Concept of AC fan:
The AC fan belongs to the AC cooling fan, which inputs AC power. The general AC voltages are: 100V, 110V, 120V, 220V, 230V, 240V, 115V, 230V, 380V.
The AC fan power cord is of the same color, regardless of positive or negative, so it is convenient to power on. It is not necessary to pay attention to which line is connected to which interface.
Working principle of AC fan:
The power supply voltage will change positively and negatively, and it must rely on circuit control to make two groups of coils work in turn to produce different magnetic fields. Because the power frequency of AC fan is fixed, the speed of magnetic pole change generated by silicon steel sheet is determined by the power frequency. The higher the frequency is, the faster the magnetic field switching speed will be. Theoretically, the faster the speed will be, just like the principle that the more poles the DC fan has, the faster the speed will be. However, the frequency cannot be too fast, and too fast will cause difficulty in activation.
