Ferrite
Ferrite hlau nplaum yog cov hlau nplaum tas mus li feem ntau ua los ntawm SrO lossis BaO thiab Fe2O3 ua raw khoom. Ntxiv rau qhov muaj zog tiv thaiv demagnetization kev ua tau zoo, cov khoom siv hlau nplaum no kuj muaj qhov zoo ntawm tus nqi qis. Ferrite hlau nplaum yog tawv thiab nkig, thiab yuav tsum tau tshwj xeeb machining txheej txheem. Peb lub tuam txhab tsuas yog tsim lawv los ntawm cov thev naus laus zis ceramic. Vim tias cov hlau nplaum ferrite muaj qhov kub thiab txias tsis kam, tus nqi qis, thiab kev ua haujlwm nruab nrab, lawv tau dhau los ua cov hlau nplaum siv dav tshaj plaws. Ntau yam ntawm cov hlau nplaum ruaj khov.
Txoj kev tsim khoom
Ferrite hlau nplaum tau muab faib ua ob hom: isotropic thiab anisotropic, thiab txoj kev tsim khoom yog compression molding. Peb cov cuab yeej tsim khoom yog tag nrho cov tuaj ntawm Nyij Pooj, nrog kev ua haujlwm siab, kom cov khoom siv lub neej ntev dua thiab qhov sib npaug zoo dua. Vim yog cov cuab yeej siv thev naus laus zis ntau lawm, nws tuaj yeem muab cov neeg siv khoom zoo dua.
Isotropic hlau nplaum
Lub npe hu ua isotropic hlau nplaum tsis muaj kev taw qhia. Nws yog tsim los ntawm hmoov metallurgy nrog cov khoom zoo, tab sis tsis muaj kev sib nqus teb. Txwv tsis pub. Tab sis qhov tsis zoo yog tias kev sib nqus flux ntom tsis muaj zog, thiab qee cov ntawv thov yuav tsis tuaj yeem ua tau raws li cov neeg siv khoom sib nqus.
Anisotropic hlau nplaum
Lub npe hu ua anisotropic hlau nplaum, tsuas yog rov qab rau cov hlau nplaum isotropic, muaj kev taw qhia. Nws yog ua los ntawm cov hmoov zoo thaum tsim, thiab kev npaj ntawm high-voltage magnetic teb yog siv los ua cov hlau nplaum ib qho ruaj khov axial lossis radial kev taw qhia. Tom qab cov hlau nplaum tiav lawm, tsuas yog tuaj yeem sib nqus raws li qhov kev npaj ntawm cov hlau nplaum thaum lub sij hawm molding, thiab cov kev taw qhia magnetization uas tau kho tsis tuaj yeem hloov pauv. Qhov zoo yog muaj zog sib nqus thiab siab coercive quab yuam, uas yog lub ntsiab ntawm lub lag luam ferrite hlau nplaum.
Sintered ferrite cov hlau nplaum ruaj khov yog cov khoom siv tseem ceeb rau kev tsim cov motors ntawm ntau qhov chaw ntawm lub tsheb. Nrog rau kev txhim kho txuas ntxiv ntawm tsheb thev naus laus zis, ntau yam kev ua haujlwm ntawm lub tsheb tau maj mam txhim kho, thiab tus nqi ntawm cov khoom siv tsis tshua muaj hauv ntiaj teb tau nce siab hauv xyoo tas los no. Vim yog tus nqi qis ntawm ferrite, tus nqi ntawm ferrite siv Nws kuj tseem yuav txhim kho tau zoo, thiab yuav muaj ntau daim ntawv thov kev lag luam thiab kev cia siab.
