220V Cooling Fan works

"220V Cooling Fan" driven by AC power, voltage alternating positive and negative, do not rely on control circuit, generating a magnetic field. Power fixed frequency, pole change speed silicon produced is determined by the power frequency, switching frequency, the higher the magnetic field, the faster, the faster the speed will theoretically. However, the frequency can not be too fast, too fast will cause difficulty in starting. Conductor by the current, generates a magnetic field, when the conductor is placed in another field, will produce suction or repulsion, causing objects to move. In the "220V Cooling Fan" fan inside, surrounded by silicon rubber magnets, two coils wound around the axis part and a Hall sensor component as two synchronous detection device controls a group of circuit which makes the winding axis set of coils work in rotation. Steel have different magnetic poles, the magnetic pole and the repulsive force absorbing rubber magnet. When the suction fan of static friction is greater than the repulsion, the natural rotation of the blades. Since the Hall sensor component provides a synchronization signal, "220V Cooling Fan" fan was able to continue to operate.
