本文研究和比较了两种新型混合磁路可变磁通记忆电机（HMC-VFSTs）的电磁性能，它们具有不同的混合永磁体（PM）配置。所研究的HMC-VFPH的几何特征都是由串联和并联磁路拓扑结构的组合，但具有不同的位置的串联和并联PM分支。所开发的HMC设计可结合联合收割机的优点，宽的磁通调节范围的并联结构和优良的意外退磁耐受能力的串联结构。分别描述了所研究的具有不同混合磁体配置的HMC-VFPH的拓扑结构、特征和工作原理。磁路模型被用来分析揭示两台机器的性能指标。采用有限元法对径向磁化（RM）和周向磁化的LCF型HMC-VFS的电磁特性进行了评估和比较。此外，建议的RM型HMC-VFMM与基准内部PM机的性能进行比较。为了验证有限元分析的正确性，对具有RM结构的RM型HMC-VFMM样机进行了实验。
This article investigates and compares the electromagnetic performance of two novel hybrid-magnetic-circuit variable flux memory machines (HMC-VFMMs) with different hybrid permanent magnet (PM) configurations. The investigated HMC-VFMMs are both geometrically characterized by a combination of series and parallel magnetic circuit topologies, but with different positions of series and parallel PM branches. The developed HMC design can combine the merits of wide flux adjustment range in parallel structure and excellent unintentional demagnetization withstand capability in series structure. The topologies, features, and working principles of the studied HMC-VFMMs with different hybrid magnet configurations are described, respectively. The magnetic circuit model is utilized to analytically reveal the performance metrics of the two machines. The electromagnetic characteristics of the radially magnetized (RM) and circumferentially magnetized LCF types of HMC-VFMMs are evaluated and compared by the finite-element method. Furthermore, the performance comparison of the proposed RM-type HMC-VFMM with a benchmark interior PM machine is conducted. The experiments on RM-type HMC-VFMM prototype with RM-structure are carried out to validate the FE analyses.
