The high-speed rotating electrons cause the air suspension bearing to generate air buoyancy, usingthe air around the high-speed rotor instead of the lubricating oil. When the blower starts,the rotor firstrotates at a high speed, rotating to more than 6 thousand to 10 thousand rotations, compressed air filmis generated between the rotor and the air foil bearing,so that the rotor is suspended. Before the rotor issuspended, there is friction between the rotor and the air foil bearing, so the air suspension blower hasto experience two frictions during the start and stop process. When the take-off speed is reached,the airbearing and shaft are contactless and frictionless.
