本文介绍了一种200kW， 20krpm的电动汽车电机的设计。这项研究的目的是设计一种低成本、不含稀土的磁铁电动机，同时确保大规模生产的可行性，并提供比现有技术更高的性能。在整个机器设计过程中，从规格到优化，都考虑了电磁、热和机械约束。为满足项目要求，研究了转子压铸、喷油冷却和发夹绕组等解决方案。从应力和模态的角度考虑机械极限，采用解析和数值方法对机器全速范围内的电磁和连续性能进行计算。
This paper deals with the design of a 200kW, 20krpm machine for an electric vehicle application. The aim of the research is to design a low cost, rare-earth free magnet electric motor while ensuring mass production feasibility and providing higher performance than currently available technologies. Electromagnetic, thermal and mechanical constraints are considered throughout the machine design process, from the specification to the optimization. Rotor die-casting, oil spray cooling and hairpin winding are among the solutions investigated to fulfill the project requirements. Analytical and numerical methods are adopted for electromagnetic and continuous performance calculations over the machine's full speed range, taking into account the mechanical limits from a stress and modal point of view.
