[0031] In the above embodiment, a dustproof channel is formed by the dustproof groove 31 on the end cover 3 and the dustproof part 21 on the rotating element 2. When the rotating element 2 rotates, the dustproof part 21 enters the dustproof groove 31, effectively blocking dust, debris, etc. from entering the interior of the motor, thereby achieving a good dustproof protection effect. Dust and debris inside the motor may affect the normal operation of the motor and even damage key components. By adopting this dustproof structure, the possibility of dust and debris entering the interior of the motor can be effectively reduced, thereby extending the service life of the motor. The application of the dustproof structure can reduce the probability of motor failure and improve the reliability of the motor. Preventing dust and debris from accumulating and damaging the interior of the motor helps to maintain the normal operation of the motor and reduce the need for maintenance and replacement. The design of the dustproof structure makes cleaning and maintenance work more convenient. It is only necessary to clean the dustproof groove 31 and the dustproof part 21, without disassembling the entire motor housing, reducing the time and cost of maintenance.

In this embodiment, unlike the above-mentioned embodiment, the end cap 3 can be single. Specifically, by fitting one end of the shell 1 on the connecting step 34, a stable connection between the shell 1 and the end cap 3 can be achieved. The connecting step 34 provides a solid support platform, so that the end cap 3 and the shell 1 can be closely combined together, increasing the stability and reliability of the entire structure. The setting of the assembly platform 33 provides convenience for the assembly process. The design of the matching ring 32 and the connecting step 34 allows the end cap 3 to be easily installed on the shell 1, saving assembly time and workload. The presence of the connecting step 34 can increase the strength and rigidity of the entire structure.
