Next, a hole is formed near the radial edge of the position of the center of gravity with respect to the center of rotation along the axial direction of the rotor, thereby reducing the weight of a part of the rotor. For this reason, the position of the center of gravity moves in the direction of the center of rotation. The rotor is again rotated to measure the position of the center of gravity, and if necessary, a hole is again formed in the rotor, and the position of the center of gravity is further moved. The above steps are repeated until the rotation balance of the rotor becomes good.
