[0034] The inside of the limiting plate 28 is provided with a positioning hole; the inside of the positioning hole is fixedly connected with a positioning bolt 29; when the flexible stator body 19 is installed with the strong magnetic field rotor body 20, when the flexible stator body 19 slides to the half position of the strong magnetic field rotor body 20, the workers fix the limiting plate 28 on one side of the flexible stator body 19, at this time, the limiting arc plate will be in contact with the surface of the flexible stator body 19, and the position of the flexible stator body 19 is limited by the limiting arc plate, so as to avoid the rotation of the flexible stator body 19 during the downward sliding process, which affects the installation of the flexible stator body 19 and the strong magnetic field rotor body 20; when the limiting plate 28 is installed on one side of the flexible stator body 19, the sliding of the flexible stator body 19 will rub against the limiting pulley 30, and the downward sliding of the flexible stator body 19 will make the limiting pulley 30 rotate, and the rotation of the limiting pulley 30 will rub against the flexible stator body 19; when the flexible stator body 19 accidentally rotates, the limiting pulley 30 will prevent the rotation of the flexible stator body 19, so as to ensure the normal downward sliding of the flexible stator body 19 and the installation and connection with the strong magnetic field rotor body 20; when the limiting plate 28 is installed on one side of the flexible stator body 19, the workers insert the positioning bolt 29 into the inside of the positioning hole, so as to fix the limiting plate 28 on one side of the flexible stator body 19, and ensure that the limiting pulley 30 can be attached to the surface of the flexible stator body 19, thereby reducing the rotation of the flexible stator body 19 during the installation process.

[0035] Example two

[0036] Please refer to Figure 5 As another embodiment of the present application, the inside of the disassembly push plate 33 in the above-mentioned example one is fixedly connected with a magnet block 34; during work, the workers need to connect the second bearing cable 17 with the first connecting lifting ring 31 before work, the workers push the disassembly push plate 33, at this time, the first connecting lifting ring 31 enters the inside of the second connecting lifting ring 32 from the position of the disassembly push plate 33, at this time, the connection of the second connecting lifting ring 32 and the first connecting lifting ring 31 is completed, so that the second bearing cable 17 limits the position of the connecting base plate 18 and the flexible stator body 19, which is convenient for subsequent moving operation; after the first connecting lifting ring 31 is connected with the second connecting lifting ring 32, the magnet block 34 is adsorbed to one end of the second connecting lifting ring 32 through the magnetic attraction force, so as to tightly attach the disassembly push plate 33 to one end of the second connecting lifting ring 32, thereby avoiding the accidental separation of the first connecting lifting ring 31 from the inside of the second connecting lifting ring 32 during work.

[0037] Working principle: when working, the permanent magnet direct drive motor is assembled in the process of the stator and the permanent magnet rotor, the permanent magnet rotor has strong magnetism and will produce very large magnetic attraction with the motor stator. In the process of inserting the rotor into the stator and installing the front and rear end covers, it is difficult to complete the assembly work due to the attraction of the rotor permanent magnet. If forced assembly is adopted, it is easy to cause production quality problems such as damage to the insulation of the stator winding, damage to the bearing, etc. When working, the worker first connects the second load-bearing cable 17 with the connecting base plate 18, and limits the position of the flexible stator body 19 through the cooperation of the second load-bearing cable 17 and the connecting base plate 18. At this time, the electric sliding rail body 1 is started to make the moving block 12 slide. The sliding of the moving block 12 will make the first load-bearing cable 15 slide together. The sliding of the first load-bearing cable 15 will make the rotating disc 16 slide, and the sliding of the rotating disc 16 will make the moving lifting plate 25 slide. The sliding of the moving lifting plate 25 will make the second load-bearing cable 17 and the connecting base plate 18 slide, so as to make the flexible stator body 19 slide together. Then the flexible stator body 19 is moved to the upper side of the strong magnetic field rotor body 20 through the electric sliding rail body 1. The worker lowers the first load-bearing cable 15, so that the flexible stator body 19 is lowered to the top of the strong magnetic field rotor body 20. At this time, the worker detects the flexible stator body 19 and the strong magnetic field rotor body 20 through the magnetic attraction detection equipment 13. After detection, the displacement detection equipment 14 transmits information to the first motor 22. The output of the first motor 22 drives the gear body 23 to rotate. The rotation of the gear body 23 drives the gear block 24 to rotate. The rotation of the gear block 24 drives the moving lifting plate 25 to rotate. The moving lifting plate 25 can rotate at the bottom of the rotating disc 16. The rotation of the moving lifting plate 25 will make the flexible stator body 19 rotate together. The center of the flexible stator body 19 and the center of the strong magnetic field rotor body 20 are adjusted to the concentric state. Then the flexible stator body 19 and the strong magnetic field rotor body 20 are aligned through the cooperation of the magnetic attraction detection equipment 13 and the displacement detection equipment 14. At this time, the worker moves the first load-bearing cable 15 downward, so that the flexible stator body 19 slides downward and is installed on the strong magnetic field rotor body 20. Through the cooperation of the magnetic attraction detection equipment 13 and the displacement detection equipment 14, the center of the flexible stator body 19 and the center of the strong magnetic field rotor body 20 can be adjusted to the concentric state, which is convenient for the connection and installation of the flexible stator body 19 and the strong magnetic field rotor body 20, and the production quality problems such as damage to the insulation of the stator winding and damage to the bearing are avoided.
