Umphumela Wokucindezeleka Kwe-Iron Core Emsebenzini We-Ama-Magnet Motors Ahlala Njalo
Intuthuko esheshayo yomnotho iqhubekisele phambili ukuthambekela kobungcweti embonini yezimoto ezisebenza ngogesi ezihlala njalo, ibeka phambili izidingo eziphakeme zokusebenza okuhlobene nezimoto, amazinga obuchwepheshe, kanye nokuzinza kokusebenza komkhiqizo. Ukuze ama-motor ezisebenza ngogesi ezihlala njalo athuthuke ensimini yokusetshenziswa ebanzi, kubalulekile ukuqinisa ukusebenza okufanele kuzo zonke izici, ukuze izinkomba zekhwalithi kanye nokusebenza kwezimoto zifinyelele ezingeni eliphakeme.
Kuma-motor amagnethi ahlala njalo, i-iron core iyisici esibaluleke kakhulu ngaphakathi kwe-motor. Ukuze kukhethwe izinto ze-iron core, kubalulekile ukucabangela ngokugcwele ukuthi i-magnetic conductivity ingahlangabezana yini nezidingo zokusebenza ze-permanent magnet motor. Ngokuvamile, i-Electrical steel ikhethwa njengezinto eziyinhloko zama-permanent magnet motor, futhi isizathu esiyinhloko ukuthi i-Electrical steel ine-magnetic conductivity enhle.
Ukukhethwa kwezinto eziyinhloko zemoto kunomthelela obaluleke kakhulu ekusebenzeni jikelele kanye nokulawulwa kwezindleko zama-magnet motor ahlala njalo. Ngesikhathi sokukhiqiza, ukuhlanganisa, kanye nokusebenza okusemthethweni kwama-magnet motor ahlala njalo, kuzokwakhiwa ukucindezeleka okuthile enkabeni. Kodwa-ke, ukuba khona kokucindezeleka kuzothinta ngqo ukuqhutshwa kwamandla kazibuthe kweshidi lensimbi kagesi, okubangela ukuqhutshwa kwamandla kazibuthe kwehle ngamazinga ahlukahlukene, ngakho ukusebenza kwe-magnet motor ehlala njalo kuzokwehla, futhi kuzokhulisa ukulahleka kwemoto.
Ekuklanyweni nasekukhiqizweni kwama-motor amagnethi ahlala njalo, izidingo zokukhetha nokusetshenziswa kwezinto ziya ngokuya ziphakama, zisondela ngisho nasezingeni elilinganiselwe kanye nezinga lokusebenza kwezinto. Njengezinto eziyinhloko zama-motor amagnethi ahlala njalo, insimbi kagesi kumele ihlangabezane nezidingo zokunemba okuphezulu kakhulu kubuchwepheshe bokusetshenziswa obufanele kanye nokubalwa okunembile kokulahlekelwa yinsimbi ukuze kuhlangatshezwane nezidingo zangempela.
Indlela yendabuko yokuklama imoto esetshenziswa ukubala izici ze-electromagnetic zensimbi kagesi ngokusobala ayilungile, ngoba lezi zindlela ezivamile zisebenza kakhulu ezimweni ezivamile, futhi imiphumela yokubala izoba nokuphambuka okukhulu. Ngakho-ke, kudingeka indlela entsha yokubala ukuze kubalwe ngokunembile ukuhanjiswa kwamandla kazibuthe kanye nokulahlekelwa yinsimbi kwensimbi kagesi ngaphansi kwezimo zensimu yokucindezeleka, ukuze izinga lokusetshenziswa kwezinto eziyinhloko yensimbi libe phezulu, futhi izinkomba zokusebenza ezifana nokusebenza kahle kwama-magnet motor ahlala njalo zifinyelele ezingeni eliphakeme.
UZheng Yong nabanye abacwaningi bagxile emthonjeni wokucindezeleka okuyinhloko ekusebenzeni kwama-motor amagnethi ahlala njalo, kanye nokuhlaziywa kokuhlola okuhlanganisiwe ukuhlola izindlela ezifanele zezakhiwo zikagesi ezicindezelayo kanye nokusebenza kokulahlekelwa yinsimbi yokucindezeleka kwezinto eziyinhloko ze-motor magnethi ehlala njalo. Ukucindezeleka okusenhliziyweni yensimbi ye-motor magnethi ehlala njalo ngaphansi kwezimo zokusebenza kuthonywa yimithombo ehlukahlukene yokucindezeleka, futhi umthombo ngamunye wokucindezeleka ubonisa izakhiwo eziningi ezihlukene ngokuphelele.
Ngokombono wohlobo lokucindezeleka kwe-stator core yama-magnet motor ahlala njalo, imithombo yokwakheka kwawo ifaka phakathi ukubhoboza, ukugoba, ukujikijela, ukuhlanganiswa kokuphazamiseka kwe-casing, njll. Umphumela wokucindezeleka obangelwa ukuhlanganiswa kokuphazamiseka kwe-casing unendawo enkulu kakhulu nebaluleke kakhulu yomthelela. Kwi-rotor ye-magnet motor ehlala njalo, imithombo eyinhloko yokucindezeleka ethwalayo ifaka phakathi ukucindezeleka kokushisa, amandla e-centrifugal, amandla kagesi, njll. Uma kuqhathaniswa nama-motor avamile, ijubane elijwayelekile le-magnet motor ehlala njalo liphezulu kakhulu, futhi isakhiwo sokuhlukaniswa kwamandla kagesi sifakiwe naso ku-rotor core.
Ngakho-ke, ukucindezeleka kwe-centrifugal kuwumthombo oyinhloko wokucindezeleka. Ukucindezeleka kwe-stator core okubangelwa ukuhlanganiswa kokuphazamiseka kwe-permanent magnet motor casing kutholakala kakhulu ngesimo sokucindezeleka okucindezelayo, futhi iphuzu layo lokusebenza ligxile ejokeni le-motor stator core, kanye nesiqondiso sokucindezeleka esibonakala njenge-circumferential tangential. Isici sokucindezeleka esakhiwe amandla e-centrifugal e-permanent magnet motor rotor ukucindezeleka kokudonsa, okusebenza cishe ngokuphelele enkabeni yensimbi ye-rotor. Ukucindezeleka okuphezulu kwe-centrifugal kusebenza ekuxhumaneni kwe-permanent magnet motor rotor magnetic isolation bridge kanye ne-reinforcering rib, okwenza kube lula ukuthi ukusebenza kuphazamiseke kule ndawo.
Umphumela Wokucindezeleka Kwe-Iron Core Ensimini Yama-Magnetic Yama-Permanent Magnet Motors
Ukuhlaziya izinguquko ekuxineni kwamagnetic kwezingxenye ezibalulekile zama-magnet motor ahlala njalo, kwatholakala ukuthi ngaphansi kwethonya lokugcwala, bekungekho ushintsho oluphawulekayo ekuxineni kwamagnetic ezinhlangothini zokuqinisa kanye namabhuloho okuhlukaniswa kwamagnetic e-motor rotor. Ubuningi bamagnetic be-stator kanye nesekethe eliyinhloko lamagnetic lemoto buyahlukahluka kakhulu. Lokhu kungachaza futhi umphumela wokucindezeleka okuyinhloko ekusabalalisweni kobuningi bamagnetic kanye nokuqhuba kwamagnetic kwemoto ngesikhathi sokusebenza kwe-magnet motor ehlala njalo.
Umphumela Wokucindezeleka Ekulahlekelweni Okuyinhloko
Ngenxa yokucindezeleka, ukucindezeleka okucindezelayo ejokeni le-stator ye-magnet motor ehlala njalo kuzoba kugxile kakhulu, okuholela ekulahlekelweni okukhulu kanye nokuwohloka kokusebenza. Kunenkinga enkulu yokulahlekelwa yinsimbi ejokeni le-stator ye-magnet motor ehlala njalo, ikakhulukazi lapho kuhlangana khona amazinyo e-stator ne-joke, lapho ukulahlekelwa yinsimbi kukhula kakhulu ngenxa yokucindezeleka. Ucwaningo luthole ngokubala ukuthi ukulahlekelwa yinsimbi kwama-magnet motor ehlala njalo kukhuphuke ngo-40% -50% ngenxa yethonya lokucindezeleka kokudonsa, okusamangalisa kakhulu, ngaleyo ndlela kuholele ekwandeni okukhulu kokulahlekelwa okuphelele kwama-magnet motor ehlala njalo. Ngokuhlaziya, kungatholakala futhi ukuthi ukulahlekelwa yinsimbi kwemoto kuyindlela eyinhloko yokulahlekelwa okubangelwa ithonya lokucindezeleka kokucindezela ekwakhekeni kwe-stator iron core. Kwi-rotor yemoto, lapho i-iron core ingaphansi kokucindezeleka kokudonsa kwe-centrifugal ngesikhathi sokusebenza, ngeke nje kuphela ikhulise ukulahlekelwa yinsimbi, kodwa futhi izoba nomphumela othile wokuthuthukisa.
Umphumela Wokucindezeleka Ekungeneni Kwe-Inductance kanye ne-Torque
Ukusebenza kokungeniswa kwamagnetic kwe-motor iron core kuyawohloka ngaphansi kwezimo zokucindezeleka kwe-iron core, futhi ukugeleza kwayo komgodi kuzokwehla ngezinga elithile. Ngokukhethekile, lapho kuhlaziywa isekethe yamagnetic ye-permanent magnet motor, isekethe yamagnetic ye-shaft ihlanganisa ikakhulukazi izingxenye ezintathu: igebe lomoya, i-permanent magnet, kanye ne-stator rotor iron core. Phakathi kwazo, i-permanent magnet iyingxenye ebaluleke kakhulu. Ngokusekelwe kulesi sizathu, lapho ukusebenza kokungeniswa kwamagnetic kwe-permanent magnet motor iron core kushintsha, akunakubangela izinguquko ezinkulu ekungeneni komgodi.
Ingxenye yesekethe yamagnetic yeshaft eyakhiwe yigebe lomoya kanye ne-stator rotor core yemoto yamagnet ehlala njalo incane kakhulu kunokumelana kwamagnetic kwemagnet ehlala njalo. Uma kucatshangelwa ithonya lokucindezeleka okuyinhloko, ukusebenza kwe-magnetic induction kuyawohloka futhi i-shaft inductance iyancipha kakhulu. Hlaziya umthelela wezakhiwo zamagnetic zokucindezeleka enkabeni yensimbi yemoto yamagnet ehlala njalo. Njengoba ukusebenza kwe-magnetic induction ye-motor core kuncipha, ukuxhumana kwamagnetic kwemoto kuyancipha, kanye ne-torque ye-electromagnetic yemoto yamagnet ehlala njalo nayo iyancipha.
