<P>PROBLEM TO BE SOLVED: To provide a magnetic bearing motor/fan with significantly reduced operating noise of the motor/fan, significantly prolonged operating life time, and significantly reduced production cost. <P>SOLUTION: There are provided a stator structure which comprises a stator base comprising at least a center opening, a first magnetic fixing structure positioned inside the opening, a second magnetic fixing structure positioned around the opening, and a stator magnetic pole positioned above the stator base; and a stator structure which comprises at least one housing that covers from above the side of the stator structure; an axis that extends and protrudes from the housing, before entering the opening; a rotor magnet that encloses the stator magnetic pole; a third magnetic fixing structure, positioned to correspond to the first magnetic fixing structure; and a fourth magnetic fixing structure positioned to correspond to the second magnetic fixing structure. The first magnetic fixing structure attracts the third magnetic fixing structure to each other, and the second magnetic structure attracts the fourth magnetic fixing structure to each other. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
