Ibara ry'uruhu rishyirwa mu bice by'umubiri bikwiye ku kigero cy'imigongo ibihumbi byinshi ku munota.
Mu mashini zigezweho zo gushushanyaho, urushinge rukoreshwa na moteri y'amashanyarazi. Ubwiza bw'icyo gikoresho ni ingenzi cyane kandi kigomba kuba kidahindagurika kandi kigakora buhoro buhoro uko bishoboka kose. Kubera ko gushushanyaho bishobora kumara amasaha menshi icyarimwe, mashini igomba kuba yoroheje cyane, ariko igatanga imbaraga zikenewe -- kandi igakora tatouage nyinshi mu gihe kirekire. Abakoresha DC bakomeye bo mu byuma bikoresha ibyuma binini n'abakoresha DC badafite brushless bafite abakoresha bagenzura umuvuduko bubatswemo ni beza cyane kugira ngo buzuze ibi bisabwa. Bapima garama 20 kugeza kuri 60 gusa, bitewe n'icyitegererezo, kandi bakora neza 92%.

Imashini zikoreshwa zigomba kuba zujuje ibisabwa mu rwego rwa tekiniki n'imiterere yazo kandi zigakora neza kandi mu buryo bwizewe. Kubera ko igikorwa gikorerwa hafi y'ibice by'umubiri byoroshye, nk'amaso, igikoresho kigomba kuba gito cyane mu gihe gikoreshwa. Kubera ko imiterere y'igikoresho ari ndende kandi nto, ni byiza kuba kingana n'ikaramu y'umupira, bityo ikaba ikwiriye cyane kuri micromoteri za DC zoroshye cyane.
Kubera imiterere myiza ya tekiniki, moteri yacu ifite ubushobozi bwo gukora neza cyane, ibyo bikaba ingirakamaro cyane ku buryo bateri ikoreshwa.
Ubucucike bw'ingufu nyinshi butuma habaho uburyo bworoshye bwo gutwara ibintu, nk'ubugari bwa mm 16 ku bikoresho byo kwisiga bihoraho bifatwa mu ntoki.
Ugereranyije na moteri rusange ya DC, ibikoresho byacu biratandukanye muri rotor. Ntabwo izunguruka ku gice cy'icyuma, ahubwo igizwe n'umuringa wishingikirizaho.
