ʻO ke kuleana o nā pulupulu kalapona i nā kaʻa


Hoʻohana ʻia nā pulupulu kalapona ma waena o nā ʻāpana paʻa a me nā ʻāpana o nā kaʻa, nā mea hana a i ʻole nā ​​​​mīkini wili ʻē aʻe a lilo i hoʻokahi o kāna mau mea nui. Ma ke ʻano he sliding contact, hoʻohana nui ʻia nā pulupulu kalapona i nā mea uila he nui. ʻO nā mea huahana he graphite electrochemical, graphite greased, metala (me ke keleawe, kālā) graphite. He ʻehā ke ʻano, a hoʻokomo ʻia ka uea metala i ka pūnāwai. ʻO ka pulupulu kalapona he ʻāpana hoʻoheheʻe ʻia, no laila maʻalahi ke ʻaʻahu a pono e hoʻololi a hoʻomaʻemaʻe mau.

ʻO ke kuleana o ka pulupulu kalapona ʻo ia ka hoʻokomo ʻana i ka manawa rotor i koi ʻia e ka hana kaʻa i loko o ka wili rotor ma o ka ʻāpana hoʻohui ma ke apo slip. ʻO ke kūpono a me ka maʻalahi o ka pulupulu kalapona a me ka ʻāpana pili, a me ka nui o ka ʻili pili e pili ana i kona ola a me ka hilinaʻi. I loko o kahi kaʻa DC, hana pū ʻo ia i ka hana o ka hoʻololi ʻana (hoʻoponopono) i ka ikaika electromotive hoʻololi i hoʻokomo ʻia i ka wili armature.

Hoʻokumu ʻia ka commutator me nā pulupulu a me nā apo commutation, a ʻo nā pulu kalapona kekahi ʻano o nā pulupulu. Ma muli o ka hoʻololi ʻana o ka rotor, ʻānai mau ʻia nā pulupulu me ke apo commutation, a e hiki mai ana ka hili ʻana i ka manawa o ka hoʻololi ʻana, no laila ʻo nā pulupulu nā ʻāpana komo i loko o ka mīkini DC.
