AI Technical Summary
Technical Problem
Existing brushless motors lack waterproofing in industries such as pool cleaning, sink cleaning, and floor cleaning. This leads to damage to the motor shaft during the potting process of the whole machine's oil seal, affecting efficiency and power loss.
Method used
The stator and rotor structures are sealed with waterproof adhesive. The drive plate, copper wire windings and winding slots are sealed with waterproof adhesive, and combined with permanent magnet rings and rolling bearings, the rotor can operate normally in water and prevent water intrusion.
Benefits of technology
This technology improves the waterproof performance of brushless motors while maintaining operational efficiency, reducing power loss, and enhancing motor stability and lifespan.
