空心谐振感应电机去除了铁芯，使其磁场真正具有三维性质。轴向导体和端绕组现在都成为贡献扭矩生产的主动元件。因此，在设计过程中需要考虑整个绕组。传统的三维有限元分析计算量大，难以整合到设计优化中。本文提出了一种考虑空心线圈产生的三维磁场分布的空心谐振感应电机设计优化的新方法，该方法采用Neumann积分的闭型解，计算速度快。本文介绍了文献中两种调谐选项的优化设计：只有定子电容的选项I和既有定子和转子电容的选项II。讨论了不同机械参数下的优化趋势。
The air-cored resonant induction machine removes the iron core which makes its magnetic field truly 3-D in nature. The axial conductors and end windings now both become active components contributing to torque production. The whole winding therefore needs to be considered in the design process. Conventional 3-D finite element analysis has large computational costs and is hard to integrate into the design optimization. This paper presents a new design optimization procedure for air-cored resonant induction machines using closed-form solutions of Neumann integrals which are computationally fast and considers the 3-D magnetic field distributions created by the air-cored coils. Optimized designs for two tuning options in the literature: option I with stator capacitors only and option II with both stator and rotor capacitors, are presented. The optimization trends with respect to different machine parameters are also discussed.
