| Cherechedza: · Pasi pekushanda tembiricha 20 ℃ ± 2 ℃, pamusoro pemagineti paramita uye zvimiro zvemuviri zvinoedzwa, nekurasikirwa kusingadzivisike kwesimba remagineti isingapfuure 5%.· Iyo yakanyanya tembiricha yekushanda yemagineti inoshanduka nekuda kwereshi yehurefu uye dhayamita uye zvakatipoteredza zvinhu. . | ||||||||
Advantage:
Izvo zvimiro zvemagineti aya akanyanya kukwirira kune echinyakare uye parizvino ndiwo ane simba zvakanyanya mukushandisa. Kukwirira kwavo
coercivity uye yakakwirira remanence inobvumira dhizaini nyowani uye mukana wekuwedzera magineti yekushandiswa uko nzvimbo inogumira
kana kuti panodiwa simba remagineti.
NdFeB magineti anonyanya kukanganiswa nekuora. Saka zvinoda kudzivirira pamusoro pekuvhara. Kushandiswa kweNdFeB magineti kwakaiswa
netembiricha munzvimbo yakakura inomhanya kubva pa80ºC kusvika 230ºC. Uye zvakare inoshanda pane tembiricha iri pasi pe0 ℃.
Application:
Neodymium magineti anoshandiswa semhando dzakasiyana dzemagineti lenses yekutarisisa, kutsauka kwezvimedu zvinochaja mumagetsi, mabhureki masisitimu,
kudonha, sensor, magineti system mune rotor uye micro motors, uye munda wesainzi, mushonga (tomography, NMR spectrometers), nezvimwe.
Nhasi, magineti eNdFeB anoshandiswa muhuwandu hwakakura pasi rese. Kugadziriswa kwechinyorwa ichi hakusati kwapera; the remanence
uye simba remumunda rinomanikidza riri kuramba richiwedzerwa. Iyo yakakwira simba reNdFeB magineti zvinoreva kuti mota uye masensa anogona kuvakwa
nguva dzose idiki - uye izvi zvinoratidza kuwedzera kwekuita basa. Kuvandudzwa kuri kuitika kunoita kuti zvinhu izvi zvinonakidza zvirambe zvichi-
yakaunzwa munzvimbo itsva.
Ese maitiro akataurwa akatemerwa uchishandisa akajairwa masampuli zvinoenderana neIEC 60404-5. Izvo zvinotevera zvinotsanangurwa zvinoshanda sereferensi tsika uye
zvinogona kusiyana. Kuti uwane rumwe ruzivo ndapota taura neinjiniya yedu yekushandisa.
