ABSTRACT:
An improved unbalance compensator control in which the distribution of balance mass fluid is controlled by selective activation of thermal devices creating thermal differentials and ensuing balance mass fluid re-distribution for balance correction, and in which electrical power for the thermal devices is transmitted across an air gap separating stationary and rotating portions by means of the selective energizing of primary coils each of which has a corresponding confronting secondary coil associated therewith. Different geometries of coils are disclosed. In another embodiment a composite waveform containing power and signal components is conducted to the rotating portion by electro-mechanical contact arrangements at opposite axial ends of the machine on which the unbalance compensator is mounted.
