Abstract
A housing for an electric motor includes a cylindrical sleeve and an end shield in the form of a circular disk that fits within the sleeve. The sleeve has tabs that extend inwardly and define stops to locate the end shield in one axial direction and position it perpendicular to the longitudinal axis of the sleeve. The end shield has circumferentially spaced recesses at the outer edge and in the outer surface thereof. The sleeve has protrusions that extend into the end shield recesses with the end shield positioned against the stops. The protrusions and recesses cooperate to locate the end shield in the other axial direction and secure it against rotational movement relative to the sleeve, whereby the end shield is firmly secured perpendicular to the longitudinal axis of the sleeve against both axial and rotational movement.
