Ukuphepha nokuthembeka ekuthuthukisweni nasekusetshenzisweni kwamakheshi emoto kazibuthe unomphela.
Ama-motor synchronous kazibuthe ahlala njalo athuthukisiwe futhi asetshenziswa ekwakhiweni nasekukhiqizeni ikheshi, okuthuthukisa kakhulu ukuphepha nokuthembeka kwezinhlelo zokudonsa kwekheshi. Lapho ibhuleki lomshini wokudonsa lihluleka noma amanye amaphutha edala ukuthi ikheshi lishelele futhi ligijime ngokushesha, linomsebenzi wokuvikela ukuphepha, ohlangabezana nezimfuneko zezinga lobuchwepheshe lezwe lami le-GB7588-2003 (Isicaciso Sokuphepha Sokukhiqiza Nokufakwa Kwekheshi) 9.10 “Idivayisi Yokuvikela Isikhumulo Esiphezulu Esinesivinini Esingaphezulu”. Ku-lifti esebenzisa injini yamagnethi ehambisanayo ehambisanayo, lapho i-TV ima ukusebenza, ukujikajika kwe-armature yenjini kuba yi-circuited short-circuited (noma i-serialized).
Ukuphepha nokuthembeka ekuthuthukisweni nasekusetshenzisweni kwamakheshi emoto kazibuthe unomphela.
I-Permanent magnet synchronous motor iye yathuthukiswa futhi yasetshenziswa ekwakhiweni nasekukhiqizeni ikheshi, okuthuthukisa kakhulu ukuphepha nokuthembeka kohlelo lokudonsa kwekheshi. Lapho ibhuleki lomshini wokudonsa lihluleka noma amanye amaphutha edala ukuthi ikheshi lishelele futhi ligijime ngokushesha, linomsebenzi wokuvikela ukuphepha, ohlangabezana nezimfuneko zezinga lobuchwepheshe lezwe lami le-GB7588-2003 (Isicaciso Sokuphepha Sokukhiqiza Nokufakwa Kwekheshi) 9.10 “Idivayisi Yokuvikela Isikhumulo Esiphezulu Esinesivinini Esingaphezulu”. Ku-lifti esebenzisa injini edonsayo kazibuthe evumelanayo, lapho i-TV ima ukusebenza, ukujikajika kwe-armature yenjini kuba yi-circuited emfushane (noma i-circuited short-circuited ngemva kokuthi isixhasi esilungisekayo sixhunywe ochungechungeni). Uma kwenzeka iphutha le-overspeed (noma ngabe liyakhuphuka noma liyawa, isistimu yokulawula ithola isignali enesivinini esikhulu, inqamule ngokushesha isekethe yokuphakela amandla yesilawuli, bese ifinyeza i-armature winding yemoto (noma isixhasi esilungisekayo ochungechungeni). Ngalesi sikhathi, ukujikajika okumile kunqamula insimu kazibuthe ekhiqizwa uzibuthe ozungezayo, futhi kubangele amandla e-electromotive, akhiqiza i-current kusekethe yokumayoko evaliwe ye-armature, bese ikhiqiza i-torque ngaphansi kwesenzo sikazibuthe, izama ukushayela. i-armature winding ukuze ijikeleze kanye nesigxobo kazibuthe. Ngesikhathi esifanayo, i-torque reaction torque isebenza ezigxotsheni ze-rotor, izama ukumisa i-rotor kanye ne-stator armature winding, okuwuhlobo lwe-torque yokubhuleka. Le nqubo ifana ne-dynamic braking yama-motor e-DC, ukuze kuzuzwe ukuvimbela ukuwa nokubalekela (i-torque yokubhuleka ingashintshwa ngokumelana nokulawula isivinini sokugijima). Ukusebenzisana kukazibuthe unomphela kanye ne-armature winding evaliwe kukhiqiza ukuvikeleka okungathinteki ngezindlela ezimbili zokuzivala endaweni yokupaka, okwandisa kakhulu ukuphepha nokuthembeka kwekheshi, ikakhulukazi kunciphisa umkhawulo wokuphepha wamakheshi ahlukahlukene anesivinini esikhulu. Amabhande alimele ngesivinini esiphezulu ezingozini zokuphepha.
