the bent part, a second extending portion that extends axially or radially.

摘要： A rotating electric machine includes an armature and a busbar unit. The armature includes an annular armature core and a multi-phase armature coil wound on the armature core. The busbar unit is configured to connect winding end portions of the armature coil which are arranged apart from one another in a circumferential direction of the armature. Moreover, the busbar unit is fixed to a back yoke of the armature core by a plurality of pins.

摘要： In an armature, a busbar unit includes at least first-, second-, and third-phase busbars electrically connected to respective first-, second-, and third-phase armature windings. The first-phase busbar serves as a lowermost busbar in the axial direction, the second-phase busbar serves as an intermediate busbar stacked over the lowermost busbar in the axial direction, and the third-phase busbar serves as an uppermost busbar stacked over the intermediate busbar in the axial direction. A resin member of the busbar unit covers the lowermost busbar, intermediate busbar, and uppermost busbar stacked in the axial direction, so that the lowermost busbar, intermediate busbar, and uppermost busbar are integrated to constitute a busbar stack. A protrusion member is mounted to the intermediate busbar and protruding radially outward from the intermediate busbar. At least part of the protrusion member is located to be nonoverlapped with the uppermost busbar and the lowermost busbar.
