Abstract: The automatic real time balancing of rotor at working speed by active magnetic actuator is studied. The algorithm of on-line automatic identification and attenuation for unbalance vibration are deduced. The method presented is applied in a rotor system supported by 'ball bearings. The experiment results confirm that the unbalancing vibration of rotor in working rotational frequence is greatly extenuated by using above method and device.
