Ko te Magnet NDFEB Ndfeb

Kua rite Sintered NdFeB aukume i te rauemi raw e rewa i roto i te oumu, maka ki te pokepokea ai, me te matao o ki te puka ingots. E heke ana nga ingots me paräoa; Kei te ka sintered te puehu ki poraka mātotoru. Na he wera-tukinotia, tapahia nga poraka ki te āhua, mata tukinotia me magnetized.

Ka rite ki o 2012, kua hua 50,000 taranata o aukume neodymium mana ia tau i roto i Haina, a 80,000 taranata i roto i te hanga-ake "kamupene-e-kamupene" mahi i roto i te 2013. China hua neke atu i 95% o ngā huānga whenua onge, me hua e pā ana ki 76% o te katoa aukume onge-whenua o te ao.

E mākahia aukume Neodymium rite ki o ratou hua pūngao mōrahi, e pā ana ki te putanga rere autō ia rōrahi wae. tohu uara Higher aukume kaha me ngā i N35 ake ki N52. Letters e whai ake nei i te kōeke tohu pāmahana mōrahi whakahaere (maha te pāmahana Curie), e ngā i M (ki runga, ki te 100 ° C) ki EH (200 ° C).

whangai ana Sintered Nd2Fe14B ki kia whakaraerae ki te waikura, rawa me rohe witi o te aukume sintered. Tenei momo o te waikura e taea meinga ino nui, tae atu meake o te aukume ki te puehu o matūriki iti autō, ranei spallingof te apa mata.
whakatutukihia ana tēnei whakaraeraetanga i roto i maha hua arumoni mā te tāpiri i te paninga paruru ki te ārai i te rongo ki te kōhauhau. Nika whakakikorua e rua-paparanga whakakikorua parahi-konukoreko ranei ko nga tikanga paerewa, ahakoa whakakikoruatia ki ētahi atu konganuku, ranei polymer me te kararehe coatings tiaki e hoki i roto i te whakamahi.

Kua whakakapi aukume Neodymium alnico me aukume ferrite i tokomaha o nga tono mano i roto i te hangarau hou te wahi e hiahiatia ana aukume kaha tūturu, no te mea taea to ratou kaha nui te whakamahi o iti, aukume mama hoki te tono i homai. Ētahi tauira ko:
actuators Head mō kōpae mārō rorohiko
Magnetic atahanga te kōwarotanga (MRI)
whakakā pupuhi e-hikareti Mechanical
Locks mō tatau
Loudspeakers me taringa
ahunga Magnetic me hononga

Actuators
generators Electric mō kapohau hau (anake te hunga ki te excitation aukume pūmau)
rapu c Direct-puku kapohau hau. 600 kg o PM rauemi ia megawatt
Turbines whakamahi nihowhiti rapu rauemi PM iti ia megawatt
