PROBLEM TO BE SOLVED: To provide a system for correcting rotation balance which performs corrective working of a correcting object part with improved accuracy. SOLUTION: The system includes a magnetometric sensor which is installed opposite to the shaft end face of a rotating shaft magnetized to be bisected into an N pole and an S pole, an acceleration sensor which is installed at a rotatory support supporting a high-speed rotation body so that it rotates at a high speed, a balance operation processing part which calculates the amount of correction and the angle of correction of the correcting object part, based on output signals of the magnetometric sensor and the acceleration sensor, a balance correction working part which performs the corrective working of the correcting object part, based on the amount of correction, after the angle of rotation of the rotating shaft is positioned based on the angle of correction, and a reference signal generating part which generates an origin reference signal to be an origin reference for positioning. The balance operation processing part determines a phase shift amount between the output signal of the magnetometric sensor and the origin reference signal, while the balance correction working part performs positioning of the angle of rotation of the rotating shaft, based on the angle of correction and the phase shift amount.
