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.
