The high-speed rotating electrons cause the air suspension bearing to generate air buoyancy, usingthe air around the high-speedrotor instead of the lubricating oil, When the blower starts,the rotor firstrotates at a high speed, rotating to more than 6 thousand to10 thousand rotations,compressed airfilmis 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.
