Kiʻekiʻe ʻO Neodymium Arc Magnet no DC Motor

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. I ka loaʻa ʻole ʻana o kahi māla magnetic waho, hiki ke hoʻohālikelike 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 ke kuhikuhi magnetization spontaneous a me ke kuhikuhi o ke kahua magnetic waho e hoʻonui liʻiliʻi me ka hoʻonui ʻana o ka pā magnetic i noi ʻia a hoʻohuli hou i ka kuhikuhi magnetization o ka arc. magnet i ke kuhikuhi o ke kahua hoʻokele waho.
