Umuyoboro w'amashanyarazi ni wo wica cyane moteri zikoresha frequency ihindagurika, moteri nini,moteri zifite amashanyarazi menshin'imashini zitanga moteri, kandi byangiza cyane sisitemu yo gutwara moteri. Hari ingero nyinshi z'uko sisitemu yo gutwara moteri yangiritse bitewe n'uburyo amashanyarazi adahagije yo gukumira.
Ibiranga umuyoboro w'amashanyarazi ni voltage nkeya n'umuyoboro mwinshi w'amashanyarazi, kandi kwangirika kwa sisitemu y'ubwikorezi bishobora kuvugwa ko bigoye kwirinda. Ikorwa ry'umuyoboro w'amashanyarazi riterwa n'amashanyarazi y'umuyoboro n'uruziga rufunze. Kugira ngo ikibazo cy'umuyoboro w'amashanyarazi gikemuke, hari uburyo bubiri bwo kugikemura: gukuraho voltage y'umuyoboro cyangwa gukata urukiramende.
Kudahuza kwa magnetic circuit, gutanga amashanyarazi ya inverter, induction ya electrostatic, charge static hamwe no guhungabanya ingufu zo hanze byose bishobora gutanga voltage ya shaft. Ubusanzwe uburebure bwa voltage ya shaft ni buto, ariko iyo igeze ku gaciro runaka, izaca muri filime ya bearing lubricating peterol hanyuma inyure mu ruziga rufunze ku buso bw'ingufu. Umuriro munini wa shaft uzatuma bearing ishya bitewe n'ubushyuhe mu gihe gito cyane. Bearing ishyushye na shaft current izasiga ikimenyetso gisa n'ikibaho cyo kumesa ku buso bw'inyuma bw'ingufu.
Kugira ngo ikibazo cyo kwirinda umuvuduko w'amazi mu gice cy'umugozi gikemuke, ingamba zikenewe zigomba gufatwa mu gushushanya no gukora moteri, nko kongeramo ingamba zikenewe zo gukingira ku gice cyo hejuru cy'umupfundikizo n'agapfundikizo k'icyuma gikingira. Ku bicuruzwa bito, hashobora gukoreshwa udupfundikizo two gukingira, kandi hashobora kongerwamo uburoso bwa karuboni bushobora kuva mu gihe cyo kuyikoresha. Mu gihe cyo kuyikoresha, gufata ingamba zo guhagarika ibice ni ingamba ifatwa rimwe na rimwe, mu gihe gukoresha uburyo bwo kuyobya bishobora guteza ikibazo cyo gusimbuza igikoresho cya karuboni. Nibura, sisitemu ya karuboni ntigomba kugira ibibazo mu gihe cyo kuyitunganya.

Amapine y'ubushyuhe atwikiriwe
Ingano n'ubushobozi bw'imitwaro ya bearings zishyushye ni kimwe n'iz'ibyuma bisanzwe bya flange. Itandukaniro ni uko bearings zishyushye zishobora kubuza umuriro kunyura neza. Bearings zishyushye zishobora kwirinda kwangirika guterwa n'ingufu z'amashanyarazi. Kubwibyo, zishobora gukoreshwa muri moteri kugira ngo zikore neza kuruta bearings zisanzwe. Bearings zishyushye zishobora kwirinda ingaruka za electro-corrosion z'umuriro uterwa n'ingufu ku mabearings kandi zikarinda umuriro kwangiza amavuta, ibintu bizunguruka, n'inzira zo gusiganwa.

Kuki amashanyarazi ya inverter atuma amashanyarazi ya shaft atangwa?
Iyo moteri ikoresha umuriro ukoresha inverter, umuriro ukoresha amashanyarazi uba ugizwe n'ibice bifite harmonic nyinshi, bigatuma amashanyarazi akwirakwira hagati y'impera za stator winding coil, igice cy'insinga, n'umugozi uzenguruka, bityo bigatanga voltage ya shaft.
Umuzunguruko wa stator wamoteri idahuzaishyirwa mu mwanya wa stator core. Hariho ubushobozi bukwirakwira hagati y’izunguruka rya stator winding no hagati ya stator winding n’ishingiro rya moteri. Iyo general frequency converter ikoreshejwe kuri frequency yo hejuru, voltage isanzwe ya inverter irahinduka cyane, igakora amashanyarazi ava mu gisenge cya moteri ajya ku butaka binyuze mu bushobozi bukwirakwira bwa moteri winding. Iyi voltage ikwirakwira ishobora gukora ubwoko bubiri bwa electromagnetic interference, radiation na conductive. Bitewe n’ubusumbane bw’uruziga rwa magnetic rwa moteri, induction ya electrostatic na voltage isanzwe ya mode ni byo bitera voltage ya shaft na shaft current.
