"Micro Cooling Fan" in the works above AC DC fans and fan is not the same. Conductor through the current generates a magnetic field, if the conductor is placed in a magnetic field to another, it will produce suction or repulsion, causing objects to move. In "Micro Cooling Fan" fan inside, surrounded by silicon rubber magnets, two coils wound around the axial center portion, and a Hall sensor component as two synchronization detection means controls a set of circuit which makes winding axis group work coil turns. Steel produce different magnetic poles, the magnet pole and the rubber suction repulsion. When the suction repulsion is greater than the "Micro Cooling Fan" of static friction, the blades rotate naturally. Due to the Hall sensor component provides a synchronization signal, the fan was able to continue running.
