ABSTRACT:
A circuit and process for eliminating unbalances on a rotor which permits equalization of unbalance only in constructionally predetermined equalization planes and component angles in which conventionally produced balance signals indicating the amounts and angles of unbalance are rectified and applied to an arithmetic circuit which produces output signals indicating the amounts of unbalance in equalization planes and, where balance in a given equalization plane is not possible, the amount of unbalance in a substitute plane. To permit balancing of different type workpieces having different dimensions, potentiometers are connected to the arithmetic circuit and to a longitudinal positioning circuit for applying signals indicating locations of the planes.
