Introduction 220V AC Cooling Fan blades

"220V AC Cooling Fan" Magnetic bearings use magnetic force of the rotor is suspended in the air, so there is no mechanical contact between the rotor and the stator. The principle is that the magnetic flux lines and maglev line perpendicular to, the axis and the maglev line are parallel, so weight of the rotor is fixed on the running track, the use of almost no load spool core to the opposite maglev line direction of the top support, so that a the entire rotor vacant.
