However, the existing motor faces many challenges in the working environment, especially the dust problem needs to be solved. The dust and debris in the environment where the motor is located are easy to adhere to the cooling fan blades. To solve this problem, the traditional dustproof shell can block some dust to a certain extent, but there are still obvious defects. The conventional dustproof shell has a simple structure and can only provide basic protection, which cannot meet the dustproof requirements in long-term and harsh working conditions. When the dust accumulates to a certain extent, it is difficult to clean and easy to continue to invade the motor interior through the gap of the dustproof shell. In addition, the existing dustproof device is not convenient to maintain, and the operation is cumbersome when replacing the dustproof part, which needs to disassemble a large number of structures, consumes manpower and time.
