Nā hiʻohiʻona hana o nā pulupulu kalapona

Nā hiʻohiʻona hana onā pulupulu kalapona

ʻO ka hana o ka pulupulu kalapona ka mea nui e alakaʻi i ka uila i ka wā e hamo ana i ka metala. ʻAʻole ia e like me ka wā e hamo ai me ka hoʻoheheʻe ʻana i ka uila i ka metala; ʻAʻole hiki i nā pulupulu kalapona no ka mea ʻelua mau mea like ʻole ke kalapona a me ka metala. Hoʻohana ʻia ka hapa nui o kāna hoʻohana ʻana i nā kaʻa, a he ʻano like ʻole nā ​​ʻano, ʻehā a me nā pōʻai, a pēlā aku.

Palaki kalaponaHe kūpono ia no nā ʻano kaʻa like ʻole, nā mīkini hana, a me nā mīkini axle. Loaʻa iā ia ka hana hoʻohuli maikaʻi a me ke ola lawelawe lōʻihi. Hoʻohana ʻia ka pulupulu kalapona ma ka commutator a i ʻole ke apo slip o ke kaʻa. Ma ke ʻano he kino hoʻoheheʻe e alakaʻi a lawe mai i kēia manawa, loaʻa iā ia ka conductivity uila maikaʻi, conductivity thermal a me ka hana lubricating, a loaʻa iā ia kekahi ikaika mechanical a me ke ʻano o ka commutation sparks. Aneane nā kaʻa a pau e hoʻohana i nā palaki kalapona, kahi mea nui o ka kaʻa. Hoʻohana nui ʻia i loko o nā mea hana AC a me DC, nā kaʻa synchronous, nā kaʻa DC pākaukau, nā apo ohi kaʻa crane, nā ʻano mīkini welding a pēlā aku. Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, ʻoi aku ka nui o nā ʻano o nā kaʻa a me nā kūlana hana o ka hoʻohana

Ke kuleana kiko'ī onā pulupulu kalapona

1. Hoʻohui i ke au o waho (excitation current) i ka rotor rotating (input current) ma o ke kalapona kalapona;

2. E hoʻokomo i ka hoʻopiʻi paʻa ma luna o ke kumu nui i ka honua (grounded carbon brush) ma o ka carbon brush (output current);

3. E alakaʻi i ka lāʻau nui (ʻāina) i ka mea pale no ka pale ʻana i ka lepo rotor a ana i ka volta lepo maikaʻi a maikaʻi ʻole o ka rotor;

4. E hoʻololi i ka ʻaoʻao o kēia manawa (ma ke kaʻa commutator, hoʻokani pū ka pulupulu i ka hana o ka commutation)

Koe wale no ka induction AC asynchronous motors. Aia kekahi mau kaʻa ʻē aʻe, ʻoiai ʻo ka rotor he apo commutation.

ʻO ke kumumanaʻo o ka hana mana ʻo ia ma hope o ka ʻoki ʻana o ke kahua magnetic i ka uea, hana ʻia kahi au i ka uea. Hoʻokiʻoki ka mīkini hana i ka uwea ma ka hoʻohuli ʻana i kahi māla magnetic. ʻO ke kahua magnetic rotating ka rotor, a ʻo nā uea ʻoki ʻia ka stator.
