However, due to the large magnetic force between the stator assembly, the permanent magnet rotor assembly, and the ferromagnetic material, it is difficult to assemble the permanent magnet rotor assembly
In the prior art, since the assembly of the permanent magnet rotor assembly is performed by the operator by manually holding the permanent magnet rotor assembly, the operator mainly relies on the operator to manually overcome the magnetic force; during the assembly process, due to the action of the magnetic force, the permanent magnets often occur between each other. , and the collision between the permanent magnet and the magnetic motor housing or other parts, resulting in damage to the permanent magnet, broken and damaged coils of the stator assembly, or pinching the operator, which directly leads to a high scrap rate of the permanent magnet and an unsafe assembly process , high manufacturing costs and other issues

The invention discloses a permanent magnet motor stator assembly, and a permanent magnet rotor assembly assembling tool and an installation method, and relates to the permanent magnet motor assemblingfield. The tool comprises a disc-shaped guide block. The guide block is provided with a shaft hole through which a motor shaft penetrates; a connecting groove is formed in the surface of the rear endof the guide block; a plurality of connecting holes penetrating through the connecting groove are formed in the front end surface of the guide block; and chamfers are arranged along the outer diameter of the front end of the guide block, steps are arranged at the corresponding positions of the outer circles of the left side and the right side of the guide block, fixing holes are formed in the guide block along the surfaces of the steps, and the guide block is broken along the center line of the guide block to form an upper half portion and a lower half portion which penetrate through the fixing holes through bolts and are fixedly connected with each other. Due to the arrangement of the guide block, the permanent magnet rotor assembly is always located in the center of the stator assemblyduring installation, the permanent magnet rotor assembly and the stator assembly cannot collide with each other, an assembly yield of the permanent magnet motor is improved, production and manufacturing cost is reduced, meanwhile, labor intensity of operators is relieved, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of permanent magnet motor assembly, in particular to a permanent magnet motor stator assembly and permanent magnet rotor assembly assembly tooling and an installation method. Background technique [0002] Compared with traditional motors, permanent magnet motors have the advantages of simple structure and reliable performance. However, due to the large magnetic force between the stator assembly, the permanent magnet rotor assembly and the ferromagnetic material, it is difficult to assemble the permanent magnet rotor assembly. In the prior art, since the assembly of the permanent magnet rotor assembly is performed by the operator by manually holding the permanent magnet rotor assembly, the operator mainly relies on the operator to manually overcome the magnetic force; during the assembly process, due to the action of the magnetic force, the permanent magnets often occur between each other. , and the collision between ...
