According to the present invention, an oil coil circulation type motor of an eco-friendly vehicle comprises an oil coil circulation device (10) which has cooling oil chambers (39-1, 39-2) through which cooling oil that is pumped by an oil pump (100-1) is introduced and discharged and which are formed along the circumference of a stator core (3), wherein the cooling oil enters the cooling oil chambers (39-1, 39-2) to wet a stator coil (4) wound around the stator core (3) and then flows out from the cooling oil chambers (39-1, 39-2). Accordingly, as compared to an oil cooling jacket type, an oil shaft scattering type, and an oil direct injection type that are applied conventionally, the present invention exhibits high cooling efficiency, thereby increasing the capacity and enhancing the output density. Particularly, since the oil coil circulation device (10) is applied with an oil coil circulation type, the motor has characteristics suitable for a concentrated type motor for a transmission mounted electric device (TMED).

    본 발명의 친환경차량의 오일 코일순환방식 모터는 오일펌프(100-1)로 펌핑되는 냉각유가 유입과 배출되는 냉각유 챔버(39-1,39-2)를 스테이터 코어(3)의 둘레를 따라 형성하고, 냉각유가 냉각유 챔버(39-1,39-2)로 들어와 스테이터 코어(3)에 권취된 스테이터 코일(4)을 적셔준 후 냉각유 챔버(39-1,39-2)에서 빠져 나가는 오일 코일순환장치(10)로 구성됨으로써 기존의 오일 냉각재킷방식과 오일 축 비산방식 및 오일 직분사방식 대비 고 냉각효율로 용량증대와 출력밀도향상이 이루어지고, 특히 오일 코일순환장치(10)의 오일 코일순환방식으로 TMED(Transmission Mounted Electric Device)용 집중권타입 모터에 적합한 특징을 갖는다.
