The fixed end of the first driving member 30 is installed on the base 1. The driving end of the first driving member 30 is connected to the fixing member 31. The fixing member 31 is configured to fix a magnet to be mounted. The first driving member 30 drives the fixing member 31 to move close to the rotor 4 along the second direction to drive the magnet on the fixing member 31 to approach and be mounted on a mounting surface 40 of the rotor 4.

[0025] It can be seen that the rotor 4 is fixed on the base 1 through the positioning mechanism 2, and then a magnet is mounted on a mounting surface 40 of the rotor 4 through the cooperation of the first driving member 30 and the fixing member 31. This not only significantly improves the accuracy of magnet mounting, effectively avoids the phenomenon of magnet displacement or even falling off due to improper mounting, but also improves the efficiency of magnet mounting, reduces production costs, and brings considerable economic benefits to the enterprise.

After the calibration is completed, the two ends of the rotor 4 are mounted on the two fixed blocks 20 through the two disassembly blocks 21 to complete the installation; secondly, a magnetic steel is adsorbed on the adsorption device 311 for adsorption, and at the same time, the clamping blocks 50 located on both sides of the fixing part 31 clamp and fix the adsorbed magnetic steel; then, the adjusting hand wheel 302 is turned to drive the driving rod 300 to slide on the guide rail 61, driving the fixing part 31 to move, until the adsorbed magnetic steel is approached and mounted on a mounting surface 40 of the rotor 4, ensuring that the rotor 4 and the magnetic steel are aligned for mounting. After mounting, the adjusting hand wheel 302 is turned to drive the fixing part 31 to return to its position; finally, the disassembly block 21 is disassembled and the angle of the rotor 4 is adjusted and fixed, and the next mounting surface 40 is mounted, and the above operation is repeated until all mounting surfaces 40 are mounted.
