Abstract
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.
