High-permeability cov ntaub ntawv xa mus rau ferromagnetic cov ntaub ntawv nrog ib tug permeability ntawm txog 100 los yog ntau tshaj. Kuj hu ua mos magnetic khoom. Cov ntaub ntawv zoo li no yuav tsum muaj cov permeability siab, siab saturation sib nqus induction, siab tsis kam, tsis tshua muaj kev poob siab, thiab kev ruaj ntseg zoo. Ntawm lawv, siab permeability thiab poob qis yog qhov tseem ceeb tshaj plaws.
Feem ntau siv hlau mos magnetic cov ntaub ntawv feem ntau yog tsim los ntawm hlau, cobalt, npib tsib xee, peb lub ntsiab ferromagnetic, los yog ib tug hlau ntawm lawv, los yog ib tug ua ke ntawm ob los yog peb ntawm lawv, los yog ib tug ua ke ntawm ob los yog peb ntawm lawv. Rau lub hauv paus no, kev sib xyaw ua ke ntawm lwm cov ntsiab lus ntxiv, thiab cov qauv feem ntau yog polycrystalline lossis ib qho siv lead ua.
Raws li txoj kev siv, nws tau muab faib ua hmoov core thiab daim kab xev qhov txhab, feem ntau suav nrog cov ntaub ntawv hauv qab no:
1. Hlau hmoov core (nrog Fe-Si-Al, Fe, FeSi, High flux hmoov core, Mpp core) yog flattened los ntawm pob milling thiab coated nrog insulating txheej los ntawm cov txheej txheem tshuaj, ces ntxiv txog 15wt feem pua binder, sib tov tom qab uniform molding thiab kho, thiab thaum kawg kev kho cua sov (kev ntxhov siab nyem) ua cov khoom. Cov khoom siv "hlau hmoov core" cov khoom no feem ntau ua haujlwm ntawm 20kHz∼200kHz. )
2. Cov hlau ntshiab (cov ntsiab lus carbon tsawg dua li feem pua, suav nrog electromagnetic ntshiab hlau, electrolytic hlau, carbonyl hlau. Feem ntau siv rau hauv kev tsim cov electromagnet cores, ncej khau, relays thiab hais lus, sib nqus permeability, magnetic shields, thiab lwm yam.
3. Silicon steel daim ntawv (Fe-Si alloy) yog cov khoom siv hlau uas muaj me me ntawm silicon (tsawg dua lossis sib npaug li 4.5 feem pua) ntxiv rau cov hlau ntshiab uas tsis tshua muaj cov ntsiab lus carbon, feem ntau hu ua silicon steel. Ntxiv silicon tuaj yeem txhim kho qhov kev tiv thaiv thiab siab tshaj plaws sib nqus permeability ntawm hlau. , txo coercivity, core poob thiab magnetic aging. Feem ntau, nws saturation magnetic induction intensity yog 20000Gs. Nws muaj cov yam ntxwv ntawm cov khoom siv qis thiab yooj yim tsim thiab ua. Nws yog tsuas yog siv los ua hlau cores rau ntau yam transformers, motors thiab generators, thiab yog dav siv nyob rau hauv lub hwj chim motors thiab lwm yam lag luam. Lub ntiaj teb silicon steel ntawv ntau lawm suav txog ib feem pua ntawm tag nrho cov hlau tsim. Raws li seb nws yog oriented, nws muab faib ua ib leeg-oriented silicon steel ntawv thiab non-oriented silicon steel ntawv. Lub thickness ntawm ib daim ntawv silicon steel feem ntau yog 0.2 ~ 0.35mm. Thaum siv qis dua 400Hz, nws tsim nyog xaiv lub thickness ntawm 0.1 hli. Lub thinner ntawm silicon steel ntawv, tus nqi siab dua.
4. Nickel-raws li alloys feem ntau yog xa mus rau hlau-nickel alloys, thiab cov ntsiab lus nickel yog nyob rau hauv 30 feem pua rau 90 feem pua. Cov qib 1J50, 1J79, thiab lwm yam. Lub saturation sib nqus induction siv ntawm 1J50 yog me ntsis qis dua li ntawm silicon steel ntawv, tab sis qhov sib nqus permeability (37.5 ~ 125mH / m) yog kaum ob lub sij hawm ntawm silicon steel ntawv, thiab cov hlau poob. tseem tsawg dua ib nrab ntawm cov ntawv silicon steel. Kev siv ntawm inductors yog ntau dua.
Amorphous Nanocrystalline Mos Sib Nqus Alloy
Amorphous alloy yog cov khoom siv alloy nrog amorphous disordered kev npaj tau los ntawm kev ntxiv cov ntsiab lus vitrifying (silicon, boron, carbon, thiab lwm yam) thaum lub sij hawm smelting txheej txheem ntawm hlau mos magnetic, uas muaj peev xwm khaws tau siab saturation ntawm hlau mos magnetic. Lub zog sib nqus induction thiab siab sib nqus permeability txo eddy tam sim no poob, thiab tau hloov silicon hlau thiab npib tsib xee-raws li alloys nyob rau hauv nruab nrab thiab tsawg zaus lub hwj chim lag luam.
Peb cov khoom siv sib nqus sib nqus (SMC) yog cov khoom siv hlau hmoov hlau uas yog thawj qeb. Tom qab qhov saum npoo ntawm cov hlau sib nqus hmoov yog qhwv nrog ib qho nruab nrab insulating, cov khoom siv hmoov yog tau los ntawm nias cov txheej txheem hmoov metallurgy rau hauv cov duab xav tau.
