Dual-winding　bearingless　flux-switching　permanent　magnet　machine　(BFSPMM)　is　composed　of　power　winding　and　suspension　winding.　The　permanent　magnet　and　the　power　winding　provide　a　biased　air　gap　magnetic　field,　and　the　suspension　winding　generates　an　air　gap　modulation　magnetic　field.　The　structure　of　stator　and　rotor　are　double　salient　poles.　This　paper　proposes　a　subdomain　model　for　the　on-load　field　prediction　in　dual-winding　BFSPMM.　In　the　developed　model,　the　field　domain　is　divided　into　seven　types　of　subdomains,　viz.　rotor　slot,　internal　air　gap,　stator　slot,　permanent　magnet　slot　upper　layer,　permanent　magnet　slot　lower　layer,　permanent　magnet,　and　external　air　gap.　The　electromagnetic　parameters　of　the　motor　are　analyzed,　including　air　gap　flux　density,　flux　linkage,　back-EMF,　suspension　forces,　and　electromagnetic　torque.　Based　on　the　principle　of　conservation　of　magnetomotive　force,　a　distributed　equivalent　magnetic　circuit　model　is　proposed　to　compensate　for　the　magnetic　saturation.　Finally,　the　analytical　predictions　are　verified　by　finite-element　analysis　and　prototype　experiments.
