1. A balancing device for balancing a rotating body having an axis while in operation by asymmetrical thermal deformation comprisinga. means for sensing the phase and magnitude of unbalance in said rotating body,b. transducing means, connected to said sensing means, for providing a signal representative of the phase and magnitude of said unbalance,c. an energy source for supplying energy pulses to said rotating body for local asymmetric heating to case thermal deformation of the axis of the body without removing or adding any material from or to the body,d. control means, responsive to said transducing means, for controlling said energy source to control the phase and amount of said energy pulses, supplied to said rotating body, andsaid control means controlling said energy source to supply energy pulses to said rotating body at a position opposite said unbalance.
