ABSTRACT　　The　invention　relates　to　a　magnetically　levitated　nutation　artificial　heart　pump,　　comprising　an　　upper　cover,　　a　lower　cover,　　an　annular　housing,　　a　nutation　mechanism　and　a　levitation　detection　　mechanism;　　the　nutation　mechanism　divides　an　accommodation　chamber　into　a　first　chamber　　and　a　second　chamber,　　the　nutation　mechanism　includes　a　nutating　disk　and　a　driving　magnet,　　　and　the　levitation　detection　mechanism　includes　:　　a　magnet　ball　pair,　　including　a　first　　hemispherical　magnet　and　a　second　hemispherical　magnet;　　a　levitation　magnet　assembly,　　　including　a　first　levitation　magnet　and　a　second　levitation　magnet;　　the　levitation　magnet　and　　the　first　hemispherical　magnet　have　the　same　magnetic　properties,　　and　the　second　levitation　　magnet　and　the　second　hemispherical　magnet　have　the　same　magnetic　properties　so　that　the　　magnet　ball　pair　is　suspended　in　the　accommodation　chamber;　　and　an　eddy　current　sensor,　　　which　has　a　preset　distance　from　the　first　hemispherical　magnet　gap;　　the　eddy　current　sensor　　obtains　the　actual　gap　between　it　and　the　magnet　ball　pair　by　obtaining　the　impedance　value　　generated　between　it　and　the　first　hemispherical　magnet　after　power-on,　　so　as　to　obtain　the　　levitation　state　of　the　magnet　ball　pair.　The　invention　also　provides　a　magnetically　levitated　　nutation　artificial　heart　pump　system.　1/3　　FIGURES　　222　　21　　＜22　　51　52　　7　8　　5　　Figure　1
