<p>PROBLEM TO BE SOLVED: To employ an optimal balance correction system for individual rotors of motor in view point of both correction time and correction accuracy. SOLUTION: Measurements are received from a balance measuring apparatus through a sequencer 20 and selection is made, for the first time, between static correction and dynamic correction (S10, S20) by comparing an even measurement representative of the magnitude of even balance with an even management value Gn. Static correction is selected if a static measurement representative of the magnitude of static balance < a static traverse correction value STn (S30, S40), whereas dynamic correction is selected if the even measurement >=Gn or the static >=STn (S50). When static correction is selected, the static measurement is compared with K-STn and polar coordinate correction is selected it the static measurement <K.STn otherwise component force correction is selected (S60-S80). Furthermore, a decision is made which of plunge cutting or traverse cutting is selected and a finally set correction system is sent back to the sequencer 20 (S90-S120). K is a coefficient of smaller than 1.</p> |
