ʻO ke kuleana o nā pulupulu kalapona i nā motika drill hopena

ʻO ke kuleana o ka palaki carbon drill hopena ʻo ia ka hoʻouna ʻana i ka manawa hoʻohiwahiwa i hana ʻia e ka mea hoʻohiwahiwa hoʻoulu i ka ʻōnaʻi rotor. ʻO ke kumumanaʻo o ka hopena wili uila ma hope o ka ʻoki ʻia ke kahua magnetic i ka uea, hana ʻia ke au i ka uea. ʻO ka generator hoʻohana i ke ʻano o ka hoʻololi ʻana i ke kahua magnetic e ʻoki ai i ka uea. ʻO ka hoʻololi ʻana ʻO ke kahua magnetic ka rotor, a ʻo ka uea ʻoki ʻia ka stator. No ka rotor no ka hoʻoulu ʻana i kahi māla magnetic, pono e hoʻokomo ʻia kahi au hoʻouluulu i ka wili o ka rotor, a ʻo ka pulupulu kalapona ke hana i kēia kuleana.

ʻOiaʻiʻo, ʻo ka "brush" ma aneʻi e pili ana i nā pulupulu kalapona. Hoʻohana maʻamau nā ʻōkuhi hopena i nā motika DC. ʻO nā hoʻomaʻamaʻa hoʻopalekana palaki e hoʻohana i nā kaʻa kaʻa palaki, pono e hoʻololi ʻia ma o nā pulupulu. ʻO ke kalapona Hoʻololi ʻia ka pulupulu e kahi mea ʻike Hall a alakaʻi ʻia e ka mea hoʻokele e hoʻololi.

Ke hoʻohālikelike ʻia me nā drills impact brushless, loaʻa ka nui o nā drills impact brushed nā pono a me nā pōʻino:

Advantages: The brushed impact drill starts quickly, brakes timely, smooth speed regulation, simple control, simple structure, cheap price, and it has a large starting current, large torque (rotation force) at low speed, and can carry a heavy load.

Nā pōʻino: Ma muli o ka hakakā ma waena ʻO ka pulupulu kalapona a me ka commutator, ʻoi aku ka maʻalahi o ka drill hopena me kahi pulupulu nā huna ahi, ka wela, ka walaʻau, ka hoʻopili electromagnetic i ke kaiapuni o waho, a me ka hana haʻahaʻa a me ke ola pōkole; ʻO nā pulupulu kalapona nā mea hoʻohana, ma hope o kekahi manawa o ka manawa, e pani ia, he pilikia.
