Why does the fan spin when X-Trail turns on the heater?

When the temperature of the Qijun water tank is high, the electronic fan rotates at a high speed. The working principle of the electronic fan is that the car electronic fan is controlled by the thermostat. When the water temperature rises to the upper limit, the thermostat turns on the power and the fan starts working. When the water temperature drops to the lower limit, the thermostat turns off the power and the fan stops working. The following are the reasons why the electronic fan does not rotate: 1. Poor motor lubrication. The reason why the electric fan does not rotate is because the motor is not well lubricated and the motor cannot move after the fan blades are installed. 2. The motor is overheated. Overheating of the motor will also cause the motor's load capacity to deteriorate. The effective power becomes lower and the load cannot be driven; 3. The starting capacitor capacity becomes smaller, causing the motor's starting torque to become smaller and unable to drive the load; 4. The motor is used for too long and if the electric fan is used for a long time, the motor will The shaft sleeve of a loss motor is easy to burn after being worn. If the motor is used for a long time, the internal resistance of the motor will also increase and the load capacity will decrease, resulting in the inability to drive the fan blades to rotate.
