A method for determining unbalance amounts of a rotor (R). The unbalance amounts of the rotor (R) and the unbalance amounts of a balancing machine are divided. The method comprises the following steps: selecting two planes (I, II) on the rotor (R), measuring the first named unbalance amounts (U11, U21) on the planes (I, II) of the rotor (R) through the balancing machine, the first named unbalance amounts (U11, U21) being vector sums of the unbalance amounts (U1a, U2a) of the balancing machine and the unbalance amounts (U1b, U2b) on the planes (I，II) of the rotor (R), rotating the rotor (R) relative to the balancing machine by a certain angle, moving an angle zero-degree reference point on the rotor (R) by the same angle in the opposite rotation direction of the rotor, and measuring the second named unbalance amounts (U12, U22) of the rotor (R) through the balancing machine, the second named unbalance amounts (U12, U22) being vector sums of the unbalance amounts (U1a, U2a) of the balancing machine and the unbalance amounts (-U1b,-U2b) on the planes (I, II) of the rotor (R) after the rotor (R) is rotated by the certain angle. In the first named unbalance amounts (U11, U21) and the second named unbalance amounts (U12, U22), the unbalance amounts (U1a, U2a) of the balancing machine are the same in size and direction, the unbalance amounts on the planes (I, II) of the motor (R) are the same in size, and the directions are changed by the certain angle. |
