Abstract

PURPOSE: To eliminate vibration by moving a rotor shaft through adjustment of standard magnetic support bearings according to signals corresponding to vibration of a stator or frame of a rotary machine detected.
CONSTITUTION: A rotary machine has a stationary armature 28, a frame 24, vibration detectors 23, 25, position detectors Dx-Dx', Dy-Dky'. Signals detected by the respective detectors are processed together with a signal input of a tachometer converter 40, at an automatic balance processing circuit, and signals detected by the vibration detectors and skynchronization signals 38 are processed at an adaptive signal processor (stator vibration controller). Output signals thereof and an output signal of the automatic balance processing circuit are input to a control circuit, and electromagnetic coils Ex-Ex, Ey-Ey' are controlled. Accordingly, the vibration of rotary machine is eliminated, reliability of operation is enhanced, and generation of wear is reduced.
