Description

Technical Field

[0001] The invention relates to a dust-proof structure for a motor. Background Art

[0002] An electric motor is a driving device that converts electrical energy into mechanical energy. A variety of devices can be driven by electric motors. The existing electric motor structure generally includes a casing, a stator, a rotor, and a drive shaft. The stator and rotor are installed inside the casing. The stator is energized to generate a magnetic field to drive the rotor to rotate. The rotor is fixed with a drive shaft, which transmits power to the outside through the drive shaft. The driving of the stator and rotor will generate a large amount of heat, which can generally be dissipated by installing cooling blades on the drive shaft. In order to ensure the cleanliness of the motor casing, a dust net is generally installed at the rear end of the motor casing to prevent dust from entering the motor casing. However, after long-term use, a large amount of dust will adhere to the outer surface of the dust net, which will cause blockage of the airflow and make it very difficult to clean the dust net. Therefore, it is necessary to develop an automatic cleaning structure for the dust net to improve the convenience of cleaning. Summary of the invention
