Kev tshuaj xyuas ntawm Magnetic Materials Fundamentals thiab Applications of Soft Magnetic Materials

 

Cov khoom siv hlau nplaum feem ntau yog tsim los ntawm ferromagnetic los yog ferrimagnetic tshuaj. Raws li kev cuam tshuam ntawm sab nraud magnetic teb, lawv nthuav tawm cov lus teb magnetization, uas feem ntau tshwm sim los ntawm magnetization curves (B-H lossis M-H nkhaus). Cov nkhaus no nthuav tawm cov yam ntxwv tseem ceeb uas tsis yog kab, feem ntau tshwm sim raws li kev sib nqus saturation thiab hysteresis cuam tshuam. Thaum cov ntaub ntawv sib nqus tau ntxiv dag zog rau ib qho twg, cov khoom sib nqus hauv cov khoom zoo li yuav tsum tau ua kom tiav, ncav cuag saturation magnetic induction. Piv txwv li, thaum lub magnetic teb tsis muaj zog los yog txawm dhau los ua xoom, cov khoom khaws cia ib qho nyiaj ntawm cov hlau nplaum remanent. Qhov tshwm sim no tshwj xeeb yog qhov tseem ceeb hauv ntau yam Electromagnet Core designs.

 

Cov kev ua haujlwm tseem ceeb ntawm cov khoom sib nqus mos muaj xws li saturation magnetic induction (Bs), remanent magnetic induction (Br), coercivity (Hc), thiab permeability (μ). Ntawm cov no, tsis tshua muaj coercivity thiab siab permeability yog cov cim tseem ceeb rau kev soj ntsuam cov khoom ua tau zoo, cuam tshuam ncaj qha rau cov lus teb ceev thiab lub zog noj ntawm relay hlau cores hauv relays. Tsis tas li ntawd, Curie qhov kub thiab txias txiav txim siab cov khoom ruaj khov ntawm qhov kub thiab txias, thaum sib nqus poob cuam tshuam rau cov cuab yeej ua haujlwm thiab kub nce qib. Hauv kev siv engineering, cov khoom sib nqus yuav tsum tau tsim kom haum rau cov khoom siv hluav taws xob, xws li voltage, tam sim no, thiab zaus yam ntxwv. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov khoom siv precision xws li Core rau Electromagnetic Relay. Kev xaiv cov khoom tsim nyog, kev tsim qauv, thiab kev ua haujlwm kom zoo yog qhov tseem ceeb rau kev ua tiav qib siab -cov khoom siv sib nqus.

 

 

 

Txoj kev loj hlob ntawm cov khoom siv hlau nplaum yog ze ze rau kev nce qib hauv kev lag luam hluav taws xob thiab hluav taws xob technology. Los ntawm thaum ntxov qis- cov ntaub ntawv carbon steel mus rau daim ntawv thov ntawm silicon steel los xij, thiab tom qab ntawd mus rau siab -permeability permalloys thiab niaj hnub amorphous thiab nanocrystalline cov ntaub ntawv, lawv cov kev ua tau zoo tsis tu ncua, thiab kev poob tau raug txo qis.

Los ntawm cov txheej txheem tsim thiab kev tsim cov kev xav, cov khoom siv hlau nplaum tuaj yeem muab faib ua ob pawg loj: hmoov- cov ntaub ntawv tseem ceeb thiab ribbon- cov hlau nplaum. Hmoov- cov ntaub ntawv tseem ceeb feem ntau yog tsim los ntawm kev nias cov khoom sib nqus hlau nplaum thiab muaj cov yam ntxwv zoo heev - zaus, thaum ribbon- cov ntaub ntawv mob yog tsim los ntawm stacking lossis winding nyias strips thiab tsim nyog rau qis - rau - nruab nrab zaus thiab siab - fais fab kev siv. Cov ntaub ntawv no tau siv dav hauv Soft Magnetic Iron Cores rau Relays thiab ntau yam khoom siv hluav taws xob.

 

 

 

Sib nqus hmoov cores yog ib yam khoom ntawm cov khoom sib nqus sib nqus, tsim los ntawm nias ferromagnetic hmoov nrog ib qho nruab nrab insulating. Vim cov txheej txheej insulating ntawm cov khoom, eddy tam sim no poob tau zoo suppressed, ua rau lawv haum rau nruab nrab - mus rau - cov ntawv thov ntau zaus. Lawv muaj qhov permeability tsawg tab sis kev ruaj ntseg zoo, ua rau lawv tshwj xeeb tshaj yog haum rau inductors thiab lim circuits, nthuav tawm cov lus teb zoo heev hauv cov ntawv thov xws li Relay Coil Cores.

 

Hlau hmoov cores, raws li tus nqi qis tshaj - hom magnetic hmoov cores, muaj siab saturation magnetic induction, ua rau lawv tsim nyog rau nqi - rhiab fais fab kev thov; thaum permalloy hmoov cores muab kev poob qis thiab zoo heev kub stability, ua rau lawv haum rau siab -cov khoom siv hluav taws xob precision. Ferro-silicon-aluminium hmoov cores tawm tsam qhov sib npaug ntawm kev ua tau zoo thiab tus nqi thiab tau siv dav hauv cov khoom siv hluav taws xob lim dej thiab lub zog kho qhov system. Cov ntaub ntawv no tau maj mam tsim cov txheej txheem kev thov hauv thaj chaw ntawm Hluav Taws Xob Pure Iron Cores.

 

 

 

Mos magnetic ferrites yog ib chav kawm ntawm cov hlau oxide-raws li cov khoom siv hlau nplaum ceramic nrog kev tiv thaiv siab thiab zoo siab - zaus ua haujlwm. Raws li lawv muaj pes tsawg leeg, ferrites tuaj yeem faib ua Mn-Zn, Ni-Zn, thiab lwm yam. Mn-Zn ferrites haum rau tsawg- zaus, siab- siv fais fab, thaum Ni-Zn ferrites yog qhov tsim nyog rau kev sib txuas lus siab.

 

Cov ntaub ntawv ferrite tau siv dav hauv kev hloov cov khoom siv hluav taws xob, electromagnetic compatibility (EMI), thiab cov khoom siv hluav taws xob vim lawv qhov poob qis, ruaj khov siab, thiab muaj peev xwm ntau lawm. Hauv cov khoom siv hluav taws xob niaj hnub no, ferrite cores tau dhau los ua cov khoom siv tseem ceeb hloov cov hmoov cores, ua kom muaj kev sib raug zoo hauv Pure Iron Core daim ntaub ntawv.
