摘要:
An imbalance correction method for correcting the imbalance of a rotor measures the vibration state of the rotor before temporary correction and the vibration state of the rotor after the temporary correction in a plurality of rotational speeds in order to make vibration values below the standard. An aggregation range of the tips of correction vectors for obtaining a vibration value which satisfies a vibration standard is calculated from vibration vectors in the rotational speeds. A real correction vector is selected from correction vectors having the tips in a region in which the aggregation ranges calculated for each of the rotational speeds overlap one another among a plurality of the correction vectors. A real correction amount and a real correction phase are set based on the real correction vector. The imbalance of the rotor is corrected based on the real correction amount and the real correction phase.
