6641 DMD Papa F Ka Pepa Ho'opono Huipuia Mea Hana

ʻAʻole i kuhikuhi ʻia ke alapine o ka hoʻololi ʻana i ke kalapona. E like me ka paakiki o ke kalapona palaki ponoi

ʻO ka hoʻomau ʻana i nā kaʻina hana ʻoihana i lilo i mea nui, a ua ʻike ʻia e nā ʻāina he kumu waiwai nui ma muli o ko lākou kiʻekiʻe kiʻekiʻe a me ka waiwai waiwai, ua wehe i nā wahi no ka noiʻi ʻana i nā magnet mau loa ʻole honua. ʻO kahi kuhikuhi noiʻi hiki ke nānā i hope i nā mea hoʻokele mau loa i kūkulu ʻia, nā magnet ferrite, a e aʻo hou iā lākou me ka hoʻohana ʻana i nā mea hana a me nā ala hou i loaʻa i nā makahiki i hala iho nei. Ke hana nei kekahi mau hui i nā papahana noiʻi hou e manaʻo nei e hoʻololi i nā magnets rare-earth me nā ʻōmaʻomaʻo a ʻoi aku ka maikaʻi.

ʻO ke kuleana o ka pulupulu kalapona ʻo ia ka lawe ʻana i ka uila oiai e hamo ana i ka metala, ʻaʻole like ia me ka hana ʻana i ka uila; i ka wā e hamo ai ka metala a me ka metala a hoʻokele i ka uila, e piʻi aʻe ka ikaika o ka friction, a e hui pū nā hono; ʻAʻole hiki i nā pulupulu Carbon, no ka mea, ʻelua mau mea like ʻole ke kalapona a me ka metala.

Hoʻohana nui ʻia nā pulupulu kalapona, i kapa ʻia ʻo nā pulupulu uila, i nā mea uila he nui e like me ka hoʻopili ʻana.

Loaʻa nā noi o nā commutators i nā mīkini DC (direct current) e like me nā mea hana DC, nā kaʻa DC he nui, a me nā kaʻa honua. Ma kahi kaʻa DC, hāʻawi ka commutator i ka uila i nā wili. Ma ka hoʻololi ʻana i ka ʻaoʻao o ke au i loko o nā wiliwili ʻāwili i kēlā me kēia hapalua o ka huli ʻana, e hana ʻia kahi torque (ikaika kaapuni mau).
