The Working Principle And Concept Of An AC Fan For Heat Dissipation

Concept of AC fan:
AC fans belong to the category of AC cooling fans, which input AC power. Generally, AC voltages include: 100V, 110V, 120V, 220V, 230V, 240V, 115V, 230V, 380V.
The AC fan power cord does not distinguish between positive and negative, and the color is the same, so it is convenient to power on without paying attention to which line needs to be connected to which interface.
Working principle of AC fan:
The voltage of the power supply will vary positively and negatively, and it must rely on circuit control to rotate the two sets of coils in order to generate different magnetic fields. The AC fan has a fixed power frequency, so the speed of magnetic pole change generated by the silicon steel sheet is determined by the power frequency. The higher the frequency, the faster the magnetic field switching speed, and theoretically, the faster the speed, just like the principle of DC fan with more poles and faster speed. However, the frequency cannot be too fast, as too fast will cause activation difficulties.
