Abstract
Air-bearing fan includes a dust-proof cover, a fan blade structure, a magnet, a stator, a sleeve, an electronic circuit board, a housing and a thrust disk. While the fan blade structure is rotating, air can be induced into a ring-shaped gap so that an air-bearing is formed. And, air is also induced into a thrust gap and forms a thrust bearing. Therefore, this invention significantly reduces the noise and increases the fan's rotating speed, fan capacity and life.
