Anisotropic Sintered NdFeB NIB Ring Magnet Dindindin

Sintered NIB Magnets
Sintered NIB maganadiso suna da mafi girma ƙarfi amma an iyakance ga in mun gwada da sauki geometries kuma zai iya zama gaggautsa. Ana yin su ne ta hanyar matsi da ke samar da albarkatun ƙasa zuwa tubalan, wanda sannan ya bi ta hanyar dumama mai rikitarwa. Daga nan sai a yanke katangar don siffa kuma a rufe shi don hana lalata. Sintered maganadiso yawanci anisotropic ne, wanda ke nufin suna da fifiko ga alkiblar filin maganadisu. Magnetization maganadisu da "hatsi" zai rage ƙarfin maganadisu da har zuwa 50% na kasuwanci samuwa maganadiso ko da yaushe magnetized a cikin fi so shugabanci na Magnetization.

Demagnetization
NIB maganadiso da gaske ne na dindindin maganadiso, kamar yadda suka rasa a cikin maganadisu, ko degauss ta halitta, a kusan 1% a cikin karni. Gaba ɗaya suna aiki a cikin kewayon zafin jiki na-215°Fto 176°F(-138°C zuwa 80°℃). Don aikace-aikacen da ke buƙatar kewayon zafin jiki mai faɗi, Samarium Cobalt (SmCo) maganadiso ana amfani da su.

Rufi
Saboda NIB wanda ba a rufe shi ba zai lalace kuma ya ruguje tare da fallasa yanayin, ana sayar da su tare da murfin kariya. Mafi yawan abin rufe fuska an yi shi da nickel, kodayake sauran kayan kwalliyar da ake samu na kasuwanci suna ba da juriya ga yanayin zafi mai zafi, zafi mai zafi, fesa gishiri, kaushi da gas.

Daraja
NIB maganadiso ya zo da maki daban-daban, wanda yayi daidai da ƙarfin ƙarfin maganadisu, kama daga N35 (mafi rauni kuma mafi ƙarancin tsada) zuwa N52 (mafi ƙarfi, mafi tsada kuma mafi gaggautsa). 52/35 = 1.49). A cikin Mu, abu ne na yau da kullun don nemo madaidaicin mabukaci a cikin kewayon N40 zuwa N42. A cikin samar da girma, ana amfani da N35 sau da yawa idan girman kuma nauyi ba babban abin la'akari bane saboda yana da ƙarancin tsada. f girma da nauyi abubuwa ne masu mahimmanci, yawanci ana amfani da manyan maki. Akwai farashi akan farashin maɗaukaki masu daraja don haka an fi ganin N48 da N50 magnets da ake amfani da su wajen samarwa akan N52.
