Title:
【発明の名称】磁気軸受装置
Document Type and Number:
Japanese Patent JP3315428
Kind Code:
B2
Abstract:
A radial magnetic bearing apparatus suspends a rotating shaft and stably operates at a level exceeding a bending intrinsic vibration value of the rotating shaft by controlling magnetic forces generated by control coils wound around control magnetic poles. Grooves are provided on the surface of each control magnetic pole facing the rotating shaft, and sensor coils are wound to pass through the grooves in order to detect the position of the rotating shaft in the radial direction. A part of each control magnetic pole may be used as magnetic poles of an inductance-type displacement sensor.
