Abstract
A rotation control system for preventing unbalance vibrations and synchronous disturbance vibrations of a rotary member suspended by a magnetic bearing. This system includes a vibration detector which detects radial vibration of the rotary member. On the basis of the detected radial vibration, a compensating signal which has the same amplitude and cycle as the vibration component having the rotational frequency is generated. The difference between the detected vibration and the compensating signal is obtained and used for controlling the radial position of the magnetic bearing.
