What is the reason why the cooling fan in the air purifier does not rotate?

The cooling fan installed in the air purifier rotates and does not rotate. What is going on? There are only two cases, that is, the quality of the fan itself, or the insufficient anti-shock ability. For example, the power design is too high. The temperature keeps rising for a long time, and finally it burns. For example, the voltage of the purifier is a little higher than the rated voltage of the cooling fan, causing the cooling fan chip to burn. Normally, the working voltage of the cooling fan The range should ensure that there is no problem within +/-10% of the rated voltage. The most easily overlooked is the second type. The static voltage interferes with the cooling fan. It is also common for the static voltage in the air purifier to reach tens of thousands of volts. , I just watched the fan spinning and turning, and then turning it on again, but it couldn't turn up again. In this case, the chip of the cooling fan was basically destroyed. The cooling fan manufacturer has rich experience in the anti-interference technology of the cooling fan, and can well shield the interference of static electricity.
