Malinga ndi BusinessKorea, Gulu la Hyundai Motor Group layamba kupanga ma mota amagetsi omwe sadalira kwambiri China "zosowa zapadziko lapansi“.
Malinga ndi omwe ali mkati mwamakampani pa Ogasiti 13, Hyundai Motor Group pakadali pano ikupanga injini yoyendetsa yomwe sigwiritsa ntchito zinthu zapadziko lapansi zomwe sizipezeka ngati dziko lapansi.neodymium, dysprosium,nditerbiumku Nanyang Research Center ku Huacheng, Gyeonggi do.Wodziwa zamakampani adati, "Hyundai Motor Group ikupanga 'wound rotor synchronous motor (WRSM)' yomwe imapewa kugwiritsa ntchito maginito osathazosowa zapadziko lapansi
Neodymium ndi chinthu chokhala ndi maginito amphamvu.Ikasakanizidwa ndi kuchuluka kwa dysprosium ndi terbium, imatha kusunga maginito ngakhale kutentha mpaka madigiri 200 Celsius.M'makampani opanga magalimoto, opanga magalimoto amagwiritsa ntchito maginito okhazikika a neodymium m'magalimoto awo, omwe nthawi zambiri amatchedwa "mtima wamagalimoto amagetsi".Pazigawo izi, maginito okhazikika a neodymium amayikidwa mu rotor (gawo lozungulira la mota), pomwe zozungulira zozungulira zimayikidwa mozungulira rotor kuyendetsa galimotoyo pogwiritsa ntchito kasinthidwe ka "Permanent Magnet Synchronous Motor (PMSM)".
Kumbali ina, mota yatsopano yomwe ikupangidwa ndi Hyundai Motor Group imagwiritsa ntchito ma elekitirodi m'malo mwa maginito okhazikika mu rotor.Izi zimapangitsa kuti ikhale injini yomwe sidalira zinthu zapadziko lapansi zomwe sizikupezeka monga neodymium, dysprosium, ndi terbium.
Chifukwa chomwe Hyundai Motor Group yasinthiratu kupanga ma mota amagetsi omwe alibe zinthu zachilendo padziko lapansi ndichifukwa chakuchulukira kwaposachedwa kwa zinthu zomwe zimachokera kunja kwa dziko la China.China ili ndi 58% ya migodi ya neodymium padziko lonse lapansi ndi 90% ya neodymium yoyengedwa padziko lonse lapansi.Malinga ndi Korea Trade Association, pakuwonjezeka kwa kupanga magalimoto amagetsi ndi opanga magalimoto aku Korea, kufunikira kwa maginito okhazikika omwe amapangidwa ndi zinthu zosowa padziko lapansi kwakwera kuchokera pa $ 239 miliyoni (pafupifupi 318 biliyoni yaku Korea) mu 2020 mpaka 641. miliyoni US madola mu 2022, chiwonjezeko pafupifupi 2.7 nthawi.Pafupifupi 87.9% ya maginito okhazikika ochokera ku South Korea amachokera ku China.
Malinga ndi lipotilo, boma la China likuganiza zogwiritsa ntchito "kuletsa kutumizira kunja kwa maginito padziko lapansi" ngati njira yothanirana ndi zoletsa zaku US za semiconductor.Ngati China igwiritsa ntchito zoletsa zotumiza kunja, idzagunda mwachindunji opanga magalimoto onse omwe amalimbikitsa mwachangu kusinthika kwa magalimoto amagetsi.
Pakadali pano, BMW ndi Tesla akufunanso kupanga ma mota omwe alibe zinthu zapadziko lapansi.BMW yatengera ukadaulo wa WRSM womwe ukupangidwa ndi Hyundai Motor Group mugalimoto yamagetsi ya BMW i4.Komabe, poyerekeza ndi ma mota omwe amagwiritsa ntchito maginito osowa padziko lapansi, ma WRSM motors omwe alipo amakhala ndi moyo waufupi komanso kutayika kwamphamvu kapena kutayika kwa mkuwa, zomwe zimapangitsa kuti pakhale kuchepa kwachangu.Momwe Hyundai Motor Group imathetsera vutoli ikhoza kukhala chinthu chofunikira kwambiri pakukwaniritsa ukadaulo wamagalimoto osowa padziko lapansi.
Tesla pakali pano akupanga mota pogwiritsa ntchito maginito okhazikika a ferrite, omwe amapangidwa ndikusakaniza zinthu zachitsulo ndi iron oxide.Maginito okhazikika a Ferrite amawonedwa ngati m'malo mwa maginito okhazikika a neodymium.Komabe, maginito awo ndi ofooka komanso osayenerera kuti agwiritsidwe ntchito pamagetsi amagetsi amagetsi, zomwe zachititsa kuti anthu azitsutsidwa m'makampani.
