Abstract

PURPOSE: To enhance a magnetic force generated in a magnetic bearing of a same size by heightening a magnetic flux density in a constitution in which a material of highly saturated magnetic flux density is employed in an outside circumference core and at least a slit is provided in the core.
CONSTITUTION: Cylindrical outside circumference cores 130 and 170 constituting an outside circumference magnetic path of a magnetic bearing which is composed of a stator bearing 110, a rotor bearing 150 and a coil 4 are made of a material of highly saturated magnetic flux density such as permalloy, silicon steel and pure iron, and in the X-Y axes direction at least a slit 200 is provided in the cores to prevent an eddy current from being generated by an AC magnetic flux. This method can heighten a magnetic flux and provide a magnetic bearing of which magnetic force is improved several times more than that of a conventional one of a same size.
