Udindo wa maburashi a kaboni mu mota

Maburashi a kaboni amagwiritsidwa ntchito pakati pa magawo osasunthika komanso ozungulira a mota, ma jenereta kapena makina ena ozungulira ndikukhala chimodzi mwazinthu zofunika kwambiri. Monga cholumikizira chotsetsereka, maburashi a kaboni amagwiritsidwa ntchito kwambiri pazida zambiri zamagetsi. Zida mankhwala makamaka electrochemical graphite, kudzoza graphite, zitsulo (kuphatikizapo mkuwa, siliva) graphite. Mawonekedwe ake ndi amakona anayi, ndipo waya wachitsulo amaikidwa m'chaka. Burashi ya kaboni ndi gawo lolumikizana lotsetsereka, kotero ndilosavuta kuvala ndipo liyenera kusinthidwa ndikutsukidwa pafupipafupi.

Ntchito ya burashi ya kaboni ndikuyambitsa makina ozungulira omwe amafunidwa ndi ma mota mu koyilo ya rotor kudzera pachidutswa cholumikizira pa mphete yolumikizira. Kuyenerera ndi kusalala kwa burashi ya kaboni ndi chidutswa cholumikizira, ndi kukula kwa malo okhudzidwa kumakhudza moyo wake ndi kudalirika. Mu mota ya DC, imagwiranso ntchito yosinthira (kukonza) mphamvu yosinthira ma elekitirodi yomwe imapangitsidwa ndi mafunde a armature.

Ma commutator amapangidwa ndi maburashi ndi mphete zosinthira, ndipo maburashi a kaboni ndi mtundu umodzi wa maburashi. Chifukwa cha kusinthasintha kwa rotor, maburashi nthawi zonse amapakidwa ndi mphete yosinthira, ndipo kukokoloka kwamoto kudzachitika panthawi yakusintha, chifukwa chake maburashi ndiye mbali zovala mu mota ya DC.
