本文研究了在高性能和高频率的无刷永磁电机设计的电动运动赛车应用，在这种损失有相关的影响接近和集肤效应绕组损耗。详细的有限元分析（FEA），与每个槽的所有导体建模，进行各种绕组配置，单股和多股在手，考虑随机导体放置在定子槽内。提出了一种新的混合分析-有限元分析方法，以加快损失计算，并与纯有限元方法进行了验证。所提出的方法可以进一步用于准确和快速的电机性能估计和优化过程中，避免了全有限元仿真的沉重计算负担。
This paper investigates proximity and skin effects winding losses in a high performance and high frequency brushless permanent magnet machine designed for electric sport racing application, where such losses have a relevant impact. A detailed finite element analysis (FEA), with all conductors per slot modelled, is performed for various winding configurations, with single and multiple strands-in-hand, considering random conductors placement within the stator slots. A new hybrid analytical-FEA method is proposed for speeding up the losses calculation and then validated against pure FEA method. The proposed method can be further used in accurate and fast estimation of the motor performance and in optimization procedures, avoiding heavy computational burden of full FEA simulations.
