Maintenance method in which the electric fan does not turn because the electric fan does not turn

Electric fans are the most commonly used electrical appliances in addition to air conditioners in summer. Without air conditioners, electric fans are needed to dissipate heat and improve the hot environment. When using an electric fan, some people find that the electric fan does not turn. At this time, it is necessary to understand the reason why the electric fan does not turn, and also need to repair the electric fan that does not turn. The following describes the maintenance method for the electric fan not turning.

First, the reason why the electric fan does not turn

1, the electric fan usually does not pay attention to maintenance, long-term lack of lubricating oil. The fan shaft part is to ensure that there is oil, otherwise the motives on the fan blades cannot be dragged. If you are at home, you can choose to turn off the power, then move the blade, if the rotation is stiff, basically there is no lubricant.

2. The electric fan has been used for too long and causes wear. If a fan is used for a long time, the motor will be worn out and the bushing of the motor will burn off easily after it has worn out.

3. The weather is too hot or the engine is overheated and it does not turn. There is a motor in the fan's device. There is a thermal circuit breaker in the motor. If a short circuit occurs in the coil winding, the heat will increase in a short time. In this case, the motor will "strike".

4. The starting capacitor capacity becomes smaller. After the electric fan has been used for a long time, its capacity will be reduced, resulting in a small starting torque of the motor and failure to drive the load.

5. The electric fan has a fault on the electrical, such as line damage.

Second, the maintenance method of the electric fan does not turn

1. The reason why the fan blades do not turn many times is because the maintenance is too bad. If you turn the power and turn the blade to turn stiff after turning off the power, you should use some lubricant to drip into the shaft so that it can be lubricated without affecting the motive to drag the blades.

2, for the blade caused by wear does not rotate, you need to replace the parts, especially the bushing, if burned easily burned.

3. If the capacitor capacity is small, the fan will not turn. Replace the capacitor and replace it. Replace it with a new capacitor of the same model. It is recommended to select 20% larger than the original capacitor, which will have a better turning effect.

4. If the axial clearance of the rotating shaft is too large, you can choose to adjust the gasket after disassembling the motor. But remember that when installing the motor back, be careful that the rotor must be concentric with the bearing. Lubricate the screws slowly and diagonally. Finally, use a wooden handle to knock the shaft to ensure it is concentric. It is very easy to dismantle the motor, but it is more difficult to put it back. Don't just casually, otherwise it is easy to repair the fan. If you find that the bush wear is serious when you remove the motor, you should replace it with a new one.

5. If it is because of electrical failure, you can check the wiring of the wiring, sometimes the damage of the cable, etc., and repair it according to the problems it has.

Remind everyone that only knowing the reason why the electric fan does not turn, can understand the maintenance method of which electric fan does not turn, so as to solve the problem that the electric fan does not turn. When using an electric fan, it will be a malfunction. When it fails, there is no need to be so nervous. You can try it yourself and you can't repair a professional technician.
