Abstract

A feed axis motor includes a front-side housing fixed to an end face of a stator core. The stator core is formed of a material with iron as a main component. The front-side housing is formed of a material with aluminum as a main component. The stator core and the front-side housing are coupled with each other at a welding mark generated by laser welding. The welding mark extends in a circumferential direction so as to cover a line of contact between the stator core and the front-side housing. The welding mark seals the boundary portion between the stator core and the front-side housing.
