The present invention relates to a drive motor (1) which is applied to an echo-friendly vehicle (100) wherein the drive motor has a coil multi cooling path (10) including a coil cooling path (20), an engine clutch cooling path (30), and a resolver cooling path (40). An oil flow amount of an engine clutch and a resolver, which is gathered by a centrifugal force of a rotor sleeve (4) with a connection action of the coil cooling path (20), the engine clutch cooling path (30), and the resolver cooling path (40), is simultaneously scattered in front and rear directions of a coil (9) and wets the coil so as to maximize whole cooling performance efficiency of the coil (9). Particularly, an oil flow amount, which is enough by adding the oil flow amount of the engine clutch to the oil flow amount of the resolver, is scattered toward the coil (9) so as to generate a direct cooling effect to a space of a stator (7) during an oil scattering process.
본 발명의 친환경차량(100)에 적용된 구동 모터(1)에는 코일냉각패스(20)와 엔진클러치 냉각패스(30) 및 레졸버 냉각패스(40)로 이루어진 코일 멀티냉각패스(10)가 구비되고, 코일냉각패스(20)와 엔진클러치 냉각패스(30) 및 레졸버 냉각패스(40)의 연계 작용으로 로터 슬리브(4)의 원심력으로 모아진 엔진클러치/레졸버 측 유량이 코일(9)의 앞뒤쪽 방향으로 동시에 비산되어 적셔줌으로써 코일(9)의 전체적인 냉각성능 효울이 극대화되고, 특히 엔진클러치 측 유량이 레졸버 측 유량과 합쳐져 충분한 오일 유량이 코일(9)족으로 비산됨으로써 오일비산과정에서 스테이터(7)의 공간에 대한 직접적인 냉각효과도 발생되는 특징을 갖는다.
