A drive location compensation system determines a deviation between an actual and nominal position of a drive location on a rotor relative to an attachment location on the rotor. The compensation system uses a balancing machine and a sensor that detects when one of the attachment locations passes a known position. Based on the output of the sensor and a known position of a drive spindle of the balancing machine that is coupled to the drive location on the rotor, a relation between the drive spindle and the attachment location is determined. This relationship is compared to a nominal relationship that is based on a calibration standard. The deviation is compensated for during the balancing or the rotor.
