ʻO ka hana kikoʻī o nā pulupulu kalapona

Palaki kalapona, i kapa ʻia ʻo nā pulupulu uila, hoʻohana nui ʻia i nā mea uila he nui e like me ka hoʻopili ʻana. ʻO nā mea nui i hoʻohana ʻia no nā pulu kalapona i nā huahana he graphite, graphite greased, a me ka metala (me ke keleawe, ke kālā) graphite. ʻO ka pulupulu kalapona he mea ia e hoʻoili ai i ka ikehu a i ʻole nā ​​hōʻailona ma waena o ka ʻāpana paʻa a me ka ʻāpana kaʻa o ka motika a i ʻole ka mīkini hana ʻē aʻe. Hana ʻia ia me ke kalapona maʻemaʻe a me ka coagulant. Aia kahi punawai e kaomi ma luna o ka ʻauahi ʻaupuni. Ke hoʻololi ka motika, hoʻouna ʻia ka ikehu uila i ka coil ma o ka commutator. No ka mea, he kalapona kona mea nui, i kapaiakalapona kalapona, maʻalahi ke komo. Pono e mālama mau ʻia a hoʻololi ʻia, a e hoʻomaʻemaʻe ʻia nā waihona kalapona.
1. Hoʻohana ʻia ke ʻano o waho (excitation current) i ka rotor wili ma o kakalapona kalapona(hookomo i keia manawa);
2. E hoʻokomo i ka hoʻopiʻi paʻa ma ke kumu nui i ka honua ma o ka pulupulu kalapona (palapala kalapona honua) (ke manawa hoʻopuka);
3. E alakaʻi i ka lāʻau nui (ka honua) i ka mea pale no ka pale ʻana i ka lepo rotor a ana i ka uila maikaʻi a maikaʻi ʻole o ka rotor i ka honua;
4. E hoʻololi i ka ʻaoʻao o kēia manawa (ma nā kaʻa kaʻa commutator, pāʻani pū nā pulupulu i kahi hana commutation).
Ma waho aʻe o ka induction AC asynchronous motor, ʻaʻohe. Loaʻa i nā 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 uila i ka uea. Hoʻokiʻoki ka mīkini hana i ka uwea ma ka hoʻokuʻu ʻana i ke kahua magnetic e wili. ʻO ke kahua magnetic rotating ka rotor a ʻo ka uea i ʻoki ʻia ʻo ia ka stator.
