Ibyiza bimwe na bimwe by’ingufu za moteri zifite ingufu nyinshi byanze bikunze bizamenyekana kandi bigakundwa n’isoko.

Icyifuzo cyaMoteri za 10kVni kinini kuruta icyo kuriMoteri za 6kV, kandi iyo ubitekerejeho neza, ntabwo ari impamvu idafite ishingiro. Mu myaka ya vuba aha, hamwe no gushyira mu bikorwa politiki zo kuzigama ingufu no kuvugurura imiyoboro y'amashanyarazi yo mu gihugu kugira ngo bigabanye igihombo cy'imiyoboro, inganda n'ubucukuzi bw'amabuye y'agaciro byahisemo moteri ziciriritse za 10kV kugira ngo zisimbuze moteri za 6kV kugira ngo bigabanye ishoramari mu gukwirakwiza, bigatuma ubwiyongere bugaragara bw'ubukene bwa moteri ziciriritse za 10kV. Imwe mu mbogamizi za tekiniki z'izo moteri ni ugukingira hagati y'ingufu zaimiyoboro ya statorBitewe n'uko ibyuma bikunze kuba bito, biragoye gukoresha kaseti ya mica ipfunyitse intoki cyangwa ipfunyitse imashini. Gukoresha insinga zipfunyitse nk'ingufu zipfunyitse hagati y'imashini bituma habaho ubudahangarwa buke mu guhangana n'ikorosi. Mu gihe moteri zikora moteri zifite ingufu nyinshi, amakosa yo guhindukira hagati y'imashini aba menshi, kandi uburyo bwo gushyushya hagati y'imashini burushaho kuba bwiza. Bamwe mu bakoresha ndetse banavuga ko moteri zifite ingufu nyinshi zigomba gukoresha mica muuburinzi bw'inyuma hagati y'inyuma.

Ingamba zafashwe mu mahanga muri urwo rwego ni ugukoresha cyane micainsinga zipfunyitseMu Bushinwa, ubushakashatsi ku bijyanye no gukingira hagati y’impande hakoreshejwe ifu ya mica tape bwakozwe mu myaka ya vuba aha. Ku bufasha bwaibikoresho byo gukingirainganda n'inganda zikora moteri, zimwe muri zoamashanyaraziInganda z'insinga zakoze neza ubwoko butandukanye bw'insinga zipfunyitse za mica zifite imiterere itandukanye. Muri iki gihe, inganda nyinshi zikora moteri zirimo kuzishyiramo no kuziteza imbere.

Inyinshi mu makosa n'ibyangiritse bya moteri zizenguruka biterwa n'ibyangiritse bya insulation izunguruka. Muri zo, insulation izunguruka ingana na 50%. Kandi iyo yangiritse, ingaruka zizaba zikomeye. Inter-winding insulation short circuit iterwa ahanini n'agaciro ka voltage ya impulse ya moteri irenga voltage y'imikorere ya insulation ya zimwe muri windings mu bihe bitandukanye bya overvoltage. Zimwe ziterwa n'ibyangiritse bya mekanike ya coils na windings mu gihe cyo gukora, izindi ziterwa no gusohora amazi mu gace ka moteri ka high voltage windings na corona corruption ya high voltage windings. Ibyangiritse biterwa n'ibi bintu byose bifitanye isano mu buryo butaziguye cyangwa butaziguye n'imikorere y'insinga zizunguruka zikoreshwa muri moteri. Hamwe no kuvugurura no gusimbuza moteri zizunguruka no gukenera moteri zitandukanye zidasanzwe na moteri zirwanya ubushyuhe bwinshi, guteza imbere ubwoko bushya bw'insinga zizunguruka ni ngombwa.
