    Tips: How DC cooling fans work?

    The core components of a DC cooling fan are a stator and a rotor. Through Ampere's right-hand rule, we know that when a conductor passes a current, a magnetic field is generated around it. If this conductor is placed in another fixed magnetic field, suction or repulsion will be generated, causing the object to move. Inside the fan blade of the DC fan, a rubber magnet filled with magnetism is attached in advance. Around the silicon steel sheet, the axis portion is wound with two sets of coils, and the Hall induction component is used as a synchronous detection device to control a set of circuits. This circuit makes the two sets of coils around the axis work in turn, so that the silicon steel sheet generates different magnetic poles. This magnetic pole produces a repulsive force with the rubber magnet. When the repulsive force is greater than the static friction of the lice fan, the fan leaves rotate naturally. Because the Hall sensor component provides a synchronization signal, the fan blade can continue to run. As for the direction of its operation, it can be determined by Fleming's right-hand rule.
