Abstract
On the stationary side of a radial bearing constructed of a plurality of magnetic poles, the magnetic poles are formed into a shape such that the magnetic flux density distribution formed between the inner surfaces of these magnetic poles and a rotor located on the rotating side of the radial bearing has a distribution inclined from the magnetic pole end portion to the magnetic pole center portion. With this arrangement, the rate of change in magnetic flux density during the shift of the rotor from a magnetic pole to the adjacent magnetic pole is reduced, thereby reducing the eddy current loss and heat generation.
