摘要：
A method for repairing a crack in an electromechanical rotor (10), including forming a plurality of slots (12) on a periphery of a core portion (11) of an electromechanical rotor (10) along an axial direction thereof; inserting coils into the slots (12), respectively; forming a plurality of wedges for maintaining the coils in the slots (12), respectively; and forming a cut hole (20) at the core portion (11) from an outer surface of the core portion (11) so as to remove at least a deeper area of a crack created at the core portion (11) at a contacting surface between the corresponding wedge and the corresponding slot (12).
