What is the reason why the electric fan does not turn?

The reasons why the electric fan does not turn are as follows:

1. Poor maintenance and long-term lack of lubricating oil. The fan shaft part is to ensure that there is lubricating oil, otherwise the fan blade on the motive cannot be dragged. If you are at home, you can choose to turn off the power and then flip the fan blades, if you rotate, it proves that there is no damage.

2. Wear and tear caused by long-term use. If a fan is used for a long time, the motor will wear out, and the shaft sleeve of the motor will easily burn out after wearing.

3. The fan does not rotate due to overheating. There is a motor in the fan device, and there will be an overheating circuit breaker in the motor, if there is a short circuit in the coil winding, the heat will increase in a short time, and the motor will stop in this case.

4. The capacitance of the starting capacitor becomes smaller. When the fan is used for a long time, the capacitance capacity will decrease, resulting in the starting torque of the motor becoming smaller, and the load cannot be driven.

The general solution is to add a little lubricating oil to the shaft of the electric fan motor. If it doesn't work, you can consider replacing the motor with a new one, or find a professional to check and repair it. The specific inspection method can be to toggle the fan blade by hand in the event of a power failure to observe whether the rotation of the fan blade is stagnant.

Other reasons why the electric fan does not rotate:1Poor maintenance, long-term lack of lubricating oil.

The rotating shaft part of the fan is guaranteed to have lubricating oil, otherwise the motor cannot drag the fan blades. If you are at home, you can choose to turn off the power first and then turn the fan blades. If the rotation is stiff, there is basically no lubricating oil.

2.It is difficult to turn due to long-term wear and tear. If a fan is used for a long time, the shaft sleeve of the motor will wear out and it will be difficult to rotate.

3.The fan does not spin due to overheating. There is a motor in the fan unit, and there will be a thermal circuit breaker in the motor.

If the coil windings are short-circuited, the heat will increase in a short period of time, making the motor "strike" and not move. 4.The capacitance of the starter capacitor becomes smaller.

When the fan is used for a long time, the capacitance capacity will be reduced, resulting in a small starting torque of the motor and the inability to drive the load.

This problem can not be underestimated, the temperature is too high to affect the performance of the vehicle, it is easy to cause accidents, to check carefully: 1. See if the water temperature relay is broken, and replace it if the contact is poor or does not respond. 2. The temperature control switch is damaged, resulting in the inability to power the fan when the water temperature is high.

3. If the fan is damaged, it may be that the load of the fan is too large or the short circuit is burned out, so replace it with a new one.

What's going on with the electric fan not turning.

The bearing lacks lubrication, has high resistance and high noise. Electric fans need to be lubricated frequently to run smoothly.

Most of the well-known electric fan factories such as Beriaco use fully synthetic electric fan lubricants from Hotolube or Kluber. Fully synthetic base oil production, clear and transparent, colorless and odorless, low temperature resistance, no dust. Tao Feng has a 120ml white sharp mouth small oil bottle, just drop a few drops, easy to use.

It is not suitable to use ordinary engine oil and butter, which will volatilize quickly in summer and will have an unhealthy odor. ,

What's going on with the electric fan not turning.

The electric fan at home has been used for a long time and is prone to malfunction. So what is the reason why the electric fan does not turn? PChouse will take you to find out.

1. The motor does not rotate due to overheating.

If the motor inside the fan is overheated, it will cause the phenomenon of not rotating. There is a motor in the fan device, and there is an overheating circuit breaker in the motor, if there is a short circuit in the coil winding, the heat will increase in a short time, so that the motor will not rotate.

Solution: If you understand this knowledge, you can disassemble and deal with it yourself, but if you can't solve it yourself, you can let professionals clean the cooling fan of the motor to make the fan work normally.

Second, the lack of lubricating oil leads to non-rotation.

When the fan is in use, it needs lubricating oil to ensure that it rotates. When inspecting, you can turn off the power supply, and then turn the fan blade, if the rotation is relatively stiff, you can basically make a noise to determine that there is no lubricating oil.

Solution: You can drip special lubricating oil into the rotating shaft of the fan so that it can be lubricated, so as not to affect the motor dragging the fan blades. When dripping lubricating oil, pay attention to the dosage, not too much, and get it everywhere. It can't be too little, it won't work.

3. Long-term wear leads to non-rotation.

Fans that are used at home for too long can cause serious wear and tear because the motor will wear out, and the bushings of the motor will easily burn out. If the motor is used for a long time, the internal resistance of the motor will also become larger, and the load capacity will be lower, resulting in the inability to drive the fan blades to rotate and rotate.

Solution: Because of the lack of rotation caused by wear, the more direct method is to replace the parts. If you replace it with a new part, you can use it again.
