Abstract An electric motor includes an end cap assembly to perform reliable ground connection under high temperature and strong vibration environments. The electric motor includes the end cap assembly having ground connection. The motor comprises: a housing (1); brushes (2, 4); a brush assembly (3) including an electrical component (RLC) and a terminal holder (31); an end cap (5); and a ground plate (7). The brush assembly is fixated on an open end of the housing. The end cap (5) is arranged outside the brush assembly (3) and is fixated on the housing (1). The plate (7) is arranged by being elastically compressed between the terminal holder (31) and the end cap (5). The plate includes a plurality of elastic structures (73,75). Each of the elastic structures supports a lead corresponding to at least a part of an electrical component (RC). The ground plate (7) completes the ground connection by being electrically connected to at least one of the housing (1) and the end cap (5). 전기 모터가 접지 연결을 갖는 단부 캡 조립체를 갖는다. 모터는 하우징(1), 브러시(2, 4), 전기 부품(RLC) 및 단자 홀더(31)를 포함하는 브러시 조립체(3), 단부 캡(5) 및 접지 플레이트(7)를 갖는다. 브러시 조립체는 상기 후이징의 개방 단부에 고정된다. 상기 단부 캡(5)은 브러시 조립체(3)의 외부측 상에 위치되고 상기 하우징(1)에 고정된다. 상기 플레이트(7)는 상기 단자 홀더(31)와 상기 단부 캡(5) 사이에 탄성적으로 압축되어 배치된다. 플레이트는 복수개의 탄력 구조체(73, 75)를 포함한다. 각각의 탄력 구조체는 전기 부품(RC) 중 적어도 일부의 대응하는 리드를 탄성적으로 지탱한다. 접지 플레이트(7)는 하우징(1)과 단부 캡(5) 중 적어도 하나에 전기적으로 연결되어 접지 연결을 완성한다.
