The customer said that the cooling fan vibrates greatly, that is, it jitters greatly during operation, that is, it rotates unevenly. Does this have an impact on the performance of the cooling fan? Is there a way to eliminate the vibration?
First of all, there is no jitter at all. It is impossible to not vibrate. As long as the cooling fan is rotating, it will produce a certain degree of vibration. Of course, the lower the jitter, the better the performance of the cooling fan.
First, the vibration is small, the resonance produced by the installation on the product is smaller, and the sound is quieter
Second, the vibration is small, the bearing damage to the cooling fan is small, and the service life is longer.
To reduce the jitter of the cooling fan, firstly, the precision of the mold design is required. The balance of the fan blade is inherently good when the fan blade is injection molded, and then the consistency of the magnetic stripe of the motor shell, because these two accessories are also installed in the fan blade to run together. After the innate precision of the accessories is done, if you want to better, you can use a balance machine to fill the soil for balance, but the manual repair is high.
