<p>A noncontact magnetic bearing is disclosed, in which cylindrical magnetic members (11, 12) magnetized axially thereof, slightly different in radius and different in length are disposed in opposite relation to each other with their magnetic poles of reverse polarities displaced vertically relative to each other. Either one of the inner cylindrical magnetic member (11) and the outer cylindrical magnetic member (12) can be used as a shaft, and consequently, the other is fixed to a support member. The inner cylindrical magnetic member (11) and the other cylindrical magnetic member (12) are held at a stable and mutual-noncontact state to provide the noncontact magnetic bearing.</p> |
