Abstract: A motor, a powertrain, and a vehicle. The motor may be applied to an electric motor vehicle/electric vehicle, a pure electric vehicle, a hybrid electric vehicle, a range extended electric vehicle, a plug-in hybrid electric vehicle, a new energy vehicle, battery management, a motor & driver, a power converter, a reducer, or the like. The motor is configured to output power. In a process of outputting power by the motor, a blocking member arranged in the motor blocks the contact between a rotor of the motor and a coolant, so that the coolant does not splash under the centrifugal action of the rotor in the process of rotation, thereby avoiding the kinetic energy consumption of the rotor. Therefore, a rotating speed of the motor is faster, and the output power is greater.

Abstract: This application provides a motor cooling system of an electric vehicle. In the cooling system, a coil cooling oil passage includes a first oil outlet that is at an end portion of a stator core. A core cooling oil passage and the coil cooling oil passage are sequentially connected. In this case, cooling oil first enters the core cooling oil passage, and then enters the coil cooling oil passage. The core cooling oil passage extends in a circumferential direction of the stator core. The coil cooling oil passage extends in an axial direction of the stator core. A power apparatus drives the cooling oil to enter the core cooling oil passage from an oil inlet, flow through the core cooling oil passage, and enters the coil cooling oil passage from an oil through port. The cooling oil flows back to an oil return groove from the first oil outlet.
