220V AC Cooling Fan magnetic induction

"220V AC Cooling Fan" internal blades, attached to a pre-filled with the magnetic rubber magnets. Surrounded by silicon, axial part of the winding two coils and a Hall sensor component as a synchronous detection device, controls a group of circuits, the "220V AC Cooling Fan" circuit two coils wound around the axis of rotation job. Silicon 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 AC Cooling Fan" fan was able to continue to operate, as its running direction, to follow Fleming's right-hand rule decision.
