Round Ring Block Arc Permanent Ferrite Magnet
Ingcaciso yeMveliso
Imagnethi yeFerrite (ekwabizwa ngokuba yimagnethi yeceramic) yimagnethi esisigxina.
Ikakhulu ziyi-Strontium esekelwe (i-SrFe2O3), eyenziwe kunye ne-Strontium Carbonate additive ukunyusa ukusebenza kwi-Barium ephelelwe lixesha (BaFe2O3).
Amandla abo alungileyo okunyanzela avela kwikristale ephezulu ye-anisotropy ye-strontium iron oxide. Nangona kunjalo, iindawo ze-isotropic zinokuveliswa apho kufuneka i-multi-pole magnetization elula kwaye kulula.
Ngokubhekiselele kwiimpawu zombane, ukuxhathisa kwe-ferrite kukhulu kakhulu kuneyentsimbi kunye ne-alloy materials magnetic, kwaye ineempawu eziphezulu ze-dielectric.
Iipropathi zemagneti zeferrite zikwabonisa ukufikeleleka okuphezulu kumaza aphezulu.
I-Ferrite ayiqhubeki kwaye inokumelana okuphezulu ngokuchasene nokubola, iiasidi, iityuwa, kunye nezinto zokuthambisa. Iimilo eziqhelekileyo zilula, njengediski, iibhloko, iisilinda, imisesane, kunye neearcs.
Iimagnethi zeFerrite ziqhele ukusetyenziswa kwizicelo ezahlukeneyo kumashumi eminyaka adlulileyo, njengezandisi-lizwi, iimotor, kunye neejenereyitha.
