The present invention relates to a speed detection sensor of a driving motor for an electric vehicle which is simplified and strong as a structure including a waterproof function, increases durability and measurement performance by improving a structure of being mounted on a motor and reduces manufacturing costs. The speed detection sensor of a driving motor for an electric vehicle comprises: a body unit including a cylindrical fore-end unit of which one side is sealed, a fixing unit having a coupling hole formed on one side and a coupling unit having a groove formed on one side and coupled with a sealing unit; a PCB unit of which two hole sensor units are installed on the fore-end unit and inserted and mounted on the body unit; a silicone filling stored inside the body unit; a sealing unit sealed and coupled to a rear surface of the body unit; and a cable unit connected between the body unit and the sealing unit. The cylindrical fore-end unit of the body unit is inserted and mounted on a hole formed on a rear surface of a protrusion unit of the driving motor and one end of the cylindrical fore-end unit is closely installed to a toothed wheel for measuring interlocked with a rotation shaft.

    본 발명은 방수기능을 포함한 구조로 간단하고 견고함과 동시에 모터에 장착되는 구조를 개선하여 내구성 및 측정 성능을 향상시키고 제조비용은 절감시킨 전기차량용 구동모터의 속도감지센서에 관한 것으로, 일측이 밀폐된 원통형 선단부와, 일측에 체결공이 형성된 고정부와, 요홈이 일측에 형성되며 밀폐부와 결합되는 결합부를 포함하는 본체부; 선단부에는 2개의 홀센서부가 설치되고 상기 본체부에 삽입 장착되는 PCB부; 상기 본체부 내부에 충전되는 실리콘 충전재; 상기 본체부의 후면에 밀봉 결합되는 밀폐부; 및 상기 본체부와 밀폐부 사이에 연결되는 케이블부를 포함하고; 상기 본체부의 원통형 선단부가 구동모터의 후면돌출부에 형성된 구멍에 삽입 장착되며, 상기 원통형 선단부의 단부가 회전축과 함께 연동하는 측정용 톱니바퀴부에 근접하도록 설치된 것을 특징으로 한다.
