Inta badan giraanta birlabeedka ayaa u baahan in la rinjiyeeyo si loo fududeeyo kala soocidda.Guud ahaan, xudunta budada birta waxaa lagu kala saaraa laba midab.Kuwa sida caadiga ah loo isticmaalo waa casaan/daah-furnaan, jaalle/guduud, cagaar/guduud, cagaar/buluug iyo jaalle/caddaan.Giraanta xudunta u ah manganese guud ahaan waa lagu rinjiyeeyay cagaar, birta-silikon-aluminiumku guud ahaan waa dhammaan madow iyo wixii la mid ah.Dhab ahaantii, midabka giraanta magnetic ka dib marka la toogto waxba kuma laha rinjiga rinjiga lagu buufiyo mar dambe, kaliya waa heshiis warshadaha.Tusaale ahaan, cagaarka wuxuu ka dhigan yahay giraanta birlabeedka ee sarreeya;laba-midab waxay ka dhigan tahay budada birta xudunta u ah giraanta birta;madow wuxuu u taagan yahay giraanta birta-silikon-aluminium ee birta, iwm.
(1) giraanta birlabeedka sare
Inductors giraanta magnetic, waa inaan dhahnaa nikkel-zinc ferrite giraanta magnetka.Giraan magnetic waxa loo qaybiyaa nikkel-zinc iyo manganese-zinc iyadoo loo eegayo maaddada.Dareemidda birlabeedka ee nikkel-zinc ferrite maaddooyinka giraanta magnetka ayaa hadda la isticmaalaa inta u dhaxaysa 15-2000.Maaddada sida caadiga ah loo isticmaalo waa nikkel-zinc ferrite oo leh magnetic permeability of 100- Inta u dhaxaysa 1000, marka loo eego kala-soocidda permeability magnetic, waxa loo qaybiyaa alaabta permeability hoose.Dareemida magnetic-ka ee manganese-zinc ferrite magnetic giraanta maaddooyinka guud ahaan waa ka sarreeyaa 1000, sidaas darteed giraanta magnetka ee ay soo saarto maaddada manganese-zinc waxaa loo yaqaannaa giraanta magnetka ee sarreeya.
Nickel-zinc ferrite giraanta magnetic waxaa guud ahaan loo isticmaalaa fiilooyinka kala duwan, looxyada wareegga, iyo ka hortagga faragelinta qalabka kombiyuutarka.Manganese-zinc ferrite giraanta magnetka waxaa loo isticmaali karaa in lagu sameeyo inductors, transformers, cores filter, head magnetic iyo ulo anteenada.Guud ahaan, hoos u dhigida maaddada maaddada, ayaa sii ballaaranaysa tirada soo noqnoqda ee lagu dabaqi karo;Mar kasta oo ay sare u kacdo maaddada walxaha, ayaa sii yaraanaya tirada inta jeer ee lagu dabaqi karo.
(2) Giraanta ubucda budada birta

Xudunta budada birta waa erey caan ah oo loogu talagalay walxaha magnetic ferric oxide, kaas oo inta badan loo isticmaalo wareegyada korantada si loo xalliyo dhibaatooyinka ku habboonaanta korantada (EMC).Codsiga wax ku oolka ah, walxo kale oo kala duwan ayaa lagu dari doonaa iyadoo loo eegayo shuruudaha shaandhaynta ee kala duwan ee qaybaha kala duwan ee soo noqnoqda.
Koofiyadaha budada magnetic-ka ee hore waxay ahaayeen bir jilicsan oo jilicsan oo ka samaysan budada magnetic birta-silicon-aluminium aluminium.Qalabkan budada birta ah ee birta-silikon-aluminiumka ah waxaa badanaa loo yaqaan "core budada birta".Nidaamkeeda diyaarinta caadiga ah waa: isticmaal Fe-Si-Al alloy magnetic budada in lagu simo kubad-shiidka oo lagu dahaadho lakabka dahaarka iyadoo la adeegsanayo hababka kiimikada, ka dibna ku dar qiyaastii 15wt% binder, isku walaaq si siman, ka dibna caaryada oo adkee, ka dibna kulaylka daaweynta. ( stress reste) si loo sameeyo alaab.Badeecadan dhaqameed ee "Ududmaha Budada Birta" waxay inta badan ka shaqeysaa 20kHz∼200kHz.Sababtoo ah waxay leeyihiin cufnaanta qulqulka magnetka ee saturation aad uga sarreeya marka loo eego ferrites ka shaqeeya isla bandka soo noqnoqda, sifooyinka sare ee DC ee wanaagsan, u dhow eber magnetostriction coefficient, buuq la'aan inta lagu jiro hawlgalka, xasilloonida soo noqnoqda wanaagsan, iyo saamiga waxqabadka-qiimaha sare.Waxaa si weyn loogu isticmaalaa qaybaha elektiroonigga ah sida koronto-bixiyeyaal elektaroonig ah oo sarreeya.Khasaaradooda ayaa ah in buuxinta aan magnet-ka ahayn kaliya aysan soo saarin milanka magnetic, laakiin sidoo kale waxay ka dhigaysaa dariiqa qulqulka magnetic-ka ee joogsada, iyo demagnetization maxalliga ah waxay keenaysaa hoos u dhac ku yimaada awoodda magnetic.
Qalabka budada birta ee dhawaan la sameeyay ee waxqabadka sare leh ayaa ka duwan kan caadiga ah ee budada magnetic birta-silicon-aluminium.Walxaha ceeriin ee la isticmaalo maaha budada magnetic alloy ee waa budada birta saafiga ah ee lagu dahaadhay lakabka dahaarka.Qadarka xiraha aad ayuu u yar yahay, markaa cufnaanta magnetic waa weyn tahay.korodhka baaxadda.Waxay ku shaqeeyaan inta jeer ee dhexdhexaadka hooseeya ee ka hooseeya 5kHz, guud ahaan dhowr boqol oo Hz, taas oo aad uga hooseeya inta jeer ee shaqada ee FeSiAl maaddooyinka budada magnetic.Suuqa bartilmaameedka ahi waa in lagu beddelo xaashiyaha birta silikoon ee matoorada khasaaraha hooseeya, hufnaanta sare iyo fududaynta naqshadaynta 3D.

(3) FeSiAl giraanta magnetic
Giraanta magnetic FeSiAl waa mid ka mid ah giraangiraha magnetic ee leh heerka isticmaalka sare.Erayada fudud, FeSiAl waxay ka kooban tahay aluminium-silicon-iron waxayna leedahay Bmax aad u sarreeya (Bmax waa celceliska Z ugu badnaan ee aagga isku-tallaabta ee xudunta magnetic. cufnaanta qulqulka magnetic.), Luminta xudunta magnetic waa aad uga hooseeya xudunta budada birta ah iyo qulqulka magnetic sare, waxay leedahay magnetostriction hooseeya (sanqadh hoose), waa qalab tamareed oo qiimo jaban, oo aan lahayn gabowga kuleylka, waxaa loo isticmaali karaa in lagu beddelo budada birta Xuddunta waa mid aad u deggan heerkulka sare.
Astaamaha ugu muhiimsan ee FeSiAlZ waa khasaaro ka hooseeya kuwa budada birta ah iyo sifooyinka wanaagsan ee DC ee hadda jira.Qiimuhu maaha kan ugu sarreeya, laakiin maaha kan ugu hooseeya, marka la barbar dhigo xudunta budada birta iyo birta nikkel molybdenum.
Qalabka birta-silicon-aluminium ee budada magnetic wuxuu leeyahay sifooyin birlab iyo birlab ah oo aad u wanaagsan, awood yar oo lumin iyo cufnaanta qulqulka magnetic sare.Marka loo isticmaalo heerkulka heerkulka -55C ~ + 125C, waxay leedahay isku halaynta sare sida caabbinta heerkulka, caabbinta qoyaanka iyo caabbinta gariirka;
Isla mar ahaantaana, kala duwanaansho balaadhan oo ah 60 ~ 160 ayaa la heli karaa.Waa doorashada ugu fiican ee lagu beddeli karo gariiradda wax soo saarka sahayda korantada, PFC inductor iyo inductor resonant, oo leh waxqabad qiimo sare leh.
