The facing end surfaces of the two iron core limiting rings 2 are evenly coated with glue, and the two iron core limiting rings 2 are bonded and fixed to the magnetic steel limiting ring 3 to better limit the magnetic steel.

After installation, the magnetic steel forms a closed magnetic steel ring in the magnetic steel installation groove, and then a magnetic steel limit ring 3 is sleeved on the outside of the magnetic steel ring, and then the iron core 7 and the iron core limit ring 2 at both ends of the limit column 1 of the locking and clamping mechanism are locked to clamp the middle magnetic steel, and finally, after the adhesive hardens, the clamping mechanism is released to complete the assembly of the magnetic steel 6. The present bladeless wind turbine electromagnetic steel assembly process adopts tooling positioning, self-priming fixation of the magnetic steel 6 and adhesive-assisted fixation, and the clamping mechanism is used to clamp and complete the assembly of the bladeless wind turbine electromagnetic steel, which reduces the use of screws, thereby ensuring the overall integrity of the magnetic steel assembly, improving the service life of the magnetic steel assembly, and then improving the service life of the bladeless wind turbine generator and ensuring the power generation rate of the bladeless wind turbine generator.
