Sekureva kweBusinessKorea, Hyundai Motor Group yatanga kugadzira mota dzemagetsi dzisinganyanyovimba neChinese "zvisingawanzo zvinhu zvepasi“.
Sekureva kwevanopinda mukati meindasitiri muna Nyamavhuvhu 13, Hyundai Motor Group parizvino iri kugadzira mota yekufambisa isingashandisi zvinhu zvisingawanzo pasi senge.neodymium, dysprosium,uyeterbiumpaNanyang Research Center muHuacheng, Gyeonggi ita. Mumwe muindasitiri anoti, "Hyundai Motor Group iri kugadzira 'ronda rotor synchronous mota (WRSM)' iyo inodzivirira zvachose kushandiswa kwemagineti echigarire ane.zvisingawanzo zvinhu zvepasi
Neodymium chinhu chine simba remagineti. Kana yakasanganiswa nehuwandu hwe dysprosium uye terbium, inogona kuchengetedza magineti kunyangwe patembiricha inosvika 200 degrees Celsius. Muindasitiri yemotokari, vagadziri vemotokari vanoshandisa aya neodymium akavakirwa magineti echigarire mumamota avo ekufambisa, anowanzo kunzi "moyo wemotokari dzemagetsi". Muchigadziro ichi, neodymium yakavakirwa magineti echigarire anoiswa mu rotor (chikamu chinotenderera chemota), nepo macoil anogadzirwa nemhepo anoiswa akatenderedza rotor kutyaira mota uchishandisa “Permanent Magnet Synchronous Motor (PMSM)” kumisikidzwa.
Kune rimwe divi, mota nyowani iri kugadzirwa neHyundai Motor Group inoshandisa magineti emagetsi panzvimbo pemagineti echigarire mu rotor. Izvi zvinoita kuti ive mota isingavimbe nezvinhu zvisingawanzo pasi senge neodymium, dysprosium, uye terbium.
Chikonzero nei Hyundai Motor Group ichichinjira mukugadzira mota dzemagetsi dzisina zvinhu zvisingawanzo pasi imhaka yekuwedzera kwakakosha kwezvinotengeswa kunze kwenyika kuChina. China inotora 58% yemugodhi wepasi rose we neodymium uye 90% yepasi rose yakacheneswa neodymium. Sekureva kweKorea Trade Association, nekuwedzera kwekugadzirwa kwemotokari dzemagetsi nevanogadzira mota vekuKorea, kukosha kwekupinza kwemagineti echigarire anonyanya kuumbwa nezvinhu zvisingaite zvepasi kwakawedzera kubva pamadhora mazana maviri nemakumi matatu nepfumbamwe emadhora (anenge mabhiriyoni mazana matatu nemakumi mapfumbamwe nemasere akahwina) muna 2020 kusvika mazana matanhatu nemakumi mana nenomwe. miriyoni yemadhora ekuAmerica muna 2022, kuwedzera kweanenge 2.7 nguva. Inosvika 87.9% yemagineti anotengeswa kunze kwenyika kubva kuSouth Korea anobva kuChina.
Sekureva kwemushumo, hurumende yeChina iri kufunga kushandisa "rare pasi magineti kurambidzwa kunze kwenyika" senzira yekupokana neUS semiconductor kurambidzwa kunze kwenyika. Kana China ikaita zvirambidzo kunze kwenyika, icharova vagadziri vese vemotokari vanoshingairira kusimudzira shanduko yakapararira yemotokari dzemagetsi.
Mumamiriro ezvinhu aya, BMW neTesla vari kutsvagawo kugadzira mota dzisina kujairika zvinhu zvepasi. BMW yatora tekinoroji yeWRSM iri kuvandudzwa neHyundai Motor Group muBMW i4 yemagetsi mota. Nekudaro, zvichienzaniswa nemamotor anoshandisa isingawanzo pasi magineti, aripo WRSM mota ane hupenyu hupfupi uye yakakwirira simba kana kurasikirwa kwemhangura, zvichikonzera kuderera kwekuita. Maitiro eHyundai Motor Group anogadzirisa dambudziko iri anogona kunge ari chinhu chakakosha mukuwana isingawanzo pasi yemahara mota tekinoroji.
Tesla parizvino iri kugadzira mota ichishandisa ferrite magineti echigarire, ayo anogadzirwa nekusanganisa zvinhu zvesimbi nesimbi oxide. Ferrite magineti echigarire anoonekwa seanotsiva neodymium akavakirwa magineti echigarire. Nekudaro, magineti avo haana kusimba uye haana kukodzera kushandiswa mumagetsi emotokari mota, izvo zvakakonzera kumwe kushoropodzwa muindasitiri iyi.
