Abstract
An improved electric motor casing is disclosed. The end casing includes a circular end plate and perpendicular peripheral side wall with a plurality of rectangular, internally projecting lands formed in the side wall. Each land defines a linear ledge with the plurality of linear ledges disposed in the same plane to receive and support the electric motor stator. The casing is formed by drawing a flat metal blank into the end plate and perpendicular side wall, with the plurality of rectangular lands drawn substantially simultaneously with formation of the end plate and perpendicular side wall.
