The　bearingless　machines　with　permanent　magnet　fixed　on　rotor　have　some　disadvantages,　such　as　permanent　magnet　demagnetization　risk　for　temperature　rising.　So　research　on　bearingless　winding　structure　and　suspension　force　of　flux-switching　machine　with　permanent　magnet　inserted　in　stator　is　conducted　in　this　paper.　Based　on　the　principle　of　reverse　direction　magnetization　for　symmetrical　rotor　teeth,　the　suspension　force　is　developed　by　a　set　of　stator　winding.　The　suspension　force　mathematical　model　is　proposed　after　analyzing　the　form　and　features　of　rotor　Maxwell　force.　The　results　of　finite　element　analysis　show　that　the　rotor　suspension　force　is　almost　determined　by　the　Maxwell　force　from　the　overlap　regions　of　stator　and　rotor　teeth,　and　the　rotor　can　be　suspended　by　the　proposed　suspension　structure　and　force　mathematical　model.　©　2015　IEEE.
