Abstract
An electric power collection and distribution ring includes a plurality of annular bus rings for collecting and distributing power to windings of a stator, the windings being covered with an insulation cover and the stator being formed by winding the windings around a plurality of teeth arranged in a circular pattern. The bus ring is formed by annularly coupling a plurality of arc-shaped conductive members each including terminal portions at both circumferential end portions, the terminal portions being welded to each other together with an end portion of the winding. The terminal portion includes a first contact surface coming into contact with the end portion of the winding at the time of the welding and a second contact surface to be a contact point between the terminal portions.
