It　is　necessary　to　consider　the　torque　and　suspension　force　at　the　same　time　during　the　design　of　bearingless　flux-switching　permanent　magnet　machine　(BFSPMM)　and　how　to　quickly　design　the　key　variables　become　critical.　The　rotor　eccentricity　was　considered　when　building　the　variable　structure　magnetic　network　model　of　BFSPMM,　in　order　to　overcome　the　shortcomings　of　finite　element　time　consuming　and　design　blindness.　The　expressions　of　the　optimal　rotor　to　stator　tooth　width　ratio　and　the　coupling　permanent　magnet　flux　linkage　in　power　winding　are　directly　deduced　based　on　the　network　model　analysis　method.　Then　the　electromagnetic　torque　was　deduced　based　on　the　permanent　magnet　flux　linkage,　and　the　suspension　force　was　further　deduced　by　magnetic　network.　Finally,　the　fast　design　of　key　parameters　was　verified　to　be　effective　by　comparing　with　the　finite　element　analysis　and　the　experimental　results.　©　2017　IEEE.
