Isiphumo soxinzelelo lwe-Iron Core ekusebenzeni kweIiMotor zeMagnet ezisisigxina
Uphuhliso olukhawulezayo loqoqosho lukhuthaze ngakumbi indlela yokusebenza ngobuchwephesha kwishishini leemoto ezizibuthe ezisisigxina, libeka phambili iimfuno eziphezulu zokusebenza okunxulumene nemoto, imigangatho yobugcisa, kunye nozinzo lokusebenza kwemveliso.Ukuze iimotor zemagnethi ezisisigxina zikhule kwindawo ebanzi yesicelo, kuyafuneka ukomeleza ukusebenza okufanelekileyo kuzo zonke iinkalo, ukuze umgangatho uwonke kunye nezalathisi zokusebenza zemoto zifikelele kwinqanaba eliphezulu.
Kwiimotor zemagnethi ezisisigxina, undoqo wentsimbi licandelo elibaluleke kakhulu ngaphakathi kwenjini.Ukukhethwa kwezinto eziphambili zentsimbi, kuyimfuneko ukuqwalasela ngokupheleleyo ukuba i-conductivity magnetic ingahlangabezana neemfuno zokusebenza ze-motor magnetic esisigxina.Ngokubanzi, intsimbi yoMbane ikhethwa njengeyona nto iphambili yeenjini zemagnethi ezisisigxina, kwaye esona sizathu sesokuba intsimbi yoMbane inokusebenza kakuhle kwemagnethi.
Ukukhethwa kwezinto eziphambili zeemoto kunempembelelo ebaluleke kakhulu ekusebenzeni ngokubanzi kunye nokulawulwa kweendleko zeenjini ezisisigxina zemagnethi.Ngexesha lokwenziwa, ukudityaniswa, kunye nokusebenza ngokusesikweni kweenjini zemagnethi ezisisigxina, uxinzelelo oluthile luya kwenza kumbindi.Nangona kunjalo, ubukho boxinzelelo buya kuchaphazela ngokuthe ngqo ukuhanjiswa kwamagnetic kweshiti lentsimbi yoMbane, okubangela ukuba ukuhanjiswa kwamagnetic kwehle ukuya kumaqondo ahlukeneyo, ke ukusebenza kwemagnethi esisigxina kuya kuncipha, kwaye kuya kwandisa ilahleko yemoto.
Kuyilo kunye nokwenziwa kweenjini zemagnethi ezisisigxina, iimfuno zokhetho kunye nokusetyenziswa kwemathiriyeli ziya ziphakama kwaye ziphezulu, zisondele kumda womgangatho kunye nenqanaba lokusebenza kwemathiriyeli.Njengeyona nto ingundoqo yeenjini zemagnethi ezisisigxina, intsimbi yoMbane kufuneka ihlangabezane neemfuno ezichanekileyo zokuchaneka okuphezulu kakhulu kubuchwephesha besicelo esifanelekileyo kunye nokubalwa okuchanekileyo kwelahleko yentsimbi ukuze kuhlangatyezwane neemfuno zokwenyani.
Indlela yoyilo lwemoto yemveli esetyenziselwa ukubala iimpawu ze-electromagnetic zentsimbi yoMbane ngokucacileyo ayichanekanga, kuba ezi ndlela ziqhelekileyo zenzelwe iimeko eziqhelekileyo, kwaye iziphumo zokubala ziya kuba nokutenxa okukhulu.Ke ngoko, indlela entsha yokubala iyadingeka ukubala ngokuchanekileyo ukuqhutywa kwamagnetic kunye nokulahleka kwentsimbi yentsimbi yoMbane phantsi kweemeko zentsimi yoxinzelelo, ukuze inqanaba lesicelo sezinto ezingundoqo zentsimbi liphezulu, kunye nezalathisi zokusebenza ezifana nokusebenza kakuhle kweenjini zemagnethi ezisisigxina zifikelele. inqanaba eliphezulu.
UZheng Yong kunye nabanye abaphandi bagxile kwimpembelelo yoxinzelelo olungundoqo ekusebenzeni kweenjini zemagnethi ezisisigxina, kunye nohlalutyo oludityanisiweyo lokuphonononga iindlela ezifanelekileyo zoxinzelelo lweepropathi zemagneti kunye noxinzelelo lwentsimbi yokusebenza kwentsimbi yezinto eziphambili zemagnethi.Uxinzelelo kumbindi wentsimbi yenjini yemagnethi esisigxina phantsi kweemeko zokusebenza iphenjelelwa yimithombo eyahlukeneyo yoxinzelelo, kwaye umthombo ngamnye woxinzelelo ubonisa iipropathi ezininzi ezahlukeneyo ngokupheleleyo.
Ngokombono wendlela yoxinzelelo lwesiseko se-stator yeenjini zemagnethi ezisisigxina, imithombo yokwakheka kwayo ibandakanya ukubethelwa, ukubethelwa, i-lamination, indibano yokuphazamiseka kwe-casing, njl. njl. eyona ndawo yempembelelo ibalulekileyo.Kwi-rotor ye-motor yemagnethi esisigxina, eyona mithombo yoxinzelelo oluyithweleyo ibandakanya uxinzelelo lwe-thermal, amandla e-centrifugal, amandla ombane we-electromagnetic, njl. njl. ifakwe kwakhona kwi-rotor core.
Ke ngoko, uxinzelelo lwe-centrifugal ngowona mthombo woxinzelelo.Uxinzelelo olungundoqo lwe-stator oluveliswa yindibano yokuphazamiseka ye-magnetic motor casing esisigxina ubukhulu becala ikhona ngendlela yoxinzelelo loxinzelelo, kwaye indawo yayo yesenzo igxile kwidyokhwe ye-motor stator core, kunye nomkhombandlela woxinzelelo obonakaliswa njenge-circumferential tangential.Ipropathi yoxinzelelo eyenziwe ngamandla e-centrifugal yerotor yemagnethi esisigxina luxinzelelo loxinzelelo, oluphantse lusebenze ngokupheleleyo kumbindi wentsimbi werotor.Olona xinzelelo luphezulu lwe-centrifugal lusebenza ekudibaneni kwebhulorho yemagnethi esisigxina ye-rotor yemagnethi kunye nokuqinisa iimbambo, okwenza kube lula ukuthotywa komgangatho wentsebenzo kule ndawo.
Isiphumo soxinzelelo lwe-Iron Core kwiNdawo yeMagnetic yeeMoto eziziGxina zeMagnet
Ukuhlalutya utshintsho kwi-magnetic density yeendawo eziphambili zee-magnetic motors ezisisigxina, kwafunyaniswa ukuba phantsi kweempembelelo zokugcwala, akukho tshintsho lubalulekileyo kwi-magnetic density kwiimbambo zokuqinisa kunye neebhulorho zokuhlukaniswa kwamagnetic ze-motor rotor.Ubuninzi bemagnethi ye-stator kunye nesekethe enkulu yemagnethi yemoto iyahluka kakhulu.Oku kunokuphinda kuchaze isiphumo soxinzelelo olungundoqo ekuhanjisweni koxinaniso lwemagnethi kunye ne-conductivity yemagnethi yemoto ngexesha lokusebenza kwenjini yemagnethi esisigxina.
Isiphumo soxinzelelo kwi-Core Loss
Ngenxa yoxinzelelo, uxinzelelo olucinezelayo kwidyokhwe yemagnethi esisigxina ye-motor stator iya kugxila kakhulu, okukhokelela kwilahleko enkulu kunye nokwehla kokusebenza.Kukho ingxaki enkulu yokulahleka kwentsimbi kwidyokhwe yemagnethi esisigxina ye-motor stator, ngakumbi ekudibaneni kwamazinyo e-stator kunye nedyokhwe, apho ilahleko yentsimbi inyuka kakhulu ngenxa yoxinzelelo.Uphando lufumene ngokubala ukuba ilahleko yentsimbi yeenjini zemagnethi esisigxina yonyuke nge-40% -50% ngenxa yempembelelo yoxinzelelo lwe-tensile, nto leyo isemangalisa kakhulu, nto leyo ekhokelela ekonyukeni okukhulu kwilahleko iyonke yeenjini zemagnethi ezisisigxina.Ngokuhlalutya, kunokufunyanwa kwakhona ukuba ilahleko yentsimbi yemoto yindlela ephambili yokulahleka okubangelwa yimpembelelo yoxinzelelo loxinzelelo ekubunjweni kwesiseko sentsimbi ye-stator.Kwi-rotor ye-motor, xa i-iron core iphantsi koxinzelelo lwe-centrifugal ngexesha lokusebenza, ayiyi kwandisa ilahleko yentsimbi kuphela, kodwa iya kuba nefuthe elithile lokuphucula.
Isiphumo soxinzelelo kwi-Inductance kunye neTorque
Ukusebenza kokufakelwa kwamagnetic kumbindi wentsimbi yemoto kuwohloka phantsi kweemeko zoxinzelelo lwentsimbi engundoqo, kwaye inductance yayo ye-shaft iya kuncipha ukuya kuthi ga kwinqanaba elithile.Ngokukodwa, ukuhlalutya isekethe yemagnethi yemoto umazibuthe osisigxina, isekethe yemagnethi yeshaft ibandakanya ikakhulu iinxalenye ezintathu: umsantsa womoya, umazibuthe osisigxina, kunye nondoqo wentsimbi yestator.Phakathi kwabo, imagnethi esisigxina yeyona nxalenye ibalulekileyo.Ngokusekwe kwesi sizathu, xa ukusebenza kwamagnetic induction yemagnethi esisigxina yentsimbi itshintsha, ayinakubangela utshintsho olubalulekileyo kwi-shaft inductance.
Inxalenye yesekethe yemagnethi yeshaft eyenziwe sisikhewu somoya kunye nondoqo westator rotor yemoto enemagnethi esisigxina incinci kakhulu kunokumelana nemagnethi yemagnethi esisigxina.Ukuthathela ingqalelo impembelelo yoxinzelelo olungundoqo, ukusebenza kwemagnethi kuyancipha kwaye inductance ye-shaft iyancipha kakhulu.Hlalutya impembelelo yoxinzelelo lweepropathi zemagneti kumbindi wentsimbi wenjini yemagnethi esisigxina.Njengoko ukusebenza kwemagnethi ye-motor core kuncipha, unxibelelwano lwemagnethi lwemoto luyehla, kunye ne-torque ye-electromagnetic yemoto umazibuthe esisigxina nayo iyehla.
