1, poor maintenance, long-term lack of lubricants.
This is the most common reason why the fan does not turn, so you can consider it first. 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. Wear caused by long time.
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. Moreover, the internal resistance of the motor is also increased at this time, the load capacity is low, and the blades are not easily rotated. Long-term wear will also leave the gap between the shaft and the shaft too large for the blades to rotate.
3. The fan caused by overheating 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". In addition, if the motor is too hot, the load capacity will be correspondingly deteriorated, which will cause the power to become low and unable to drive the blades to rotate.
4. Electrical faults, such as line damage.
Regardless of the electrical appliance used, care should be taken to maintain it. Otherwise, the aging of the motor will affect the function.
5. The starting capacitor capacity becomes smaller.
When the fan is used for a long time, the capacity of the capacitor will decrease, causing the motor starting torque to become small and unable to drive the load. Http://news.chinawj.com.cn

The application of Si3N4 ceramics on automotive engines has opened up a new dimension for the development of new high-temperature structural materials. The automobile industry itself is a multidisciplinary industry that integrates all kinds of science and technology. China is an ancient civilization with a long history. It has made brilliant achievements in the history of ceramic development. With the progress of reform and opening up, one day, China also It is bound to be among the world's major auto industry countries, creating new glory for the development of ceramics.
