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

Mu uinjiniya wamagetsi, ma mota amagetsi olunjika (DC) amachita gawo lofunikira kwambiri pa ntchito zosiyanasiyana. Pakati pa ma mota a DC, omwe ali ndi maburashi amagwiritsidwa ntchito kwambiri. Komabe, zikuwoneka kuti pali chisokonezo chokhudza ma mota a DC a brush carbon ndi ma mota a DC a brush. M'nkhaniyi, tikambirana kusiyana pakati pawo ndikuwona momwe amagwiritsidwira ntchito.

Kufotokozera Mawu Ofunika

Choyamba, ndikofunikira kudziwa kuti ma mota a DC a brush brush kwenikweni ndi gawo la ma mota a DC a brush. Mawu akuti "brush DC motor" ndi gulu la anthu ambiri, pomwe "carbon brush DC motor" amatanthauza makamaka mota ya DC ya brush komwe ma mota amapangidwa makamaka ndi zinthu zopangidwa ndi kaboni.

Kusiyana kwa Kapangidwe ndi Zinthu

Burashi Yopangira Zinthu

Mpweya wa Burashi wa DC Motors: Monga momwe dzinalo likusonyezera, maburashi omwe ali mu ma mota awa amapangidwa kwambiri ndi kaboni. Mpweya wa kaboni uli ndi mphamvu zabwino kwambiri zodzipaka mafuta, zomwe zimachepetsa kukangana pakati pa burashi ndi commutator. Izi zimapangitsa kuti maburashi asamawonongeke kwambiri, zomwe zimapangitsa kuti nthawi ya moyo wawo ikhale yayitali. Kuphatikiza apo, kaboni ndi kondakitala wabwino wamagetsi, ngakhale kuti mphamvu yake si yayikulu ngati zitsulo zina. Mwachitsanzo, mu ma mota ang'onoang'ono omwe amakonda kugwiritsa ntchito zinthu zosiyanasiyana, maburashi a kaboni nthawi zambiri amagwiritsidwa ntchito chifukwa cha mtengo wake komanso kudalirika kwawo.

Brush DC Motors (m'lingaliro lalikulu)Maburashi mu ma mota a DC omwe si a kaboni amatha kupangidwa kuchokera ku zipangizo zosiyanasiyana. Mwachitsanzo, maburashi achitsulo ndi graphite amaphatikiza mphamvu zamagetsi zambiri za zitsulo (monga mkuwa) ndi mphamvu zodzipaka mafuta komanso zosatha za graphite. Maburashi amenewa nthawi zambiri amagwiritsidwa ntchito pamene mphamvu yonyamula mphamvu ikufunika.

Kuyanjana kwa Ogwira Ntchito

Mpweya wa Burashi wa DC MotorsMaburashi a kaboni amatsetsereka bwino pamwamba pa commutator. Kapangidwe ka kaboni kodzipaka mafuta kumathandiza kuti mphamvu yolumikizana ikhale yogwirizana nthawi zonse, zomwe ndizofunikira kwambiri kuti magetsi azilumikizana bwino. Nthawi zina, maburashi a kaboni amathanso kutulutsa phokoso lochepa lamagetsi panthawi yogwira ntchito, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito mosavuta chifukwa cha kusokonezedwa ndi maginito.

Burashi DC Motors yokhala ndi maburashi osiyanasiyana: Maburashi achitsulo - graphite, chifukwa cha makhalidwe awo osiyanasiyana, angafunike kapangidwe kosiyana ka commutator. Kuchuluka kwa mphamvu ya gawo lachitsulo kungayambitse mitundu yosiyanasiyana ya magawidwe amagetsi pamwamba pa commutator, motero, commutator ingafunike kupangidwa kuti izigwira ntchito bwino kwambiri.

Kusiyana kwa Magwiridwe Antchito

Mphamvu ndi Kuchita Bwino

Mpweya wa Burashi wa DC Motors: Kawirikawiri, ma mota a DC a carbon brush ndi oyenera kugwiritsa ntchito mphamvu zochepa mpaka zapakati. Kutsika kwa mphamvu zawo poyerekeza ndi ma mota ena achitsulo kungayambitse kukana kwamagetsi kwakukulu, zomwe zingayambitse kutayika kwa mphamvu zina monga kutentha. Komabe, mafuta awo odzipaka okha amachepetsa kutayika kwa makina chifukwa cha kukangana, zomwe zimathandiza kuti zinthu zigwire bwino ntchito. Mwachitsanzo, m'zida zazing'ono zapakhomo monga mafani amagetsi, ma mota a DC a carbon brush amagwiritsidwa ntchito nthawi zambiri, kupereka mphamvu zokwanira pomwe mphamvu zotsalazo - zogwira ntchito mokwanira panyumba.

Burashi DC Motors yokhala ndi maburashi osiyanasiyana: Ma mota okhala ndi maburashi achitsulo - graphite nthawi zambiri amagwiritsidwa ntchito pakugwiritsa ntchito mphamvu zambiri. Mphamvu yamagetsi yapamwamba ya gawo lachitsulo imalola kusamutsa bwino mphamvu zambiri, zomwe zimapangitsa kuti mphamvu zambiri zituluke. Makina a mafakitale, monga makina akuluakulu otumizira, nthawi zambiri amagwiritsa ntchito mitundu iyi ya ma mota kuyendetsa katundu wolemera.

Kulamulira Liwiro

Mpweya wa Burashi wa DC Motors: Kulamulira liwiro la ma mota a DC a carbon brush kungatheke kudzera m'njira zosiyanasiyana, monga kusintha magetsi olowera. Komabe, chifukwa cha makhalidwe awo enieni, sangapereke mulingo wofanana wa kuwongolera liwiro monga mitundu ina ya ma mota. Mu ntchito zomwe kukhazikika kwa liwiro sikofunikira kwambiri, monga m'mafani ena osavuta opumira mpweya, ma mota a DC a carbon brush amatha kugwira ntchito mokwanira.

Burashi DC Motors yokhala ndi maburashi osiyanasiyana: Nthawi zina, makamaka ndi zipangizo zamakono komanso mapangidwe apamwamba a burashi, kuwongolera bwino liwiro kumatha kuchitika. Kutha kuthana ndi mafunde amphamvu komanso kulumikizana kwamagetsi kokhazikika kungathandize njira zamakono zowongolera liwiro, monga kugwiritsa ntchito pulse - width modulation (PWM) bwino kwambiri. Ma servo motors ogwira ntchito kwambiri, omwe amafunikira kuwongolera liwiro molondola pa ntchito monga robotics, angagwiritse ntchito maburashi okhala ndi zipangizo zapadera pachifukwa ichi.

Zochitika Zogwiritsira Ntchito

Mpweya wa Burashi wa DC Motors

Zamagetsi Zamagetsi Zamagetsi: Amagwiritsidwa ntchito kwambiri m'magetsi ang'onoang'ono monga maburashi amagetsi, zowumitsira tsitsi, ndi mafani onyamulika. Kukula kwawo kochepa, mtengo wotsika, komanso magwiridwe antchito okwanira zimakwaniritsa zofunikira za zidazi.

Zida zamagalimoto: M'magalimoto, ma mota a DC a carbon brush amagwiritsidwa ntchito m'magwiritsidwe ntchito monga ma wipers a galasi lakutsogolo, mawindo amagetsi, ndi zosinthira mipando. Ma mota awa ayenera kukhala odalirika komanso otsika mtengo, ndipo ma mota a DC a carbon brush ndi oyenera.

Burashi DC Motorsndi maburashi osiyanasiyana

Makina a MafakitaleMonga tanenera kale, m'mafakitale, ma mota okhala ndi maburashi amphamvu amagwiritsidwa ntchito poyendetsa zida zazikulu. Mu fakitale yopanga, ma mota omwe amagwiritsa ntchito mapampu akuluakulu, ma compressor, ndi makina opera nthawi zambiri amafunikira mphamvu zambiri komanso kuwongolera molondola, komwe kungaperekedwe ndi ma mota a DC a burashi okhala ndi zida zoyenera za burashi.

Ndege ndi Chitetezo: Mu ntchito zina zapamlengalenga, monga ma actuator a ndege, ma brush DC motors okhala ndi maburashi apadera amagwiritsidwa ntchito. Ma brush motors amenewa amafunika kugwira ntchito pansi pa mikhalidwe yovuta kwambiri, kuphatikizapo kutentha kwambiri komanso malo ogwedezeka kwambiri. Kusankha zipangizo za burashi ndikofunikira kuti zitsimikizire kuti ntchito yodalirika ikugwira ntchito bwino pamikhalidwe yovuta ngati imeneyi.

Pomaliza, ngakhale kuti ma mota a carbon brush DC ndi mtundu wa mota wa brush DC, kusiyana kwa zipangizo za brush ndi makhalidwe ogwirira ntchito kumabweretsa zochitika zosiyanasiyana zogwiritsidwa ntchito. Kumvetsetsa kusiyana kumeneku ndikofunikira kwa mainjiniya ndi opanga popanga posankha mota wa DC woyenera kwambiri pa ntchito inayake.
