ʻO Rotor Magnetic, a i ʻole rotor magnet mau loa ka ʻāpana kū ʻole o kahi kaʻa.ʻO ka rotor ka ʻāpana neʻe i loko o kahi kaʻa uila, generator a me nā mea hou aku.Hoʻolālā ʻia nā rotors magnetic me nā pou he nui.Hoʻololi kēlā me kēia pou i ka polarity ('ākau & hema).Huli nā pou kū'ē i kahi kiko waena a i ʻole axis (ma ke ʻano, aia kahi kumu i waenakonu).ʻO kēia ka hoʻolālā nui no nā rotors.Loaʻa iā Rare-earth permanent magnetic motor kekahi ʻano o nā pono, e like me ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka hana kiʻekiʻe a me nā ʻano maikaʻi.Nui loa kāna mau noi a hoʻonui i nā wahi āpau o ka mokulele, ka lewa, ka pale, ka hana ʻana i nā mea hana, ka hana ʻoihana a me ka mahiʻai a me ke ola o kēlā me kēia lā.
Hoʻopuka nui ʻo Honsen Magnetics i nā ʻāpana magnetic i ke kahua kaʻa kaʻa paʻa mau, ʻoi aku ka nui o NdFeB mau mea hoʻokele kaʻa paʻa paʻa e hiki ke hoʻohālikelike i nā ʻano ʻano ʻano like ʻole a me nā ʻenekini paʻa mau loa.Ma waho aʻe, i mea e hōʻemi ai i ka pōʻino o ka electromagnetic eddy current i nā magnet, hana mākou i nā magnet laminated (multi splice magnets).Ua hana kā mākou hui i ka moto (rotor) shaft i ka hoʻomaka ʻana, a i mea e lawelawe maikaʻi ai i nā mea kūʻai aku, ua hoʻomaka mākou e hōʻuluʻulu i nā magnets me nā rotor shafts ma hope i mea e hoʻokō ai i ka noi mākeke i ka hana kiʻekiʻe a me ke kumu kūʻai haʻahaʻa.
ʻO ka rotor kahi mea hoʻoneʻe o kahi ʻōnaehana electromagnetic i loko o ke kaʻa uila, ka uila uila, a i ʻole ka alternator.ʻO kona hoʻololi ʻana ma muli o ka launa pū ʻana ma waena o nā wiliwili a me nā māla magnetic e hoʻopuka ai i kahi torque a puni ke axis o ka rotor.
Induction (asynchronous) motors, generators and alternators (synchronous) loaʻa kahi ʻōnaehana electromagnetic i loaʻa i kahi stator a me ka rotor.ʻElua mau hoʻolālā no ka rotor i loko o kahi kaʻa induction: squirrel cage a me ka ʻeha.I nā mea hana a me nā mea hoʻololi, ʻo nā hoʻolālā rotor he pou salient a cylindrical paha.
I loko o ka mīkini hoʻokomo ʻekolu ʻāpana, ʻo ka ʻokoʻa i hāʻawi ʻia i nā wili stator e hoʻoikaika iā ia e hana i kahi ʻano hoʻololi magnetic.Hoʻopuka ka flux i kahi māla magnetic ma ka ʻae ea ma waena o ka stator a me ka rotor a hoʻoulu i kahi voli e hoʻopuka i kēia manawa ma o nā pahu rotor.Hoʻopili ʻia ke kaapuni rotor a ke kahe nei kēia manawa i nā conductors rotor.ʻO ka hana o ka holo ʻana a me ke au e hoʻopuka i kahi ikaika e hoʻohua ai i kahi torque e hoʻomaka ai i ke kaʻa.
Hana ʻia ka rotor alternator me kahi wili uwea i hoʻopuni ʻia a puni kahi kumu hao.Hana ʻia ka ʻāpana magnetic o ka rotor mai nā lamination kila e kōkua i ka hoʻopaʻa ʻana i nā pahu conductor i nā ʻano kikoʻī a me nā nui.I ka holo ʻana o nā au ma ka wili uea, ua hana ʻia kahi māla magnetic a puni ke kumu, i kapa ʻia ʻo ia ka field current.ʻO ka ikaika o kēia manawa e hoʻomalu i ka pae mana o ke kahua magnetic.Hoʻokuʻu ʻia ke au pololei (DC) i ke ʻano o ke kahua i hoʻokahi ʻaoʻao, a hāʻawi ʻia i ka wili uea e kahi hui o nā pulupulu a me nā apo slip.E like me nā mea magnet, ʻo ka māla magnetic i hana ʻia he pole ʻākau a me ka hema.Hiki ke hoʻohana ʻia ka ʻaoʻao maʻamau o ka uaki ma ka hoʻohana ʻana i nā magnets a me nā māla magnetic i hoʻonohonoho ʻia i ka hoʻolālā ʻana o ka rotor, e ʻae ana i ka holo ʻana o ke kaʻa ma ka ʻaoʻao ʻaoʻao a i ʻole.
