Abstract

A motor includes a heat sink including an inner region, and an outer region located radially outward from the inner region. An axial thickness of the inner region is larger than an axial thickness of the outer region, the bottom surface of the outer region is located axially above the bottom surface of the inner region, and the inner region and the electronic component at least partially overlap in an axial direction. A bus bar holder is located axially below the outer region and overlaps the inner region in a radial direction.
