He aha nā mea magnet i hoʻohana mau ʻia i loko nā moto magnet mau?

ʻO nā mea magnet paʻa mau i hoʻohana pinepine ʻia i loko o ka kaʻa me nā magnet sintered a me nā mea hoʻopaʻa paʻa, ʻo nā ʻano nui he alumini-nickel-cobalt, ferrite, samarium cobalt, NdFeB a pēlā aku.

Alnico: ʻO Alnico mau mea magnet ka mea mua loa a hoʻohana nui ʻia, a ʻo kāna kaʻina hana hoʻomākaukau a me ka ʻenehana i kēia manawa, aia nā hale hana ma Iapana, ʻAmelika Hui Pū ʻIa, ʻEulopa, Rusia a me Kina. ʻO nā ʻoihana hana, ʻo ka hoʻopuka o Hangzhou permanent magnet ka mea mua ma Kina, me ka mana makahiki o 3000 tons.
Paa mau magnet ferrite mea: komo i ka 50's, ferrite hoomaka e ulu, o ka oi aku ma ka 70's, i coercivity, manakia ikehu mīkini hana maikaʻi strontium-ferrite i loko o ka hana i loko o ka nui helu, wikiwiki hoʻonui i ka hoʻohana 'ana i ka paʻa magnet ferrite. he mea nonmetallic magnetic, ʻaʻole maʻalahi ka ferrite e oxidize e like me nā mea metala mau loa, ka haʻahaʻa Curie haʻahaʻa a me ke kumukūʻai kiʻekiʻe, no laila kaulana loa ia.
Samarium cobalt mea: ke ala o ka 20th kenekulia i ka waena o 1960s, maikaʻi loa magnetic mau mea paʻa, a me ka paʻa loa performance.Samarium cobalt mea pono no ka manufacturing o ka uila motors mai ka hiʻona o magnetic waiwai, akā, ma muli o kona kiʻekiʻe. ke kumu kūʻai, hoʻohana nui ʻia i ka noiʻi a me ka hoʻomohala ʻana o ka mokulele, aerospace, nā mea kaua a me nā kaʻa uila ʻē aʻe a me ka hana kiʻekiʻe a me ke kumukūʻai ʻaʻole ia ke kumu nui o ka ʻenehana kiʻekiʻe o nā kaʻa uila.
NdFeB mea: NdFeB mea magnetic he neodymium, iron oxide a me nā mea hoʻohui ʻē aʻe, i ʻike ʻia he kila magnetic. i mea e hana ai i na mea kani, electroacoustic motors, magnetic separation a me ka magnetization lako miniaturization, māmā kaumaha, lahilahi lilo hiki. It is prone i ka rust ma muli o kona kiʻekiʻe maʻiʻo o neodymium a me ka iron.Surface kemikala passivation kekahi o ka maikai loa.
Loaʻa iā JIUYUAN ka hui R&D me nā makahiki he 20 mau makahiki ma liʻiliʻi brushless dc motor,waho rotor brushless dc motor,i loko o lokor brushless dc motor.Kāhea iā mā˚ouno ka ʻike kikoʻī.
