NIB magineti anouya mumagiredhi akasiyana, ayo anoenderana nesimba remagineti awo, kubva kuN35 (yakaneta uye isingadhure) kusvika kuN52 (yakasimba, inodhura zvakanyanya uye yakanyanya brittle). Iyo N52 magineti inenge 50% yakasimba kudarika N35 magineti (52/35 = 1.49). MuUS, zvakajairika kuwana vatengi giredhi magineti muN40 kusvika N42 renji. Mukugadzirwa kwevhoriyamu, N35 inowanzoshandiswa kana saizi uye uremu zvisiri zvekufunga zvakanyanya sezvo zvisingadhure. Kana saizi uye uremu zviri zvinhu zvakakosha, mamakisi epamusoro anowanzo shandiswa. Pane premium pamutengo wegiredhi repamusoro magineti saka zvakajairika kuona N48 neN50 magineti anoshandiswa mukugadzira maringe neN52.

Neodymium magineti kana anonyanya kuzivikanwa seNIB, NefeB kana magineti makuru ndiwo ane simba uye anonyanya kushandiswa magineti ekutengesa anowanikwa pasi rese. Nekuumbwa kwemakemikari eNd2Fe14B, neo magineti ane tetragonal crystalline chimiro uye anonyanya kuumbwa nezvinhu zve neodymium, Iron uye Boron. Kwemakore, neodymium magineti yakabudirira kutsiva mamwe marudzi ese echigarire magineti ekushandisa kwakapararira mumamotor, zvemagetsi uye zvimwe zvakasiyana zvemazuva ese zvehupenyu. Nekuda kwekusiyana kwezvinodiwa zvemagineti uye kudhonza simba rebasa rega rega, neodymium magineti anowanikwa nyore mumagiredhi akasiyana. NIB magineti akaiswa mugiredhi zvinoenderana nechinhu chavanogadzirwa nacho. Semutemo wekutanga, kukwirisa mamakisi, kusimba kunoita magineti.
Neodymium nomenclature nguva dzose inotanga ne 'N' ichiteverwa nenhamba yemanhamba maviri mukati memutsara we 24 kusvika 52. Vara 'N' mumagiredhi emagineti emagetsi anomirira neodymium nepo nhamba dzinotevera dzichimiririra huwandu hwesimba rechigadzirwa cheiyo chaiyo. magineti inoyerwa mu 'Mega Gauss Oersteds (MGOe). Mgoe ndiyo yekutanga chiratidzo chekusimba kwechero neo magineti pamwe nehupamhi hwemagineti inogadzirwa nayo mukati mechero mudziyo kana application. Kunyangwe iyo yekutanga huwandu hunotanga neN24 zvakadaro, mamakisi epasi haasisiri kugadzirwa. Saizvozvo, nepo iyo yakanyanya kunaka chigadzirwa simba reNIB inofungidzirwa kusvika kuN64 zvakadaro mazinga esimba akakwira haasati aongororwa zvekutengesa uye N52 ndiyo yepamusoro-soro ikozvino neo giredhi inowanikwa nyore nyore kune vatengi.
Chero mavara ekuwedzera anotevera giredhi anoreva tembiricha zviyero zvemagineti, kana pamwe kusavapo kwayo. Iyo yakajairwa tembiricha zviyero ndeye Nil-MH-SH-UH-EH. Aya mavara ekupedzisira anomiririra tembiricha yeCurie yepamusoro iyo magineti inogona kumira nayo isati yarasa magineti zvachose. Kana magineti ikashandiswa kupfuura tembiricha yeCurie, mhedzisiro yacho ingave kurasikirwa kwekubuda, kuderedzwa kwechigadzirwa uye pakupedzisira isingadzoreki demagnetization.
Nekudaro, saizi yemuviri uye chimiro chechero neodymium magineti inoitawo basa rakakosha mukukwanisa kwayo kushanda zvakanaka patembiricha yakakwira. Uyezve, chimwe chinhu chekuyeuka ndechekuti kusimba kwegineti yakanaka inoenzana nenhamba, zvekuti N37 ingori 9% isina simba pane N46. Nzira yakavimbika yekuverenga iyo chaiyo giredhi yeneo magineti ndeyekushandisa hysteresis graph yekuongorora muchina.
AH Magnet ndeye isingawanzo pasi magineti mutengesi ane hunyanzvi mukutsvagisa, kugadzira, kugadzira uye kutumira yakakwira-inoshanda sintered neodymium iron boron magineti, 47 mamakisi eakajairwa neodymium magineti, kubva kuN33 kusvika 35AH, uye GBD Series kubva 48SH kusvika 45AH iripo. Kana iwe uchifarira zvigadzirwa zvedu, tapota taura nesu ikozvino!
