目前，许多电机拓扑结构已经被提出并进行了广泛的研究，这些拓扑结构可以在不牺牲高效率的前提下，扩大电机的运行速度范围，提高电机的消磁能力。在这些机器拓扑结构中，可变磁通永磁电机（VFPMs）是电动汽车/混合动力汽车（EV/HEV）推进的有力候选者。本文试图定量比较两种具有定子-永磁结构的新型mm，它们分别来自SF和可变磁阻（VR）拓扑。将讨论机器的拓扑结构、工作原理和设计考虑。然后对它们的主要电磁性能进行了分析和比较，证实了SF拓扑的优越性。制作了SFMM样机，并进行了实验验证。
Nowadays, numerous electrical machine topologies have been proposed and extensively investigated, which can extend the operating speed range together with the improvement of flux weakening capability without scarifying high efficiency. Amongst these machine topologies, variable-flux permanent magnet machines (VFPMs) are a competent candidate for electric vehicle/hybrid electric vehicle (EV/HEV) propulsion. This paper attempts to quantitatively compare two novel MMs having stator-PM configurations, which are derived from the SF and variable reluctance (VR) topologies, respectively. The machine topology, operating principle and design consideration will be addressed. Then their major electromagnetic performance will be analyzed and compared, which confirms the superiority of SF topology. A SFMM prototype is manufactured, and the experimental validation will be given in the full paper.
