Abstract

An outer rotor motor has a bearing housing with reduced machining and material costs, can be assembled with high accuracy, and has favorable durability. A bearing is attached to an inner circumferential surface of a housing main body that has been formed in a cylindrical shape by plastic deformation caused by press molding a metal matrix. At least one protruding surface is formed by plastic deformation so as to protrude further outward than the housing main body, and the stator core is attached to the outer circumference-side of the at least one protruding surface.
