AI Technical Summary
The existing motor stator frame adopts a split structure, which results in long production cycle, high cost, easy loosening, poor versatility, and difficulty in adapting to stator cores of different sizes or types.
An integrated molded bracket is directly wrapped around the stator core through injection molding, simplifying the assembly process, improving structural strength and stability, and is suitable for stator cores of different thicknesses.
It improves the production efficiency and stability of motors, reduces the risk of loosening, is suitable for high-vibration environments, reduces manufacturing costs, and increases versatility.
