"220V Cooling Fan" The principle is that the magnetic flux lines and the maglev line perpendicular to the axis of the core with the magnetic lines are parallel, so the weight of the rotor is fixed on the running track, use is almost no load spool core to the opposite maglev line direction roof support, let into the entire rotor vacant. Changed the way ball bearing friction, rolling friction, this approach is more effective in reducing the friction between the bearing surface phenomenon, effectively increasing the "220V Cooling Fan" bearing life, and therefore the use of the radiator life expectancy. The disadvantage is that the process brings more complex, resulting in cost increase, it also brings higher operating noise. "220V Cooling Fan" in addition to a bearing we have to mention that the main magnetic bearing mute. The use of magnetic force of the magnetic bearing rotor is suspended in the air, so that there is no mechanical contact between the rotor and the stator.
