Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet synchronous rotors, in particular to a permanent magnet synchronous rotor magnetic steel sheet installation device. Background Art

[0002] For the permanent magnet synchronous rotor shaft embedded with magnetic steel sheets, the magnetic steel sheets as permanent magnets need to be placed one by one in the rotor core at a fixed position. However, the clearance between the magnetic steel sheets and the installation holes is very strict, mainly to prevent the movement of the magnetic steel body in the core from interfering with the rotating main shaft. At the same time, the magnetic steel sheets themselves have very strong magnetic adsorption characteristics, which will adsorb the rotor core during installation, causing trouble for its installation. Therefore, any magnetic steel sheet that is not installed in place may need to be re-pushed out to reposition and adjust the magnetic steel. Sometimes, the force of adsorbing the rotor core is too strong, and the rotor core is torn apart in the process of prying the magnetic steel sheets apart, causing damage to the rotor core. There are also adjacent magnetic steel sheets that often experience adsorption collisions due to improper operation, which causes the brittle cracking of the magnetic steel sheets. In addition, due to the size of the magnetic steel sheets, the installation of the magnetic steel sheets requires manual intervention and adjustment, and the strong adsorption force makes the operation extremely inconvenient. Summary of the invention
