摘要 |
An active type magnetic bearing system includes magnetic bearings (112, 113) for suspending a rotary body (1) to permit it to rotate about its rotational axis. A control system (118) supplies the magnetic bearings (112, 113) with signals to control the radial position of the rotary body, and comprises displacement detecting circuits (2, 3, 13, 14) for detecting any displacement of the radial position of the rotary body (1) and a control circuit (118) for producing a control signal which serves to suppress any unstable vibration of the rotary body. |
