Yog vim li cas rau kev ua haujlwm tsis zoo ntawm Bonded Magnets

Peb txhua tus paub tias cov hlau nplaum sib txuas muaj cov khoom sib nqus tsis zoo dua li cov hlau nplaum neodymium sintered, tab sis yog vim li cas? Koj puas tuaj yeem qhia kuv ib lossis ob qho, thiab hnub no kuv yuav qhia koj ob qho laj thawj rau kev ua haujlwm tsis zoo ntawm cov hlau nplaum sib txuas.

Ua ntej, cov hlau nplaum sib txuas yog isotropic, txhais tau hais tias lub zog hlau nplaum yog tib yam (thiab cov duab nyob ntawm) tsis hais txog kev taw qhia ntawm kev sib nqus ntawm cov hlau nplaum. Tab sis cov hlau nplaum sintered yog cov hlau nplaum anisotropic. Nyob rau hauv cov txheej txheem ntawm sintered hlau nplaum, muaj cov txheej txheem hu ua magnetic teb orientation, yog li tsuas yog cov kev taw qhia ntawm magnetization orientation yuav magnetized thiab muaj ib tug siab magnetic teb lub zog, lwm cov lus qhia tsis tau magnetized thiab tsis muaj magnetic quab yuam. Raws li txoj kev xav, qhov remanence ntawm cov hlau nplaum isotropic tsuas yog ib nrab ntawm cov hlau nplaum anisotropic, vim tias cov khoom siv hluav taws xob yog proportional rau square ntawm remanence, yog li anisotropic magnetic kev ua tau zoo ntawm cov hlau nplaum anisotropic yog plaub npaug ntawm cov hlau nplaum isotropic.

Qhov thib ob, txij li cov hlau nplaum sib txuas muaj cov nplaum nplaum, qhov tseeb qhov ceev tsuas yog 80 feem pua ​​​​ntawm cov theoretical ntom ntom, yog li cov khoom sib nqus ntawm cov hlau nplaum sib nqus yuav txo qis li 30 feem pua.
