Vibrations mostly caused by mass-unbalance reduce the reliability, the operational safety and the life cycle of high speed rotors. This leads to costly outages and unscheduled maintenances. Commonly used offline balancing processes are very expensive for the machine user. To reduce these costs and to realize an uninterrupted control of the balancing states during operation, a complete automatic balancing strategy is proposed. It is based on the combination of the active magnetic bearings, the active balancing devices, and the drive motor and is applied to a flexible low pressure shaft of a helicopter engine test rig. Experimental results validate the efficiency of the proposed strategy.
