The present invention relates to a power train of an electric vehicle, which comprises: a planetary gear apparatus of which a first rotational element is connected with a first shaft, a second rotational element is connected with a second shaft, and a third rotational element is connected with a third shaft, among three rotational elements; a first motor which is installed to supply constant power to the first shaft; and a second motor which is installed to supply constant power to the second shaft. The third shaft is installed to be fixable on a transmission case. Arbitrary two shafts among the first shaft, the second shaft, and the third shaft are constituted to restrain mutual rotation. The present invention minimizes capacity of a motor by providing a plurality of gear ratios while satisfying a maximum climbing performance and a maximum speed performance.

    본 발명은 3개의 회전요소 중 제1회전요소가 제1축에 연결되고 제2회전요소는 제2축에 연결되며 제3회전요소는 제3축에 연결되는 유성기어장치; 상기 제1축에 상시 동력을 공급할 수 있도록 설치된 제1모터; 상기 제2축에 상시 동력을 공급할 수 있도록 설치된 제2모터를 포함하여 구성되고, 상기 제3축은 변속기케이스에 고정 가능하게 설치되며, 상기 제1축, 제2축 및 제3축 중 임의의 두 축은 상호 회전을 구속할 수 있도록 구성된다.
