Zvindori zvemagineti zvakawanda zvinoda kupendwa kuti zviite mutsauko. Kazhinji, iyo iron poda core inosiyaniswa nemavara maviri. Idzo dzinowanzo shandiswa ndeye tsvuku / pachena, yero / tsvuku, yegirini / tsvuku, yegirini / yebhuruu uye yero / chena. Iyo manganese musimboti mhete inowanzo Pendirwa girini, iron-silicon-aluminium inowanzova nhema uye zvichingodaro. Muchokwadi, iyo ruvara rwemagineti mhete mushure mekupfura haina chekuita nekudhayiwa kwepende yakapfapfaidzwa gare gare, ingori chibvumirano muindasitiri. Semuenzaniso, girini inomiririra yakakwirira permeability magineti mhete; maviri-ruvara anomiririra iron poda core magnetic ring; dema inomiririra iron-silicon-aluminium magineti mhete, nezvimwe.
(1) High magineti permeability mhete
Magnetic ring inductors, tinofanira kutaura nickel-zinc ferrite magnetic ring. Iyo magineti mhete yakakamurwa kuita nickel-zinc uye manganese-zinc zvinoenderana nechinhu. Iyo magineti permeability yenickel-zinc ferrite magineti mhete zvinhu parizvino inoshandiswa kubva pa15-2000. Izvo zvinowanzo shandiswa ndeye nickel-zinc ferrite ine magineti permeability ye100- Pakati pe1000, zvinoenderana neiyo magineti permeability classification, yakakamurwa kuita yakaderera magineti ekugadzirisa zvinhu. Iyo magineti permeability ye manganese-zinc ferrite magineti ring material inowanzo pfuura 1000, saka magineti mhete inogadzirwa nemanganese-zinc zvinhu inonzi yakakwira permeability magineti mhete.
Nickel-zinc ferrite magineti mhete anowanzo shandiswa kune akasiyana waya, mabhodhi edunhu, uye anti-kupindira mumidziyo yemakomputa. Manganese-zinc ferrite magineti mhete inogona kushandiswa kugadzira inductors, transformers, filter cores, magineti misoro uye antenna tsvimbo. Kazhinji, iyo yakaderera iyo zvinhu permeability, iyo yakafara iyo inoshanda frequency renji; iyo yakakwira kupenya kwezvinhu, ndiko kudikitira kunoshanda frequency renji.
(2) Iron powder core ring

Iron poda core izwi rakakurumbira remagineti zvinhu ferric oxide, rinonyanya kushandiswa mumaseketi emagetsi kugadzirisa matambudziko emagetsi emagetsi (EMC). Mukushanda kunoshanda, zvimwe zvakasiyana-siyana zvinowedzerwa zvinoenderana neakasiyana mafirita zvinodiwa mumabhendi akasiyana-siyana.
Ekutanga magineti poda cores aive "akasungwa" simbi yakapfava magineti cores yakagadzirwa nesimbi-silicon-aluminium alloy magineti poda. Iyi iron-silicon-aluminium magnetic powder core inowanzonzi "iron powder core". Magadzirirwo ayo anowanzo kugadzirira ndeaya: shandisa Fe-Si-Al alloy magineti poda kuti igadzwe nekugaya bhora uye yakaputirwa ne insulating layer nemakemikari nzira, wobva wawedzera nezve 15wt% binder, sanganisa zvakaenzana, wozoumba mold uye kusimba, uyezve kupisa kurapwa. (stress relief) kugadzira zvigadzirwa. Ichi chinyakare "iron poda core" chigadzirwa chinonyanya kushanda pa20kHz∼200kHz. Nekuti ivo vane yakakwira yakanyanya saturation magineti flux density pane maferrites anoshanda mune imwechete frequency bhendi, yakanaka DC superposition maitiro, padyo ne zero magnetostriction coefficient, hapana ruzha panguva yekushanda, yakanaka frequency kugadzikana, uye yakakwirira kuita-mutengo reshiyo. Inoshandiswa zvakanyanya muzvikamu zvemagetsi zvakadai sepamusoro-frequency electronic transformers. Zvavakashata ndezvekuti iyo isiri-magnetic kuzadza haingoburitse magineti dilution, asi zvakare inoita kuti iyo magineti flux nzira isarambe, uye demagnetization yenzvimbo inotungamira mukudzikira kwemagineti permeability.
Iyo ichangobva kugadzirwa yakakwirira-inoshanda simbi poda core yakasiyana neyechinyakare iron-silicon-aluminium magnetic poda core. Iyo mbishi inoshandiswa haisi alloy magineti poda asi yakachena iron poda yakavharwa ne insulating layer. Huwandu hwebinder hudiki kwazvo, saka iyo magineti flux density yakakura. kuwedzera muhukuru. Ivo vanoshanda pakati-yakaderera frequency bhendi pazasi 5kHz, kazhinji mazana mashoma Hz, iyo yakaderera zvakanyanya pane yekushanda frequency yeFeSiAl magineti poda cores. Musika unotarirwa kutsiva silicon simbi mashiti emotor nekurasikirwa kwayo kwakaderera, kushanda kwakanyanya uye kureruka kwe3D dhizaini.

(3) FeSiAl magnetic mhete
Iyo FeSiAl magineti mhete ndeimwe yemagineti mhete ine yakanyanya kushandiswa mwero. Nemashoko akapfava, FeSiAl inoumbwa nealuminium-silicon-iron uye ine Bmax yakati wandei (Bmax ndiyo avhareji yeZ yepamusoro pane mhiri-chikamu nzvimbo yemagnetic core. Magnetic flux density.), kurasikirwa kwayo kwemagineti ndeyekurasikirwa kwayo. yakaderera zvakanyanya kupfuura iron poda core uye yakakwirira magineti flux, ine yakaderera magnetostriction (yakaderera ruzha), inodhura-inodhura simba rekuchengetedza zvinhu, isina kuchembera inopisa, inogona kushandiswa kutsiva iron upfu Nheyo yacho yakagadzikana zvakanyanya pakupisa kwakanyanya.
Iwo makuru maficha eFeSiAlZ kurasikirwa kwakaderera pane iron poda cores uye yakanaka DC bias ikozvino maitiro. Mutengo wacho hausi wepamusoro-soro, asi kwete wakaderera, uchienzaniswa nesimbi poda core uye iron nickel molybdenum.
Iyo iron-silicon-aluminium magineti poda core ine yakanakisa magineti uye magineti zvivakwa, yakaderera simba kurasikirwa uye yakakwira magineti flux density. Kana ichishandiswa mutembiricha ye -55C ~ + 125C, ine yakakwirira kuvimbika senge tembiricha kuramba, humidity kuramba uye vibration kuramba;
Panguva imwecheteyo, yakawanda permeability siyana ye60 ~ 160 inowanikwa. Iyo ndiyo yakanakisa sarudzo yekuchinja magetsi ekupa inoburitsa coil, PFC inductor uye resonant inductor, ine yakakwira mutengo kuita.
