220V Cooling Fan mechanical wear small

"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. 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 of the top support, so that a the entire rotor vacant. With the traditional ball bearing, oil bearing compared, "220V Cooling Fan" there is no mechanical contact magnetic bearings, rotors can run to a high speed, with mechanical wear small, low energy consumption, low noise, long life, no lubrication, no oil pollution, etc., especially for high-speed, vacuum, clean, and other special environment. "220V Cooling Fan" maglev in fact only an auxiliary function, not form independent bearing, the specific application forms have with other bearings, such as magnetic levitation ball bearing, magnetic oil bearing, magnetic bearings, etc. vaporization.
