Description

Technical Field

[0001] The utility model relates to the technical field of motor disassembly, and in particular to a brushless motor disassembly jig. Background Art

[0002] As an important component in modern electronic devices, the performance and stability of brushless motors have a crucial impact on the overall operation of the equipment. However, in actual use, brushless motors may need to be disassembled for maintenance or replacement of parts for various reasons. Existing disassembly and assembly tools have many design deficiencies and cannot meet the requirements of non-destructive disassembly and assembly.

[0003] On the one hand, traditional disassembly and assembly tools often lack accurate positioning, making the motor susceptible to damage or deformation during disassembly and assembly, affecting its service life and performance. On the other hand, some users resort to brute force, such as hitting with heavy objects, to achieve quick disassembly. This practice is not only inefficient but also causes the center of gravity to shift and the force to be unfocused, leading to high scrap rates. This is especially true when removing the brushless motor housing and stator coil assembly, making non-destructive disassembly difficult and complicating repair work. Therefore, we have addressed this issue by proposing a brushless motor disassembly jig. Summary of the Invention
