Abstract: An electric motor has an end cap assembly having a ground connection. The motor has a housing, a brush assembly including brushes, electrical components and a terminal holder, an end cap, and a ground plate. The brush assembly is secured in an open end of the housing. The end cap is positioned on an outer side of the brush assembly and fixed to the housing. The ground plate is disposed between and is resiliently compressed by the brush assembly and the end cap. The plate includes a plurality of elastic structures. Each elastic structure resiliently bears against corresponding leads of at least some of the electrical components. The ground plate is electrically connected to at least one of the housing and the end cap to accomplish a ground connection.

Abstract: An electric motor has a stator, a rotor, two motor terminals and a filter circuit for suppressing electromagnetic interference. The filter circuit includes a flexible circuit assembly having a FPCB. Multiple filter elements are mounted to the FPCB. There are less connection points between the filter circuit and the motor terminals, which leads to higher reliability of the motor.
