Universal 10 Inch 12V 80W Radiator Electric Cooling Thermo Fan With Mounting Kits

Introduction

The role of the cooling fan is to increase the speed and volume of air passing through the radiator. To improve the heat dissipation capacity of the radiator. The fan is usually installed behind the radiator, and the position of the fan should be aligned with the center of the radiator core as much as possible.The working principle of the electronic fan is that the electronic fan of the car is controlled by the thermostat. When the water temperature rises to the upper limit, the thermostat turns on the power and the fan starts to work. 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 turn:

1. The motor is poorly lubricated, and the electric fan does not rotate. It is because the motor is not lubricated, so that the motor cannot be dragged after the fan blade is installed;

2. The motor is overheated, and the overheating of the motor will also cause the load capacity of the motor to deteriorate, and the effective power of the motor will become lower, resulting in the inability to drive the load;

3. When the starting capacitor capacity becomes smaller, the capacitor capacity will become smaller, resulting in a smaller starting torque of the motor, which cannot drive the load;

4. The motor has been used for a long time. If the electric fan is used for a long time, the motor will be worn out. After the shaft sleeve of the motor is worn, it is easy to burn out. When the motor is used for a long time, the internal resistance of the motor will also increase, and the load capacity will become lower, resulting in the inability to drive the fan blades to rotate.
