The main challenge faced at developing rotary machines with variable imbalance is the task of their vibroactivity reduction. An effective method of balancing rotor machines at operation, i.e. without stopping is passive automatic balancing due to free movement of fluid. In the current research the of phenomenon self-balancing of a rotor with the help of fluid media moving in partly filled by it cavity chambers, with that function as passive regulators which need no energy supply and control system is analyzed. Performance of passive fluid self-balancing device when its rotor is passing resonance is presented. The results of theoretical research are verified by experiments.
