ʻokoʻa hana kaʻa kaʻa 1: ka wikiwiki/torque/nui
Aia nā ʻano kaʻa like ʻole ma ka honua.ʻO ke kaʻa nui a me ka mīkini liʻiliʻi.He kaʻa e neʻe ana i hope a i mua ma mua o ka hoʻololi ʻana.ʻO kahi kaʻa kaʻa i ka nānā mua ʻana ʻaʻole maopopo ke kumu o ka pipiʻi.Eia nō naʻe, koho ʻia nā motika āpau no ke kumu.No laila he aha ke ʻano kaʻa, hana a i ʻole nā hiʻohiʻona e pono ai i kāu kaʻa kūpono?
ʻO ke kumu o kēia moʻo ka hāʻawi ʻana i ka ʻike e pili ana i ke koho ʻana i ka motika kūpono.Manaʻo mākou e pono ke koho ʻoe i kahi kaʻa.A, manaʻolana mākou e kōkua ia i ka poʻe e aʻo i nā kumu o nā kaʻa.
E māhele ʻia nā ʻokoʻa hana e wehewehe ʻia i ʻelua mau ʻāpana e like me kēia:
Speed/Torque/Size/Price ← ʻO nā mea a mākou e kūkākūkā ai ma kēia mokuna
ʻO ka pololei ka wikiwiki / ka maʻalahi / ke ola a me ka mālamaʻana / ka hana lepo / ka maikaʻi / ka wela
Hoʻoulu mana / haʻalulu a me ka walaʻau / hoʻopau hoʻopau / hoʻohana i ke kaiapuni
1. Nā manaʻolana no ke kaʻa: ka neʻe ʻana
ʻO ka motika ka mea maʻamau i kahi kaʻa e loaʻa ai ka ikehu mechanical mai ka ikehu uila, a i ka nui o nā hihia e pili ana i kahi kaʻa e loaʻa ai ka neʻe kaʻa.(Aia kekahi kaʻa laina laina e holo pololei, akā e haʻalele mākou i kēia manawa.)
No laila, he aha ke ʻano o ka huli ʻana āu e makemake ai?Makemake ʻoe e milo ikaika ʻo ia e like me ka drill, a i ʻole makemake ʻoe e milo nāwaliwali me ka wikiwiki nui e like me ka peʻahi uila?Ma ka nānā ʻana i ka ʻokoʻa o ka neʻe ʻana o ka rotational i makemake ʻia, lilo nā waiwai ʻelua o ka wikiwiki a me ka torque i mea nui.
2. Torque
ʻO Torque ka ikaika o ka hoʻololi.ʻO ka ʻāpana o ka torque ʻo N·m, akā i ka hihia o nā kaʻa liʻiliʻi, hoʻohana mau ʻia ka mN·m.
Ua hoʻolālā ʻia ka motika ma nā ʻano like ʻole e hoʻonui ai i ka torque.ʻOi aku ka nui o ka huli ʻana o ka uea electromagnetic, ʻoi aku ka nui o ka torque.
No ka mea ua kaupalena ʻia ka helu o ka wili e ka nui o ka coil paʻa, ua hoʻohana ʻia ka uea enamelled me kahi anawaena uea nui aʻe.
ʻO kā mākou moʻo kaʻa brushless (TEC) me 16 mm, 20 mm a me 22 mm a me 24 mm, 28 mm, 36 mm, 42 mm, nā ʻano 8 o 60 mm ka nui o waho.Ma muli o ka piʻi ʻana o ka nui o ka coil me ke anawaena kaʻa, hiki ke loaʻa ke kiʻekiʻe kiʻekiʻe.
Hoʻohana ʻia nā magnet ikaika e hana i nā torques nui me ka ʻole e hoʻololi i ka nui o ka mīkini.ʻO nā magnet neodymium ka mea ikaika loa, a ukali ʻia e nā magnet samarium-cobalt.Eia nō naʻe, inā ʻoe e hoʻohana wale i nā magnet ikaika, e kahe ka mana magnetic i waho o ke kaʻa, a ʻaʻole e hāʻawi ka ikaika magnetic leaking i ka torque.
No ka hoʻohana piha ʻana i ka magnetism ikaika, ua laminated ʻia kahi mea hana lahilahi i kapa ʻia ʻo electromagnetic steel plate e hoʻomaikaʻi i ke kaapuni magnetic.
Eia kekahi, no ka paʻa ʻana o ka ikaika magnetic o ka samarium cobalt magnets i nā hoʻololi wela, hiki i ka hoʻohana ʻana i nā magnet samarium cobalt hiki ke hoʻokele paʻa i ka kaʻa i loko o kahi kaiapuni me nā loli wela nui a i ʻole nā wela kiʻekiʻe.
3. Ka māmā holo
ʻO ka helu o nā kipi o kahi kaʻa i kapa pinepine ʻia ʻo "wikiwiki".ʻO ia ka hana ʻana i ka nui o ka manawa o ka holo ʻana o ke kaʻa i kēlā me kēia manawa.ʻOiai ua hoʻohana mau ʻia ka "rpm" ma ke ʻano he hoʻololi i kēlā me kēia minuke, ua hōʻike pū ʻia ʻo ia ʻo "min-1" ma ka ʻōnaehana SI o nā ʻāpana.
Ke hoʻohālikelike ʻia me ka torque, ʻaʻole paʻakikī ka hoʻonui ʻana i ka nui o nā kipi.E ho'ēmi wale i ka helu o nā huli i ka wili e hoʻonui i ka helu o nā huli.Eia nō naʻe, no ka emi ʻana o ka torque i ka piʻi ʻana o ka nui o nā kipi, he mea nui ia e hoʻokō i nā koi ʻelua a me ke kipi.
Eia kekahi, inā hoʻohana ka wikiwiki kiʻekiʻe, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā bearings ma mua o nā bearings maʻamau.ʻO ke kiʻekiʻe o ka wikiwiki, ʻoi aku ka nui o ka nalowale o ka friction, ʻoi aku ka pōkole o ke ola o ke kaʻa.
Ma muli o ka pololei o ke kumu, ʻoi aku ka kiʻekiʻe o ka wikiwiki, ʻoi aku ka nui o ka walaʻau a me nā pilikia pili i ka vibration.No ka mea, ʻaʻohe pulupulu a i ʻole commutator ka mīkini palaki ʻole, hoʻemi ʻo ia i ka walaʻau a me ka haʻalulu ma mua o ke kaʻa palaki (e hoʻopili ana i ka pulupulu me ka commutator huli).
KaʻAnuʻu 3: Nui
I ka hiki ʻana i ka mīkini kūpono, ʻo ka nui o ka mīkini kekahi o nā mea nui o ka hana.ʻOiai inā lawa ka wikiwiki (revolutions) a me ka torque, he mea ʻole inā ʻaʻole hiki ke hoʻokomo ʻia ma ka huahana hope.
Inā makemake wale ʻoe e hoʻonui i ka wikiwiki, hiki iā ʻoe ke hoʻemi i ka helu o ka huli ʻana o ka uea, ʻoiai inā he liʻiliʻi ka helu o nā huli, akā inā ʻaʻole he torque liʻiliʻi, ʻaʻole ia e hoʻololi.No laila, pono e ʻimi i nā ala e hoʻonui ai i ka torque.
Ma waho aʻe o ka hoʻohana ʻana i nā magnet ikaika i luna, he mea nui hoʻi e hoʻonui i ke kumu o ke kaʻina hana o ka wili.Ua kamaʻilio mākou e pili ana i ka hoʻemi ʻana i ka helu o ka wili uea e hōʻoia i ka nui o nā kipi, akā ʻaʻole kēia manaʻo ua ʻeha ʻia ka uea.
Ma ka hoʻohana ʻana i nā uea mānoanoa ma mua o ka hoʻemi ʻana i ka helu o nā wiliwili, hiki ke kahe ka nui o ke au a hiki ke loaʻa ka torque kiʻekiʻe ma ka wikiwiki like.ʻO ka coefficient spatial kahi hōʻailona o ka paʻa o ka ʻeha o ka uea.Ke hoʻonui nei i ka helu o nā huli lahilahi a i ʻole e hōʻemi ana i ka helu o nā huli mānoanoa, he mea nui ia i ka loaʻa ʻana o ka torque.
Ma keʻano laulā, pili ka hopena o kahi kaʻa ma nā kumu ʻelua: hao (magnet) a me ke keleawe (winding).
