The invention provides an oil cooling motor, a power assembly and a vehicle. The oil cooling motor comprises a stator and a rotor, a rotor shaft sequentially penetrates through a first end plate, a rotor iron core and a second end plate in the circumferential direction of the oil cooling motor, an oil cooling loop of the rotor comprises an oil inlet channel and a plurality of oil outlets, the oil inlet channel is distributed in the rotor shaft, and the oil outlets comprise a plurality of first oil outlets and a plurality of second oil outlets; the multiple first oil outlets are distributed in the side, away from the rotor iron core, of the first end plate at intervals in the circumferential direction of the oil-cooled motor, and the multiple second oil outlets are distributed in the side, away from the rotor iron core, of the second end plate at intervals in the circumferential direction of the oil-cooled motor. At least one of the area of each first oil outlet and the area of each second oil outlet or the distance between each first oil outlet and the inner circumferential face of the stator and the distance between each second oil outlet and the inner circumferential face of the stator in the radial direction of the oil cooling motor is different. Cooling oil in different states can be sprayed out of the two ends of the rotor of the oil-cooled motor to meet different oil cooling requirements of the two ends of the stator winding.

    本申请提供了一种油冷电机、动力总成及车辆。该油冷电机包括定子和转子,转子轴沿油冷电机的周向依次穿过第一端板、转子铁芯和第二端板,转子的油冷回路包括:进油通道以及多个出油口,进油通道分布于转子轴的内部,该多个出油口包括多个第一出油口和多个第二出油口;其中,多个第一出油口沿油冷电机的周向间隔分布于第一端板背离转子铁芯的一侧,多个第二出油口沿油冷电机的周向间隔分布于第二端板背离转子铁芯的一侧,每个第一出油口和每个第二出油口的面积或沿油冷电机的径向每个第一出油口和每个第二出油口与定子的内周面的间距中至少一个不相同。该油冷电机的转子两端能够喷出不同状态的冷却油满足定子绕组两端不同的油冷需求。
