Ngokutsho kweBusinessKorea, iHyundai Motor Group sele iqalile ukuphuhlisa iimoto zemoto zombane ezingathembeli kakhulu eTshayina "izinto zomhlaba ezinqabileyo“.
Ngokutsho kwabangaphakathi kwishishini nge-13 ka-Agasti, iHyundai Motor Group ngoku iphuhlisa injini yokuqhubela phambili engasebenzisi izinto ezinqabileyo zomhlaba ezifana neneodymium, idysprosium, kwayeterbiumkwiziko layo loPhando lweNanyang eHuacheng, Gyeonggi yenza. Umntu ongaphakathi kumzi mveliso uthe, "Iqela leeMoto lakwaHyundai liphuhlisa 'inxeba le-rotor synchronous motor (WRSM)' ekuthintela ngokupheleleyo ukusetyenziswa kweemagnethi ezisisigxina.izinto zomhlaba ezinqabileyo
I-Neodymium yinto enemagnethi eyomeleleyo. Xa ixutywe nezixa zomkhondo we-dysprosium kunye ne-terbium, inokugcina uzibuthe nokuba kumaqondo obushushu ukuya kutsho kuma-200 degrees celcius. Kwimizi-mveliso yeemoto, abavelisi bezithuthi basebenzisa ezi magnethi zisekwe kwi-neodymium ezisisigxina kwiimoto zabo zokuqhubela phambili, ezihlala zibizwa ngokuba "yintliziyo yezithuthi zombane". Kulo cwangciso, i-neodymium esekelwe kwiimagnethi ezisisigxina zifakwe kwi-rotor (inxalenye ejikelezayo yemoto), ngelixa iikhoyili ezenziwe ngokujikeleza zibekwe malunga ne-rotor ukuqhuba i-motor usebenzisa i-"Permanent Magnet Synchronous Motor (PMSM)" uqwalaselo.
Kwelinye icala, injini entsha ephuhliswa yiHyundai Motor Group isebenzisa iimagnethi endaweni yeemagnethi ezisisigxina kwirotor. Oku kuyenza injini engaxhomekekanga kwizinto ezinqabileyo zomhlaba ezifana neodymium, i-dysprosium, kunye ne-terbium.
Isizathu sokuba i-Hyundai Motor Group itshintshele ekuphuhliseni iimoto zemoto zombane ezingaqulathanga izinto ezinqabileyo zomhlaba kungenxa yokwanda okukhulu kwamva nje kokungeniswa komhlaba okunqabileyo kweTshayina. I-China yenza i-58% yemveliso yemigodi ye-neodymium yehlabathi kunye ne-90% ye-neodymium esulungekileyo yehlabathi. Ngokutsho koMbutho wezoRhwebo waseKorea, ngokunyuka kwemveliso yeemoto zombane ngabavelisi baseKorea basekhaya, ixabiso lokungeniswa kweemagnethi ezisisigxina ezihlanganiswe nezinto ezinqabileyo zomhlaba liye lanyuka ukusuka kwi-239 yezigidi zeedola zase-US (malunga ne-318 yezigidigidi zaseKorea) ngo-2020 ukuya kwi-641. izigidi zeedola zaseMelika ngo-2022, ukwanda kwamaxesha aphantse abe ngama-2.7. Malunga ne-87.9% yeemagnethi ezisisigxina ezivela eMzantsi Korea zisuka eTshayina.
Ngokwengxelo, urhulumente wase-China ucinga ukusebenzisa "ukuvalwa kwe-magnetic ukuthumela ngaphandle komhlaba" njengenyathelo lokuchasana nezithintelo zokuthumela ngaphandle kwe-semiconductor yase-US. Ukuba i-China iphumeza izithintelo zokuthumela ngaphandle, iya kubetha ngokuthe ngqo kubo bonke abavelisi bezithuthi abakhuthaza ngenkuthalo ukuguqulwa okubanzi kwezithuthi zombane.
Kule meko, iBMW kunye neTesla zikwafuna ukuphuhlisa iimotor ezingaqulathanga izinto ezinqabileyo zomhlaba. I-BMW yamkele iteknoloji ye-WRSM ephuhliswa yi-Hyundai Motor Group kwi-BMW i4 imoto yombane. Nangona kunjalo, xa kuthelekiswa neenjini ezisebenzisa iimagnethi zomhlaba ezinqabileyo, iimotor zeWRSM ezikhoyo zinobomi obufutshane kunye namandla aphezulu okanye ilahleko yobhedu, okukhokelela ekusebenzeni okuphantsi. Indlela iHyundai Motor Group iyisombulula ngayo le ngxaki inokuba yeyona nto iphambili ekuphumezeni ubuchwephesha bezithuthi obunqabileyo emhlabeni.
I-Tesla okwangoku iphuhlisa i-motor isebenzisa iimagnethi ezisisigxina ze-ferrite, ezenziwe ngokuxuba izinto zetsimbi kunye ne-iron oxide. Iimagnethi ezisisigxina zeFerrite zithathwa njengeendawo ezithatha indawo yemagnethi esisigxina eneodymium. Nangona kunjalo, i-magnetism yabo ibuthathaka kwaye ayifanelekanga ukusetyenziswa kwiimoto zemoto zombane, ezikhokelele ekugxekeni okuthile kwishishini.
