Kiʻekiʻe ʻO Neodymium Arc Magnet no DC Motor
Hōʻike huahana
Ua kapa ʻia ʻo Neodymium Arc Magnets he māhele magnet a i ʻole nā magnet curved.
Hoʻohana nui ʻia nā magnet Arc e like me nā kaʻa DC magnet mau loa.ʻAʻole like me nā kaʻa electromagnetic e hoʻohua ai i nā kumu mana ma o ka excitation coils, ʻoi aku ka maikaʻi o ka arc permanent magnet ma mua o ka excitation uila, hiki ke maʻalahi i ka mīkini i ke ʻano, kūpono i ka mālama ʻana, māmā i ke kaumaha, liʻiliʻi i ka nui, hilinaʻi i ka hoʻohana, a haʻahaʻa. i ka hoohana ikehu.
Aia kahi "hoʻopili hoʻololi" ikaika ma waena o nā electrons pili i kahi mea ferromagnetic.Inā ʻaʻole i loaʻa kahi māla magnetic o waho, hiki ke hoʻopili ʻia kā lākou mau manawa magnetic spine ma kahi wahi liʻiliʻi.e ala aʻe e hana i nā wahi liʻiliʻi o ka hoʻokalakupua ʻana, i kapa ʻia ʻo arc magnets.I loko o ka unmagnetized ferromagnetic mea, ʻoiai kēlā me kēia arc magnet he definite spontaneous magnetization kuhikuhi i loko a me ka nui magnetism, nā kuhikuhi magnetization o ka nui o ka arc magnets okoa, no laila, ka mea holoʻokoʻa ferromagnetic mea ole hōʻike magnetism.
Aia ka electromagnet i loko o ke kahua magnetic o waho, ʻo ka nui o ka arc magnet nona ka ʻaoʻao magnetization kuʻuna a me ke kuhikuhi o ke kahua magnetic waho e hoʻonui liʻiliʻi me ka hoʻonui ʻana o ke kahua magnetic i hoʻopili ʻia a hoʻohuli hou i ka kuhikuhi magnetization o ka arc. magnet i ke kuhikuhi o ke kahua hoʻokele waho.
ʻO Arc NdFeB Mākēneki ʻano
1. Kiʻekiʻe Hana wela
No ka SH series NdFeB magnets, hiki ke piʻi ka mahana hana kiʻekiʻe i 180 ℃.ʻO ka hana o ke kaʻa ka hopena maʻamau i nā wela kiʻekiʻe.Hiki iā ʻoe ke koho i nā mea hoʻokalakupua kiʻekiʻe e hoʻololi i ka mahana hana o ka mīkini e pale aku i ka demagnetization o ka magnet ma muli o ke kiʻekiʻe o ka wela hana.

2. Hoʻopalapala / Plating
Nā koho: Ni-Cu-Ni, Zinc (Zn), Black Epoxy, Rubber, Gold, Silver, etc.
3. Aʻo Magnetic
Hoʻokaʻawale ʻia nā manaʻo Arc e nā ʻano ʻekolu: Outer Radius (OR), Inner Radius (IR), Kiʻekiʻe (H), a me ka Angle.
Aʻoaʻo mākēneki o nā mākēneki arc: hoʻokaʻina axially, magnetized diametrically, a me radially magnetized.
