Disclosed is a power train for an electric vehicle which reduces current consumption by delaying a part of a load which is transferred to a traction motor though transferring power due to an eddy current. The power train for an electric vehicle comprises: a traction motor which is a driving source of an electric vehicle; a reducer receiving driving power of the traction motor and transferring the driving power of the traction motor to a wheel; and an electromagnetic clutch located between the traction motor and the reducer and transferring the power of the traction motor to the reducer by the eddy current, wherein the reducer receives the driving power of the motor though the electromagnetic clutch.

    본 발명은 와전류에 의한 동력전달을 통해 트랙션 모터에 전달되는 부하를 일부 지연시켜 전류 소모를 저감하는 전기자동차용 파워트레인을 개시한다. 본 발명의 전기자동차용 파워트레인은 전기자동차의 구동원인 트랙션 모터, 상기 트랙션 모터의 구동력을 전달받아 상기 트랙션 모터의 구동력을 차륜에 전달하는 감속기, 상기 트랙션 모터와 상기 감속기 사이에 위치하여 상기 트랙션 모터의 동력을 와전류에 의하여 상기 감속기로 전달하는 전자기 클러치를 포함하며, 상기 감속기는 상기 모터의 구동력을 상기 전자기 클러치를 통하여 전달받는다.
