PROBLEM TO BE SOLVED: To provide a rotating-balance correction apparatus which can endure a considerably high-speed rotation, which can be miniaturized easily and which is nearly free of maintenance. SOLUTION: This rotating-balance correction apparatus is provided with rotatable balancing rotors 1. In addition, the apparatus is provided with soft magnetic pole-plate rotors 2 which are fixed to a shaft 6. In addition, the apparatus is provided with magnet rings 31 and magnet rings 32 which surround its outer side. Three rows of salient pole rows 1a, 1b, 1c are provided on the outer circumferential face of the balancing rotors 1. When the magnet rings 31, 32 are moved to the shaft length direction, induction salient poles 22 at the pole plate rotors 2 are magnetized properly. Then, the balancing rotors 1 are turned with reference to the shaft 6. When the balancing rotors 1 in both units 100, 200 are turned so as to offset a static imbalance, a static balance is established around the shaft 6. The rotating members 1, 2 are symmetric with respect to a rotation, the rotating-balance correction apparatus can endure a high-speed rotation, it can be miniaturized easily, and it is nearly free of maintenance because a sliding contact part such as a slip ring or the like is not provided.
