Imathiriyeli yephepha lokugquma umbane licandelo elibalulekileyo leenjini zehabhu, njengoko inceda ukukhusela ukujika kwemoto emonakalweni kwaye ithintela iibhulukhwe zombane.
Ukongeza ekukhuseleni i-motor winding emonakalweni, iphepha lokugquma likwanceda ekuphuculeni ukusebenza kakuhle kwemoto. Ngokunciphisa amathuba ombane omfutshane kunye nezinye iindlela zomonakalo, iphepha lokukhusela linokunceda ekuqinisekiseni ukuba i-motor isebenza kwinqanaba eliphezulu, inikezela ngokuthembekileyo nokusebenza ngokufanelekileyo.
Amaphepha okugquma umbane alungele i-machicle yombane, imoto yamandla amatsha, iibhayisekile zombane, izithuthuthu, kunye nezinye izithuthi.
