摘要

新能源汽车电机的驱动性能优劣直接关联整车动力与经济表现。当前系统在高速运行效率、宽转速区间扭矩输出以及热量控制方面存在明显短板，这些短板限制了整车性能的进一步提升。针对上述局限，本文从电机电磁构造、逆变器控制策略、热量管理方案及传动协调四个层面开展优化设计。本研究借助电磁场仿真和多物理场耦合分析实现参数精确调校，并且搭建试验平台对方案进行实测验证，结果显示系统最高效率提高了3.2％、高效工作区间拓宽了15%、百公里耗电量减少8.7%、续航里程增加45km，为驱动系统的高性能化探索出一条可行的技术路径。

Abstract

The driving performance of the motor in new energy vehicles is directly related to the overall power and economic performance of the vehicle. The current system has obvious shortcomings in terms of high-speed operation efficiency, torque output over a wide speed range, and heat control. These shortcomings have restricted further breakthroughs and improvements in the overall vehicle performance. In response to the above-mentioned limitations, optimization design is carried out from four aspects: motor electromagnetic structure, inverter control strategy, heat management plan and transmission coordination. By means of electromagnetic field simulation and multi-physics coupling analysis, precise parameter adjustment is achieved, and a test platform is built to verify the scheme through actual measurement. The results show that the system's maximum efficiency has increased by 3.2%, the high-efficiency working range has been expanded by 15%, the power consumption per 100 kilometers has decreased by 8.7%, and the driving range has increased by 45 kilometers. This explores a feasible technical path for the high performance of the drive system.
