The present invention relates to a rotor assembly of an electric motor capable of maintaining balance against pressure resistance. The rotor assembly of an electric motor comprises: a rotor; a rotation shaft passing through the center of the rotor and coupled with the rotor; and a coupling member coupled to at least one side of the rotation shaft and restricting the movement of the rotor along the rotation shaft. The coupling member includes a body unit having at least one part being in contact with the rotation shaft and a flange unit connected with the body unit. A part of the flange unit is pressed toward the direction of a rotor side, so that the movement of the rotor can be prevented.

    본 발명은 전동기의 로터 조립체에 관한 것으로서, 로터; 상기 로터의 중앙을 관통하며 상기 로터와 결합되는 회전축; 및 상기 회전축의 적어도 일측에 체결되어, 상기 로터가 상기 회전축을 따라 이동하는 것을 제한하는 체결부재를 포함하고, 상기 체결부재는, 상기 회전축과 적어도 일부분이 접촉하는 몸체부; 및 상기 몸체부와 연결되는 플랜지부를 포함하고, 상기 플랜지부의 일부가 상기 로터 측 방향으로 가압됨으로, 상기 로터의 이동이 방지될 수 있다.
