摘要：
In a method for removing a crack in an electromechanical rotor, a through-hole penetrating from a side of one of slots adjacent to each other via a rotor core portion to a side of the other slot is formed to include a crack in the rotor core portion occurring to a contact surface with a wedge, in an electromechanical rotor including a plurality of slots formed in an axial direction in an outer peripheral surface of the rotor core portion, a coil housed in the slot, a wedge inserted in an upper portion of the slot to be arranged in the axial direction and holding the coil in the slot, and the crack is removed.
