Abstract:
A bus bar unit for supplying power to coils (16) of multiple phases, said bus bar unit being equipped with: bus bars (47U, 47V, 47W) for each phase, said bus bars being connected to the end of the coils where winding begins; and neutral-point bus bars (81) connected to the end of the coils where winding ends. The neutral-point bus bars (81) are formed by bending a long plate-like member such that the width direction of the plate-like member aligns with the diameter direction of the bus bar unit. The neutral-point bus bars are equipped with multiple bus bar pieces (82), and connecting sections (83) which connect adjacent bus bar pieces (82, 82). The width of deforming parts (85) of the connecting sections (83) is less than the width of the bus bar pieces (82).
