Abstract
A reinforced motor for reducing amplitude of operational vibrations includes a stator having an open end, a rotor disposed through and centrally of the stator and having at least one end, an end shield mounted to the open end of the stator and having an outer surface and rotatably supporting the rotor at the one end thereof, and an elongated stiffening member attached to or formed on the outer surface of the end shield so as to increase stiffness and reduce bending of the end shield and thereby reduce amplitude of operational vibrations produced by rotation of the rotor relative to the stator. A peripheral portion of the end shield forms an opening for receiving a switch housing. The stiffening member is attached on the outer surface of the end shield adjacent to the switch housing opening.
