Dab tsi yog qhov siv hlau nplaum (micro)?
Tam sim no, feem ntau cov neeg tsav tsheb siv neodymium hlau boron hlau nplaum ua cov hlau nplaum thiab cov hlau cav hlau. Ib txhia neeg tsav tsheb kuj tseem siv cov hlau zeb hlau cobalt samaruas thiab cov hlau nplaum ferrites ua cov hlau nplaum loj.
1, samarium cobalt muaj kub tsis kam (400 ° C), xim ntawm cov hlau yog kaj lug, tus nqi siab, kev saib xyuas, micro-point yog siv tsis tshua xyaw samarium cobalt.
2, lub ferrite ruaj khov, vim tias qhov kub ua haujlwm tsis txaus (li ntawm 400 ° C) no qhov zoo tshaj qhov tshaj li NdFeB, tab sis! Nws yog tsim nyog yuav ua rau lub micro-motor txuam ntawm ferrite, thiab nws yog exquisite, tus txheej txheem raug siab, thiab cov seem seem kuj yog vim nws yog yooj yim tawg lossis hnav thiab rhuav.
3. Lub tshuab hlau nplaum hlau uas siv lub tshuab hlau uas siv cov hlau nplaum hlau raws li lub cav hlau uas muaj hlau nplaum raws li lub cav hlau nplaum loj me, lub cev nyhav, siab torque-inertia piv siab, qhov kev ua haujlwm siab tshaj tawm, kev muaj zog thiab ceev / lub luj, kev pib siab zog thiab kev txuag hluav taws xob. Cov duab ntawm lub cev muaj hlau nplaum thiab lub cav hlau nplaum feem ntau yog cov nplais ntsej muag, lub nplhaib los yog lub plhaub taum, thiab siv tau rau hauv cov cav ntoo sib txawv, xws li cov hlau nplaum hluav taws xob, AC motors, DC motors, linear motors, brushless motors, thiab cov zoo li .
Cov nram no piav qhia txog NdFeB.
(1) Cov neeg siv feem ntau siv lub attraction thiab kev tshem tawm ntawm kev sib tsoo ntawm cov hlau nplaum. Feem ntau, ib hom kab hlau nplaum uas muaj hlau nplaum zoo li lub nplhaib tau xaiv los ua ib lub nplhaib, thiab NdFeB sintered yog ib qho khoom siv anisotropic, uas tsis tuaj yeem raug tsim ua ib tus neeg tau txais kev pab ib zaug. Ib qho kev xav tau me ntsis ntxiv yog qhov xav tau.
(2) NdFeB tseem raug muab faib ua cov NdFeB thiab NdFeB sintered, thaum NdFeB muaj ntau dua los ntawm kev lag luam. Tam sim no, qee cov chaw lag luam tseem tuaj yeem ua tus radial magnetization ntawm cov NdFeB hlau nplua nuj, tab sis muaj ntau ntau rau cov qib ntawm cov qib (lub zog sib nqus), thiab cov khoom sib nqus kuj muaj qhov yuav tsum ua kom ruaj khov thiab sib luag, thaum pwm coil Thiab cov hlau nplaum magnetizing yog kim, yog tias tsis yog cov khoom lag luam ruaj khov, cov tuam txhab tsawg heev yuav xaiv cov nyiaj NdFeB. Tab sis yog tias koj lub tsev yog ib lub tuam txhab uas tsim cov tshuab zoo tshaj tawm, ces daim ntawv cog lus NdFeB yog qhov kev xaiv thawj zaug rau koj cov hlau nplaum.
