[0071] S3, after the rotor is clamped and fixed by the clamping mechanism 4, the rotor can also be fixed by the binding device 7, first, the binding frame 702 of the binding device 7 is buckled on the rotor, then the roller 704 is rotated to tighten the roller 704 on the binding belt 703, and the rotor is fixed again by binding the binding belt 703 on the rotor;

[0072] S4, after the rotor is clamped, the height of the clamped rotor can be adjusted by the adjusting mechanism 3 of the clamping positioning device 2, so that the height of the rotor is flush with the motor shell, when adjusting, the driving structure 305 of the adjusting mechanism 3 drives the lead screw 302 to rotate in the sliding rail 1 301, so that the sliding blocks 1 303 are close to each other, then the supporting rod 304 is raised, so that the clamping mechanism 4 is raised, and the clamped rotor is adjusted in height;

[0073] S5, after the adjustment is completed, the vehicle body 1 can be pushed, so that the moving wheels 102 on the vehicle body 101 move along the track 104, and then the rotor is inserted into the motor shell.
