Principle of DC fan
There is a rubber magnet in the fan blade part of the DC micro fan, which is magnetized before working and has magnetism. In addition, the rubber magnet is surrounded by silicon steel sheets, and two sets of coils are wound on the silicon steel sheets. When energized, the four poles of the stator will have a magnetic field. Because the silicon steel sheets are divided into large and small heads, the steering of the DC fan is also It is to turn from the big head to the small head, and use Hall induction IC to control a group of circuits. Using the principle of electromagnetic induction, the IC alternately switches the two sets of coils for power supply. The two magnetic fields use the principle of attraction of the same sex and repulsion of the opposite sex to make the fan run.
