ʻO ke kī i ka hoʻonoho generatorkomo pū me ka motika stator, motika rotor, nā poʻo hopena, nā pulupulu kalapona, nā motika a me nā ʻolokaʻa a me nā mea ʻē aʻe. ʻO ka motika stator me ka moto motika, motika stator transformer core, wili wili wili, a me nā ʻāpana ʻē aʻe i hoʻopaʻa ʻia i kēia ʻāpana. ʻO ka rotor motika me ka motika rotor transformer core, ka pou rotor motor (me ka choke magnet, pou wili kūwili paʻa), apo paheʻe (i ʻike ʻia ʻo ke apo keleawe, apo lima ʻohi), pā uila a me ka ʻau o ka hoʻokele a me nā mea ʻē aʻe. I ka motika kaʻa e kau i ka wili ʻana o ka armature, aia ka uila ma hope o ka hoʻoulu ʻana i ka ikaika electromotive, ke hana nei i ka papa hana uila. Ma hope o ka hoʻokumu ʻana i ka pitch hoʻokomo electromagnetic e hoʻokō i ka huli ʻana o ka ikehu i kakaʻa kau kaʻa o Kahualoa Kokohi
Pono ka stator a me ka rotor i nā pono ma ka motika, ka kaʻa kau kaʻapaʻa a hoʻonoho ʻia ma ka pūpū, ʻo ka maʻa mau e hōʻeha ʻia ka stator motika me nā wili uila electromagnetic ma ka ʻaoʻao luna; Hoʻokumu ʻia ka mea hoʻokele kaʻa i nā bearings a i ʻole nā ​​bushings i kau ʻia ma ka moto motika, ke kaʻa kaʻa me ka silicon steel, nā uila uila, kahe uila i ka hopena uila hiki ke hana i ka papa electromagnetic i ka stator moto, motika rotor ma ka silicon steel, kahua electromagnetic a laila kipaku ka mahina electromagnetic i ka mea hoʻokele kaʻa e kaʻa.
