PROBLEM TO BE SOLVED: To solve the problem of requiring a large-scale disassembling device so as to prevent a rotor from being adsorbed to a stator with strong magnetic force of a permanent magnet because of there is the risk that the strong magnetic force of the permanent magnet inserted into the rotor adsorbs the rotor to the stator to prevent the rotor from being extracted even though the rotor has to be extracted from a stator frame in order to replace a bearing.SOLUTION: A joining shaft is fixed to an end part of a rotating shaft part of a rotary electric machine, a first holder for supporting the joining shaft is fixed to a bearing bracket to remove a bearing assembly from the bearing bracket, a second holder for supporting the rotating shaft with the bearing assembly removed is then fixed to the bearing bracket to remove the bearing assembly and the first holder, and after that a new bearing assembly is inserted between the bearing bracket and the rotating shaft. |
