AI Technical Summary
Technical Problem
Traditional motor stator structures have gaps or slots when spliced into a ring, which leads to increased noise and vibration, affecting motor performance.
Method used
The low-noise modular motor stator structure is adopted. By setting the end of the arc-shaped pole shoe to seal the groove between two adjacent arc-shaped pole shoes, and axial fixation is achieved by rivets or bolts, the assembly accuracy and stability are ensured.
Benefits of technology
It effectively reduces motor noise and vibration, improves winding efficiency and slot fill factor, simplifies the production process, and enhances the integrity and stability of the stator structure.
