Claims (1)

[Scope of Claim for Utility Model Registration] (1) Rail; A stator pedestal having a guide mechanism for moving the stator of an electric motor perpendicular to the direction of the rail, and a mechanism for raising and lowering the stator cradle and moving the stator on the rail. A movable trolley for the stator pedestal that runs and stops; moves on the same circumference around the rotor shaft of the electric motor, and pushes out the puller and rotor shaft that supports the coupling attached to the rotor at at least three points. A disassembly and assembly device for an electric motor, comprising: a fixed stand for removing a coupler having a support rod; and a coupler carrier that carries the coupler and moves up and down, travels on a rail, and stops. (2) Rail; A tailstock that has a rotor holding shaft that holds the rotor and runs and stops on the rail; A stator pedestal that has a guide mechanism that moves the motor stator perpendicular to the direction of the rail; A moving trolley for a stator pedestal that has a mechanism for raising and lowering the stator pedestal and travels and stops on a rail. A disassembling and assembling device for an electric motor, comprising: a fixed base for loading and unloading a rotor having a chuck mechanism for holding the rotor at a point; and a coupling carrier that carries the rotor and moves up and down, travels on a rail, and stops.
