Abstract: An electric motor includes a stator and a rotor. The stator includes a motor housing with an open end and an end cover mounted to the open end. The rotor includes a rotor shaft that extends through the end cover. The end cover includes a bearing that supports the rotor shaft. The rotor shaft and motor housing are made of an electrically conductive material and are electrically connected with each other. The motor housing, end cover, bearing and rotor shaft cooperatively form an electromagnetic shield suppressing electromagnetic interference generated by the motor. Optionally, the rotor shaft drives a coaxial worm shaft of a gearbox by an insulating member, which further suppresses electromagnetic interference.

Abstract: A gear motor assembly includes a casing having a through hole, a motor fixed to the casing, an output shaft, a gear fixed to the output shaft and driven by the motor, and a substantially tubular bearing fixed in the through hole of the casing. The gear has a central hub which has an axial end surface, and a shaft portion extending from a central portion of the axial end surface of the central hub. The shaft portion is sleeved in the bearing. A slot is formed in the outer surface of the shaft portion and is filled with lubricant. The slot extends from a free end of the shaft portion to a joint between the outer surface of the shaft portion and the axial end surface of the central hub.
