...Hilmi Gurleyen Purpose This study aims to analytically model and mitigate unbalanced magnetic forces ( UMF ) in a 6/5 variable flux reluctance machine ( VFRM ) by proposing a dual-stator topology. The objective is to reduce radial-force imbalance and mechanical deformation while maintaining...

... optimization design. Design/methodology/approach First, this paper presents a universal analytical model for slotless Halbach array permanent magnet ( PM ) synchronous motor and derives the air-gap flux density and back electromotive force (back-EMF). Second, the influence of pole pairs, PM thickness...

... work related to five-phase DFIG framing, including the development of an analytical model, FEM analysis as well as the results of laboratory tests of the prototype. The proposed behavioral level analytical model is based on the winding function approach. The developed DFIG model was used at the design...
