Uninzi lwamakhonkco amagnetic kufuneka lupeyintwe ukuququzelela ukwahlula. Ngokuqhelekileyo, i-iron powder core yahlulwa ngemibala emibini. Ezona zisetyenziswa ngokuqhelekileyo zibomvu/zicace, tyheli/bomvu, luhlaza/bomvu, luhlaza/blue and yellow/white. Umsesane ongundoqo wemanganese ngokubanzi Upeyintwe oluhlaza, intsimbi-silicon-aluminiyam ngokubanzi imnyama kwaye njalo njalo. Enyanisweni, umbala wendandatho yamagnetic emva kokudubula akunanto yakwenza nokudaywa kwepeyinti etshizwe kamva, sisivumelwano nje kwishishini. Umzekelo, oluhlaza imele permeability high ring magnetic; Imibala emibini imele intsimbi engumgubo wentsimbi; umnyama umele intsimbi-silicon-aluminiyam magnetic ring, njl.
(1) Umsesane wokungena kwimagnethi ephezulu
I-Magnetic ring inductors, kufuneka sitsho i-nickel-zinc ferrite magnetic ring. I-ring magnetic ihlulwe ibe yi-nickel-zinc kunye ne-manganese-zinc ngokwezinto eziphathekayo. I-magnetic permeability yezinto ze-nickel-zinc ferrite magnetic ring isetyenziswa ngoku ukusuka kwi-15-2000. Izinto ezisetyenziswa ngokuqhelekileyo ziyi-nickel-zinc ferrite ene-magnetic permeability ye-100- Phakathi kwe-1000, ngokwe-classification magnetic permeability, ihlulwe kwizinto eziphantsi zemagnetic permeability. Ukufikeleleka kozibuthe we-manganese-zinc ferrite magnetic ring material idla ngokuba ngaphezulu kwe-1000, ngoko ke i-ring magnetic eveliswa yi-manganese-zinc material ibizwa ngokuba yi-high permeability ring magnetic.
Amakhonkco emagnetic e-nickel-zinc ferrite asetyenziswa ngokubanzi kwiingcingo ezahlukeneyo, iibhodi zeesekethe, kunye nokuchasana nokuphazamiseka kwizixhobo zekhompyuter. I-Manganese-zinc ferrite magnetic rings ingasetyenziselwa ukwenza i-inductors, i-transformers, i-cores filter, iintloko zemagneti kunye neentonga ze-eriyali. Ngokubanzi, okukhona kusezantsi ukungeneka kwezinto, kokukhona ububanzi boluhlu olusebenzayo; okukhona kuphezulu ukungeneka kwezinto, kokukhona kucutha uluhlu olusebenzayo lwamaza.
(2) Intsimbi yomgubo wentsimbi

I-Iron powder core ligama elidumileyo le-magnetic material ferric oxide, esetyenziswa kakhulu kwiisekethe zombane ukusombulula iingxaki zokuhambelana kombane (EMC). Kwisicelo esisebenzayo, ezinye izinto ezahlukeneyo ziya kongezwa ngokweemfuno ezahlukeneyo zokucoca kwiibhendi zamaza ohlukeneyo.
I-powder yangaphambili yamagnetic cores "yayibotshiwe" intsimbi ethambileyo yemagnethi eyenziwe nge-iron-silicon-aluminium alloy powders magnetic. Le ntsimbi ye-silicon-aluminiyam ye-powder core idla ngokubizwa ngokuba yi "iron powder core". Inkqubo yayo eqhelekileyo yokulungiselela yile: sebenzisa i-Fe-Si-Al ingxubevange engumgubo wemagnethi ukuze ithiwe tyaba ngebhola yokusila kwaye igqunywe ngomaleko okhuselayo ngeendlela zemichiza, emva koko wongeze malunga ne-15wt% isibophelelo, udibanise ngokulinganayo, emva koko ubumba kwaye uqiniswe, kwaye emva koko unyango lobushushu. (ukunciphisa uxinzelelo) ukwenza iimveliso. Le mveliso yemveli "yentsimbi yomgubo wentsimbi" isebenza ikakhulu kwi-20kHz∼200kHz. Ngenxa yokuba banogxininiso oluphezulu kakhulu lwemagnethi eguquguqukayo kunee-ferrites ezisebenza kwibhendi yefrikhwensi efanayo, iimpawu ezilungileyo ze-DC superposition, kufutshane ne-zero magnetostriction coefficient, akukho ngxolo ngexesha lokusebenza, uzinzo olulungileyo lwefrikhwensi, kunye nomlinganiselo ophezulu wexabiso lokusebenza. Isetyenziswa ngokubanzi kumacandelo e-elektroniki afana ne-high-frequency electronic transformers. Ukungalungi kwabo kukuba ukuzaliswa okungenamagnetic akuvelisi kuphela ukudityaniswa kwamagnetic, kodwa kwenza indlela yemagnethi ingasebenzi, kwaye i-demagnetization yendawo ikhokelela ekunciphiseni kokungena kazibuthe.
I-powder core yentsimbi esanda kuphuhliswa ihluke kwi-iron-silicon-aluminium magnetic powder core. Imathiriyeli ekrwada esetyenzisiweyo ayisiyiyo ingxubevange engumgubo wemagnethi kodwa ngumgubo wentsimbi ococekileyo oqatywe ngomaleko wokugquma. Ubungakanani be-binder buncinci kakhulu, ngoko ke ubukhulu be-magnetic flux bukhulu. ukwanda kobukhulu. Basebenza kumbindi-ophantsi webhendi engaphantsi kwe-5kHz, ngokubanzi amakhulu ambalwa eHz, ephantsi kakhulu kunokusebenza rhoqo kwe-FeSiAl magnetic powder cores. Imakethi ekujoliswe kuyo kukutshintsha amaphepha entsimbi e-silicon kwiimoto kunye nelahleko ephantsi, ukusebenza kakuhle kunye nokulula koyilo lwe-3D.
I-Magnetic Ring Inductor
(3) Umsesane wemagnethi we-FeSiAl
I-ring magnetic ye-FeSiAl yenye yezangqa ezinozibuthe ezinezinga eliphezulu lokusetyenziswa. Ngamagama alula, i-FeSiAl yenziwe nge-aluminiyam-silicon-iron kwaye ine-Bmax ephezulu kakhulu (i-Bmax yi-avareji ye-Z ephezulu kwindawo enqamlezayo ye-magnetic core. iphantsi kakhulu kune-iron powder core kunye ne-high magnetic flux, ine-magnetostriction ephantsi (ingxolo ephantsi), yinto yokugcina amandla exabiso eliphantsi, akukho ukuguga kwe-thermal, ingasetyenziselwa ukutshintsha i-iron powder Ingundoqo izinzile kakhulu kwiqondo lokushisa eliphezulu.
Iimpawu eziphambili ze-FeSiAlZ zilahleko eziphantsi kune-iron powder cores kunye neempawu ezilungileyo ze-DC zangoku. Ixabiso alilona liphezulu, kodwa alilona liphantsi, xa kuthelekiswa nentsimbi ye-powder core kunye ne-iron nickel molybdenum.
I-iron-silicon-aluminiyam yomgubo wemagnethi ineempawu ezintle zemagneti kunye nemagnethi, ukulahleka kwamandla aphantsi kunye noxinzelelo oluphezulu lwemagnethi. Xa isetyenziswe kwiqondo lokushisa -55C ~ + 125C, inokuthembeka okuphezulu njengokumelana nobushushu, ukuxhathisa ukufuma kunye nokuxhatshazwa kwe-vibration;
Ngexesha elifanayo, uluhlu olubanzi lwe-permeability ye-60 ~ 160 lukhoyo. Lolona khetho lulungileyo lokutshintsha unikezelo lwamandla oluphuma kwikhoyili, i-PFC inductor kunye ne-resonant inductor, kunye nokusebenza kweendleko eziphezulu.
