1. Kukonza kusintha kosayenda bwino kwa magetsi poika kapena kukonza ma poles oyendera: Iyi ndi njira yothandiza kwambiri yowonjezera kusintha kwa magetsi. Mphamvu ya maginito yomwe imapangidwa ndi ma poles oyendera magetsi imalimbana ndi mphamvu ya maginito yoyendera magetsi komanso imapanga mphamvu yomwe imalepheretsa mphamvu ya maginito yoyendera magetsi yomwe imayambitsidwa ndi inductance yozungulira, zomwe zimathandiza kuti magetsi asinthe bwino. Kutembenuza mphamvu ya ma poles oyendera magetsi kumalimbikitsa kuwala; gwiritsani ntchito kampasi kuti mutsimikizire polarity ndikusintha ma terminal olumikizidwa ndi chogwirira cha burashi kuti akonze. Ngati ma coil a commutator pole ali ndi ma short-circuit kapena open-circuit, konzani kapena kusintha ma coil nthawi yomweyo.
Sinthani malo a burashi: Kwa ma mota a DC okhala ndi mphamvu zochepa, kusintha kwa kusinthaku kungatheke posintha malo a burashi. Maburashi a ma mota osinthika ayenera kugwirizana bwino ndi mzere wa neutral; ma mota osasinthika amalola kusintha pang'ono pafupi ndi mzere wa neutral. Kupatuka kwa burashi kuchokera ku mzere wa neutral kumawonjezera kuwala. Gwiritsani ntchito njira yodziwitsira kuti mubwezeretse maburashi pamalo oyenera.
2. Kuthana ndi Kuchuluka kwa Mphamvu ya Maginito Pewani kuchuluka kwa mphamvu ya injini: Yang'anirani nthawi zonse mphamvu yamagetsi yogwiritsira ntchito ndikuyika zida zoteteza mphamvu yamagetsi zomwe zimazimitsa zokha kapena kuyambitsa ma alarm pamene mphamvu yamagetsi yapitirira mtengo wovomerezeka. Sankhani maginito moyenera kutengera zofunikira za katundu kuti mupewe kugwiritsa ntchito maginito amphamvu yamagetsi ochepa pazida zamagetsi amphamvu. Kuti katundu awonjezere kwakanthawi, onetsetsani mphamvu yamagetsi ndikuchepetsa nthawi yogwirira ntchito.
Linganizani mafunde a burashi ofanana: Sinthani ma brush springs kuti muzitha kusinthasintha kuti muwonetsetse kuti mphamvu ya burashi ndi yofanana pa maburashi onse. Yeretsani nthawi zonse malo olumikizirana pakati pa maburashi ndi zogwirira burashi kuti muchotse okosijeni ndi zinthu zodetsa, kuchepetsa kukana kwa kukhudzana. Gwiritsani ntchito maburashi okhala ndi zinthu zofanana ndi gulu pa chogwirira chomwecho kuti mupewe kufalikira kwa mphamvu ya burashi yosagwirizana chifukwa cha kusiyana kwa zinthu.
3. Konzani bwino zinthu za burashi ndi kusankha mtundu wa burashi: Sankhani maburashi kutengera momwe injini imagwirira ntchito monga magetsi, liwiro, ndi makhalidwe a katundu. Pa ma mota othamanga kwambiri komanso olemera, sankhani maburashi a graphite okhala ndi mphamvu yocheperako, kukana kuvala, komanso magwiridwe antchito abwino kwambiri. Pa ma mota olondola omwe amafuna mtundu wapamwamba wa kusintha, sankhani maburashi a carbon-graphite okhala ndi mphamvu yokhazikika yokhudzana ndi kukhudzana. Sinthani maburashi mwachangu ndi maburashi osinthidwa oyenera ngati kuwonongeka kwakukulu kapena kuwonongeka kwa pamwamba pa commutator.
