Byinshi mu mpeta za rukuruzi bigomba gusiga irangi kugirango byorohereze itandukaniro.Mubisanzwe, ifu yifu yicyuma itandukanijwe namabara abiri.Ibikunze gukoreshwa ni umutuku / umucyo, umuhondo / umutuku, icyatsi / umutuku, icyatsi / ubururu n'umuhondo / cyera.Impeta yibanze ya manganese muri rusange Irangi Icyatsi, icyuma-silicon-aluminium muri rusange byose birabura nibindi.Mubyukuri, ibara ryimpeta ya magneti nyuma yo kurasa ntaho rihuriye no gusiga irangi ryatewe nyuma, ni amasezerano gusa muruganda.Kurugero, icyatsi cyerekana impeta ndende ya magnetiki impeta;amabara abiri yerekana ifu y'ifu ya magnetiki impeta;umukara ugereranya icyuma-silikoni-aluminium impeta, nibindi.
(1) Impeta ndende ya magnetiki
Impinduramatwara ya rukuruzi, tugomba kuvuga nikel-zinc ferrite impeta.Impeta ya magneti igabanijwemo nikel-zinc na manganese-zinc ukurikije ibikoresho.Magnetic permeability ya nikel-zinc ferrite ibikoresho bya magnetiki impeta ikoreshwa kugeza ubu kuva 15-2000.Ibikoresho bikoreshwa cyane ni nikel-zinc ferrite ifite magnetiki ya 100- Hagati ya 1000, ukurikije ibyiciro bya magnetiki byinjira, igabanijwemo ibikoresho bike bya magneti.Magnetic permeability ya manganese-zinc ferrite ya magnetiki impeta muri rusange iri hejuru ya 1000, bityo impeta ya magnetiki ikorwa nibikoresho bya manganese-zinc yitwa impeta nini ya magnetiki.
Impeta ya Nickel-zinc ferrite ikoreshwa mubusanzwe insinga zitandukanye, imbaho ​​zumuzunguruko, hamwe no kurwanya kwivanga mubikoresho bya mudasobwa.Impeta ya Manganese-zinc ferrite irashobora gukoreshwa mugukora inductors, transformateur, kayunguruzo, imitwe ya magneti hamwe na antenna.Muri rusange, munsi yibikoresho byoroshye, niko byaguka inshuro zikoreshwa;murwego rwohejuru rwibintu byoroshye, bigufi bikurikizwa.
(2) Impeta y'ifu y'icyuma impeta

Ifu yifu yicyuma nijambo ryamamare kubintu bya magnetiki ferric oxyde, ikoreshwa cyane cyane mumashanyarazi kugirango ikemure ibibazo bya electromagnetic ihuza (EMC).Mubikorwa bifatika, ibindi bintu bitandukanye bizongerwaho ukurikije ibisabwa bitandukanye byo kuyungurura mumirongo itandukanye.
Ifu ya magnetiki yambere yambere yari "ihujwe" ibyuma byoroheje bya magnetiki bikozwe mubyuma-silicon-aluminium alloy magnetique.Iyi fer-silicon-aluminium ya porojeri yifu bakunze kwitwa "ifu yifu yicyuma".Uburyo busanzwe bwo gutegura ni: koresha ifu ya magneti ya Fe-Si-Al alloy kugirango uhindurwe no gusya umupira hanyuma ushyirwemo urwego rukingira hakoreshejwe uburyo bwa shimi, hanyuma wongereho hafi 15wt% binder, uvange neza, hanyuma ubumbabumbe kandi ushikame, hanyuma uvure ubushyuhe (kugabanya impagarara) gukora ibicuruzwa.Ibicuruzwa gakondo "ifu yifu yicyuma" ikora cyane kuri 20kHz∼200kHz.Kuberako bafite ubwinshi bwuzuye bwuzuye bwa magnetiki flux yuzuye kuruta ferrite ikora mumurongo umwe, ibyiza biranga DC superposition, hafi ya zeru ya magnetostriction ya zero, nta rusaku mugihe gikora, guhagarara neza kwumuvuduko, hamwe nigipimo kinini cyibiciro.Irakoreshwa cyane mubice bya elegitoronike nka transfert ya elegitoronike.Ingaruka zabo ni uko kuzuza ibintu bitari magnetique bidatanga gusa imbaraga za rukuruzi, ahubwo binatuma inzira ya magnetiki flux idahagarara, kandi demagnetisation yaho iganisha ku kugabanuka kwa rukuruzi.
Ifu ya porojeri iherutse gukorwa cyane itandukanye nicyuma gakondo-silicon-aluminium ya porojeri.Ibikoresho fatizo bikoreshwa ntabwo ari ifu ya magnetiki ahubwo ni ifu yicyuma isize hamwe.Ingano ya binder ni nto cyane, bityo ubwinshi bwa magnetiki flux ni nini.kwiyongera mubunini.Bakora mumashanyarazi yo hagati-munsi ya 5kHz, mubisanzwe Hz amajana make, ibyo bikaba biri munsi yumurongo wakazi wa FeSiAl ya poweri yifu ya cores.Isoko rigamije ni ugusimbuza ibyuma bya silicon ibyuma bya moteri hamwe nigihombo cyayo gito, gukora neza no koroshya igishushanyo cya 3D.
Indanganturo ya Magnetique
(3) Impeta ya magneti ya FeSi
Impeta ya magnetiki ya FeSiAl nimwe mu mpeta ya magneti ifite igipimo kinini cyo gukoresha.Mumagambo yoroshye, FeSiAl igizwe na aluminium-silicon-fer kandi ifite Bmax ndende cyane (Bmax ni impuzandengo ya Z ntarengwa ku gice cyambukiranya igice cya magnetiki. Magnetic flux density.), Igihombo cya magneti ni munsi cyane kurenza ifu yifu nicyuma kinini cya magnetiki, ifite magnetostriction nkeya (urusaku ruke), nibikoresho byo kubika ingufu zihenze, nta gusaza kwumuriro, birashobora gukoreshwa mugusimbuza ifu yicyuma Intangiriro irahagaze neza mubushyuhe bwinshi.
Ibintu nyamukuru biranga FeSiAlZ nigihombo gito ugereranije nifu yifu yicyuma nibiranga DC kubogama kurubu.Igiciro ntabwo kiri hejuru, ariko ntabwo kiri hasi, ugereranije nifu ya puderi yicyuma na nikel molybdenum.
Ifu ya silicon-aluminium ya porojeri ifu ifite ibintu byiza bya magnetiki na magnetique, gutakaza ingufu nke hamwe nubucucike bukabije bwa magneti.Iyo ikoreshejwe mubushuhe bwa -55C ~ + 125C, iba yizewe cyane nko kurwanya ubushyuhe, kurwanya ubushuhe no kurwanya vibrasiya;
Mugihe kimwe, intera yagutse ya 60 ~ 160 irahari.Nuburyo bwiza bwo guhinduranya amashanyarazi asohoka choke coil, inductor ya PFC hamwe na inductor inductor, hamwe nibikorwa bihenze.
