Title: BUS BAR UNIT AND MOTOR COMPRISING SAID BUS BAR UNIT
Abstract:
A bus bar unit in which an inside bus bar and an outside bus bar, which extend in the circumferential direction with respect to the central axis of a motor and are connected to a coil of a stator, are held by a bus bar holder of a resin-molded article, the outside bus bar being placed further radially outward than the inside bus bar. The bus bar holder has: a first inside support wall that supports the outer circumferential surface of the inside bus bar; a first outside support wall that supports the inner circumferential surface of the outside bus bar; a plurality of openings through which pass a leader line of the coil, the openings opening along the circumferential direction of the first inside support wall and/or the first outside support wall; and a connecting rib that connects the first inside support wall and the first outside support wall, the connecting rib extending in the radial direction between adjacent openings in the circumferential direction.
