Ngokusho kweBusinessKorea, iHyundai Motor Group isiqalile ukwenza izinjini zezimoto zikagesi ezingathembele kakhulu eChina “izakhi zomhlaba ezingavamile“.
Ngokusho kwabangaphakathi embonini ngo-Agasti 13, i-Hyundai Motor Group okwamanje yenza injini yokushayela engasebenzisi izinto ezingavamile zomhlaba njengei-neodymium, i-dysprosium, futhii-terbiumeNanyang Research Center eHuacheng, Gyeonggi do. Umuntu ongaphakathi embonini uthe, “Iqembu lezimoto iHyundai Motor Group lenza i-'wound rotor synchronous motor (WRSM)' egwema ngokuphelele ukusetshenziswa kozibuthe abangapheli abaqukethe.izakhi zomhlaba ezingavamile
I-Neodymium yinto enozibuthe oqinile. Uma ixutshwe nenani elincane le-dysprosium ne-terbium, ingagcina uzibuthe ngisho nasezingeni lokushisa elifinyelela ku-200 degrees Celsius. Embonini yezimoto, abakhiqizi bezimoto basebenzisa lezi zidonsa ezihlala njalo ezisekelwe ku-neodymium kumamotho abo okushayela, okuvame ukubizwa ngokuthi "inhliziyo yezimoto zikagesi". Kulesi silungiselelo, omagnethi abangunaphakade base-neodymium babekwa ku-rotor (ingxenye ezungezayo yenjini), kuyilapho amakhoyili enziwe ngokujikajika abekwe eduze kwerotha ukushayela injini kusetshenziswa ukumiswa kwe-“Permanent Magnet Synchronous Motor (PMSM)”.
Ngakolunye uhlangothi, injini entsha ethuthukiswa yi-Hyundai Motor Group isebenzisa ama-electromagnets esikhundleni sikazibuthe ongapheli ku-rotor. Lokhu kuyenza injini enganciki ezintweni zomhlaba ezingavamile njenge-neodymium, i-dysprosium, ne-terbium.
Isizathu sokuthi kungani iHyundai Motor Group ishintshele ekuthuthukiseni izinjini zezimoto zikagesi ezingenazo izinto ezingavamile emhlabeni kungenxa yokwanda okukhulu kwamuva nje kokungeniswa komhlaba okungavamile eChina. I-China yenza u-58% wezimayini ze-neodymium emhlabeni kanye nama-90% e-neodymium ecolisisiwe yomhlaba. Ngokusho kweKorea Trade Association, ngokwanda kokukhiqizwa kwezimoto zikagesi ngabakhi bezimoto baseKorea basekhaya, inani lokungenisa izibuthe ezihlala unomphela ikakhulukazi ezakhiwe yizinto ezingavamile zomhlaba lenyuke lisuka ezigidini ezingama-239 zamadola aseMelika (cishe izigidi eziyizinkulungwane ezingama-318 zawina amaKorea) ngo-2020 laya ku-641. izigidi zamadola aseMelika ngo-2022, okuwukunyuka cishe izikhathi ezi-2.7. Cishe ama-87.9% omazibuthe bangempela abangenisiwe abavela eSouth Korea bavela eChina.
Ngokombiko, uhulumeni waseShayina ucabanga ukusebenzisa "ukuvalwa kokuthekelisa kukazibuthe womhlaba okungajwayelekile" njengezinyathelo zokulwa nemikhawulo yokuthumela ngaphandle kwe-semiconductor yase-US. Uma i-China isebenzisa imikhawulo yokuthumela ngaphandle, izothinta ngokuqondile bonke abakhiqizi bezimoto abakhuthaza ngenkuthalo ukuguqulwa okusabalele kwezimoto zikagesi.
Kulesi simo, i-BMW ne-Tesla bafuna ukuthuthukisa izinjini ezingaqukethe izinto ezingavamile zomhlaba. AbakwaBMW sebamukele ubuchwepheshe beWRSM obuthuthukiswa yiHyundai Motor Group ngemoto kagesi iBMW i4. Kodwa-ke, uma kuqhathaniswa nezinjini ezisebenzisa izibuthe zomhlaba ezingavamile, amamotho akhona e-WRSM anokuphila okufushane kanye nokulahlekelwa kwamandla aphezulu noma ithusi, okuholela ekusebenzeni kahle okuphansi. Ukuthi iHyundai Motor Group iyixazulula kanjani le nkinga ingaba yisici esibalulekile ekuzuzeni ubuchwepheshe bezimoto obungenawo umhlaba obungavamile.
Njengamanje uTesla uthuthukisa injini esebenzisa izibuthe ezihlala njalo ze-ferrite, enziwa ngokuxuba izakhi zensimbi ne-iron oxide. Ozibuthe be-Ferrite abangapheli bathathwa njengabangena esikhundleni sikamazibuthe asekelwe ku-neodymium. Kodwa-ke, i-magnetism yabo ibuthakathaka futhi ayifanele ukusetshenziswa ezimotweni zezimoto zikagesi, okuye kwaholela ekugxekeni okuthile embonini.
