“…In order to avoid UD issue and enhance working points of VPM, series-magnetic-circuit VFM machines are proposed in [16]- [23]. In [16] and [17], flat-type and V-type PM configurations are employed, respectively, in which CPM and VPM are alternatively placed in the adjacent pole, which can achieve high torque density as conventional IPM machines whilst gain FR capability.…”

“…In [22], the delta-type PM arrangements are proposed with particular considering the effect of iron bridge between CPM and VPM. The magnetization characteristics of VFM machines with segregated dual-three windings are focused on [23] based on delta-type PM configurations. Moreover, to synthesis the merits of the two type of VFM machines, the series-parallel VFM machines are presented in [3], [25] and [26].…”

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 (1PM) 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.
