Ziziphi izinto zemagnethi ezisetyenziswa rhoqo iinjini zemagnethi ezisisigxina?

Izixhobo zemagnethi ezisisigxina ezisetyenziswa rhoqo kwimoto ziquka imagnethi edibeneyo kunye nemagnethi yokudibanisa, ezona ntlobo ziphambili ziyi-aluminium-nickel-cobalt, i-ferrite, i-samarium cobalt, i-NdFeB njalo njalo.

I-Alnico: Izinto zemagnethi ezisisigxina ze-Alnico zezona zinto zakuqala kwaye zisetyenziswa ngokubanzi kwimagnethi esisigxina, kwaye inkqubo yayo yokulungiselela kunye netekhnoloji ikhulile ngoku, kukho iifektri eJapan, eUnited States, eYurophu, eRussia naseTshayina. amashishini okuvelisa, imveliso yemagnethi esisigxina ye-Hangzhou okwangoku yeyokuqala e-China, enomthamo wonyaka weetoni ezingama-3000.
Izinto ezisisigxina umazibuthe ferrite: wangena 50′s, ferrite waqala ukuchuma, ingakumbi 70′s, ekunyanzelweni, ukusebenza umatshini wamandla kazibuthe ngcono strontium-ferrite kwimveliso ngamanani amakhulu, ngokukhawuleza yandisa ukusetyenziswa ferrite umazibuthe esisigxina.As i-nonmetallic magnetic material, i-ferrite ayilula ukuyikhupha njengentsimbi yemagnethi esisigxina, ubushushu obuphantsi beCurie kunye neendleko eziphezulu, ngoko ithandwa kakhulu.
Izinto eziphathekayo zeSamarium cobalt: ukunyuka kwenkulungwane yama-20 phakathi kwiminyaka yee-1960, izixhobo ezigqwesileyo zemagnethi ezisisigxina, kunye nokusebenza okuzinzile.I-cobalt ye-Samarium ilungele ngokukodwa ukuveliswa kweenjini zombane ukusuka kwinkalo yezakhiwo zemagnethi, kodwa ngenxa yokuphakama kwayo. ixabiso, isetyenziswa ikakhulu kuphando kunye nophuhliso lwe-aviation, i-aerospace, izixhobo kunye nezinye iimoto zombane zomkhosi kunye nokusebenza okuphezulu kunye nexabiso asiyiyo eyona nto iphambili kwintsimi yobuchwepheshe obuphezulu beenjini zombane.
Izinto ze-NdFeB: Izinto zemagneti ze-NdFeB yi-neodymium, i-iron oxide kunye nezinye i-alloy, ekwaziwa ngokuba yintsimbi yemagnethi. ukuze kwenziwe izixhobo, ii-electroacoustic motors, ukwahlukana kwamagnetic kunye ne-magnetization device miniaturization, i-lightweight, thin become possible.Iyakwazi ukugqwala ngenxa yomxholo wayo ophezulu we-neodymium kunye ne-iron.I-Surface chemical passivation yenye yezona zisombululo ezilungileyo.
I-JIUYUAN ineqela le-R&D elinamava angaphezu kwama-20 eminyaka encinci brushless dc motor,i-rotor yangaphandle brushless dc motor,i-rotor yangaphakathi brushless dc motor,i-brushless dc motor enomlawuli okanye ukuqhuba njl.Qhagamshelana nathingolwazi lweenkcukacha.
