Abstract: A brush assembly includes a circuit board, at least two brushes, power connecting terminals for connecting with an external power supply, and a power supply branch circuit connected in series between a corresponding one of the power connecting terminals and a corresponding one of the brushes. The brush assembly further comprises an EMI suppressor connected between the power supply branch circuit and ground. The EMI suppressor is an axial capacitor formed by a conductor core, a cover, and a filling medium. The cover is attached around the conductor core, and the filling medium is filled between the conductor core and the cover. A motor utilizing the brush assembly is also provided.

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: An end cap assembly includes an end cap. The end cap includes an end wall, a sidewall, and a shielding member. The sidewall projects from one side of the end wall. The sidewall defines a cutout for allowing two conducting wires to pass therethrough, and the two conducting wires connect components mounted within the end cap to an external power source. The shielding member is disposed in the cutout. The end cap assembly provides enhanced EMI suppression. In addition, the present invention also provides a motor employing the end cap assembly.
