AI Technical Summary

Problems solved by technology

When the rotor is assembled, the assembly gap between the magnetic steel and the rotor magnetic steel groove is only about 0.1 mm. When the magnetic steel is close to the rotor core, the strong adsorption force will directly adsorb the magnetic steel to the iron core and it is difficult to fit into the groove; Once adsorbed, it is difficult to separate, and the assembly is extremely difficult and has certain dangers.
[0004] (2) If there is no strong and accurate guidance guarantee for the rotor during final assembly, the stator and rotor will be adsorbed and locked by strong magnetic force, making it difficult to separate, resulting in failure of final assembly

Embodiment Construction

[0029] A manufacturing process of a 22KW permanent magnet synchronous motor. The process includes the following parts: a magnetic steel assembly process of a rotor, an assembly process, a quenching process, a casting process, and an offline process.

[0030] The magnetic steel assembly process steps of the rotor are as follows:

[0031] (1) To ensure the accuracy of assembly, design tooling fixtures;

[0032] (2) Carry out magnetic steel separation, polarity identification check, and magnetic flux relative value check to ensure that the magnetic flux of each pole is equal after assembly. At the same time, perform visual inspection to see if there is any damage. Each motor should be equipped with magnets of the same batch number to ensure Electromagnetic performance of the motor;

[0033] (3) Preparation of the work site: surround the rotor assembly work site with non-magnetic guardrails and give clear warnings in eye-catching locations; clean the work site and clean up all corners of ...

Description

Technical field [0001] The invention belongs to the technical field of electric motors, and specifically relates to a manufacturing process of a 22KW permanent magnet synchronous motor. Background technique [0002] In addition to the general manufacturing processes (such as mechanical, thermal, and electric clamp processes), there are several key processes in the manufacture of permanent magnet motors: [0003] (1) Due to the extremely strong adsorption force of the magnetic steel, it is easy to adsorb when it is close to ferromagnetic materials (such as iron cores, rotating shafts, etc.). When the rotor is assembled, the assembly gap between the magnet and the rotor magnet slot is only about 0.1 mm. When the magnet is close to the rotor core, the extremely strong adsorption force directly adsorbs the magnet on the core and it is difficult to fit into the slot; Once adsorbed, it is difficult to separate again, and assembly is extremely difficult and has a certain degree of danger...
