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.
