"220V AC Cooling Fan" internal blades, attached to a pre-filled with the magnetic rubber magnets. Surrounded by silicon steel, two sets of coils wound around the axial center portion, and a Hall sensor component as a synchronization detection means for controlling a set of circuits, the circuit of the two sets of coils wound around the axis of rotation of work. "220V AC Cooling Fan" silicon have different poles, the poles with rubber suction magnet repulsion. When the suction fan of repulsion greater than the static friction, the natural rotation of the blades. Due to the Hall sensor component provides a synchronization signal, "220V AC Cooling Fan" fan was able to continue functioning, as its direction of rotation, right-hand rule to follow Fleming decision.
