Chifukwa chiyani maginito a Neodymium amalimbikitsa njinga zamagetsi zodziwika ku China?Pakati pa njira zonse zoyendera, njinga yamagetsi ndi galimoto yoyenera kwambiri kumidzi ndi matauni.Ndi yotsika mtengo, yabwino, komanso yosunga zachilengedwe.
M'masiku oyambilira, chilimbikitso chachindunji cha E-bike kuti agwire moto chinali kuchepetsa njinga zamoto.Panthawi imodzimodziyo, mafakitale onyamula katundu ndi owonetseratu ali pafupi kwambiri, zomwe zalimbikitsa kufunikira kwa njinga zamagetsi.
Monga ukadaulo wapakatikati wokhudzana ndi njinga zamagalimoto amagetsi monga ma mota amagetsi ndi mabatire amakhala okhwima komanso okhazikika, makamaka kupita patsogolo kwaukadaulo komanso kupanga maginito a sintered NdFeB kumapatsa njinga zamagetsi zabwino zambiri zamagalimoto amagetsi, monga torque yayikulu, mphamvu yokwera yolimba, Kuchita bwino kwambiri, phokoso lochepa, kulephera kochepa komanso mtengo wachuma.Njira yopangira magalimoto amagetsi yatsitsidwanso, zomwe zimapangitsa kuti anthu ambiri alowe nawo msika.
Ma wheel hub motor ndi mota yamagetsi yokhala ndigudumu hub motor maginitooikidwa mu gudumu.Chinthu chake chachikulu ndi chakuti zipangizo zamagetsi, zotumizira ndi zowonongeka zimaphatikizidwa mu gudumu la magudumu, kotero kuti gawo lamakina la galimoto yamagetsi limakhala losavuta kwambiri.
Pakali pano, njinga zamagetsi ambiri amagwiritsa NdFeB osowa lapansi okhazikika maginito gudumu Motors.Koyilo yagalimoto imakondwera ndi maginito okhazikika.Mitundu yambiri yamagalimoto amagetsi amagetsi amagwiritsa ntchito iziNeodymium square maginitokukula 24×13.65x3mm ndi kalasi N35H.Seti iliyonse ya mota yamagetsi imafuna zidutswa 46 za maginito agalimoto yama wheel hub.Mmodzi wa ozungulira ndi stator maginito minda ya okhazikika maginito galimoto kwaiye ndi waya phukusi, ndi zina kwaiye ndi maginito okhazikika.Chifukwa chisangalalo cha coil sichimagwiritsidwa ntchito, chimapulumutsa mphamvu yamagetsi yomwe imagwiritsidwa ntchito ndi koyilo yosangalatsa panthawi yogwira ntchito, ndikuwongolera kusinthika kwamagetsi kwamagetsi.Izi zitha kuchepetsa kuyendetsa galimoto ndikuwonjezera mtunda wanjinga zamagetsi pogwiritsa ntchito mphamvu zochepa zokwera.
Palinso zosintha zatsopano kuzungulira 2016. Izi makamaka chifukwa cha kutuluka kwa ang'onoang'ono, apamwamba kwambiri komanso, ndithudi, magalimoto amagetsi okwera mtengo omwe akuimiridwa ndi NIU.Chimodzi mwazinthu zogulitsa za NIU ndikuti amagwiritsa ntchito mabatire a lithiamu okhala ndi kulemera kopepuka, mphamvu zazikulu komanso moyo wautali wautumiki, pafupifupi zaka zinayi kapena zisanu.Panthawiyo, kuposa 90% ya msika wamagetsi amagetsi amagwiritsa ntchito mabatire a lead-acid, ndipo kuchuluka kwa mabatire a lithiamu kunali pafupifupi 8%.Pakalipano, magalimoto akuluakulu a njinga zamagetsi ku China akuphatikizapo SUNRA, AIMA, YADEA, TAILG, LUYUAN, etc. NIU ndi NINEBOT, zomwe zimatchedwa kuti magalimoto amagetsi apamwamba kwambiri, ali ndi gawo laling'ono kwambiri la msika.Zimanenedwa kutiE-bike maginitokufunikira ndi msika wanjinga zamagetsi zidzakulanso mwachangu m'maiko okhala ndi anthu ambiri monga China, monga India.
