Dab tsi yog Cov Khoom Siv Sib Nqus Soft

Cov khoom sib nqus mos, nyob rau hauv qhov kev txiav txim ntawm magnetization, Hc yuav tsis tshaj 1000A / m. Nyob rau hauv lub magnetic teb, sab nraud magnetic teb nrog lub zog sib nqus tsawg tshaj plaws tuaj yeem raug xaiv kom ua tiav qhov siab tshaj plaws magnetization. Cov ntaub ntawv sib nqus mos yog cov yam ntxwv los ntawm kev sib nqus yooj yim thiab tseem pab txhawb kev degradation ntawm magnetic force. Nws yog dav siv nyob rau hauv ntau lub Hoobkas khoom, xws li cov khoom siv hluav taws xob.

Cov ntaub ntawv sib nqus tau siv thawj zaug hauv kev lag luam, yos rov qab mus rau lub xyoo pua puv 19, tab sis nrog kev txhim kho ntawm cov cuab yeej siv hluav taws xob, cov khoom siv hlau nplaum tau pib pom cov kev hloov pauv. Cov pa roj carbon tsawg yog siv los tsim cov tshuab tsim khoom thiab cov khoom siv, thiab qee cov hlau uas muaj cov khoom siv hauv cov khoom sib nqus ntawm cov khoom siv hauv xov tooj los ua kom cov kab hluav taws xob ruaj khov. Nrog rau kev tsim cov thev naus laus zis, kev txhim kho ntawm cov ntaub ntawv silicon steel tau maj mam hloov cov khoom siv qis carbon steel, txhim kho cov khoom lag luam thiab txo kev siv zog. Txog tam sim no, silicon steel los xij yog cov khoom siv sib nqus uas siv ntau tshaj plaws hauv kev lag luam fais fab. Kev txhim kho thev naus laus zis tsis yog tsuas yog txhim kho kev ua tau zoo ntawm cov khoom sib nqus mos, tab sis kuj tseem ua rau kev tsim khoom ntawm ntau yam khoom tuaj yeem tshwm sim pem hauv ntej ntawm peb. Niaj hnub no, cov kws tshaj lij tau tshawb fawb ntau dua thiab txhim kho ntawm cov khoom sib nqus mos, ua ke cov khoom siv hlau nplaum tshiab, uas tau siv thiab ua ntau yam.

Kev ua tau zoo ntawm cov khoom sib nqus mos

1. Cov khoom siv sib nqus mos tuaj yeem siv tau rau ntau qhov xwm txheej, yog li lawv muaj cov khoom sib txawv, feem ntau nyob rau hauv lub xeev ntawm static tam sim no los yog tsawg zaus. Nyob rau hauv qhov tsawg-frequency magnetic teb, mos magnetic cov ntaub ntawv yuav txhim khu lawv magnetic quab yuam los ntawm tsawg kawg yog 80%. Cov ntaub ntawv sib nqus mos yuav tsum muaj qhov pib sib nqus conductivity thiab siab sib nqus saturation. Qhov me me ntawm cov hlau nplaum retrieval tas li, qhov kev puas tsuaj ntau rau lub tshuab yuav raug zam, thiab cov khoom siv hlau lossis hlau yuav tsum tau siv.

Yog hais tias nws nyob rau hauv alternating magnetic teb, lub hysteresis voj nyob rau hauv cov khoom yuav tsum me me. Vim tias qhov sib nqus poob yog proportional rau qhov loj thiab thaj tsam ntawm lub voj hysteresis. Thaum cov tam sim no nyob rau hauv ib tug tsawg-frequency xeev, mos magnetic ntaub ntawv pib yuav tsum tau high magnetic conductivity, ua rau lub magnetization muaj zog. Txawm li cas los xij, thaum siv ntau zaus, qhov saturation ntawm cov khoom siv hlau nplaum yuav raug txwv. Yog hais tias siv ntawm ultra-high frequencies, eddy tam sim no poob yuav proportional rau lub square ntawm magnetization zaus. Nyob rau hauv cov ntaub ntawv no, cov khoom siv sib nqus mos yuav tsum muaj kev tiv thaiv siab, thiab cov khoom siv feem ntau yog ferrite.
