[0002] An automotive motor refers to an electric motor specifically used to drive a car. It plays a very important role in a car. The main function of an automotive motor is to convert electrical energy into mechanical energy to provide power for the car.

[0003] The motor housing is one of the main components of the mechanical structure of the automobile motor. It is not only a good protective shell for the motor stator and rotor, but also plays a role in protection and fixing during use. It is also a barrier to prevent external impurities such as dust and moisture from entering the motor. In order to improve the protective performance of the motor housing, the surface of the motor housing needs to be sprayed during the production and processing. However, in the traditional spraying operation, a single-sided spraying method is generally used, that is, the inner and outer surfaces of the motor housing are sprayed in turn, which takes a long time and is inefficient. For this reason, the present application proposes a spraying device for automobile motor housing. Utility Model Content
