Burashi Yopaka Mpweya RS93/EH7U
Mafotokozedwe Akatundu
Gwiritsani ntchito zinthu ziwiri za theka la siliva ndi theka la kaboni, zokhala ndi mphamvu zamagetsi komanso mafuta abwino, zoyenera kugwiritsidwa ntchito ngati shaft current yamphamvu.

Magawo aukadaulo
Ntchito ya maburashi a kaboni okhazikika m'makina amagetsi ndi yofunika kwambiri pa ntchito zosiyanasiyana. Maburashi a kaboni ndi ofunikira kuti zitsimikizire kuti ma mota amagwira ntchito bwino komanso kuti mphamvu yamagetsi ikuyenda bwino, zomwe zimagwiritsidwa ntchito ngati zigawo zofunika kwambiri mu ma mota a DC opangidwa ndi burashi komanso opanda burashi, komanso mitundu ina ya ma mota a AC.
Mu ma mota a DC opangidwa ndi brushed, maburashi a kaboni ali ndi ntchito zingapo zofunika. Choyamba, amapereka mphamvu yakunja kapena yosonkhezera ku rotor yozungulira, yomwe imagwira ntchito ngati njira yoyendetsera, yomwe ndi yofunika kwambiri pakugwira ntchito kwa mota. Kuphatikiza apo, burashi ya kaboni imayambitsa mphamvu yosasunthika pa rotor shaft, ndikuyiyika pansi bwino. Burashi ya kaboni yokhazikika iyi imathandizira mphamvu yotulutsa, ndikulimbikitsa kuyenda kwa magetsi nthawi zonse mkati mwa dongosolo. Imathandizanso kusintha komwe mphamvu ikupita, ndipo mu ma mota a commutator, imathandizira njira yosinthira. Kuphatikiza apo, burashi imalumikiza rotor shaft ku chipangizo choteteza kuti ikhazikike pansi ndipo imalola kuyeza ma voltage abwino ndi oipa poyerekeza ndi nthaka.
Chosinthira, chopangidwa ndi maburashi ndi mphete zosinthira, ndi gawo lofunikira kwambiri mu ma mota a DC osinthidwa. Chifukwa cha kuzungulira kwa rotor, burashi nthawi zonse imakhala ndi kukangana motsutsana ndi mphete yosinthira, zomwe zingayambitse kuwonongeka kwa mphamvu panthawi yosinthira. Kuwonongeka kumeneku kumagawa burashi ya kaboni ngati gawo logwiritsidwa ntchito mu ma mota a DC. Pofuna kuchepetsa mavutowa, ma mota a DC opanda burashi apangidwa ngati njira ina yolimba kwambiri, cholinga chake ndikuwonjezera moyo wautumiki, kukhazikika kwa ntchito, komanso kuchepetsa phokoso ndi kusokoneza kwa ma elekitiromagineti.
N'zochititsa chidwi kuti ma mota a AC nthawi zambiri sagwiritsa ntchito maburashi kapena commutator, chifukwa amagwira ntchito popanda mphamvu ya maginito yokhazikika. Komabe, ma mota a AC nthawi zambiri amakhala akuluakulu kuposa ma DC ena. Kusiyana kumeneku kukuwonetsa kufunika kwa maburashi a kaboni pakugwira ntchito kwa ma mota a DC ndipo kukuwonetsa kupita patsogolo kwaukadaulo wamagalimoto.
Mwachidule, ntchito ya maburashi a kaboni opangidwa pansi ndi yofunika kwambiri pakugwira bwino ntchito kwa mitundu yosiyanasiyana ya injini. Pamene ukadaulo ukupitirira, kufunika kwa maburashi a kaboni m'makina amagetsi kumakhalabe chinthu chofunikira kwambiri pakutsimikizira kuti injini ikugwira ntchito bwino komanso kudalirika.
