Iningi lamasongo kazibuthe adinga ukupeyintwa ukuze kube lula ukuhlukanisa. Ngokuvamile, i-iron powder core ihlukaniswa ngemibala emibili. Ezisetshenziswa kakhulu ezibomvu/ezisobala, eziphuzi/ezibomvu, eziluhlaza/ezibomvu, eziluhlaza/oluhlaza okwesibhakabhaka kanye nophuzi/mhlophe. Indandatho ye-manganese eyinhloko ngokuvamile Ipendwe ngokuluhlaza, i-iron-silicon-aluminium ngokuvamile imnyama nokunye. Eqinisweni, umbala wendandatho kazibuthe ngemva kokudubula awuhlangene nokudaywa kopende olufuthwe kamuva, kuyisivumelwano nje embonini. Ngokwesibonelo, oluhlaza imele permeability high ring kazibuthe; imibala emibili imele i-iron powder core indandatho kazibuthe; black imele iron-silicon-aluminium magnetic ring, njll.
(1) Indandatho ephakeme kazibuthe
I-Magnetic ring inductors, kufanele sithi indandatho kazibuthe ye-nickel-zinc ferrite. Indandatho kazibuthe ihlukaniswe ibe yi-nickel-zinc kanye ne-manganese-zinc ngokuya ngezinto. Ukungena kazibuthe kwe-nickel-zinc ferrite magnetic ring materials okwamanje kusetshenziswa kusukela ku-15-2000. Izinto ezisetshenziswa kakhulu yi-nickel-zinc ferrite ene-permeability kazibuthe engu-100- Phakathi kuka-1000, ngokuya ngesigaba sokungena kazibuthe, ihlukaniswe ngezinto eziphansi zokungena kazibuthe. Ukungena kazibuthe kwendandatho kazibuthe ye-manganese-zinc ferrite kazibuthe ngokuvamile ingaphezu kuka-1000, ngakho-ke indandatho kazibuthe ekhiqizwe impahla ye-manganese-zinc ibizwa ngokuthi yindandatho kazibuthe ephezulu yokungena.
Amaringi kazibuthe e-nickel-zinc ferrite ngokuvamile asetshenziselwa izintambo ezihlukahlukene, amabhodi wesekethe, kanye nokulwa nokuphazamiseka kwemishini yekhompyutha. Amasongo kazibuthe e-Manganese-zinc ferrite angasetshenziswa ukwenza ama-inductors, ama-transformer, ama-filter cores, amakhanda kazibuthe nezinti zezinti. Ngokuvamile, lapho kuncishiswa ukukwazi ukungena, kuba banzi ububanzi befrikhwensi obusebenzayo; ukuphakama kokungena kokubalulekile, kuyancipha ububanzi befrikhwensi obusebenzayo.
(2) Indandatho ye-ayina eyimpushana

I-iron powder core igama elidumile le-magnetic material ferric oxide, elisetshenziswa kakhulu kumasekhethi kagesi ukuxazulula izinkinga zokuhambisana kuka-electromagnetic (EMC). Ekusetshenzisweni okungokoqobo, ezinye izinto ezihlukahlukene zizongezwa ngokuya ngezidingo ezihlukene zokuhlunga kumabhendi amafrikhwensi ahlukene.
Izinhlayiya zempuphu zikazibuthe zakuqala "zaziboshiwe" izinsimbi ezinozibuthe ezithambile ezenziwe nge-iron-silicon-aluminium alloy powders kazibuthe. Lo mgogodla we-iron-silicon-aluminium magnetic powder uvame ukubizwa ngokuthi "i-iron powder core". Inqubo yayo evamile yokulungiselela yilena: sebenzisa i-Fe-Si-Al alloy powder magnetic ukuze ubekwe isicaba ngokugaya ibhola futhi umbozwe ngongqimba oluvikelayo ngezindlela zamakhemikhali, bese wengeza cishe i-binder engu-15wt%, uhlanganise ngokulinganayo, bese ubumba futhi uqinise, bese uphatha ukushisa. (ukunciphisa ukucindezeleka) ukwenza imikhiqizo. Lo mkhiqizo wendabuko “we-iron powder core” usebenza kakhulu ku-20kHz∼200kHz. Ngenxa yokuthi anomthamo omkhulu kazibuthe wokuguquguquka wokugcwaliswa kwesikhala kunama-ferrite asebenza kubhendi yefrikhwensi efanayo, izici ezinhle ze-DC superposition, eduze ne-coefficient ye-magnetostriction enguziro, akukho msindo phakathi nokusebenza, ukuzinza okuhle kwefrikhwensi, kanye nesilinganiso esiphezulu samanani okusebenza. Isetshenziswa kakhulu ezingxenyeni ze-elekthronikhi njengama-high-frequency electronic transformers. Ukungalungi kwabo ukuthi ukugcwaliswa okungeyona-magnetic akukhiqizi kuphela ukuchithwa kwamagnetic, kodwa futhi kwenza indlela magnetic flux ingaqhubeki, futhi ukuchithwa kwamagnetic kwendawo kuholela ekwehleni kokungena kazibuthe.
I-iron powder core esanda kuthuthukiswa esebenza kahle kakhulu ihlukile kunendabuko ye-iron-silicon-aluminium powder core. Impahla eluhlaza esetshenziswayo akuyona i-alloy magnetic powder kodwa i-iron powder emsulwa ehlanganiswe nongqimba oluvikelayo. Inani le-binder lincane kakhulu, ngakho-ke ubukhulu be-magnetic flux bukhulu. ukwanda kobukhulu. Basebenza ebhendini yefrikhwensi emaphakathi nephansi engaphansi kuka-5kHz, ngokuvamile amakhulu ambalwa e-Hz, ephansi kakhulu kunemvamisa yokusebenza ye-FeSiAl magnetic powder cores. Imakethe okuhloswe ngayo ukufaka esikhundleni samashidi ensimbi ye-silicon yamamotho ngokulahleka kwawo okuphansi, ukusebenza kahle okuphezulu kanye nokuklama okulula kwe-3D.
I-Magnetic Ring Inductor
(3) Indandatho kazibuthe ye-FeSiAl
Indandatho kazibuthe ye-FeSiAl ingenye yezindandatho kazibuthe ezinezinga eliphezulu lokusetshenziswa. Ngamagama alula, i-FeSiAl yenziwe nge-aluminium-silicon-iron futhi ine-Bmax ephakeme ngokuqhathaniswa (i-Bmax iyisilinganiso esiphezulu esingu-Z endaweni enqamula ingxenye ye-magnetic core. Ukuminyana kwe-magnetic flux.), iphansi kakhulu kune-iron powder core kanye ne-high magnetic flux, ine-magnetostriction ephansi (umsindo ophansi), iyimpahla yokugcina amandla engabizi kakhulu, akukho ukuguga okushisayo, ingasetshenziswa ukufaka esikhundleni se-iron powder Ingqikithi izinzile kakhulu ekushiseni okuphezulu.
Izici eziyinhloko ze-FeSiAlZ ukulahlekelwa okuphansi kunezinsimbi ze-iron powder kanye nezici zamanje zokuchema kwe-DC. Intengo ayiyona ephakeme kakhulu, kodwa ayilona ephansi, uma iqhathaniswa ne-iron powder core ne-iron nickel molybdenum.
I-iron-silicon-aluminium powder core inezindawo ezinhle kakhulu zikazibuthe, ukulahleka kwamandla aphansi kanye nokuminyana okuphezulu kozibuthe. Uma isetshenziswa ebangeni lokushisa elingu -55C~+125C, inokwethenjelwa okuphezulu njengokumelana nezinga lokushisa, ukumelana nomswakama nokumelana nokudlidliza;
Ngasikhathi sinye, uhla olubanzi lokungena kwe-60 ~ 160 luyatholakala. Kuyisinqumo esingcono kakhulu sokushintsha ikhoyili yokuphuma kwamandla kagesi, i-PFC inductor kanye ne-resonant inductor, ngokusebenza kwezindleko eziphezulu.
