Ibisohoka bya moteri y'ibyiciro bitatubigomba gutoranywa ukurikije imbaraga zisabwa nimashini zitanga umusaruro, kandi moteri yicyiciro cya gatatu ntigomba gukoreshwa munsi yumutwaro wagenwe bishoboka. Mugihe uhitamo ingufu za moteri, intego igomba kuba ikwiye.
Kubijyanye no gutoranya uburyo bwububasha bwaibyiciro bitatu bya asinchronous induction ACmotor.
Guhitamo moteri yicyiciro cya gatatu idafite imbaraga nimbaraga ntizishobora gusenya ingufu zamashanyarazi cyangwa kurenza moteri igihe kirekire. Niba ingufu za moteri ziri hasi cyane. Ibintu "bito bito" bibaho, bigatuma moteri iremererwa igihe kirekire, bigatuma ibikoresho byangiza byangirika nubushyuhe. Nubwo moteri yatwitse, niba imbaraga za moteri ari nini cyane, ibintu bya "marato nini" bizabaho. Imbaraga zayo zisohoka zishobora gukoreshwa byuzuye, imbaraga nimbaraga ntabwo ziri hejuru, kandi binatanga ingufu zamashanyarazi.
Uburyo 1: Koresha formula yo kubara imbaraga zisabwa na moteri yicyiciro cya gatatu:
- Kuburyo bukomeza bwo gukora, imbaraga zumutwaro (ni ukuvuga imbaraga kumashanyarazi) Pl (kW) irazwi. Inzira ikurikira irashobora gukoreshwa mukubara imbaraga P (kW) ya moteri: P = P1 / n1 n2 Aho n1 ari imbaraga zimashini itanga kandi n2 nimbaraga za moteri. Izi nimbaraga zo kohereza.
Ukurikije imbaraga zabonywe na formula yavuzwe haruguru, kubera ko imbaraga nibindi bidakeneye kuba byukuri, kandi gutakaza ingufu za mashini bifite impinduka zimwe, imbaraga zapimwe za moteri yatoranijwe zigomba kuba zingana cyangwa zirenze gato imbaraga zabazwe.
Niba anmoteri y'amashanyarazi hamwe nimbaraga za 0.8 zatoranijwe, gerageza umenye umubare wa kilowatt zingana na moteri igomba kuba. Igisubizo: P = P1 / n1n2 = 3.95 / 0.7 * 0.8 = 7.1kW Kubera ko nta bisobanuro bya 7.1kW, hatoranijwe moteri ya 7.5kW ibyiciro bitatu.
- Igikorwa cyigihe gito cyapimwe moteri. Ugereranije na moteri ifite imbaraga zingana mugihe gikora. Ibice bito, nini nini nini, nigiciro gito. Niba ibintu byemewe, moteri yicyiciro cya gatatu idafite moteri hamwe nigihe gito cya S2 igomba guhitamo bishoboka.
- Kubyiciro bitatu byimoteri idafite moteri hamwe nigihe gito cyo gukora cya S3, hitamo ingano y'ibisohoka. Ukurikije ubunini bwikigero cyo kwikorera imitwaro, hatoranijwe moteri yicyiciro cya gatatu idafite moteri hamwe na sisitemu yo gukora S3, ikoreshwa cyane mugikorwa cyigihe gito. Inzira yo kubara imitwaro Fs% gukomeza ni Fs% = tg / (Tg + kugeza) × 100%, aho Tg nigihe cyo gukora (unit: min), t ni torque yo guhagarika (unit: min); Tg icumi kugeza ni igihe cyizunguruka (unit: min)
Uburyo bwa 2: Koresha uburyo bwo kwigana kugirango uhitemo imbaraga za moteri yibice bitatu. Ibyo bita igereranya, bigereranywa nimikorere ya moteri yicyiciro cya gatatu idakoreshwa mumashini asa nayo.
Uburyo bwihariye ni: gusobanukirwa imbaraga zikoreshwa nimashini zibyara umusaruro hafi yiki gice cyangwa ibindi bice, hanyuma uhitemo moteri hafi kugirango ikore igeragezwa. Igikorwa cyo kugerageza kigamije kugenzura niba moteri yatoranijwe ihuye nimashini itanga umusaruro. Uburyo bwo kugenzura ni: kora amashanyarazi azamura imashini ikora. Koresha clamp ammeter kugirango upime imikorere ikora ya moteri yicyiciro cya gatatu idafite moteri, hanyuma ugereranye ibisubizo byo gupimwa numuyoboro wagenwe washyizwe kumurongo.
Uburyo bwa 3: Uburyo bwo gusuzuma bukwiye:
- Niba ibikorwa byukuri bya moteri bidatandukana cyane kuva nominal yerekanwe. Ibi byerekana ko imikorere ya moteri yatoranijwe ihagije.
- Niba ibikorwa byukuri bya moteri biri munsi ya 70% munsi yumurongo wagenwe ugaragara kurutonde. Noneho byerekana ko imbaraga za moteri ari ndende cyane (ni ukuvuga "gari ya moshi nini" igomba gusimburwa na moteri ifite imbaraga nke).
- Niba moteri yapimwe ikora ikora irenga 40% kurenza ingufu zagenwe zerekanwe kurutonde. Ibi byerekana ko imbaraga za moteri ziri hasi cyane (ni ukuvuga "gare nto"), ni ukuvuga moteri nini nini igomba gusimburwa.
