The first thing to consider when the electric fan is not spinning is that the motor is not properly lubricated. When the fan blades are installed on it and the motor is not moving, you will find that the shaft can still. works normally after being removed. This means the fan motor is not broken.
There is also a factor related to the duration of use of the electric fan. The electric fan motor will wear out, and the motor shaft sleeve will burn easily after wear. If the motor is used for a long time, the internal resistance of the motor will also increase and the load capacity will decrease, resulting in the inability to rotate the fan blades. In addition, if the axial play of the motor rotating shaft is too large, the load will also not be able to be dragged.
Another situation is that the electric fan stops spinning. You dPlease pull it with your hands or it will take a long time to start rotating slowly. After using it for a while, you notice that it starts to spin. Does not work even if you remove it with your hands. The possible reason for this phenomenon is that the fan start capacitor has become smaller and is not enough to run the motor.

How to maintain electric fans:
1. Before using the electric fan, read the instruction manual in detail to fully understand the structure of each part of the electric fan and the correct usage method. Electric desk and floor fans should use three-conductor plugs and receptacles with safety grounding wires; Ceiling fans should be installed at a higher position from the ceiling and noNo ground wire is required.
2. The blade of an electric fan is an important component Whether during installation, disassembly, scrubbing or use, it must be protected to prevent deformation. Clean the electric fan regularly to prevent dust from affecting the operation of the electric fan.
3. After prolonged use of a general electric fan, a lot of dust easily accumulates on the fan blades. At this point, the dust on the fan blades should be cleaned off. Be careful not to use gasoline or strong alkali to wipe, so as not to damage the surface paint.
4. Once summer is over, the electric fan should be stored well. Before storing, the electric fan should be thoroughly cleaned, then wrapped in a cloth cover and placed in a dry and stable environment.
