Neodymium lub tog raj kheej hlau nplaum rau muag - Muaj Zog Tsis tshua muaj Lub Ntiaj Teb Magnets | Fullzen

Feem ntau, ib lub hlau nplaum uas muaj lub tog raj kheej muaj ob lub ncej: ib lub ncej sab qaum teb thiab ib lub ncej sab qab teb. Cov ncej no nyob rau ntawm qhov kawg ntawm lub hlau nplaum uas muaj lub tog raj kheej. Cov kab sib nqus ntawm lub hlau nplaum tawm ntawm lub ncej sab qaum teb thiab rov qab mus rau hauv lub ncej sab qab teb, tsim ib lub voj voog kaw uas txhais lub teb sib nqus.

Kev taw qhia ntawm cov ncej yog txiav txim siab los ntawm kev sib dhos ntawm cov hlau nplaum sib nqus. Nyob rau hauv ib tug ntev lub tog raj kheej hlau nplaum, cov kev sib raug zoo ntawm cov domains feem ntau yog raws li axis ntawm lub tog raj kheej. Qhov no ua rau muaj qhov sib txawv ntawm ob tus ncej ntawm qhov kawg ntawm lub tog raj kheej.

Ua ib lub cylindrical hlau nplaum yuav tsum muaj ob peb kauj ruam, los ntawm kev xaiv cov khoom sib nqus tsim nyog rau shaping thiab magnetizing cov hlau nplaum. Ntawm no yog cov ntsiab lus dav dav ntawm cov txheej txheem:

Cov kauj ruam:

1. Kev Xaiv Khoom Siv
2. Kev Npaj Khoom Siv
3. Kev tsim
4. Sintering
5. Kev Siv Tshuab (Xaiv Tau)
6. Txheej (yeem)
7. Kev sib nqus
8. Kev Tswj Xyuas Zoo
9. Ntim Khoom

Nco ntsoov tias cov txheej txheem tuaj yeem sib txawv raws li hom hlau nplaum tshwj xeeb, cov khoom siv siv, thiab cov txheej txheem tsim khoom ntawm lub tuam txhab tsim cov hlau nplaum. Tsis tas li ntawd, cov hlau nplaum muaj zog xws li cov hlau nplaum neodymium tuaj yeem ua rau muaj kev phom sij vim lawv cov teb hlau nplaum muaj zog, yog li yuav tsum tau ceev faj txog kev nyab xeeb thaum txhua theem ntawm kev tsim khoom.

Lub zog sib nqus uas nyob ib puag ncig lub hlau nplaum cylindrical, zoo li txhua lub hlau nplaum, muaj cov kab sib nqus uas nthuav tawm ntawm lub hlau nplaum sab qaum teb thiab rov qab mus rau nws sab qab teb. Tus qauv tseeb ntawm lub zog sib nqus nyob ntawm lub hlau nplaum lub duab, qhov loj me, thiab kev coj ua ntawm lub zog sib nqus.

Rau cov hlau nplaum cylindrical, yog tias nws yog magnetized raws nws qhov ntev (axially magnetized), cov kab hlau nplaum yuav feem ntau ua raws li cov qauv no:

1. Sab nraum lub Magnet
2. Nruab nrab ntawm Cov Nceeg Vaj
3. Sab hauv lub Magnet

Qhov ceev thiab kev taw qhia ntawm cov kab hlau nplaum sib nqus muab peb cov ntaub ntawv hais txog lub zog thiab kev taw qhia ntawm cov hlau nplaum. Cov hlau nplaum yog qhov muaj zog tshaj plaws nyob ze ntawm cov hlau nplaum cov ncej thiab ua tsis muaj zog thaum koj txav mus deb ntawm cov hlau nplaum.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov kab ntawm lub zog sib nqus yog ib qho kev sawv cev pom tau zoo ntawm lub zog sib nqus, tab sis qhov tseeb, lub zog sib nqus yog peb-seem thiab tuaj yeem nyuaj heev. Tus cwj pwm ntawm lub zog sib nqus tuaj yeem raug cuam tshuam ntxiv los ntawm cov khoom nyob ze, qhov muaj lwm cov hlau nplaum, thiab ib puag ncig.
