Improved Motor Efficiency
By incorporating advanced design technologies such as thin silicon steel sheets, high-permeability materials, and air-gap flux density sinusoidization, motor efficiency is significantly improved, achieving a peak efficiency of over 97% and maintaining system efficiency above 85% in more than 90% of the operating range.
Better NVH Performance
Optimized rotor segmentation, skewed poles, and auxiliary slots at the rotor edge effectively reduce noise, keeping no-load noise across the full speed range below 72 dB(A), providing a strong competitive advantage in the industry.
Enhanced Cooling System
A dual-helical cooling channel improves heat dissipation and stability while maintaining optimal water resistance and pressure balance.
IP68 Protection
A flange-based mud and water protection structure prevents contaminants from entering the motor, ensuring IP68 protection and enhanced reliability.
Optimized Junction Box
The junction box features a stamped metal and vulcanized rubber process, improving production efficiency, reducing material costs, and enhancing resistance to temperature fluctuations and condensation.
