Umthelela We-Iron Core Stress Ekusebenzeni KwePermanent Magnet Motors
Ukuthuthuka okusheshayo komnotho kuphinde kwathuthukisa inkambiso yobungcweti yemboni yezimoto zikazibuthe unomphela, kubeka phambili izidingo eziphakeme zokusebenza okuhlobene nemoto, izindinganiso zobuchwepheshe, nokuzinza kokusebenza komkhiqizo.Ukuze amamotho kazibuthe unomphela athuthuke endaweni ebanzi yohlelo lokusebenza, kuyadingeka ukuqinisa ukusebenza okufanele kuzo zonke izici, ukuze izinkomba zekhwalithi nokusebenza kwemoto zifinyelele ezingeni eliphakeme.
Kumamotho kazibuthe unomphela, umgogodla wensimbi uyingxenye ebaluleke kakhulu ngaphakathi kwenjini.Ukukhethwa kwezinto eziyinhloko zensimbi, kuyadingeka ukucabangela ngokugcwele ukuthi i-conductivity kazibuthe ingahlangabezana nezidingo zokusebenza ze-motor magnetic unomphela.Ngokuvamile, insimbi kagesi ikhethwa njengento ewumgogodla wamamotho kazibuthe unomphela, futhi isizathu esiyinhloko ukuthi insimbi kagesi inokuhamba kahle kazibuthe.
Ukukhethwa kwezinto eziyinhloko zemoto kunomthelela obaluleke kakhulu ekusebenzeni okuphelele nokulawulwa kwezindleko zamamotho kazibuthe ahlala njalo.Ngesikhathi sokukhiqiza, ukuhlanganiswa, kanye nokusebenza okusemthethweni kwamamotho kazibuthe ahlala njalo, izingcindezi ezithile zizokwakheka emnyombweni.Kodwa-ke, ukuba khona kokucindezeleka kuzothinta ngokuqondile ukuqhutshwa kazibuthe kweshidi le-Electrical steel, okubangela ukuthi i-conductivity kazibuthe yehle ibe ngamazinga ahlukahlukene, ngakho ukusebenza kwemoto kazibuthe unomphela kuzokwehla, futhi kuzokwandisa ukulahlekelwa kwemoto.
Ekwakheni nasekukhiqizeni amamotho kazibuthe ahlala unomphela, izidingo zokukhethwa kanye nokusetshenziswa kwezinto ziya ngokuya zikhuphuka, zisondele ngisho nezinga elilinganiselwe kanye nezinga lokusebenza kwempahla.Njengento ewumgogodla wamamotho kazibuthe unomphela, insimbi kagesi kumele ihlangabezane nezidingo zokunemba eziphakeme kakhulu kubuchwepheshe bokusebenza obufanele kanye nokubala okunembile kokulahleka kwensimbi ukuze kuhlangatshezwane nezidingo zangempela.
Indlela yendabuko yokuklama imoto esetshenziselwa ukubala izici ze-electromagnetic zensimbi kagesi ngokusobala ayinembile, ngoba lezi zindlela ezivamile zingezezimo ezivamile, futhi imiphumela yokubala izoba nokuchezuka okukhulu.Ngakho-ke, indlela entsha yokubala iyadingeka ukubala ngokunembile ukuqhutshwa kazibuthe kanye nokulahlekelwa kwensimbi yensimbi kagesi ngaphansi kwezimo zensimu yokucindezeleka, ukuze izinga lokusetshenziswa kwezinto eziyinhloko zensimbi liphakeme, futhi izinkomba zokusebenza ezifana nokusebenza kahle kwamamotho kazibuthe unomphela afinyelele. izinga eliphezulu.
U-Zheng Yong nabanye abacwaningi bagxile emthelela wengcindezi eyinhloko ekusebenzeni kwamamotho kazibuthe unomphela, kanye nokuhlaziya okuhlanganisiwe kokuhlola ukuze kuhlolwe izindlela ezifanele zezakhiwo kazibuthe zokucindezeleka nokusebenza kokulahlekelwa kwensimbi yokucindezeleka kwezinto eziyinhloko zikazibuthe.Ukucindezeleka kumgogodla wensimbi wemoto kazibuthe unomphela ngaphansi kwezimo zokusebenza kuthonywa imithombo ehlukahlukene yokucindezeleka, futhi umthombo ngamunye wokucindezeleka ubonisa izakhiwo eziningi ezihluke ngokuphelele.
Ngokombono wefomu lokucindezeleka le-stator core yama-motor kazibuthe unomphela, imithombo yokwakheka kwayo ihlanganisa ukubhoboza, i-riveting, i-lamination, ukuhlanganiswa kokuphazamiseka kwe-casing, njll. indawo yomthelela ebaluleke kakhulu.Kurotha yemoto kazibuthe unomphela, imithombo eyinhloko yengcindezi ethwalayo ihlanganisa ukucindezeleka okushisayo, amandla e-centrifugal, amandla kazibuthe kagesi, njll. Uma kuqhathaniswa namamotho avamile, isivinini esivamile semoto kazibuthe unomphela siphezulu uma kuqhathaniswa, kanye nesakhiwo sokuhlukanisa kazibuthe. iphinde ifakwe ku-rotor core.
Ngakho-ke, ukucindezeleka kwe-centrifugal kuwumthombo oyinhloko wokucindezeleka.Ingcindezi ye-stator core ekhiqizwe ukuhlangana kokuphazamiseka kwesikhwama semoto kazibuthe unomphela sikhona ikakhulukazi ngendlela yengcindezi ecindezelayo, futhi indawo yayo yesenzo igxiliswe ejokeni le-motor stator core, isiqondiso sokucindezeleka sibonakala njenge-circumferential tangential.Isakhiwo sokucindezeleka esakhiwe amandla e-centrifugal we-rotor kazibuthe unomphela ukucindezeleka okuqinile, okucishe kusebenze ngokuphelele kumgogodla wensimbi we-rotor.Ingcindezi enkulu ye-centrifugal isebenza empambanweni yebhuloho elihlukanisayo likazibuthe wemoto kazibuthe kanye nombambo oluqinisayo, okwenza kube lula ukuthi ukonakala kokusebenza kwenzeke kule ndawo.
Umthelela We-Iron Core Stress ku-Magnetic Field of Permanent Magnet Motors
Ukuhlaziya izinguquko ku-magnetic density yezingxenye ezibalulekile zama-motor kazibuthe unomphela, kwatholakala ukuthi ngaphansi kwethonya lokugcwala, kwakungekho shintsho oluphawulekayo ku-magnetic density ezimbanjeni zokuqinisa kanye namabhuloho okuhlukanisa kazibuthe we-motor rotor.Ukuminyana kazibuthe kwe-stator kanye nesekethe kazibuthe eyinhloko yemoto iyahlukahluka kakhulu.Lokhu kungabuye kuchaze umphumela wengcindezi ewumgogodla ekusabalaliseni kokuqina kazibuthe kanye ne-conductivity kazibuthe yemoto ngesikhathi sokusebenza kwemoto kazibuthe unomphela.
Umthelela Wokucindezeleka Ekulahlekeni Okukhulu
Ngenxa yengcindezi, ingcindezi ecindezelayo ejokeni le-stator yemoto kazibuthe unomphela izogxila kakhulu, okuholela ekulahlekelweni okukhulu kanye nokuwohloka kokusebenza.Kunenkinga enkulu yokulahlekelwa kwensimbi ejokeni le-stator yemoto kazibuthe unomphela, ikakhulukazi lapho kuhlangana khona amazinyo e-stator nejoka, lapho ukulahlekelwa kwensimbi kukhula kakhulu ngenxa yokucindezeleka.Ucwaningo luthole ngokubala ukuthi ukulahleka kwensimbi kwamamotho kazibuthe unomphela kuye kwanda ngo-40% -50% ngenxa yethonya lokucindezeleka okuqinile, okusamangalisa impela, ngaleyo ndlela kuholela ekwenyukeni okukhulu kokulahlekelwa okuphelele kwamamotho kazibuthe unomphela.Ngokuhlaziywa, kungatholakala futhi ukuthi ukulahlekelwa kwensimbi ye-motor kuyindlela eyinhloko yokulahlekelwa okubangelwa ithonya lokucindezeleka okucindezelayo ekubunjweni kwe-stator iron core.Ku-motor rotor, lapho i-iron core ingaphansi kokucindezeleka kwe-centrifugal ngesikhathi sokusebenza, ngeke nje yandise ukulahlekelwa kwensimbi, kodwa futhi izoba nomphumela othile wokuthuthukisa.
Umthelela weStress ku-Inductance kanye neTorque
Ukusebenza kwe-magnetic induction ye-motor iron core kuyawohloka ngaphansi kwezimo zengcindezi ye-iron core, futhi i-shaft inductance yayo izokwehla ngezinga elithile.Ikakhulukazi, kuhlaziywa umjikelezo kazibuthe wemoto kazibuthe unomphela, isifunda kazibuthe se-shaft sihlanganisa ikakhulukazi izingxenye ezintathu: igebe lomoya, uzibuthe ongunaphakade, kanye ne-stator rotor iron core.Phakathi kwazo, uzibuthe unomphela ingxenye ebaluleke kakhulu.Ngokusekelwe kulesi sizathu, lapho ukusebenza kwamagnetic induction of unomphela uzibuthe motor iron core izinguquko, ngeke kubangele izinguquko eziphawulekayo inductance shaft.
Ingxenye yesekethe ye-shaft magnetic eyakhiwe igebe lomoya kanye ne-stator rotor core yemoto kazibuthe unomphela incane kakhulu kunokumelana kazibuthe kukazibuthe unomphela.Uma kucatshangelwa umthelela wengcindezi eyinhloko, ukusebenza kukazibuthe kokungeniswa kuyawohloka futhi i-shaft inductance iyancipha kakhulu.Hlaziya umthelela wezimpawu kazibuthe zokucindezeleka kumongo wensimbi wemoto kazibuthe unomphela.Njengoba ukusebenza kukazibuthe kwe-motor core kuncipha, ukuxhumana kazibuthe kwemoto kuncipha, kanye ne-torque kagesi yemoto kazibuthe unomphela nayo iyancipha.
