Abstract: A bent rotor straightening method using low-frequency induction heating and a bent rotor straightening apparatus using the method are proposed. The bent rotor straightening method using low-frequency induction heating according to an embodiment of the present invention includes: calculating a heating speed when a first target temperature for correcting bending of a rotor using low-frequency induction heating is set; maintaining the first target temperature for a heating time determined on the basis of a diameter of the rotor when the first target temperature is reached, when performing primary thermal correction at the heating speed; checking whether a bending amount of the rotor reaches a predetermined critical value in accordance the result of performing the primary thermal correction; and finishing correction of bending of the rotor in accordance with the result of checking the bending amount of the rotor.
