I ka hana pūʻulu, ʻike pinepine mākou i kēia kūlana: i kekahi manawa ʻike ʻia nā kīnā ʻokoʻa ma muli o ke kumu like, a i kekahi manawa hiki mai ka hemahema ma muli o nā kumu like ʻole.
Hoʻokumu ʻia ka ikaika electromotive hope ma ke kūʻē ʻana i ke ʻano o ke au i ka wili e loli. Hoʻokumu ʻia ka ikaika electromotive hope ma kēia mau ʻano: (1) ke hele ʻia kahi au i loko o ka wili;
ʻO nā hiʻohiʻona o nā huahana kaʻa ka noho mālie o ka stator a me ka neʻe ʻana o ka rotor i ka wā o ka hana. ʻO ka mea maʻamau, hoʻohana mākou i nā ʻāpana paʻa e like me ka hoʻokomo a i ʻole ka puka o ka mana.
ʻAʻole hiki i nā bearings pōleʻa hohonu ke amo i nā ukana axial koʻikoʻi, no laila, hoʻohana nui ʻia nā bearings pili i ke kihi (ʻike ʻia ʻo thrust bearing) ma ke ʻano he ʻimi ʻana i nā bearings i nā kaʻa kū pololei.
I ka hana ʻana a me ka hana ʻana o nā kaʻa, i mea e loaʻa ai nā pono hana o kekahi mau ʻāpana, hoʻohana ʻia nā kaʻina hana wela i kekahi manawa. Nā mea like ʻole, nā ʻāpana like ʻole,
Inā ua loaʻa iā ʻoe ka manawa e komo ai i ka hoʻāʻo ʻana o nā kaʻa, hiki iā ʻoe ke ʻike hohonu i ka ʻenehana hoʻololi pinepine. ʻOi aku ka poʻe i ʻike i nā mea hoʻāʻo kahiko e hiki ke manaʻo maikaʻi i nā pono o ka ʻenehana hoʻololi pinepine.
ʻO nā bearings o nā kaʻa, inā paha mākou he mea hana kaʻa a mea hoʻohana kaʻa paha, ʻike mākou a pau no nā kaʻa kaumaha kaumaha, e hoʻohana ʻia nā bearings cylindrical roller ma ka hope o ka hoʻonui ʻia ʻana o ke kaʻa, a no ka mea.
