Abstract

PURPOSE: To get a magnetic bearing which is casy to assemble and large in radial spring constant, by configuring a series of magnets, n in number, opposed through a gap to another series of magnets, n+1 in number, which are being set in the radial direction, different in diameter and magnetized in the axial or radial direction on the contrary.
CONSTITUTION: A magnetic bearing is equipped with a supporting plate 2 with which a rotational unit is connected, magnet 3 on the rotary side, guard ring 4, magnet 5a on the rotational side, fitting plate 6b, etc. A magnet 5c, which is polarized in the same axial direction as the magnet 5a and different in diameter from the magnets 5a, 3, is set inside in the radial direction on the same plane with the magnet 5a. The magnetic bearing of this configuration is suitable for high revolution, easy to assemble and improved in anti-vibration performance with an increased radial spring constant.
