Abstract
A magnetic bearing which would reduce a leakage magnetic flux to be generated between teeth is provided. A predetermined one of its teeth (24) is configured so that a pitch (P1) between the predetermined tooth (24) and one of two adjacent teeth (24) that are located on clockwise and counterclockwise sides thereof in the circumferential direction is broader than a pitch (P2) between the predetermined tooth (24) and the other tooth (24) and that a magnetic flux flows in the same radial direction through the predetermined tooth (24) and the tooth (24) spaced from the predetermined tooth (24) by the narrower pitch (P1) but flows in two different radial directions through the predetermined tooth (24) and the tooth (24) spaced from the predetermined tooth (24) by the broader pitch (P2).
