He aha nā mea maikaʻi o nā mīkini brushless?
Loaʻa i nā kaʻa Brushless nā mea maikaʻi ma mua o nā kaʻa brushed, me ka ʻoi aku ka maikaʻi, ka haʻahaʻa electromagnetic interference, a me ke ola lōʻihi. ʻOi aku ka liʻiliʻi a ʻoi aku ka māmā o nā moto brushless ma mua o nā moto brushed.
He aha nā hemahema o nā kaʻa kaʻa ʻole?
ʻO kekahi o nā hemahema nui o nā motika brushless ʻoi aku ka maikaʻi ma mua o nā mīkini brushed. Pono nō hoʻi nā motika Brushless i nā mea hoʻoponopono uila paʻakikī, e ʻoi aku ka nui o ke kumukūʻai.
ʻO nā mea paʻakikī o nā kaʻa Brushless: kahi nānā kokoke
ʻO nā motika Brushless kahi ʻano kaʻa uila e hoʻohana ana i nā māla magnetic e hoʻoulu i ka neʻe ʻana. ʻO nā mea nui ʻelua o ka mīkini brushless ka stator a me ka rotor. ʻO ka stator kahi mea paʻa i loaʻa i ka wili o ka kaʻa, ʻoiai ʻo ka rotor ka mea wili i loaʻa nā magnet mau loa. ʻO ka pilina ma waena o kēia mau mea ʻelua e hana i ka neʻe ʻana o ka mīkini.
ʻO ke kuleana o nā mea ʻike i nā kaʻa ʻole Brushless
Ke hilinaʻi nei nā motika Brushless i nā mea ʻike e hoʻoholo ai i ke kūlana o ka rotor a e hoʻololi i ke kaʻa. ʻO nā ʻano mea ʻike maʻamau i hoʻohana ʻia i nā kaʻa brushless ʻo ia nā mea ʻike hale, nā mea ʻike inductive, a me nā mea hoʻonā. Hāʻawi kēia mau mea ʻike i nā manaʻo i ka ʻōnaehana hoʻokele uila, e ʻae iā ia e hoʻoponopono i ka wikiwiki a me ke kuhikuhi o ka kaʻa e like me ka mea e pono ai.
Nā Pōmaikaʻi o nā Motor Brushless
Hāʻawi nā kaʻa Brushless i nā pono he nui ma mua o nā motika DC brushed kuʻuna, me:
- ʻOi aku ka maikaʻi
- ʻO ke ola lōʻihi
- ʻOi aku ke kiʻekiʻe o ka torque-to-weight ratio
- Pono mālama haʻahaʻa
- Hana mālie
Brushless Motors: Ma hea lākou i hoʻohana ʻia ai?
Hoʻohana maʻamau ʻia nā mīkini Brushless i nā hāmeʻa mana cordless ma muli o ko lākou kiʻekiʻe kiʻekiʻe a me nā pono mālama haʻahaʻa. ʻO kēia mau mea hana me nā wili, nā ʻili, a me nā hoʻokele hopena e koi ana i kahi kiʻekiʻe ikehu hoʻopuka a me ka hoʻomalu māmā māmā. Hiki i nā motika Brushless ke hāʻawi i kēia hoʻopuka me ka mālama ʻana i kahi liʻiliʻi liʻiliʻi a lōʻihi ke ola pākaukau i hoʻohālikelike ʻia me nā kaʻa brushed.
Uila uila
Hoʻohana pū ʻia nā motika Brushless i kekahi mau mea uila, e like me nā mea pā a me nā disk drive. ʻO ka haʻahaʻa haʻahaʻa a me ka wikiwiki pololei o nā kaʻa brushless e kūpono iā lākou no kēia mau noi. Eia kekahi, ʻo ka nele o nā pulupulu ʻo ia ka mea ʻaʻohe pono o ka mālama maʻamau, e hopena i ka lōʻihi o ke ola o ka hāmeʻa.
kaʻa hana
Ke hoʻomaka nei nā mīkini Brushless e hoʻomalu i ka ʻoihana automotive ma muli o ko lākou hiki ke hana me ka pololei a me ka mana. Hoʻohana pinepine ʻia lākou i nā kaʻa uila no ko lākou kiʻekiʻe kiʻekiʻe a me ka hiki ke mālama i kahi wikiwiki kikoʻī. Hoʻohui ʻia, ʻo ka nele o nā pulupulu ʻo ia ka mea ʻaʻohe pono o nā ʻāpana a i ʻole nā pili hou, e hopena i kahi hoʻolālā maʻalahi a hilinaʻi.
Pūnaehana Hoʻoluʻu kamepiula
Hoʻohana maʻamau ʻia nā motika Brushless i nā ʻōnaehana hoʻoluʻu kamepiula ma muli o ko lākou hiki ke mālama i ka wikiwiki a me ka hopena. ʻO ka hoʻolālā electromagnetic o nā motika brushless e hiki ai i ka pilina linear speed-torque, e hopena i ka hana maʻalahi a maikaʻi. Hoʻohui ʻia, ʻo ka liʻiliʻi liʻiliʻi o nā mīkini brushless e hiki ai i kahi ākea ākea o nā noi i nā ʻāpana kamepiula.
ʻOihana ʻenehana
Hoʻohana pū ʻia nā motika Brushless i ka ʻoihana aerospace no kā lākou mana kiʻekiʻe a me ka hiki ke mālama i kahi wikiwiki kikoʻī. Hoʻohana pinepine ʻia lākou i nā ʻōnaehana hoʻokele mokulele a me nā mea hoʻokele ma muli o ko lākou hilinaʻi a me ka pololei. Eia kekahi, ʻo ka nele o nā pulupulu ʻo ia ka mea ʻaʻohe pono o ka mālama maʻamau, e hopena i ka lōʻihi o ke ola o nā mea.
ʻO ka noiʻi a me ka hoʻomohala ʻana
Hoʻohana pū ʻia nā motika Brushless i ka noiʻi a me ka hoʻomohala ʻana no ko lākou hiki ke hāʻawi i kahi kiʻekiʻe o ka pololei a me ka mana. Hoʻohana pinepine ʻia lākou i ka hoʻāʻo ʻana i nā mea hana a me nā mea hana hale hana e koi ai i kahi wikiwiki a me ka hoʻopuka. Hoʻohui ʻia, ʻo ka nele o nā pulupulu ʻo ia ka mea ʻaʻohe pono o ka mālama mau ʻana, e hopena i ka lōʻihi o ke ola o nā mea hana.
Ke ʻimi ʻana i nā ʻenehana kūkulu ʻokoʻa o nā Motor Brushless
ʻO kekahi o nā ʻano maʻamau o nā kaʻa brushless ʻo ia ka mīkini magnet mau loa. I loko o kēia hana, ua hana ʻia ka rotor me nā magnet mau loa e hoʻopuni ana i ka armature uila. ʻO ka stator, ma ka ʻaoʻao ʻē aʻe, aia kekahi mau pou i ʻeha ʻia me nā wili. Ke hele ʻia ke au uila i loko o nā wili, hana ʻia kahi māla magnetic, e hoʻohuli ai ka rotor.
pono:
- High ka hoʻokōʻana
- ʻO ka mālama kūpono
- Ka mānoanoa mana kiʻekiʻe
- Pāheheheʻe ka hana
keakea:
- Uku i ka hana
- Paʻakikī ke kāohi i ka wikiwiki a me ke kūlana
- ʻAʻole kūpono no nā noi torque kiʻekiʻe
Nā Motors Reluctance Synchronous
ʻO kekahi ʻano o ka mīkini brushless ʻo ka synchronous reluctance motor. I loko o kēia kūkulu ʻana, aia ka rotor i nā pou ʻeha i hoʻopuni ʻia e nā magnet mau loa. ʻO ka stator, ma ka ʻaoʻao ʻē aʻe, aia nā pūʻulu o nā wili i ʻeha a puni nā pou. Ke hele ʻia ke au uila i loko o nā wili, hana ʻia kahi māla magnetic, e hoʻohuli ai ka rotor.

Brushless Vs Brushed DC Motors: He aha nā ʻokoʻa nui?
ʻOkoʻa nā motika DC brushless a brushed i kā lākou hoʻolālā a hana. ʻO nā motika DC Brushed he rotor, he stator, a he commutator, aʻo nā motika DC brushless he rotor me nā magnet mau a me kahi stator me nā wili. ʻO ka commutator i nā mīkini palaki ke kuleana no ka hoʻololi ʻana i ka polarity o ka electromagnet, ʻoiai i nā mīkini brushless, ua hoʻololi wale ʻia ka polarity o nā wili uila.
Nā ʻenehana hoʻomalu a me ka mana hoʻokomo
Pono nā ʻenekini palaki ʻole i nā ʻenehana hoʻomalu paʻakikī ma mua o nā kaʻa brushed. Pono lākou i ka volta komo kiʻekiʻe a me kēia manawa, a ʻo kā lākou mau kaʻa kaʻa kaʻa maʻamau i haku ʻia me ʻekolu pūʻulu o nā uea, ua hoʻonoho ʻia kēlā me kēia 120 degere. ʻO nā motika palaki, ma ka ʻaoʻao ʻē aʻe, koi wale i kahi uea hoʻokahi e hoʻololi ʻia no ka mālama ʻana i ke kahua magnetic rotating.
Hana a me ke ola
He ʻoi aku ka nui o ka mana-a-kaumaha ʻoi aku ka maikaʻi ma mua o nā kaʻa brushed. ʻOi aku ka lōʻihi o ko lākou ola ʻana ma muli o ka nele o nā pulupulu i pau i ka wā. Hiki i nā motika Brushless ke hāʻawi i ka hana maikaʻi a me ka ikaika o ka ikehu, e hoʻolilo iā lākou i koho maikaʻi loa no nā noi hana kiʻekiʻe.
ʻO ka walaʻau kani a me ka hoʻopili uila
Hoʻemi iki ka leo leo ʻole ma mua o nā kaʻa brushed ma muli o ka nele o nā pulu. Hoʻopuka pū lākou i ka liʻiliʻi electromagnetic interference, e hoʻolilo iā lākou i koho maikaʻi loa no nā noi e koi ai i ka leo haʻahaʻa a me ka liʻiliʻi o ka hoʻopili electromagnetic.
Ke koho ʻana ma waena o Brushless a Brushed DC Motors
I ke koho ʻana ma waena o nā motika DC brushless a brushed, aia kekahi mau kumu nui e noʻonoʻo ai:
- Pono ka mana o ka noi
- ʻO ka hana pono a me ka pono
- ʻO ka leo acoustic a me nā koi hoʻopilikia electromagnetic
- ʻO ke ola a me ka mālama pono
Ma muli o kēia mau mea, hiki i kekahi ke koho e hoʻohana i kahi kaʻa DC brushless a brushed paha. ʻOi aku ka maikaʻi o nā motika Brushless no nā noi hana kiʻekiʻe e koi ana i ka ʻoi aku ka maikaʻi o ka ikehu a me ka leo haʻahaʻa haʻahaʻa, ʻoiai ʻoi aku ka maikaʻi o nā kaʻa brushed no nā noi liʻiliʻi, haʻahaʻa haʻahaʻa e koi wale i kahi kaʻa kumu.

No laila, he ala maikaʻi loa nā motika brushless e loaʻa ai ka maikaʻi loa o kāu hāmeʻa me ka pilikia ʻole o ka hana ʻana i nā pulupulu. ʻOi aku ka maikaʻi, ʻoi aku ka mālie, a ʻoi aku ka lōʻihi o ke ola ma mua o nā kaʻa kaʻa. Eia kekahi, hoʻohana ʻia lākou i nā mea like ʻole he nui i kēia manawa, mai nā mea hana mana a i nā kaʻa uila. No laila, inā ʻoe e ʻimi nei i kahi kaʻa hou, pono ʻoe e noʻonoʻo i nā kaʻa brushless. ʻO lākou ka hope o nā kaʻa, ma hope o nā mea a pau. No laila, mai makaʻu e luʻu a hoʻāʻo iā lākou. ʻAʻole ʻoe e hoka!
