Differences and Application Scenarios between Carbon Brush DC Motors and Brush DC Motors

Mu gawo la uinjiniya wamagetsi, ma motors a Direct current (DC) amagwira ntchito yofunika kwambiri pamagwiritsidwe osiyanasiyana. Pakati pa ma mota a DC, omwe ali ndi maburashi amagwiritsidwa ntchito kwambiri. Komabe, zikuwoneka kuti pali chisokonezo chokhudza ma mota a carbon brush DC ndi ma brush DC motors. M'nkhaniyi, tikambirana kusiyana pakati pawo ndikuwunika momwe amagwiritsira ntchito.

Kufotokozera Terminology

Choyamba, ndikofunikira kudziwa kuti ma motor brashi a DC ndi kagawo kakang'ono ka maburashi a DC. Mawu oti "brush DC motor" ndi gulu lodziwika bwino, pomwe "carbon brush DC motor" amatanthauza maburashi a DC motor pomwe maburashi amapangidwa makamaka ndi zida zopangira kaboni.

Kusiyana Kwamapangidwe ndi Zida

Burashi Zofunika

Carbon Brush DC Motors: Monga dzina limatanthawuzira, maburashi omwe ali m'ma injiniwa amakhala opangidwa ndi kaboni. Mpweya uli ndi zinthu zabwino kwambiri zodzipaka mafuta, zomwe zimachepetsa kukangana pakati pa burashi ndi commutator. Izi zimapangitsa kuti maburashi azikhala ochepa komanso kuti asawonongeke, zomwe zimapangitsa kuti moyo ukhale wautali. Kuonjezera apo, carbon ndi yabwino kondakitala magetsi, ngakhale madutsidwe ake si mkulu monga zitsulo zina. Mwachitsanzo, m'ma motors ang'onoang'ono a hobbyist, maburashi a kaboni amagwiritsidwa ntchito nthawi zambiri chifukwa cha mtengo wawo - wogwira mtima komanso wodalirika.

Brush DC Motors (mwanjira zambiri): Maburashi mu non - carbon - brush DC motors amatha kupangidwa kuchokera ku zipangizo zosiyanasiyana. Maburashi a Metal - graphite, mwachitsanzo, amaphatikiza kuwongolera kwamagetsi kwazitsulo (monga mkuwa) ndi kudzipaka mafuta ndi kuvala - kugonjetsedwa ndi graphite. Maburashi awa nthawi zambiri amagwiritsidwa ntchito ngati maburashi omwe amanyamula kuchuluka kwamakono.

Kuyanjana kwa Commutator

Carbon Brush DC Motors: Maburashi a kaboni amayenda bwino pamwamba pa commutator. Kudzitchinjiriza kwa carbon kumathandizira kuti pakhale mphamvu yolumikizana, yomwe ndiyofunikira kuti magetsi azitha kulumikizidwa. Nthawi zina, maburashi a kaboni amathanso kutulutsa phokoso lochepa lamagetsi panthawi yogwira ntchito, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zomwe zimakhudzidwa ndi kusokonezedwa ndi ma elekitiroma.

Brush DC Motors Ndi Maburashi Osiyanasiyana: Maburashi a Metal - graphite, chifukwa cha mawonekedwe awo osiyanasiyana, angafunike mawonekedwe osiyanasiyana a commutator. Kuthamanga kwapamwamba kwa gawo lachitsulo kungayambitse zosiyana zamakono - zogawanitsa pamtunda wa commutator, motero, commutator ingafunike kupangidwira kuti izigwira bwino kwambiri.

Kusiyana kwa Kachitidwe

Mphamvu ndi Mwachangu

Carbon Brush DC Motors: Nthawi zambiri, ma mota a carbon brush DC ndi oyenerera kugwiritsa ntchito mphamvu zochepa - mpaka - zapakati. Madutsidwe awo ocheperako poyerekeza ndi maburashi achitsulo - amatha kukhala okwera pang'ono kukana magetsi, zomwe zingayambitse kutayika kwa mphamvu mu mawonekedwe a kutentha. Komabe, katundu wawo wodzitchinjiriza amachepetsa kuwonongeka kwamakina chifukwa cha kukangana, komwe kumathandizira kuti ntchitoyo ikhale yabwino. Mwachitsanzo, m'zida zazing'ono zapakhomo monga mafani amagetsi, ma motor brashi a DC amagwiritsidwa ntchito nthawi zambiri, kupereka mphamvu zokwanira pomwe amakhalabe ndi mphamvu - zogwira ntchito zapakhomo.

Brush DC Motors Ndi Maburashi Osiyanasiyana: Ma mota okhala ndi zitsulo - maburashi a graphite nthawi zambiri amagwiritsidwa ntchito pamagetsi apamwamba. Kuthamanga kwamagetsi kwa chigawo chachitsulo kumapangitsa kuti pakhale kusamutsidwa kwachangu kwazinthu zambiri zamakono, zomwe zimapangitsa kuti pakhale mphamvu zambiri. Makina akumafakitale, monga makina akulu onyamula katundu, nthawi zambiri amagwiritsa ntchito ma mota amtunduwu poyendetsa katundu wolemetsa.

Kuthamanga Kwambiri

Carbon Brush DC Motors: Kuwongolera liwiro la carbon brush DC motors zitha kutheka kudzera m'njira zosiyanasiyana, monga kusintha magetsi olowera. Komabe, chifukwa cha chibadwa chawo, iwo sangapereke mulingo wofanana wa kuwongolera liwiro ngati mitundu ina ya ma mota. M'mapulogalamu omwe kukhazikika kwa liwiro sikofunikira kwambiri, monga mafani ena osavuta a mpweya wabwino, ma mota a carbon brush DC amatha kugwira ntchito mokwanira.

Brush DC Motors Ndi Maburashi Osiyanasiyana: Nthawi zina, makamaka ndi zida zotsogola zamaburashi ndi mapangidwe, kuwongolera liwiro kumatha kukwaniritsidwa. Kutha kuthana ndi mafunde apamwamba komanso kulumikizidwa kwamagetsi kokhazikika kumatha kupangitsa njira zowongolera kwambiri - zowongolera, monga kugwiritsa ntchito pulse - wide modulation (PWM) bwino. Ma servo motors omwe amagwira ntchito kwambiri, omwe amafunikira kuwongolera mwachangu pamagwiritsidwe ntchito ngati maloboti, amatha kugwiritsa ntchito maburashi okhala ndi zida zapadera pazifukwa izi.

Zochitika za Ntchito

Carbon Brush DC Motors

Consumer Electronics: Amagwiritsidwa ntchito kwambiri pamagetsi ang'onoang'ono ogula monga maburashi amagetsi, zowumitsira tsitsi, ndi mafani onyamula. Kukula kwawo kophatikizana, mtengo wake wotsika, komanso magwiridwe antchito okwanira amakwaniritsa zofunikira za zidazi.

Zida Zagalimoto: M'magalimoto, ma motor brashi a DC amagwiritsidwa ntchito ngati ma wipers a windshield, mawindo amagetsi, ndi zosinthira mipando. Ma motors awa ayenera kukhala odalirika komanso okwera mtengo, ndipo ma mota a kaboni burashi a DC amakwanira ndalamazo.

Brush DC Motorsndi Maburashi Osiyanasiyana

Industrial Machinery: Monga tanena kale, m'mafakitale, ma motors okhala ndi maburashi apamwamba amagwiritsidwa ntchito poyendetsa zida zazikulu. Pafakitale yopangira, ma motors opangira mphamvu zazikulu - mapampu amphamvu, ma compressor, ndi makina amphero nthawi zambiri amafuna kutulutsa mphamvu kwamphamvu komanso kuwongolera kolondola, komwe kumatha kuperekedwa ndi maburashi a DC okhala ndi zida zoyenera za burashi.

Zamlengalenga ndi Chitetezo: Pazinthu zina zakuthambo, monga zoyendetsa ndege, ma motors a DC okhala ndi maburashi apadera amagwiritsidwa ntchito. Ma motors awa amafunika kugwira ntchito pansi pazovuta kwambiri, kuphatikiza kutentha kwambiri komanso malo ogwedezeka kwambiri. Kusankha zinthu zabrashi ndikofunikira kuti zitsimikizire kuti zikuyenda bwino muzochitika zovuta zotere.

Pomaliza, pomwe ma mota a kaboni burashi a DC ndi mtundu wa mota ya DC burashi, kusiyana kwa zida za burashi ndi zotsatira zake zogwirira ntchito kumabweretsa mawonekedwe osiyanasiyana ogwiritsira ntchito. Kumvetsetsa kusiyana kumeneku ndikofunikira kwa mainjiniya ndi opanga posankha mota yoyenera kwambiri ya DC pakugwiritsa ntchito.
