AI Technical Summary

Technical Problem

When the winding coils of existing brushless coreless motors are installed in the coreless cup by bonding, the installation is difficult and it is hard to ensure uniform distribution, which affects the inductance performance of the coils.

Method used

The coil is fixed to the inner wall of the iron core by using fasteners (such as fixing blocks). The coil is fixed by fasteners to ensure its uniform distribution, reduce assembly difficulty and improve inductance consistency.

Benefits of technology

This effectively reduces assembly difficulty, ensures uniform coil distribution, and improves the inductance consistency and product quality of stator components.
