What Role Does The Fan Spring Play in The Cooling Fan? How To Select A Spring?

Answer:
The main function of the fan spring is to provide an offset space for the fan to operate, ensuring that the fan blades run on the magnetic centerline.
2. Fix the ball to prevent abnormal sound from moving forward and backward. It can also increase the friction between the fan blades and the shaft center to prevent mechanical noise caused by the ball running inside and outside the circle.
The selection of spring specifications depends on the gravity and magnetic strength of the fan, and the larger the gravity and magnetic strength, the thicker the diameter of the spring.
