AI Technical Summary

⚠Technical Problem

The existing motors have insufficient sealing when running in water, which makes them unable to achieve long-term stable operation and poses a risk of water leakage.

⚗Method used

The stator employs a dual-sealing structure. First, a primary seal is achieved through the plastic encapsulation of the stator injection molded body. Then, a secondary seal is achieved by covering the stator injection molded body with a plastic-coated outer shell. The connection design of the iron core frame, plastic-coated skeleton, stator injection molded body, and plastic-coated outer shell enhances the sealing performance.

🎯Benefits of technology

It significantly improves the sealing performance of the motor, enabling it to operate stably in water for extended periods, preventing leakage, and ensuring high connection reliability.
