AC fan operating principle-technical support-Shenzhen Fu XING Yang Motor Co: the difference between DC and AC fan fan: the former power to AC, alternating positive and negative supply voltage, unlike fixed DC fan power supply voltage and must rely on a circuit, making two turns of the coil can produce different magnetic fields. AC fan for a power supply frequency is fixed, so whizzer pole change speed, determined by the frequency and frequency the higher the magnetic field switch faster, theoretically faster speed, like DC fans the principle of number of Poles more speed more quickly. However, the frequency is not too fast, too fast will cause difficult starting.
