A　dual-winding　complementary　suspension　fault-tolerant　control　strategy　for　the　six-phase　and　three-phase　dual-winding　bearingless　flux-switching　permanent　magnet　motor　(BFSPMM)　is　proposed　in　this　paper.　If　one　phase　of　the　six-phase　winding　is　missing,　the　remaining　5　healthy　phases　can　still　generate　torque,　but　the　stability　of　the　rotor　suspension　control　is　affected　by　the　disturbance　suspension　force　generated　by　current　in　the　symmetric　phase　of　missing　phase.　Therefore,　a　fault-tolerant　control　strategy　for　BFSPMM　with　two　symmetric　missing　phases　is　studied　in　this　paper.　Let　the　remaining　4　healthy　phases　generate　torque　and　compensation　suspension　force　according　to　the　principle　that　the　copper　loss　of　the　suspension　current　is　minimal.　The　compensation　suspension　force　and　the　main　suspension　force　generated　by　the　three-phase　windings　achieve　the　stable　suspension　of　the　rotor.　The　theoretical　analysis　and　Matlab　simulation　prove　that　the　proposed　control　strategy　is　effective.　©　2018　KIEE　EMECS　(KIEE　Electrical　Machinery　and　Energy　Conversion　Systems).
