The stator 20 is configured by letting.

이상과 같이 구성된 스테이터(20)는, 전기 자동차의 후륜 구동용 클러치 시스템에 장착되는데, 좀 더 구체적으로는 전기 자동차의 후륜 구동용 모터와 연결된 감속기에 장착되어 모터의 구동력을 휠(Whell)에 전달 또는 해제시켜주는 작용을 하는 것으로서, 스테이터(20)의 내측에 설치된 트랜슬레이터를 상, 하로 작동시키는 작용을 하는 것으로 이러한 작용은 일반적인 것이어서 구체적인 설명은 생략하고, 스테이터(20)의 작용만을 설명한다.The stator 20 configured as described above is mounted on a clutch system for driving rear wheels of an electric vehicle, and more specifically, is mounted on a reducer connected to a rear wheel driving motor of an electric vehicle to transmit the driving force of the motor to the wheel.
