In this paper, the authors present a novel construction of an automatic balancing device applicable to balancing shafts working in a heavily polluted environment. The novelty of the presented system lies in the fact that its utilization requires no changes to be made in the already existing shafts. Also, the system is capable of working during the operation of the balanced shaft, so there is no need to stop it. The propulsion system is based on eddy current braking, therefore no wires need to be used in the device. During the development process of the system, three iterations of the device were created. Each iteration is presented, described, and discussed. The advantages and drawbacks of each version are pointed out and explained thoroughly. The correctness of the design was verified by the created devices that were assembled and fixed on shafts to prove the design assumptions.

The paper deals with autimatic balancing of rotating systems during operation. After discussion of existing techniques the novel concepts of balancing mechanisms are presented. The proposed method are easy to apply to various rotating devices, with no need of machine construction modification. Next basics of active balancing control algorithms are presented, and designed detection and correction algorithms are discussed. After descriptions of mechanisms, measurement and control algorithms, simulation and experimental results are presented. The paper ands some conclusions about presented active balancing mechanisms and further works directions are presented.

A theory of two-plane automatic balancing of rigid rotors is presented. For a rotor with two pairs of compensation balls or rollers the stability of compensation phasing is analysed by employing the method of direct separation of motion. The results are confirmed by computer simulation based on the complete equations of motion linearised in the vibrational co-ordinates.
