The bottom end of the end cap is provided with a fourth oil passage; the bottom end of the motor housing is provided witha third oil passage.

Description

technical field [0001] The invention belongs to the technical field of electromechanical equipment, in particular to an automobile motor cooling system and an automobile motor. Background technique [0002] As the power source of electric vehicles and hybrid vehicles, automotive motors provide power for electric vehicles and hybrid vehicles. The working current and high speed required by the automobile motor work, therefore, the automobile motor itself will generate a lot of heat, if the heat cannot be discharged in time, it will have great side effects on the stable operation of the automobile motor, and even the automobile itself . Therefore, it is necessary to provide an automobile motor cooling system. [0003] The automobile motor cooling system provided by the related art includes: a motor casing, an end cover, a rotating shaft, a stator, a rotor, a cooling jacket and an oil pump. The rotor is located on the rotating shaft in the motor casing, the stator is sleeved ...

AI Technical Summary

Problems solved by technology

[0005] There is a cooling jacket on the stator, and it is difficult for the cooling oil to pass through the cooling jacket to achieve efficient cooling and lubrication of the motor, resulting in low operating efficiency of the motor, and the cooling jacket on the stator needs to increase the volume of the motor, which in turn makes the motor occupy the overall space of the car. Increased space
