Zvichitungamirirwa nezvinangwa zviviri zvekabhoni, hurumende yakaunza mitemo inodiwa yekushandisa simba zvakanaka uye matanho ekukurudzira kuchengetedza simba uye kuderedza utsi muindasitiri yemotokari. Ruzivo rwazvino runoratidza kuti mota dzemaindasitiri dzine IE3 zvichikwira dzakakurumidza kuwana mukurumbira nekuda kwezvirongwa zvematongerwo enyika, panguva imwe chete zvichikurudzira kukura kwakajeka kwezvinhu zvemagineti zve sintered neodymium-iron-boron (NdFeB).
Muna 2022, kugadzirwa kwemota dzinoshandisa simba shoma dzeIE3 zvichikwira kwakawedzera ne81.1% gore negore, ukuwo dzemota dzinoshandisa IE4 zvichikwira ne65.1%, nekutengeswa kunze kwenyika kwakawedzerawo ne14.4%. Kukura uku kunokonzerwa nekuitwa kwe "Motor Energy Efficiency Improvement Plan (2021-2023)", iyo ine chinangwa chekuwana kugadzirwa kwegore negore kwemota dzinoshandisa simba shoma dzinosvika mamiriyoni 170 kW panosvika 2023, zvichiita kuti pave neanopfuura 20% emota dziri kushanda. Pamusoro pezvo, kusimbiswa kweGB 18613-2020 standard kunoratidza kuti indasitiri yemota yemuno inopinda munguva yekushanda nesimba kwepamusoro.
Kuwanda kwemaIE3 nemamota anoshandisa simba shoma kupfuura aya kwakakanganisa kudiwa kwezvinhu zveNdFeB zvinogadzirwa nemagetsi. Magneti anogara aripo eNdFeB, nekushanda kwawo kwakazara, anogona kuwedzera zvakanyanya kushanda zvakanaka kwemagetsi, uye zvinofungidzirwa kuti kudiwa kwepasi rose kweNdFeB inoshanda zvakanyanya kuchapfuura matani 360,000 panosvika gore ra2030.
Zvichienderana nehurongwa hwe dual carbon, ma industrial permanent magnet motors achabuda seimwe yezvikamu zviri kukura nekukurumidza. Zvinotarisirwa kuti mukati memakore mashanu anotevera, huwandu hwe rare earth permanent magnet motors mu industrial motors huchapfuura 20%, zvichikonzera kuwedzera kwekushandiswa kweNdFeB kwematani angangoita 50,000. Kuti zvizadzise kudiwa uku, indasitiri iyi inofanira:
Wedzera zviratidzo zvekushanda kwezvinhu zveNdFeB, zvakaita sechigadzirwa chine simba remagineti rakawanda uye kuramba kupisa kwakanyanya.
Gadzirai mota dzemagineti dzinogara kwenguva refu dzemhando yerare earth dzinoshandiswa kuChina kuti dzivandudze kunaka kwechigadzirwa uye kuvimbika kwacho.
Gadzira matekinoroji emagineti ane simba rakawanda, akadai semagineti anodzvanywa nekupisa uye magineti matsva ane iron-cobalt.
Gadzira mhando dzakazara dzemagineti anogara kwenguva refu uye zvikamu kuti zvigadzire zvinodiwa zvechigadzirwa.
Kuvandudza nhungamiro dzekushandiswa uye mwero wezvinhu zvinogara zviripo zvine magineti kuti zvikurudzire kufambira mberi kwemaindasitiri.
Gadzira chimiro chakakwana checheni yemaindasitiri kuti chitungamire kugadzirwa kwemota dzemagineti dzemaindasitiri dzinoshanda zvakanaka.
Sechikamu chakakosha chezvinhu zvinoshanda zve rare earth, zvinhu zve rare earth zvinogara kwenguva refu zvine magineti zvichaunza nguva itsva yekuvandudzwa kwemhando yepamusoro, zvichikurudzirwa nekudiwa kwemusika uye kuzvitonga kweindasitiri.
