ʻO ka motika Brushless: he aha kāu e ʻike ai e pili ana i kēia mau motika

Mīkini palaki ʻole

Ua lohe paha ʻoe i ka kaʻa palaki. He mea maʻamau ke ʻike i kēia huaʻōlelo i nā wehewehe huahana. ʻO kahi laʻana, ma drones hiki iā ʻoe ke ʻike he nui ka poʻe i loaʻa kēia ʻano mīkini uila. ʻO ka ʻoiaʻiʻo, hoʻohana kekahi mau mea hana iā ia ma ke ʻano he koi no nā mea kūʻai aku, no ka mea, he loaʻa kā lākou keu.

Akā he aha kēia kaʻa palaki? He aha nā mea ʻokoʻa ma laila e pili ana i nā ʻano ʻē aʻe o DC motors. ʻO kēlā mau mea āpau kānalua aʻoi aku nā mea hou e hoʻāʻo wau e wehewehe iā lākou i kēia ʻatikala ...

E like me nā ʻano ʻē aʻe o Nā mea uila, hiki ke hoʻohui maikaʻiʻia kēia mau mīkini me kāu mau papahana DIY me ka papa arduino me nā mea ʻē aʻe

He aha ka motika palaki?

Un motika palaki, a ʻaʻohe motika palaki, He mīkini uila maʻamau a me kēia manawa, akā ʻaʻole ia e hoʻohana i nā palaki e hoʻololi i ka polarity o ka motoka. Hōʻalo kēia i kekahi mau pilikia ʻenehana a pale iā lākou mai ka hoʻololi ʻia ʻana. ʻO ia ke kumu e hoʻohana ʻia ai ma ke ʻano he koi, ʻoiai he ʻoiaʻiʻo he kuleana kānalua ia, ʻoiai ʻo ka hapa nui o nā motuka i kēia manawa ʻaʻole palaki.

ka uila uila ʻAe, loaʻa iā lākou kēia ʻano brushes, kekahi mau mea e ʻānai a no laila e hoʻoliʻiliʻi i ka hana o ka motika e ka friction, e hoʻonui i ka mahana, kaʻae, halulu, a koi i kēia mālama e hoʻomaʻemaʻe i ka lepo kalapona i hana ʻia i loko o ka motika (kahi ʻaʻole hiki ke keʻakeʻa wale i ka hana, hiki ke alakaʻi a alakaʻi i nā pilikia uila) a hoʻololi i nā kāhili luhi.

ʻO ia ke kumu i hoʻomohala ʻia ai nā motika palaki mua. Mua ma ke kula o nā mīkini AC asynchronous, a ma hope e hana ana i ka lele i nā motika ʻē aʻe e like me DC, ʻo ia ka mea hoihoi iā mākou i kēia blog.

ʻOiai ma mua he mea puke a ʻoi aku ka pipiʻi e hana, ka holomua o ka ʻenehana a me nā uila i hiki i kēia manawa ke hana i ka ʻoihana waiwai. Eia nō naʻe, hiki i kona kaohi ke lilo i mea paʻakikī. ʻOiai ua hoʻopau nā kaohi wikiwiki ʻo ESC i kēia mau pilikia ...

I kēia manawa, aia nā motika AC ma lehulehu o nā kime home a me nā ʻoihana, a me nā kaʻa, etc. No ka CC, hiki iā ʻoe ke loaʻa iā lākou i loko o ka poʻe heluhelu diski opua, nā mea pā kamepiula, nā drone, nā robots, a me kahi lōʻihi a pēlā aku.

ʻO nā ʻāpana o kahi motika brushless a me ka hana

ʻO kaʻoiaʻiʻoʻo ia nā ʻāpana He maʻalahi ka motika palaki. Me kahi stator me nā pale magnetika i wehewehe ʻia i loko o ka ʻatikala e pili ana i nā motika uila, a me kahi rotor e huli aʻe ma muli o ka impulse o ka māno mākala.

Akā ke ala e hana ai iā lākou ʻae he ʻokoʻa iki ia mai nā DC a me nā motika AC brushing. Eia nō naʻe, like nā kumu hana a me nā hiʻohiʻona he nui.

E maʻalahi ai nā mea, ka ESC (Electronic Speed ​​Controller), ʻo ia hoʻi, nā mea hoʻokele e hiki ai ke hoʻololi i ka polarity o nā wili ʻana o kahi motika brusheless e kāohi ai i ke kaʻapuni. ʻAe lākou i ka maʻalahi maʻalahi e PWM, me nā microcontrollers e like me ka mea ma ka papa Arduino.

Loaʻa i nā modula ESC nā mea uila i hiki ke hana ma ka motika me ka ʻole o ka hoʻopilikia nui ʻana i ka mea hoʻohana. Kaukaʻi ʻia i ke ʻano o ka ʻenekini a me ka mana āu e pono ai i kahi ʻano a i ʻole o kekahi O Keaukaha, e like me kā mākou i loiloi ai i nā ʻatikala ʻē aʻe.

E hoʻomanaʻo hiki iā ʻoe ke hoʻohana Nā transistors MOSFET e mālama iā ia inā ʻaʻohe ou module o kēia. ʻO ke kumu he mea hoʻokele a ESC paha kahi kaʻapuni e hiki ai ke hoʻololi i ka polarity o nā transistors e hoʻololi i ka polarity lako mana o ka motika mahalo i nā transistors nāna e haku.

Nā pōmaikaʻi

Entre nā mea maikaʻi o kahi kīkaha kīnā ʻole nui:

  • Lāki hiʻohiʻona ʻoi aku ka wikiwiki a me ka lakio. No laila, hiki iā ʻoe ke unuhi i ka hana hou mai iā lākou.
  • ʻO ka pane hōʻeuʻeu maikaʻi aʻe.
  • ʻOi aku ka maikaʻi o ka ikehu, e mālama i ka ikehu. ʻO ka mea nui i nā hāmeʻa uila uila.
  • ʻOi aku ka wela. ʻAʻole pono nā ʻōnaehana hoʻopau hou a i ʻole nā ​​lole nui.
  • ʻOi aku ke kūpaʻa, no ka mea ʻaʻole pono ka mālama nui ʻana, ʻaʻohe ona wī a ʻaʻahu paha.
  • Walaʻau liʻiliʻi. Noho mālie lākou ma ka hoʻopā ʻole ʻana i kekahi mea.
  • ʻO ka wikiwiki kiʻekiʻe, kūpono no nā noi kahi e pili ai, e like me nā drones heihei.
  • Kūpono I loko nō o ka ikehu i loaʻa iā lākou, ʻoi aku ka nui o nā mea āpau āpau i like me ka motika brushing.
  • Me ka mālama ʻole. ʻAʻole ʻoe e kū pono ʻole ma muli o ke kau ʻana o nā palaki, ʻaʻole hoʻi ʻoe e kūʻai i nā ʻāpana keu, hoʻomaʻemaʻe i ka lepo i hana ʻia, etc.

drawbacks

ʻOiaʻiʻo, ʻaʻole maikaʻi nā motika palaki i nā mea āpau. Loaʻa iā lākou kā lākou poʻe liʻiliʻi nā meaʻino:

  • ʻO ke kumukūʻai, ʻoi aku kona kiʻekiʻe ma mua o nā motika palaki. Eia nō naʻe, ke ʻano ʻenehana i kēia manawa hiki iā ʻoe ke kūʻai i kahi motika palaki ma nā kumukūʻai maikaʻi.
  • No ka kaohi ʻana iā ʻoe e pono ʻoe i nā mea kalaiwa a i ʻole nā ​​mea hoʻokele i hiki iā ʻoe ke kaohi i ka hoʻohuli. ʻAʻole hiki ke hana me ka lima e like me nā hihia ʻē aʻe.

ʻOiai kēlā, ʻo lākou nā meaua kau ʻia ma ka ʻoihana a he mea kūpono ke koho ʻana i kekahi o lākou ...

Ma hea e kūʻai ai i kahi motika palaki?

kaʻa palaki

ʻO ka mea hope loa, inā makemake ʻoe e kūʻai i kaʻa kaʻa palaki e hoʻoponopono i kāu drone, a i ʻole no kāu papahana hana, hiki iā ʻoe ke loaʻa iā lākou i nā hale kūʻai kūikawā a i ʻole ma Amazon. ʻO kahi laʻana, eia kekahi huahana:


Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.

E lilo i mea mua e wehewehe

E waiho i kāu manaʻo

Kāu leka uila aae? E,ʻaʻole e paʻiʻia. i hāliu aku i koi 'ia kula *
