Parasitic Currents in Stray Paths of Some Topologies of YASA AFPM Machines: Trend With Machine Size [PDF]
IEEE Transactions on Industrial Electronics, 2016 In some topologies of yokeless and segmented armature (YASA) axial flux permanent-magnet (AFPM) machines, the particular frame structure required to fasten floating teeth can originate stray paths where parasitic currents may circulate. This paper investigates how the amplitude of these currents and the related additional Joule losses depend on the ...
