Ugereranije na rotor yibikomere, rotage ya cage ifite ubuziranenge numutekano ugereranije, ariko rotage ya cage nayo izagira ibibazo byubuziranenge mubihe hamwe no gutangira kenshi na inertia nini yo kuzunguruka.
Ugereranije, ubwiza bwubwiza bwa rot ya aluminiyumu nibyiza, utubari twa rotor duhujwe neza na rotor, kandi ubushobozi bwo kurwanya ubushyuhe mugihe cyo gutangira moteri birakomeye. Nyamara, inenge nziza nko kugabanuka nu mwobo utagaragara bibaho mugihe cyo guta aluminiyumu, kimwe nikibazo cyo kumena utubari twatewe no gushyushya rotor ntishobora kwirengagizwa, cyane cyane kubibazo byibikoresho bibi hamwe na aluminiyumu yo guta, ikibazo kirakomeye.
Iyo hari ikibazo kijyanye na rotor ya aluminium, irashobora kugenzurwa uhereye hejuru ya rotor hamwe nibindi bintu byiza bifite. Iyo rotor ifite ikibazo cyacitse, bizashyuha rwose, kandi hejuru ya rotor izaba ifite ubururu bugaragara igice cyangwa byuzuye. Mubihe bikomeye, hazaba amasaro ya aluminiyumu yakozwe nubushyuhe. Iki kibazo ahanini kibaho mugice cyo hagati cyumurongo. Iyo aluminiyumu ikora rotor ishyushye, impeta ya rotor nayo izahinduka. Mugihe gikomeye, umuyaga uhuha wa rotor uzajugunywa hanze kandi byangiza stator.
Kubirindiro bibiri byikariso, ibizunguruka byimbitse, roto imeze nkicupa, nibindi, bikoreshwa mugutezimbere imikorere yo gutangira, utubari twa rotor tumaze kumeneka, umwanya wo kumeneka ahanini ubera kumwanya wo gusudira hafi yimpeta yanyuma. Kumeneka kwinzira ya rotor biterwa ningaruka zasubiwemo nubushyuhe bwigihe kirekire cyumuriro, guhinduranya imbaraga za electromagnetique, imbaraga za centrifugal hamwe na tangensique tangensique, bizatera kunama numunaniro kwangirika. Utubari nimpeta zanyuma birashoboka cyane ko bifite ibibazo. Mugihe cyo gutangira moteri, kubera ingaruka zuruhu, utubari twa rotor turashyuha ku buryo butaringaniye, kandi utubari twa rotor duhangayikishwa no kugonda umurongo; iyo moteri ikora mubisanzwe, utubari twa rotor nimpeta zanyuma ziterwa ningufu za centrifugal, kandi utubari tubyara impagarara zunamye kure yumurongo. Izi mpungenge zizabangamira kwizerwa kumpera zombi za rotor bar. Kugirango tunoze ubwiza bwa rotor yo gusudira, tekinoroji yohasi yohasi ikoreshwa buhoro buhoro ikoreshwa muburyo bwo gusudira bwa rotor nini.
