Mota Kubudirira Kuwedzeredza uye Kuwedzera Kudiwa kweRare Earth Magnets pasi peDual Carbon Zvinangwa.

Ichitungamirwa nezvinangwa zviviri zvekabhoni, hurumende yakaunza zviyero zvesimba rekushandisa zvakanaka uye nhanho dzekukurudzira kusimudzira kuchengetedza kwesimba uye kuderedzwa kwekubuda muindasitiri yemotokari. Data yazvino inoratidza kuti maindasitiri emotor ane IE3 uye pamusoro pesimba rekushandisa ratings akakurumidza kuwana mukurumbira nekuda kwemaitirwo emitemo, panguva imwe chete ichikurudzira kukura kunoshamisa mune sintered neodymium-iron-boron (NdFeB) magineti.

Muna 2022, kugadzirwa kweIE3 uye pamusoro pemagetsi anoshanda nesimba kwakawedzera ne81.1% gore-pa-gore, nepo iyo yeIE4 uye pamusoro pemotor yakawedzera ne65.1%, nekutengesa kunze kwenyika kwakawedzera ne14.4%. Kukura uku kunokonzerwa nekuitwa kwe "Motor Energy Efficiency Improvement Plan (2021-2023)", iyo ine chinangwa chekuwana kugadzirwa kwepagore kwe170 miriyoni kW yemamotor ekuchengetedza simba zvakanyanya panosvika 2023, inodarika makumi maviri muzana ari-mu-sevhisi mota. Pamusoro pezvo, kuisirwa kweiyo GB 18613-2020 yakajairwa kunomiririra kupinda kwakazara kweindasitiri yemotokari munguva yekushanda kwakanyanya.

Kuwanda kweIE3 uye pamusoro pemamotor-anoshanda nesimba kwakanganisa kudiwa kweSintered NdFeB magineti zvinhu. NdFeB magineti echigarire, nekuita kwawo kwakasarudzika kwakazara, anogona kuwedzera zvakanyanya simba remota, uye zvinofungidzirwa kuti kudiwa kwepasirese kwepamusoro-kuita NdFeB kuchapfuura 360,000 matani panosvika 2030.

Kupesana nekumashure kweiyo mbiri kabhoni zano, maindasitiri echigarire magineti mota anozobuda seimwe yeanokurumidza kukura zvikamu. Zvinotarisirwa kuti mukati memakore mashanu anotevera, mwero wekupinda kwemagineti isingawanzo pasi pechigarire magineti muindasitiri yemotokari chikamu uchapfuura 20%, zvichikonzera kuwedzera kweNdFeB kushandiswa kwematani angangoita zviuru makumi mashanu. Kuzadzisa ichi chinodikanwa, indasitiri inoda:

Kuvandudza maratidziro ekuita kweNdFeB zvinhu, senge yakakwira magineti simba chigadzirwa uye yakakwirira-tembiricha kuramba.
Gadzira maChinese-branded rare Earth anogara magineti mota kuti uvandudze chigadzirwa mhando uye kuvimbika.
Gadzirisa yakakwira-abundance magineti tekinoroji, senge magineti anodzvanywa anopisa uye novel iron-cobalt-based magineti.
Gadzira huwandu hwakazara hwemagineti echigarire uye zvikamu kuti zvigadzire zvakamisikidzwa zvechigadzirwa zvakatemwa.
Kuvandudza nhungamiro dzekushandisa uye zviyero zvechigarire magineti zvinhu kusimudzira budiriro yemaindasitiri.
Gadzira yakazara maindasitiri cheni chimiro kutyaira iyo yepamusoro-yemhando yekusimudzira yeakakwira-inoshanda maindasitiri anogara magineti mota.
Sechikamu chakakosha chezvisingawanzo kushanda zvepasi, zvisingawanzo pasi zvechigarire magineti zvichaunza nguva nyowani yemhando yepamusoro yekusimudzira, inokurudzirwa nemusika kudiwa uye kuzvidzora kweindasitiri.
