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 kahi 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 loko o ke kahua kaʻa kaʻa magnet mau loa, ʻoi aku ka nui o nā mea kaʻa kaʻa mau loa NdFeB hiki ke hoʻohālikelike i nā ʻano ʻano ʻano like ʻole a me nā kaʻa kaʻa 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). ʻO kā mākou hui i hana i ka moto (rotor) shaft i ka hoʻomaka ʻana, a i mea e lawelawe maikaʻi aku ai i nā mea kūʻai aku, ua hoʻomaka mākou e hōʻuluʻulu i nā magnets me nā shaft rotor ma hope aku i mea e hoʻokō ai i ka noi mākeke ma 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: ka hale squirrel 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. Hoʻokumu ka flux i kahi māla magnetic i ka 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. ʻO ke au pololei (DC) ke alakaʻi nei i ke kahua o kēia manawa i hoʻokahi ʻaoʻao, a hāʻawi ʻia i ka wili uea e kahi hui o nā pulupulu a me nā apo paheʻe. E like me nā mea magnet, ʻo ke kahua 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 hope a i ʻole counterclockwise.
