Problems solved by technology

[0003] Usually, in order to improve the heat dissipation of the asynchronous motor and reduce energy waste, a fan is usually installed on the shaft at the end of the asynchronous motor to speed up the air flow, thereby improving the heat dissipation efficiency, and a cover is installed to protect the fan. The holes can realize the circulation of gas, but the air contains a lot of dust, and the cover cannot block the dust from entering with the air. When the asynchronous motor is in use, the dust is not easy to accumulate due to the circulation of the air, but when the motor is not in use, the dust will It is easy to enter the motor through the holes on the cover, thus accumulating inside the motor. The dust entering the motor is not easy to clean. After a long time, the dust will accumulate more, which will not only affect the heat dissipation function of the motor, but even affect the motor. However, if the asynchronous motor is turned on for cleaning, not only the operation is complicated, but also the equipment where the asynchronous motor is located cannot operate normally, and time and energy are wasted for maintenance. If the asynchronous motor is directly replaced without maintenance, it also increases production costs. Therefore, there is a need for an asynchronous motor that can dissipate heat normally and prevent dust
