Ngokusho kweBorsingkorea, iHyundai Motor Group isiqale ukwakha izimoto zikagesi ezithembela kakhulu kumaShayina "izinto zomhlaba ezingavamile".
Ngokusho kwabashintshi bemboni engaphakathi ku-Agasti 13, iHyundai Motor Group njengamanje ithuthukisa i-motor ye-propulsion engasebenzisi izinto zomhlaba ezingandile ezifananeedymium, dysprosium, futhii-terbiumEsikhungweni sakwa-Namang Research Center sayo eHuacheng, i-Gyeonggi yenza. Umkhakha Insider uthe, "IHyundai Motor Group ithuthukisa i-'Clen Rotor Synchronous motor (WRSM) 'egwema ngokuphelele ukusetshenziswa kwezibuko zaphakade eziquketheizinto zomhlaba ezingavamile
I-Neodymium yinto enamandla kazibuthe oqinile. Lapho kuxutshwa namanani alandelwayo e-dysprosium ne-terbium, kungagcina ubusika ngisho nasemazingeni okushisa afinyelela kuma-degrees angama-200. Embonini yezimoto, abakhiqizi bezimoto basebenzisa lezi ze-neodmimi ze-Neodmimi ezisekelwe unomphela kuma-motor alabo abalandela ama-motors, evame ukubizwa ngokuthi "inhliziyo yezimoto zikagesi". Kulesi silungiselelo, ama-neodymium asuselwa kuzibuko zaphakade abekwa ku-rotor (ingxenye ejikelezayo yemoto), kanti amakhoyili enziwe ngomoya abekwe ezungeze imoto ethi "I-Prefnt Magnet Synchronous Motor (PMSM)".
Ngakolunye uhlangothi, imoto entsha yathuthukiswa yiHyundai Motor Group isebenzisa ama-electromagnets esikhundleni sozibukeli zaphakade ku-rotor. Lokhu kwenza kube yimoto engathembeli ezintweni zomhlaba ezingandile ezifana ne-neodymium, i-dysprosium, ne-terbium.
Isizathu esenza ukuthi iHyundai Motor Group iguqukele ekwakheni ama-motor kagesi angenayo aqukethe izinto zomhlaba ezingandile kungenxa yokwanda okuphawuleka kwakamuva komhlaba okuvamile kwaseChina emhlabeni. I-China i-China i-58% ye-Neordmium Mining akhipha kanye nama-90% we-neodymium acwengekileyo emhlabeni. Ngokusho kwe-Korea Trade Association, ngokwanda kokukhiqizwa kwezimoto zikagesi ngabasebenza ngezimoto zaseKorea zasekhaya, ama-258 billion Korea anqobile (cishe ama-dollar angama-341 angama-641 ama-US e-US ngo-2022, kwanda cishe amahlandla angama-2022. Cishe ama-87,9% ama-overset angenisiwe anaphakade avela eSouth Korea aqhamuka eChina.
Ngokusho kombiko, uhulumeni waseChina ucubungula ukusebenzisa i- "Rare Earth Magnet Exx Exx Export Babst" njengezinto eziphikisayo ngokumelene nemikhawulo yokuthumela ngaphandle yase-Semonductor. Uma i-China isebenzisa imikhawulo yokuthumela kwamanye amazwe, izoshaya ngqo abakhiqizi bezimoto bonke abakhuthaza ngenkuthalo ukuguqulwa kwezimoto ezigcwele zikagesi.
Kulesi simo, iBMW noTesla nabo bafuna ukuthuthukisa ama-motors angenazo izinto zomhlaba ezingavamile. IBMW yamukele ubuchwepheshe be-WRSM abathuthukiswa yiHyundai Motor Group ku-BMW I4 Electric Vehicle. Kodwa-ke, uma kuqhathaniswa nama-motors asebenzisa ama-rap womhlaba akhona, ama-WRSM motors akhona anesifo esifushane sokuphila kanye namandla aphezulu noma ukulahleka kwethusi, okuphumela ekusebenzeni kahle. IHyundai Motor Group ixazulula kanjani le nkinga kungaba yinto ebalulekile ekufezekiseni ubuchwepheshe bezimoto zamahhala.
UTesla njengamanje uthuthukisa imoto esebenzisa ama-Ferrite waphakade, ezenziwa ngokuxuba izinto zensimbi nge-iron oxide. UFerrite uhlale unomphela kubhekwa njengezigatshana zama-neodymium asuselwa kuzibuthe ezingapheli. Kodwa-ke, ubukhosi babo bubuthakathaka futhi bungakulungele ukusetshenziswa kuma-motor kagesi kagesi, okuholele ekugxekeni okuthile embonini.
