Sida laga soo xigtay BusinessKorea, Hyundai Motor Group ayaa bilaabay horumarinta matoorada baabuurta korontada ku shaqeeya ee aan si weyn ugu tiirsanayn Shiinaha "curiyayaasha dhulka naadir“.
Sida laga soo xigtay khubaro dhanka warshadaha ah Agoosto 13-keedii, Kooxda Hyundai Motor Group waxay hadda horumarinaysaa matoor aan isticmaalin curiyayaasha dhulka naadir ah sidaneodymium, dysprosiumiyoterbiumXarunteeda Cilmi-baarista ee Nanyang ee Huacheng, Gyeonggi do.Khubaro dhinaca warshadaha ah ayaa yidhi, "Hyundai Motor Group waxa ay soo saaraysaa 'boorka rotor synchronous motor (WRSM)' kaas oo si buuxda uga fogaanaya isticmaalka birlab joogto ah oo ay ku jiraancuriyayaasha dhulka naadir
Neodymium waa walax leh magnetism xooggan.Marka lagu qaso cadadka dysprosium iyo terbium, waxay ilaalin kartaa magnetismka xitaa heerkulka ilaa 200 darajo Celsius.Warshadaha baabuurta, kuwa soo saara baabuurta waxay isticmaalaan magnets-ka joogtada ah ee neodymium ku salaysan matoorada kicinta, oo inta badan loo yaqaan "wadnaha baabuurta korontada".Goobtan, neodymium magnets joogto ah ayaa la gelinayaa rotor-ka (qaybta wareegta ee matoorka), halka gariiradaha ka samaysan dabaylaha lagu dhejiyo wareegga wareegga si loo kaxeeyo mootada iyadoo la adeegsanayo qaabaynta "Mashiinka Isku-xirka Joogtada ah ee Magnet (PMSM)".
Dhanka kale, matoorka cusub ee ay soo saartay kooxda Hyundai Motor Group waxay isticmaashaa koronto-magnet halkii ay ka isticmaali lahaayeen birlab joogto ah rotor-ka.Tani waxay ka dhigaysaa matoor aan ku tiirsanayn walxaha dhulka dhifka ah sida neodymium, dysprosium, iyo terbium.
Sababta ay shirkadda Hyundai Motor Group u beddeshay horumarinta matoorada baabuurta korontada ku shaqeeya ee aan ku jirin curiyeyaasha dhulka naadirka ah waxaa sabab u ah kororka weyn ee dhowaanahan soo dejinta naadirka ah ee Shiinaha.Shiinaha ayaa 58% ka ah wax soo saarka macdanta neodymium ee adduunka iyo 90% ee neodymium-ka la safeeyey ee adduunka.Sida laga soo xigtay Ururka Ganacsiga Kuuriya, iyada oo korodhka wax soo saarka baabuurta korontada ee baabuurta gudaha ee Kuuriya, qiimaha soo dejinta ee magnets-ka joogtada ah ee inta badan ka kooban walxaha dhifka ah ee dhulka ayaa kor u kacay 239 milyan oo doolarka Maraykanka ah (qiyaastii 318 bilyan oo Kuuriyaan ah) 2020 ilaa 641 milyan doolarka Mareykanka ah sanadka 2022, koror ku dhawaad 2.7 jeer.Qiyaastii 87.9% magnets-ka joogtada ah ee laga keeno Kuuriyada Koonfureed waxay ka yimaadaan Shiinaha.
Sida warbixinta lagu sheegay, dowladda Shiinaha ayaa ka fiirsaneysa inay u isticmaasho "mamnuucidda dhoofinta magnet-ka naadir ah" si looga hortago xannibaadaha dhoofinta semiconductor ee Mareykanka.Haddii Shiinuhu uu fuliyo xayiraadaha dhoofinta, waxay si toos ah u garaaci doontaa dhammaan soosaarayaasha baabuurta kuwaas oo si firfircoon u dhiirrigeliya isbeddelka baahsan ee baabuurta korontada.
Xaaladdan oo kale, BMW iyo Tesla waxay sidoo kale raadinayaan inay horumariyaan matoorada aan ku jirin curiyeyaasha dhulka naadir ah.BMW waxa ay qaadatay tignoolajiyada WRSM ee ay samaysay kooxda Hyundai Motor Group ee gaadhiga korantada ee BMW i4Si kastaba ha ahaatee, marka la barbar dhigo matoorada isticmaalaya magnets dhulka naadir ah, matoorada WRSM ee jira waxay leeyihiin cimri gaaban oo tamar sare ama khasaare naxaas ah, taasoo keenta waxtarka hoose.Sida kooxda Hyundai Motor Group u xalliso dhibaatadan waxa laga yaabaa inay tahay arrin fure u ah helitaanka tignoolajiyada baabuurta bilaashka ah ee dhulka naadir ah.
Tesla waxay hadda horumarinaysaa matoor isticmaalaya magnets joogto ah oo ferrite ah, kuwaas oo lagu sameeyo isku dhafka walxaha birta ah iyo oksaydhka birta.Magnet-ka joogtada ah ee Ferrite waxa loo tixgaliyaa beddelka magnet-ka joogtada ah ee ku salaysan neodymium.Si kastaba ha ahaatee, magnetismkoodu waa daciif oo kuma habboona in loo isticmaalo matoorada baabuurta korontada, taas oo keentay in qaar ka mid ah dhaleeceynta warshadaha.
