AI Technical Summary

Technical Problem

In the existing technology, due to the large magnetic attraction between the rotor and the stator, a large external force needs to be applied during disassembly and assembly, which can easily lead to bearing damage or stator coil damage, resulting in the scrapping of the motor.

Method used

A drive motor rotor disassembly and assembly tool is designed, including a first fixed plate and a second fixed plate arranged opposite to each other, a sliding plate slidably mounted on a slide rail, and a top pin driven by a first pushing component and a second pushing component to disassemble and assemble the rotor, ensuring the stability and accuracy of the disassembly and assembly process.

Benefits of technology

It enables rapid assembly and disassembly of the rotor, reduces the complexity and labor intensity of manual operation, lowers the risk of component damage, and ensures the alignment and stability of the assembly and disassembly process.
