Sintered NdFeB Magnet yog 3^rdtiam ntawm cov hlau nplaum ruaj khov tsim nyob rau xyoo 1980. Nws muaj lub zog sib nqus zoo tshaj plaws niaj hnub no. Nrog nws cov yam ntxwv zoo sib nqus, cov hlau nplaum neodymium muaj qhov hloov tau yooj yim rau cov qauv tsim tshiab lossis hloov cov ntaub ntawv qub xws li AlNiCo thiab Ceramic hauv ntau daim ntawv thov, suav nrog kev ua haujlwm siab, brushless DC motors, sib nqus sib nqus, sib nqus resonance duab, sensors thiab hais lus nrov thiab lwm yam.

Neodymium cylinder hlau nplaum tseem hu ua neodymium rod hlau nplaum. Lawv muaj qhov sib luag ncaj nraim thiab ib qho kev hla hla, thiab ntsuas raws li Txoj kab uas hla (D) x Length (L). Cov hlau nplaum Neodymium (Neo lossis NdFeB) yog cov hlau nplaum ruaj khov, thiab ib feem ntawm tsev neeg hlau nplaum uas tsis tshua muaj ntiaj teb. Neodymium lub tog raj kheej hlau nplaum muaj cov khoom sib nqus siab tshaj plaws thiab yog cov khoom lag luam muaj zog tshaj plaws niaj hnub no. Vim lawv lub zog sib nqus, neodymium lub tog raj kheej hlau nplaum yog qhov kev xaiv zoo rau ntau tus neeg siv khoom, kev lag luam thiab kev siv.

Qhov siab dua L / D piv ua rau lub axially magnetized Neodymium lub tog raj kheej hlau nplaum muaj tus nqi gauss ntau dua thiab ua rau nws zoo tsim nyog rau kev ua kom lub tsev sensor thiab reed hloov. Tsis tas li ntawd, Neodymium lub tog raj kheej hlau nplaum nrog ntau dua L / D piv kuj tseem tuaj yeem tsim kom muaj zog rub lub zog ntau dua los ntawm qhov chaw me me sib nqus ncej thiab ua kom pom kev ruaj ntseg zoo dua. Lwm daim ntawv thov sawv cev ntawm Neodymium lub tog raj kheej hlau nplaum suav nrog cov hlau nplaum sib nqus sib cais khib thiab qee daim ntawv thov tuav.

Kev tsim cov txheej txheem ntawm Neodymium Magnets

Cov txheej txheem hmoov metallurgy yog siv los ua cov hlau nplaum sintered Nd-Fe-B.
