摘要
本文研究并比较了不同转子拓扑结构的串联磁路可变磁通记忆（VFM）机器的电磁性能。以 V 型变磁通量记忆机为基础，在相同的约束条件下演化并优化了五种具有不同内部永磁体 (IPM) 布置的拓扑结构。基于二维（2-D）有限元（FE）方法，对它们在磁化和退磁状态下的电磁性能进行了评估。结果表明，恒定永磁发电机（CPM）和可变永磁发电机（VPM）之间的铁桥和转子叠片区域对转矩密度和磁通调节（FR）能力起着重要作用。此外，在不同的运行条件下，通过调整磁化状态（MS），可提高变频调速器的整体效率。
Electromagnetic Performance Analysis of Variable Flux Memory Machines with Series-magnetic-circuit and Different Rotor Topologies
In this paper, the electromagnetic performance of variable flux memory (VFM) machines with series-magnetic-circuit is investigated and compared for different rotor topologies. Based on a V-type VFM machine, five topologies with different interior permanent magnet (IPM) arrangements are evolved and optimized under same constrains. Based on two-dimensional (2-D) finite element (FE) method, their electromagnetic performance at magnetization and demagnetization states is evaluated. It reveals that the iron bridge and rotor lamination region between constant PM (CPM) and variable PM (VPM) play an important role in torque density and flux regulation (FR) capabilities. Besides, the global efficiency can be improved in VFM machines by adjusting magnetization state (MS) under different operating conditions.
