Kind Code:
A
Abstract:
To provide a motor and a drive device capable of combining strength of a rib with a soldering space of a metal electrical connection terminal of a bus bar.SOLUTION: A motor comprises a bus bar assembly that comprises a resin bus bar holder and a metal electrical connection terminal 1121 molded integrally with the bus bar holder. The bus bar holder comprises: an outer peripheral wall 1111; a bearing supporting part 1112 located radially inside the outer peripheral wall 1111; and a plurality of radial coupling parts coupling between the outer peripheral wall 1111 and the bearing supporting part 1112 in a radial direction. The plurality of radial coupling parts comprises: a first radial coupling part 1113-1 integrally molded with at least a part of the metal electrical connection terminal 1121; and a second radial coupling part 1113-2 on which the metal electrical connection terminal 1121 is not molded. A circumferential dimension of the first radial coupling part 1113-1 is smaller than that of the second radial coupling part 1113-2.SELECTED DRAWING: Figure 2
