Yuav Ua Li Cas Cov Hlau nplaum muaj zog

Cov hlau nplaum muaj zog ua li cas, nyob zoo, koj puas nkag siab? Nd-Fe-B (neodymium-hlau-boron) sintered hlau nplaum yog cov khoom tseem ceeb hauv kev tsav tsheb ntawm hybrid thiab hluav taws xob tsheb. Piv nrog rau lwm cov hlau nplaum, cov hlau nplaum neodymium tsis yog cov hlau nplaum muaj zog txaus rau lub zog ntawm lub tsheb, tab sis kuj txo lub cev muaj zog rau qhov loj me uas haum rau kev siv tsheb.

Yog li, koj puas paub tias qhov NdFeB muaj zog hlau nplaum no ua li cas? Nws koom nrog crushing ib qho alloy uas muaj cov khoom tsim nyog rau hauv cov khoom, agglomerating cov hais mus rau hauv ib tug duab, thiab ces sintering lawv. Tom qab ntawd txiav mus rau qhov loj me kom tiav. Cov txheej txheem ib txwm zoo li ua ncuav mog qab zib.

Tau kawg, nws tsis yog yooj yim heev nyob rau hauv qhov tseeb loj ntau lawm ntawm high-zoo NdFeB muaj zog hlau nplaum. Nws yuav siv sij hawm ntau lub sij hawm los tsim tsis tau tsuas yog lub uniformity ntawm cov hais mus rau ib tug loj ntawm 3 mus rau 5 μm, tab sis kuj lub uniformity ntawm cov duab thiab cov cua kub txoj kev thaum lub sij hawm sintering. "Los ntawm accumulating ib tug ntau ntawm me me technologies, peb tau mus txog lub tswv yim theem hnub no" (tus kws kho mob koom nyob rau hauv txoj kev loj hlob ntawm neodymium hlau nplaum).

Piv txwv li, "kev tsim cov txheej txheem nyob rau hauv ib tug sib nqus teb", uas yog ua tom qab lub alloy yog pulverized rau 3 mus rau 5 μm, yog ib tug ntawm lawv. Cov kauj ruam no yog taw qhia cov pulverized micropowder (micromagnet). Txoj kev taw qhia ntawm no yog hais txog kev sib koom ua ke ntawm cov kev taw qhia magnetization ntawm micropowder rau hauv ib qho kev taw qhia ruaj khov. Qhov siab dua qhov taw qhia, qhov ntau dua qhov seem sib nqus flux ntom ntom (qhov ntsuas ntawm lub zog sib nqus).

Thaum cov txheej txheem no tau ua tiav, cov hmoov zoo yog thawj zaug ntim rau hauv pwm, muaj zog hlau nplaum yog siv rau kev taw qhia cov hmoov zoo, thiab tom qab ntawd cov txheej txheem molding yog nqa tawm. Lub cim tshwj xeeb ntawm qhov no yog tias nws maj mam nias-pwm kom zoo li lub cev molded tsis tawg. Vim tias yog tias lub siab loj dhau lawm, nws yuav cuam tshuam qhov kev taw qhia ntawm micropowder uas thaum kawg sib sau ua ke.

Txhawm rau kom ua tiav qhov kev taw qhia siab, nws tseem ceeb heev los tsim qhov chaw nrog ib qho chaw sib nqus hauv cov pwm. Vim lub configuration ntawm lub electromagnet thiab qhov luaj li cas, cov duab thiab cov khoom ntawm cov pwm, lub magnetic teb yuav tsis sib xws, ua rau tsis zoo orientation. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau siv cov kev ntsuam xyuas magnetic teb thiab lwm txoj hauv kev los kho kom zoo kom cov hlau nplaum tsis sib xws.
