Highly reliable, low-cost nine-phase asynchronous electric drive system for commercial vehicles

To meet the demands for high reliability and low cost in commercial vehicle electric drive systems, we have pioneered the development of a software-defined intelligent multi-phase electric drive system. This approach uses intelligent software to dynamically adjust and optimize the motor's internal architecture, resulting in a multi-phase electric drive system that offers high energy efficiency, high power density, enhanced safety, superior reliability, and lower costs. Compared to conventional three-phase systems, this solution achieves a 50% increase in torque density while reducing material costs by approximately 30%.

Nine-phase asynchronous three-in-one electric drive system

To address the key challenges of traditional three-phase asynchronous electric drive systems—low power density and poor efficiency—the company has pioneered software-driven dynamic motor configuration technology. By employing control algorithms to dynamically adjust the internal magnetic field structure, this technology enables variable pole and phase configurations with full-condition adaptive switching: activating multi-pole configurations for enhanced torque under low-speed heavy loads, and automatically reducing pole count to minimize losses during high-speed light loads. These innovations have improved overall system efficiency by over 8% and power density by 30%.

Seven-phase permanent magnet synchronous two-in-one drive system

To meet the requirements for high efficiency, reliability, comfort, safety, and cost-effectiveness in electric drive axle systems for commercial vehicles with 3.5T or lower engines, an integrated motor-electronic control design is adopted, resulting in a compact size and lightweight construction that reduces overall vehicle weight and lowers costs for wiring harnesses, brackets, and piping. The platform employs proprietary seven-phase permanent magnet motor technology with torque pulsation below 1.2%. Through optimized design combined with harmonic injection, power density is enhanced while NVH performance is improved, significantly boosting driving and riding comfort.
