Palibe kusiyana pakati pa kaboni burashi DC mota ndi burashi DC mota kwenikweni, monga maburashi amagwiritsidwa ntchitoDC moterenthawi zambiri amakhala maburashi a carbon. Komabe, pofuna kumveka bwino muzinthu zina, ziwirizi zikhoza kutchulidwa ndikufanizidwa ndi mitundu ina ya injini. Zotsatirazi ndi kufotokozera mwatsatanetsatane:

Brush DC Motor

• Mfundo Yogwirira Ntchito: Galimoto ya DC yopangidwa ndi brushed imagwira ntchito pa mfundo za electromagnetic induction ndi lamulo la Ampere6. Zimapangidwa ndi zinthu monga stator, rotor, maburashi, ndi commutator. Gwero lamagetsi la DC likapereka mphamvu ku mota kudzera m'maburashi, stator imapanga mphamvu yamagetsi yokhazikika, ndipo rotor, yolumikizidwa ndi gwero lamagetsi kudzera pa maburashi ndi ma commutator, imapanga mphamvu yozungulira yozungulira. Kulumikizana pakati pa gawo lozungulira la maginito ndi gawo la stator kumatulutsa torque yamagetsi, yomwe imayendetsa mota kuti izungulire. Pogwira ntchito, maburashi amasunthika pa commutator kuti asinthe mphamvu yamagetsi ndikupangitsa kuti injiniyo ikhale yozungulira mosalekeza6.
• Makhalidwe Apangidwe: Ili ndi mawonekedwe osavuta, makamaka kuphatikiza stator, rotor, maburashi, ndi commutator. Stator nthawi zambiri imapangidwa ndi mapepala achitsulo a silicon okhala ndi ma windings ozungulira. Rotor imakhala ndi pakati pachitsulo ndi ma windings, ndipo ma windings amalumikizidwa ndi magetsi kudzera pa maburashi6.
• Ubwino wake: Uli ndi ubwino wa kapangidwe kake komanso mtengo wotsika, zomwe zimapangitsa kuti zikhale zosavuta kupanga ndi kukonza. Ilinso ndi ntchito yabwino yoyambira ndipo imatha kupereka torque6 yayikulu.
• Kuipa kwake: Kukangana ndi kuwotcha pakati pa maburashi ndi ma commutator panthawi yogwira ntchito kumayambitsa kuwonongeka, kumachepetsa mphamvu ya injini ndi moyo wautali. Kuphatikiza apo, magwiridwe antchito ake amawongolera liwiro ndizovuta, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa liwiro lolondola6.

Carbon Brush DC Motor

• Mfundo Yogwirira Ntchito: Galimoto ya kaboni burashi ya DC imakhala injini ya DC yopukutidwa, ndipo mfundo yake yogwirira ntchito ndi yofanana ndi mota ya DC yomwe yafotokozedwa pamwambapa. Burashi ya kaboni imalumikizana ndi commutator, ndipo pamene commutator ikuzungulira, burashi ya carbon imasintha mosalekeza njira yapano mu koyilo ya rotor kuti zitsimikizire kusinthasintha kosalekeza kwa rotor.
• Makhalidwe Apangidwe: Kapangidwe kake kamakhala kofanana ndi ka motor brushed DC, kuphatikiza stator, rotor, carbon brush, ndi commutator. Burashi ya kaboni nthawi zambiri imapangidwa ndi graphite kapena chisakanizo cha graphite ndi ufa wachitsulo, womwe uli ndi mphamvu zabwino zamagetsi komanso zodzipaka mafuta, kuchepetsa kung'ambika pakati pa burashi ndi commutator pamlingo wina.
• Ubwino wake: Burashi ya kaboni imakhala ndi zinthu zabwino zodzitchinjiriza komanso zosavala, zomwe zimatha kuchepetsa kuchuluka kwa maburashi ndi kukonzanso. Ilinso ndi madulidwe abwino amagetsi ndipo imatha kuonetsetsa kuti injiniyo ikuyenda bwino.
• Zoipa: Ngakhale burashi ya kaboni imakhala yabwino kukana kuvala kuposa maburashi wamba, imafunikabe kusinthidwa pafupipafupi. Kuonjezera apo, kugwiritsa ntchito maburashi a carbon kungapangitsenso ufa wa carbon, womwe umayenera kutsukidwa nthawi zonse kuti usasokoneze kayendetsedwe ka galimoto.
