Title: BUS BAR UNIT AND MOTOR
Abstract:
A bus bar unit has: a bus bar holder; and a U-phase bus bar group, a V-phase bus bar group, and a W-phase bus bar group. The U-phase bus bar group, the V-phase bus bar group, and the W-phase bus bar group each have: a first layer bus bar positioned on one side of the bus bar holder in the axial direction and extending along a plane orthogonal to the axial direction; a second layer bus bar positioned on one side of the first layer bus bar in the axial direction and extending along a plane orthogonal to the axial direction; and an external connection terminal connected to the first layer bus bar and the second layer bus bar and extending from the first layer bus bar and the second layer bus bar toward one side in the axial direction. In the U-phase bus bar group, the V-phase bus bar group, and the W-phase bus bar group, the first layer bus bar and the second layer bus bar each extend from the external connection terminal connected thereto toward mutually opposite sides in the circumferential direction.
