[0002] A fan is a household appliance that uses an electric motor to drive the fan blades to rotate to accelerate the flow of air. It is mainly used for cooling and air circulation. With the improvement of people's living conditions, the requirements for the use of fans have gradually increased. Therefore, silent fans have gradually replaced the use of old-fashioned fans, and are deeply loved by people because of their low noise and stable wind force.

[0004] The reason for this problem is that currently, fans mainly rotate by being driven by an electric motor. There are many types of fans, and desktop fans are one of them. Due to the small overall size of desktop fans, the motor is usually directly fixed on the back shell of the fan. When the fan blades rotate, they will generate static electricity by rubbing against the air, and it is easy to adsorb charged dust on the fan. Therefore, it needs to be cleaned regularly. During the process of cleaning the fan shell, it is easy for some water to flow to the motor, resulting in the situation of motor short circuit. In view of the deficiencies of the prior art, we propose a motor of a silent fan to solve the above problems. Content of the Utility Model
