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 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.
