In summer, people choose to use electric fans mainly to achieve cool air, so that they will feel particularly cool, but there is an electric fan for some reason, there is always no wind, which makes many people feel uncomfortable When you are particularly sleepy, you should know the reason why the fan has no wind. In addition, you should know what to do if the fan does not turn.
Why is the fan not blowing?
1. If the motor is used for a long time, the internal resistance of the motor will also increase, and the load capacity will become lower, so that the fan blade cannot be driven to rotate. Also, if the axial clearance of the motor shaft is too large, it will also cause the load to be unable to be dragged. Also, you have to consider how long the electric fan has been used, the motor of the electric fan will be worn out, and the bushing of the motor will easily burn out after being worn.
2. Most people may encounter the following phenomenon. The electric fan does not turn. You can pull it out by hand or it will take a long time to slowly turn it up. will move.
3. The possible reason for this phenomenon is that the starting capacitor in the fan becomes smaller, which is not enough to make the motor rotate. When the electric fan does not rotate, the first thing to think about is that the motor is not lubricated. When the fan blade is installed on the top and the motor cannot be dragged, it will be found that the rotating shaft can still run normally after removing it, which means that the fan motor is not broken. Then after disconnecting the power supply of the fan, you will find that the rotation of the fan blade is a little stiff when you gently move the fan blade, which means that the fan oil is gone. If the fan rotates easily, it means that the fan is well lubricated.
