[0026] The implementation principle of this embodiment is:

[0027] When the equipment is powered on, the stator winding device starts to work. The stator winding device includes a short-circuit ring assembly and a winding frame structure 5, which are isolated by a protective plate 19. The protective plate 19 is a rectangular planar structure, and the surface is provided with nail-shaped protrusions 18, which are perpendicular to the plate surface, enhancing the strength and rigidity of the protective plate 19, preventing the short-circuit ring assembly from directly contacting the winding frame structure 5.

[0028] The stator core 4 in the short-circuit ring assembly is composed of a plurality of silicon steel sheets 16, and the stator core 4 is provided with a plurality of conductive rings 17. When the current passes through the stator winding, the stator core 4 generates a magnetic field. Under the action of the magnetic field, the rotor 13 in the support 2 assembly starts to rotate.
