Abstract: A high-speed rotor system can be very sensitive to rotating mass unbalance which is harmful to rotating machinery. Therefore, many kinds of balancing device were created to reduce vibration in high-speed rotor system. In an electromagnetic driven balancing system, rotor unbalance is online identified and calculated by electromagnetic compensator, and then the balancing discs will be moved to the best compensating positions and the unbalance can be suppressed or eliminated. Unfortunately, industrial application using auto-balancing technology is limited by its long transition time and transient vibration enhancement. To solve these deficiencies on compensator movement control, a bi-disc freely rotation strategy was established and the solutions of two special cases were also given out. A test rig of electromagnetic driven bi-disc free rotation rotor auto-balancing system was established. Experiments using the new control strategy on this rig showed that the compensa!
tor could be moved faster and more accurate. At the meantime, the balancing time was reduced, and more important, enhancement on transient vibration was avoided.
