Abstract
PURPOSE:To derive a correction working extent with high accuracy, by providing the first process for deciding a corrected position and correction working weight in accordance with information regarding initial unbalance, the second process for calculating a position of the center of gravity of a correction working part by said correction working weight, and other process. CONSTITUTION:In the first process of a flow chart, that is to say, an initial unbalance extent input process 15, initial dynamic unbalance weight U1, U6 measured by a dynamic unbalance testing machine is inputted to a computer. Subsequently, in a deciding process 16 of a corrected angle, being the second process, directions of vectors U2, U3 for correcting U1, that is to say, directions theta2, theta3 (unit:degree) of cores to be deleted are decided so as to become theta2<=theta1 <theta3=(theta2+30 deg.)(provided that, theta2=0 deg., 30 deg., 60 deg.,-330 deg.). In this way, solution of the correction working extent for obtaining the dynamic unbalance whose solution has been difficult actually can be obtained with sufficient accuracy for its practical use.
