1. Poor maintenance and long-term lack of lubricating oil. The part of the fan shaft is to ensure that there is lubricating oil, otherwise the motive of the fan blade on it will not be able to drag. If you are at home, you can choose to turn off the power and then turn the fan blade. If the rotation is stiff, there is basically no lubricating oil.
2. Wear and tear caused by prolonged use. If a fan is used for a long time, the motor will be worn out, and the shaft sleeve of the motor will easily burn out after being worn.
3. The fan does not rotate due to overheating. 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 generation will increase in a short time, and the motor will stop working.
4. The starting capacitor capacity becomes smaller. When the fan is used for a long time, the capacitance of the capacitor will be reduced, resulting in a smaller starting torque of the motor and unable to drive the load.
5. Electrical faults, such as line damage
