In the "220V Cooling Fan" internal blades, attached to a pre-filled with rubber magnet magnetic it. Surrounded by silicon, axial part of the winding two coils and a Hall sensor component as a synchronous detection device, controls a group of circuit which makes two sets of coils wound around the axis of rotation job. Silicon generate different magnetic poles, the magnetic pole and the repulsive force absorbing rubber magnet. When the suction repulsion is greater than the "220V Cooling Fan" of static friction, the blades rotate naturally. Since the Hall sensor component provides a synchronization signal, the fan was able to continue to operate, as its direction of rotation, right-hand rule to follow Fleming decision. In practical applications, the nominal maximum wind value, not the actual "220V Cooling Fan" air supply fins obtained air volume, it does not mean strong ventilation capacity.
