Given limitations on potential locations, weight sizes and amount of weights all possible applied unbalance magnitudes and angles are calculated after determining the initial unbalance magnitude and angle of the rotor this result is vector summed with all possible applied unbalances. The lowest resultant magnitude is determined, independent of the angle. The corresponding weight combination produces the lowest possible residual unbalance within the constraints.

A method of balancing a rotor having a finite number of potential weight locations, using preselected class weights and limitation on the amount of weights to be used: rotating the rotor; measuring the true initial unbalance magnitude and angle of the rotor unbalance; calculating the applied unbalance magnitude and angle for each possible selection of weight classes and weight locations within said limitation; determining a plurality of calculated residual unbalances by vector summing said initial unbalance magnitude and angle with each calculated applied unbalance magnitude and angle; selecting the minimum value of said calculated residual unbalance magnitudes; and installing the weights producing said minimum value at the locations producing said minimum value.
