Abstract:
1. A bus ring attached to a stator having a plurality of stator teeth aligned in a circumferential direction and an end face thereof turned toward an axial direction, which is the direction of an axis about which a rotary electrical machine rotates a drive shaft, the bus ring being attached to the stator along the end face, the bus ring being made by curving a plurality of conductive wires in an arc shape with a diameter smaller than that of the stator, wherein the plurality of conductive wires are respectively aligned in the axial direction, wherein extending portions bent so as to respectively extend in a radial direction are formed at the plurality of conductive wires and respective bent portions are formed in the conductive wires so as to be interposed between the extending portions, and wherein staple-shaped bent portions protruding in the axial direction are formed at the plurality of conductive wires from the extending portions and a winding wound around each of the plurality of stator teeth is connected to the bent portions.
