Kugwiritsa ntchito maginito a neodymium mumagetsi amagetsi
Masiku ano, ndizofala kwambiri kugwiritsa ntchito maginito a neodymium m'magalimoto amagetsi kwakwera kwambiri, makamaka chifukwa cha kuchuluka kwa magalimoto amagetsi pamsika wapadziko lonse lapansi wamagalimoto.
Ma motors amagetsi ndi matekinoloje atsopano osinthika ali patsogolo ndipo maginito ali ndi gawo lofunika kwambiri lomwe liyenera kuchita mtsogolo mwamakampani ndi zoyendera zapadziko lonse lapansi.Maginito a Neodymium amakhala ngati stator kapena gawo la mota yamagetsi yachikhalidwe yomwe simayenda.Ma rotor, gawo losuntha, lingakhale cholumikizira chamagetsi chosuntha chomwe chimakoka ma pod mkati mwa chubu.
Mumagetsi amagetsi, maginito a neodymium amachita bwino pamene ma motors ali ang'onoang'ono komanso opepuka.Kuchokera pa injini yomwe imazungulira DVD disc kupita ku mawilo a galimoto yosakanizidwa, maginito a neodymium amagwiritsidwa ntchito m'galimoto yonse.
Maginito a neodymium okhala ndi kukakamiza pang'ono akhoza kuyamba kutaya mphamvu ngati atenthedwa kupitirira 80 ° C.High coercivity neodymium maginito apangidwa kuti azigwira ntchito pa kutentha mpaka 220 ° C, ndi kutaya pang'ono kosasinthika.Kufunika kocheperako kutentha kwa maginito a neodymium kwapangitsa kuti magiredi angapo apangidwe kuti akwaniritse zofunikira zogwirira ntchito.
M'magalimoto onse komanso m'mapangidwe amtsogolo, kuchuluka kwa magalimoto amagetsi ndi solenoids kuli bwino muzithunzi ziwiri.Amapezeka, mwachitsanzo, mu:
- Ma motors amagetsi a mawindo.
-Ma motors amagetsi a wiper za windscreen.
-Njira zotsekera zitseko.
Chimodzi mwazinthu zofunika kwambiri pamagetsi amagetsi ndi maginito a neodymium.Maginito nthawi zambiri amakhala gawo lokhazikika la mota ndipo amapereka mphamvu yokana kuti ipangitse kuyenda kozungulira kapena kozungulira.
Maginito a Neodymium mu ma mota amagetsi ali ndi zabwino zambiri kuposa maginito amitundu ina, makamaka m'magalimoto apamwamba kwambiri kapena pomwe kuchepetsa kukula ndikofunikira.Pokumbukira kuti matekinoloje atsopano onse akufuna kuchepetsa kukula kwazinthu zonse, ndizotheka kuti ma injiniwa atenga msika wonse posachedwa.
Maginito a Neodymium amagwiritsidwa ntchito mochulukira pamsika wamagalimoto, ndipo idakhala njira yabwino yopangira maginito atsopano agawoli.
Kusuntha kwapadziko lonse pakupanga magetsi pamagalimoto kukupitilizabe.Mu 2010, kuchuluka kwa magalimoto amagetsi m'misewu yapadziko lonse lapansi kudafika 7.2 miliyoni, pomwe 46% anali ku China.Pofika m'chaka cha 2030, chiwerengero cha magalimoto amagetsi chikuyembekezeka kukula kufika pa 250 miliyoni, kukula kwakukulu mu nthawi yochepa kwambiri.Ofufuza a mafakitale amawoneratu kukakamizidwa kwa zinthu zofunika kwambiri kuti akwaniritse zofunikirazi, kuphatikizapo maginito osowa padziko lapansi.
Maginito osowa padziko lapansi amagwira ntchito yofunika kwambiri pamagalimoto oyendetsedwa ndi ma injini amagetsi oyaka ndi magetsi.Pali zigawo ziwiri zofunika kwambiri mu galimoto yamagetsi yomwe imakhala ndi maginito osowa padziko lapansi;ma motors ndi masensa.Cholinga chake ndi Motors.
Magalimoto amagetsi oyendetsedwa ndi batri (EVs) amathamangitsidwa kuchokera ku mota yamagetsi m'malo mwa injini yoyaka mkati.Mphamvu yoyendetsa galimoto yamagetsi imachokera ku paketi yaikulu ya batri yothamanga.Kuti muteteze ndi kukulitsa moyo wa batri, mota yamagetsi iyenera kugwira ntchito bwino kwambiri.
Maginito ndi gawo loyambirira lamagetsi amagetsi.Injini imagwira ntchito ngati waya wa waya, wozunguliridwa ndi maginito amphamvu, amazungulira.Mphamvu yamagetsi yomwe imapangidwira mu coil imatulutsa mphamvu yamagetsi, yomwe imatsutsana ndi mphamvu ya maginito yomwe imatulutsidwa ndi maginito amphamvu.Izi zimapanga zinthu zonyansa, monga kuyika maginito awiri akumpoto pafupi ndi mzake.
Kuthamangitsidwa kumeneku kumapangitsa kuti koyiloyo ikhale yozungulira kapena kuzungulira pa liwiro lalikulu.Koyiloyi imamangiriridwa ku ekseli ndipo kuzungulira kumayendetsa mawilo agalimoto.
Ukadaulo wa maginito ukupitilizabe kusinthika kuti ukwaniritse zofuna zatsopano zamagalimoto amagetsi.Pakalipano, maginito abwino kwambiri omwe amagwiritsidwa ntchito m'magalimoto a magalimoto osakanizidwa ndi magalimoto amagetsi (mwa mphamvu ndi kukula kwake) ndi Rare Earth Neodymium.Dysprosium yofalikira m'malire a tirigu imapangitsa kuti pakhale mphamvu zambiri, zomwe zimapangitsa kuti pakhale machitidwe ang'onoang'ono komanso ogwira ntchito.
Galimoto yapakati pa haibridi kapena yamagetsi imagwiritsa ntchito pakati pa 2 ndi 5 kg ya maginito a Rare Earth, kutengera kapangidwe kake.Maginito a Rare Earth amapezeka mu:
-Kutentha, mpweya wabwino ndi mpweya (HVAC);
- Chiwongolero, kufala ndi mabuleki;
- Injini ya Hybrid kapena chipinda chamagetsi chamagetsi;
-Zomverera monga chitetezo, mipando, makamera, etc;
- Khomo ndi mawindo;
-Zosangalatsa dongosolo (okamba, wailesi, etc);
-Mabatire agalimoto amagetsi
-Makina amafuta ndi utsi a Hybrids;
Pofika chaka cha 2030, kukula kwa magalimoto amagetsi kudzachititsa kuti pakhale kufunikira kwa maginito.Pamene ukadaulo wa EV ukukula, maginito omwe alipo amatha kuchoka ku maginito osowa padziko lapansi kupita kumakina ena monga kusafuna kusintha kapena maginito a ferrite.Komabe, zikuyembekezeredwa kuti maginito a neodymium apitiliza kugwira ntchito yofunika kwambiri pakupanga ma injini a Hybrid ndi chipinda chamagetsi chamagetsi.Kuti akwaniritse kufunikira kowonjezereka kwa neodymium kwa ma EVs, akatswiri amsika amayembekezera:
-Kuchulukitsa kwa China ndi opanga ena a neodymium;
-Kupititsa patsogolo nkhokwe zatsopano;
-Kubwezeretsanso maginito a neodymium omwe amagwiritsidwa ntchito pamagalimoto, zamagetsi ndi ntchito zina;
Honsen Magnetics amapanga maginito osiyanasiyana ndi maginito.Zambiri ndi za mapulogalamu apadera.Kuti mumve zambiri pazogulitsa zomwe zatchulidwa mukuwunikaku, kapena ma bespoke maginito agulu ndi mapangidwe amagetsi, chonde titumizireni imelo yafoni.
