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

Lub tog raj kheej hlau nplaum feem ntau muaj ob tug ncej: sab qaum teb ncej thiab sab qab teb ncej. Cov ncej no nyob ntawm qhov kawg ntawm cov hlau nplaum cylindrical. Cov kab hluav taws xob sib nqus ntawm cov hlau nplaum tawm ntawm sab qaum teb ncej thiab voj rov qab mus rau sab qab teb ncej, tsim ib lub voj kaw uas txhais tau tias cov hlau nplaum.

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
2. Kev npaj khoom siv
3. Kev tsim
4. Sintering
5. Machining (yeem)
6. Txheej (yeem)
7. Magnetization
8. Kev Tswj Xyuas Zoo
9. Ntim

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

Cov hlau nplaum nyob ib ncig ntawm lub cylindrical hlau nplaum, zoo li txhua yam hlau nplaum, muaj cov kab hlau nplaum uas nthuav tawm sab nraud los ntawm cov hlau nplaum sab qaum teb thiab voj rov qab rau hauv nws sab qab teb ncej. Cov qauv tseeb ntawm cov hlau nplaum yog nyob ntawm cov hlau nplaum cov duab, qhov loj, thiab cov kev taw qhia magnetization.

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 Magnet
2. Nruab nrab ntawm Cov Nceeg Vaj
3. Sab hauv 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 hlau nplaum sib nqus yog qhov muaj txiaj ntsig zoo ntawm cov hlau nplaum, tab sis qhov tseeb, cov hlau nplaum sib nqus yog peb-dimensional thiab tuaj yeem ua tau zoo heev. Tus cwj pwm ntawm cov hlau nplaum tuaj yeem cuam tshuam ntxiv los ntawm cov khoom nyob ze, muaj lwm cov hlau nplaum, thiab ib puag ncig ib puag ncig.
