Kodi pali kusiyana kotani pakati pa motor brushed ndi brushless motor?

Ma motors opanda maburashi ndi maburashi ali ndi cholinga chomwecho chosinthira magetsi kukhala oyenda mozungulira.

Ma motors opukutidwa akhalapo kwa zaka zopitilira zana, pomwe ma motors opanda brush adatuluka muzaka za m'ma 1960 ndikupangidwa kwamagetsi olimba omwe adathandizira kupanga kwawo. Komabe, sizinali mpaka zaka za m'ma 1980 pomwe ma motors opanda brush adayamba kuvomerezedwa kwambiri ndi zida zosiyanasiyana ndi zamagetsi. Masiku ano, maburashi ndi ma brushless motors amagwiritsidwa ntchito padziko lonse lapansi pazinthu zambiri.

Kuyerekeza Kwamakina

Makina opukutiraimagwira ntchito pogwiritsa ntchito maburashi a kaboni polumikizana ndi commutator kusamutsa voteji yamagetsi kupita ku rotor, yomwe ili ndi ma elekitiroma. Mphamvu yamagetsi imapanga gawo lamagetsi lamagetsi mu rotor, zomwe zimapangitsa kuti pakhale kusuntha kozungulira chifukwa chosinthasintha mosalekeza polarity ya kukoka kwa maginito.

Komabe, mapangidwe ake ndi osavuta, koma pali zovuta zina:

1. Moyo wocheperako: Ma motors opukutidwa amakhala ndi moyo waufupi chifukwa cha kung'ambika kwa maburashi ndi ma commutator.

2 Kuchita bwino pang'ono: Ma motors opukutidwa ali ndi mphamvu zochepa poyerekeza ndi ma brushless motors. Maburashi ndi ma commutator amayambitsa kutha kwa mphamvu komanso kutayika kwamagetsi, zomwe zimapangitsa kuti kutentha kumachulukane.

3. Kuchepetsa liwiro: Chifukwa cha kapangidwe ka maburashi ndi ma commutators, maburashi amoto amakhala ndi malire pakugwiritsa ntchito kuthamanga kwambiri. Kukangana pakati pa maburashi ndi ma commutator kumalepheretsa kuthamanga kwambiri kwa ma motors opukutidwa, ndikuchepetsa kugwiritsa ntchito kwawo ndi magwiridwe antchito ena.

Galimoto yopanda brush ndi amagetsi kugwedera galimotozomwe zimagwira ntchito popanda kugwiritsa ntchito maburashi ndi commutator. M'malo mwake, zimadalira olamulira amagetsi ndi masensa kuti aziwongolera mphamvu zomwe zimatumizidwa ku ma windings a injini mwachindunji.

Pali zovuta zingapo pakupanga brushless:

1. Mtengo wapamwamba: Ma motors opanda brush nthawi zambiri amakhala okwera mtengo kuposa ma brushed motors chifukwa cha mapangidwe awo ovuta kwambiri ndi machitidwe awo olamulira.

2. Zovuta zamagetsi: Ma motors opanda maburashi amaphatikizapo machitidwe ovuta olamulira amagetsi omwe amafunikira chidziwitso chapadera pakukonza ndi kukonza.

3. Ma torque ochepa pa liwiro lotsika: Ma motors opanda maburashi amatha kukhala ndi torque yotsika poyerekeza ndi ma motors opukutidwa. Izi zitha kuchepetsa kuyenerera kwawo pazinthu zina zomwe zimafuna torque yayikulu pa liwiro lotsika.

Chabwino n'chiti: Chotsuka kapena Burashi?

Mapangidwe onse a ma brushed ndi brushless motor ali ndi maubwino awo.Ma motors opukutidwa ndi zotsika mtengo chifukwa cha kuchuluka kwawo.

Kuphatikiza pa mtengo, ma motors a brushed ali ndi zabwino zawo zomwe ziyenera kuganiziridwa:

1. Kuphweka: Ma motors opukutidwa ali ndi mapangidwe osavuta, kuwapangitsa kukhala osavuta kumvetsetsa ndikugwira nawo ntchito. Kuphweka kumeneku kungathandizenso kuti zikhale zosavuta kuzikonza ngati pali vuto lililonse.

2. Kupezeka kwakukulu: Ma motors a brushed akhalapo kwa nthawi yaitali ndipo amapezeka kwambiri pamsika. Izi zikutanthawuza kuti kupeza zolowa m'malo kapena zopangira zokonzera nthawi zambiri kumakhala kosavuta.

3. Kuwongolera kosavuta: Ma motors opukutidwa ali ndi njira yosavuta yowongolera yomwe imalola kuwongolera kosavuta. Kusintha mphamvu yamagetsi kapena kugwiritsa ntchito magetsi osavuta kumatha kuwongolera liwiro la mota.

Ngati pakufunika kuwongolera kwakukulu, a brushless mota ikhoza kukhala chisankho chabwino kwambiri pakugwiritsa ntchito kwanu.

Ubwino wa brushless ndi:

1. Kuchita bwino kwambiri: Ma motors opanda maburashi alibe ma commutators omwe angayambitse kukangana ndi kutaya mphamvu, zomwe zimapangitsa kuti mphamvu zisinthe komanso kutentha pang'ono kuwonongeke.

2. Kutalika kwa moyo: Popeza ma motors a Brushless alibe maburashi omwe amawonongeka pakapita nthawi kuti awonjezere kulimba komanso moyo wautali.

3. Chiŵerengero chapamwamba cha mphamvu ndi kulemera: Ma motors opanda brushless ali ndi chiŵerengero chapamwamba cha mphamvu ndi kulemera. Zikutanthauza kuti akhoza kupereka mphamvu zambiri chifukwa cha kukula ndi kulemera kwawo.

4. Kuchita modekha: Ma motors opanda maburashi satulutsa kuchuluka kwa phokoso lamagetsi ndi kugwedezeka kwamakina. Izi zimawapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimafunikira phokoso lochepa, monga zida zamankhwala kapena zida zojambulira.
