ABSTRACT:
An end shield for mounting on a stack of laminations forming the stator of an electric motor. The end shield has an inner face facing the stack, mounting openings alignable with holes extending into the stack, and a spacer on the inner face adjacent at least one of the openings to space the inner face from the stack so that a threaded fastener extending through the mounting opening and into a hole in the stack can more readily pull material surrounding the hole upwardly to form a protuberance on the stack to engage and resist movement of the end shield relative to the stack. The motor incorporates at least one end shield of this construction. According to the method of this invention, at least one end shield is installed on the stator.
