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: A commutator has a conductive layer, a segment layer and an insulating layer separating the conductive layer and the segment layer. The segment layer includes multiple commutator segments. A mounting hole is defined along an axis of the commutator passing through the conductive layer. The three-layer structure of the commutator forms a capacitor having an increased confronting area and reduced inter-plate distance. The capacitor thus has a greater capacitance and hence greater EMI absorbing capability, making it possible to reduce EMI emissions without additional EMI reduction components outside the commutator. A rotor and a motor employing the commutator are also disclosed.
