Sintered NdFeB Magnet

Lus piav qhia luv luv:

Neodymium hlau nplaum (NdFeB) - tsis tshua muaj lub ntiaj teb cov hlau nplaum ruaj khov tsim los ntawm neodymium, hlau thiab boron, Tuam Tshoj tau pib ua cov mining hauv tsev hauv xyoo 1980s. NeFeB hlau nplaum yog compressed thiab sintered nyob rau hauv ib tug tiv thaiv cua. Yog tias cov txheej txheem tsis raug tswj tau zoo, nws yuav ua rau muaj qhov tsis zoo vim corrosion. Thaum SURTIME, peb tshem tawm cov teeb meem no txij thaum pib los ntawm kev nqa cov kev tswj xyuas zoo thiab peb suav tias yog qhov tseem ceeb, tsis yog ntawm cov khoom kawg nkaus xwb tab sis kuj tseem muaj cov txheej txheem tseem ceeb ntawm qhov chaw.

Nco tseg: · Nyob rau hauv kev ua hauj lwm kub 20 ℃ ± 2 ℃, saum toj no magnetic tsis thiab lub cev muaj zog yog kuaj, nrog inevitable poob ntawm magnetic quab yuam tsis ntau tshaj 5%. .

Qhov zoo:
Cov khoom ntawm cov hlau nplaum no yog qhov zoo tshaj rau cov tsoos ib txwm muaj thiab tam sim no lawv muaj zog tshaj plaws hauv daim ntawv thov. Lawv siab

coercivity thiab siab remanence tso cai rau tus tshiab tsim thiab muaj peev xwm nce magnetic teb ntawm daim ntawv thov qhov twg qhov chaw yog txwv

los yog qhov chaw muaj zog magnetic teb xav tau.

NdFeB hlau nplaum yog qhov muaj zog heev rau corrosion. Yog li ntawd yuav tsum tau ib tug tiv thaiv nto txheej. Kev siv NdFeB hlau nplaum yog conditioned

los ntawm qhov kub thiab txias nyob rau hauv ntau yam khiav ntawm 80ºC mus rau 230ºC. Thiab tseem nws ua haujlwm ntawm qhov kub hauv qab 0 ℃.

Daim ntawv thov:
Neodymium hlau nplaum yog siv los ua ntau hom sib nqus lo ntsiab muag rau kev tsom, deflection ntawm cov khoom siv hluav taws xob hauv hluav taws xob, nres tshuab,

drip, sensor, sib nqus system hauv rotor thiab micro motors, thiab kev tshawb fawb, tshuaj (tomography, NMR spectrometers), thiab lwm yam.

Niaj hnub no, NdFeB hlau nplaum tau siv ntau ntau thoob plaws ntiaj teb. Txoj kev loj hlob ntawm cov khoom no tseem tsis tau tiav; lub remanence

thiab coercive field lub zog tau nce ntxiv. Lub zog siab ntawm NdFeB hlau nplaum txhais tau tias cov motors thiab sensors tuaj yeem tsim tau

puas me dua - thiab qhov no qhia txog kev nce hauv kev ua tau zoo. Cov kev txhim kho tsis tu ncua ua rau cov ntaub ntawv nthuav dav no tuaj yeem cuam tshuam.

nually nkag rau hauv thaj chaw tshiab.

Txhua tus nqi teev tseg tau txiav txim siab siv cov qauv qauv raws li IEC 60404-5. Cov nram qab no specifications ua raws li cov nqi siv thiab

tej zaum yuav txawv. Yog xav paub ntxiv thov hu rau peb daim ntawv thov engineers.
