Abstract
A motor housing may include a cast body. The cast body may include a cylindrical portion. At least one machined surface may be disposed on at least one of (i) an inner peripheral surface of the cylindrical portion and (ii) an outer peripheral surface of the cylindrical portion. A back side of the at least one machined surface may be an exposed non-machined surface.

A motor housing, comprising:
- a cast body including a cylindrical portion;
- at least one machined surface disposed on at least one of (i) an inner peripheral surface of the cylindrical portion and (ii) an outer peripheral surface of the cylindrical portion;
- wherein a back side of the at least one machined surface is an exposed non-machined surface;
- wherein the at least one machined surface includes an outer machined surface disposed on the outer peripheral surface;
- and
- wherein the outer machined surface is arranged on a convex portion that protrudes from a non-machined surface disposed on the outer peripheral surface.
