The different bearing mini air cooling fan

"Mini Air Cooling Fan" Bearing change the way of bearing friction, rolling friction, this approach is more effective in reducing the friction between the bearing surface phenomenon, effectively increasing the fan bearing life, and therefore the radiator longer life. The disadvantage is that the process brings more complex, resulting in cost increase, it also brings higher operating noise. There is also 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, the axis "Mini Air Cooling Fan" use almost no load to the opposite maglev line direction of the top support, let into the entire rotor vacant. Compared with conventional ball bearings, oil bearing, magnetic bearing no mechanical contact with the rotor can run to a high speed, with mechanical wear small, low energy consumption, low noise, long life, no lubrication, no oil pollution, etc. especially suitable for high-speed, vacuum, clean, and other special environment. Maglev in fact only an auxiliary function, not form independent bearing, "Mini Air Cooling Fan" specific application forms have with other bearings, such as magnetic levitation + ball bearing, magnetic + oil bearing, magnetic bearings, etc.
