Dab tsi yog cov khoom siv hlau nplaum feem ntau siv hauv ruaj khov hlau nplaum motors?

Cov khoom siv hlau nplaum tas mus li feem ntau siv hauv lub cev muaj xws li sintered hlau nplaum thiab cov hlau nplaum sib txuas, cov hom tseem ceeb yog aluminium-nickel-cobalt, ferrite, samarium cobalt, NdFeB thiab lwm yam.

Alnico: Alnico cov khoom siv hlau nplaum ruaj khov yog qhov ntxov tshaj plaws thiab dav siv cov khoom siv hlau nplaum ruaj khov, thiab nws cov txheej txheem kev npaj thiab cov cuab yeej siv tau zoo heev.Tam sim no, muaj cov chaw tsim khoom hauv Nyiv, Tebchaws Meskas, Tebchaws Europe, Russia thiab Tuam Tshoj. cov tuam txhab tsim khoom, cov khoom tsim tawm ntawm Hangzhou cov hlau nplaum ruaj khov tam sim no yog thawj zaug hauv Suav teb, muaj peev xwm txhua xyoo ntawm 3000 tons.
Cov khoom siv hlau nplaum ruaj khov ferrite: nkag mus rau 50′s, ferrite pib vam meej, tshwj xeeb tshaj yog nyob rau hauv 70′s, nyob rau hauv coercivity, magnetic zog tshuab kev ua tau zoo dua strontium-ferrite rau hauv ntau lawm, nthuav dav siv cov hlau nplaum ruaj khov ferrite. Cov khoom siv hlau nplaum uas tsis yog xim hlau, ferrite tsis yooj yim rau oxidize raws li cov khoom siv hlau nplaum ruaj khov, Curie kub thiab cov nqi siab, yog li nws nrov heev.
Samarium cobalt khoom: qhov nce ntawm lub xyoo pua 20th nyob rau hauv nruab nrab-1960s, zoo heev sib nqus hlau nplaum cov ntaub ntawv, thiab ruaj khov heev.Samarium cobalt yog tshwj xeeb tshaj yog haum rau kev tsim hluav taws xob motors los ntawm nam ntawm magnetic zog, tab sis vim nws siab. tus nqi, nws yog tsuas yog siv nyob rau hauv kev tshawb fawb thiab kev loj hlob ntawm aviation, aerospace, riam phom thiab lwm yam tub rog hluav taws xob motors thiab kev ua tau zoo thiab tus nqi tsis yog lub ntsiab tseem ceeb nyob rau hauv high-tech teb ntawm hluav taws xob motors.
NdFeB cov khoom siv: NdFeB cov khoom siv hlau nplaum yog neodymium, hlau oxide thiab lwm yam hlau, tseem hu ua hlau nplaum hlau.Nrog cov khoom siv hluav taws xob tsis tshua muaj zog thiab qhov zoo ntawm lub zog siab ntom ntom, NdFeB cov khoom siv hlau nplaum ruaj khov tau siv dav hauv kev lag luam niaj hnub thiab tshuab hluav taws xob, thiaj li ua cov twj paj nruag, electroacoustic motors, sib nqus sib nqus thiab cov khoom siv magnetization miniaturization, lub teeb yuag, nyias ua tau.Nws yog nquag xeb vim nws cov ntsiab lus siab ntawm neodymium thiab hlau.Surface tshuaj passivation yog ib qho kev daws teeb meem zoo tshaj plaws.
JIUYUAN muaj pab pawg R & D nrog ntau tshaj 20 xyoo kev paub txog me brushless dc lub cev muaj zog,sab nrauv rotor brushless dc lub cev muaj zog,puab rotor brushless dc lub cev muaj zog, brushless dc lub cev muaj zog nrog xws li lossis tsav thiab lwm yam ..Tiv tauj pebrau cov lus qhia ntxaws.
