Ikomeye cyane N52 Neodymium Magnet Uruziga Ø50 x20mm

Honsen Magneticsagurisha magnesi yemewe ya neodymium.Magneti ya neodymium (izwi kandi nka NdFeB NIB cyangwa Neo magnet) ubwoko bukoreshwa cyane bwa magneti adasanzwe-yisi, ni rukuruzi ihoraho ikozwe mu ruvange rwa neodymium, fer na boron kugirango ibe imiterere ya tetragonal ya Nd2Fe14B.Yakozwe mu 1982 na General Motors na Sumitomo Metals idasanzwe, magnesi ya neodymium nubwoko bukomeye bwa rukuruzi ihoraho iboneka mubucuruzi.Basimbuye ubundi bwoko bwa magneti mubisabwa byinshi mubicuruzwa bigezweho bisaba magneti akomeye ahoraho, nka moteri mubikoresho bidafite umugozi, disiki zikomeye hamwe na magnetiki.Ntabwo uzi neza niba Neodymium aribikoresho byiza byo gusaba?kanda hano kugirango ubone ikiranga no kugereranya ibikoresho byose bya magneti dutanga.

Neodymium izenguruka magnet ihoraho Ibisobanuro

Imiterere ya tetragonal Nd2Fe14B ya kristaliste ifite hejuru cyane idasanzwe ya magnetocrystalline anisotropy (HA ~ 7 teslas-magnetique yumurima imbaraga H muri A / m nigihe cya magneti muri A.m2).Ibi biha ibice ubushobozi bwo kugira imbaraga nyinshi (ni ukuvuga kurwanya demagnetised).Urwo ruganda rufite kandi magnetisiyasi yuzuye (Js ~ 1,6 T cyangwa 16 kG) kandi mubisanzwe 1.3 teslas. Kubera iyo mpamvu, kubera ko ingufu nyinshi zingana na js2, iki cyiciro cya magneti gifite ubushobozi bwo kubika imbaraga nyinshi za magneti (BHmax ~ 512 kJ / m3 cyangwa 64 MG · Oe) Uyu mutungo uri hejuru cyane mu mavuta ya NdFeB kuruta muri magneti ya samarium cobalt (SmCo), akaba aribwo bwoko bwa mbere bwa magneti adasanzwe-yisi yagurishijwe.Mubimenyerezo, ibintu bya magnetique ya magneti ya neodymium biterwa nibigize amavuta, microstructure, hamwe nubuhanga bwo gukora bukoreshwa.n45 disiki ya magnetiki
