20V Lithium pākahi cordless drill

ʻO ka ʻokoʻa nui ma waena o ka mīkini pahu lithium a me ka mīkini brushless aia i kā lākou hana ʻana a me ka hana.

Kaʻa Pahu: Hoʻohana pinepine ʻia nā ʻenekini lithium kuʻuna i nā ʻenekini palaki. Loaʻa i kēia mau kaʻa nā pulupulu kalapona e hāʻawi i ka mana i ka commutator, a ʻo ia ka mea e wili ai i ka armature o ka kaʻa. I ka wili ʻana o ka kaʻa, hoʻopili kino nā pulupulu me ka commutator, e hana ana i ka friction a me ka wela. ʻO kēia friction a ʻaʻahu i nā pulupulu a me ka commutator hiki ke alakaʻi i ka hoʻemi ʻana i ka pono a me ke ola o ka manawa.

ʻAʻole hoʻohana nā kaʻa Brushless: ʻO nā motika Brushless, ma kekahi ʻaoʻao, mai hoʻohana i nā pulupulu a i ʻole commutator no ka hāʻawi ʻana i ka mana. Akā, hilinaʻi lākou i nā mea hoʻokele uila e hoʻomalu pono i ke kahe o ka uila i nā wili kaʻa. Hoʻopau kēia hoʻolālā i ka pono o nā pulupulu, e hōʻemi ana i ka friction a me ka lole. ʻO ka hopena, ʻoi aku ka maikaʻi o nā mīkini brushless, ʻoi aku ka lōʻihi o ke ola ʻana, a ʻoi aku ka mālie i ka hoʻohālikelike ʻia me nā kaʻa brushed. Hāʻawi pū lākou i ka mana hou aʻe no ka nui like a me ke kaumaha, e hoʻonui ai iā lākou i nā mea hana mana e like me nā drills.

I ka hōʻuluʻulu ʻana, ʻoiai hiki i nā ʻano kaʻa ʻelua ke mana i kahi drill lithium, hāʻawi nā mīkini brushless i nā pono i ka pono, ke ola, a me ka hana. Eia nō naʻe, hiki mai lākou i ke kumu kūʻai kiʻekiʻe aʻe i hoʻohālikelike ʻia i nā drills me nā mīkini palaki.

ʻO ka mīkini pahu pahu lithium e pili ana i ke ʻano o ka mīkini i hoʻohana ʻia i nā mea hana mana e like me nā drills a me nā mea hoʻopili palaki. ʻO ka Lithium e pili ana i ke ʻano o ka pākaukau e hoʻohana ana i ka drill, ʻoiai ʻo ka motika ponoʻī he mīkini DC brushed a brushless paha.

Loaʻa i nā motika palaki nā pulu kalapona e hāʻawi i ke au uila i ka armature kaʻa, ʻoiai nā kaʻa brushless e hoʻohana i nā mea hoʻokele uila e hāʻawi i ka mana i nā wili. ʻOi aku ka maikaʻi a me ka lōʻihi o nā motika brushless ma mua o nā kaʻa brushed, akā ʻoi aku ka nui o ke kumukūʻai.

Hoʻohana maʻamau ʻia nā pākahi Lithium-ion i nā mea hana mana ma muli o ko lākou kiʻekiʻe kiʻekiʻe o ka ikehu a me ke ʻano rechargeable, e hāʻawi ana i nā manawa holo lōʻihi i hoʻohālikelike ʻia me nā ʻano pākaukau ʻē aʻe. Ke hui pū ʻia me kahi kaʻa brushless, hiki i nā drills lithium-ion-powered ke hāʻawi i ka hana kiʻekiʻe a me ke ola mea hana lōʻihi.
