Abstract

The invention relates to a structure of a vehicle motor. The vehicle motor comprises a motor stator, a motor rotor, a motor front end cover, a motor rear end cover and a motor housing, wherein a front pressure plate and a rear pressure plate are arranged on the front and rear end surfaces of the core of the motor stator respectively; the motor front end cover and the motor rear end cover are in positioning connection with the front pressure plate and the rear pressure plate of the core of the motor stator in a female end manner, and are assembled together with the motor stator, and then mounted into the motor housing; heat emission holes are formed in the surface of the motor housing. The vehicle motor adopting the structure has the advantages that the cooling effect is good; the generality is high; dependence on a liquid cooling circulation device of a vehicle is avoided; the weight of the motor housing is further reduced effectively to ensure that the total weight of the motor is controlled to be in a reasonable range meeting requirements.

Description

technical field [0001] The invention relates to the field of motors, in particular to the structure of a vehicle motor. Background technique [0002] At present, there are two main heat dissipation methods for automotive motors: air cooling and liquid cooling. Liquid cooling is effective, but the structure of the motor is complicated due to the need to design a special water channel, and its cost is high, and it is only suitable for cooling with liquid circulation. System vehicles; air cooling generally dissipates the heat of the stator core and coils through air flow or cooling fins, and the cooling effect is worse than that of liquid cooling. [0003] Under the general motor structure, the assembly method of the motor casing is that the formed stator is pressed into the motor casing by external force, and then the casing is connected and fixed with the front and rear end covers of the motor, and the motor casing plays the role of supporting the stator and protecting it. T...
