O a mea maneta e masani ona fa'aogaina i totonu afi maneta tumau?

O mea maneta tumau e masani ona faʻaaogaina i totonu o le afi e aofia ai maneta sintered ma maneta faʻapipiʻi, o ituaiga autu o alumini-nickel-cobalt, ferrite, samarium cobalt, NdFeB ma isi.

Alnico: Alnico mea maneta tumau o le mea muamua ma lautele faaaogaina maneta tumau mea, ma lona faagasologa sauniuniga ma tekinolosi e matua matua. I le taimi nei, o loo i ai falegaosimea i Iapani, le Iunaite Setete, Europa, Rusia ma Saina.Among le tele-fua gaosiga pisinisi, o le gaosiga o le maneta tumau Hangzhou o le taimi nei o le muamua i Saina, faatasi ai ma le gafatia faaletausaga o 3000 tone.
Maneta tumau mea ferrite: ulu atu i le 50's, ferrite na amata ona olaola, aemaise lava i le 70's, i coercivity, faʻaogaina masini malosi faʻamaneta sili atu strontium-ferrite i le gaosiga i le tele o numera, faʻalauteleina vave le faʻaogaina o le maneta tumau ferrite.As se mea maneta nonmetallic, ferrite e le faigofie ona oxidize e pei o mea maneta tumau uamea, maualalo Curie vevela ma tau maualuga, o lea e matua lauiloa.
Samarium cobalt material: o le tulaʻi mai o le 20th seneturi i le ogatotonu o 1960s, sili ona lelei maneta maneta meafaitino, ma faʻataunuʻu tele le faatinoga.Samarium cobalt e sili ona talafeagai mo le gaosiga o afi eletise mai le itu o meatotino mageta, ae ona o lona maualuga tau, e masani ona faʻaaogaina i le suʻesuʻega ma le atinaʻeina o vaalele, aerospace, auupega ma isi afi eletise faamiliteli ma le maualuga o le faatinoga ma le tau e le o le mea autu lea i le maualuga-tech fanua o afi eletise.
NdFeB mea: NdFeB mea maneta o le neodymium, u'amea oxide ma isi u'amea, e ta'ua foi o le maneta steel.With oloa maneta maualuga tele ma le lelei o le malosi maualuga density, NdFeB mea maneta tumau ua faaaogaina lautele i alamanuia faaonaponei ma tekinolosi faaeletonika, ina ia faia meafaigaluega, electroacoustic motors, tuueseeseina maneta ma masini magnetization miniaturization, mama mama, manifinifi avea possible.It e faigofie ona elea ona o lona tulaga maualuga o le neodymium ma iron.Surface chemical passivation o se tasi o fofo sili.
JIUYUAN ei ai R & D 'au ma sili atu i le 20 tausaga aafiaga i luga tama'i pulumu dc afi,i fafo rotor brushless dc afi,i totonu rotor brushless dc afi, brushless dc afi ma le pule poʻo le taʻavale ma isi.Faafesootai matoumo fa'amatalaga auiliili.
