Abstract
Provided is a magnetic bearing device capable of facilitating manufacture of the magnetic bearing device and improving precision in production thereof while maintaining eddy current reducing effects. The magnetic bearing devicesupporting a rotating shaftwith a magnetic force includes a plurality of magnetic polesarranged in the circumferential direction of the rotating shaft. Each magnetic poleincludes an inner end surfacefacing the outer surface of the rotating shaft in proximity thereto. The magnetic poles which are adjacent to each other in the circumferential direction respectively extend in the axial directions of the magnetic polesto the inner end surfacesof the magnetic poles so as to virtually interfere with each other in the vicinity of the outer surface of the rotating shaft. The virtual interfering portionsof both the magnetic polescapable of interfering with each other are removed by cutting.
