Imbaraga za moteri zigomba gutoranywa ukurikije imbaraga zisabwa n’imashini zitanga umusaruro kugirango moteri ikore munsi yumutwaro wagenwe uko bishoboka. Ingingo ebyiri zikurikira zigomba kwitabwaho muguhitamo:
① Niba imbaraga za moteri ari nto cyane, ibintu byo "ifarashi nto ikurura igare" bizagaragara, bikaviramo umuvuduko muremure wa moteri, bigatuma kwangirika kwayo kubera gushyuha, ndetse na moteri irashya.
② Niba imbaraga za moteri ari nini cyane, ibintu bya "ifarashi nini ikurura imodoka nto" bizagaragara. Imbaraga za mashini zisohoka ntizishobora gukoreshwa byuzuye, kandi imbaraga nimbaraga ntizihagije, ibyo ntibibangamira gusa abakoresha na gride ya power. Kandi ni uguta imbaraga.
Guhitamo imbaraga za moteri neza, kubara cyangwa kugereranya bikurikira bigomba gukorwa:
P = f * V / 1000 (P = imbaraga zabazwe kW, f = zisabwa gukurura imbaraga N, umuvuduko wumurongo wimashini ikora M / s)
Kuburyo bwimitwaro ihoraho ikora, imbaraga za moteri zisabwa zirashobora kubarwa ukurikije formula ikurikira:
P1 (kw) ： P = P / n1n2
Aho N1 nubushobozi bwimashini zitanga umusaruro; N2 nubushobozi bwa moteri, ni ukuvuga uburyo bwo kohereza.
Imbaraga P1 zabazwe na formula yavuzwe haruguru ntabwo byanze bikunze zingana nimbaraga zibicuruzwa. Kubwibyo, imbaraga zapimwe moteri yatoranijwe igomba kuba ingana cyangwa iruta gato imbaraga zabazwe.
Mubyongeyeho, uburyo bukoreshwa cyane ni uguhitamo imbaraga. Ibyo bita kugereranya. Ugereranijwe nimbaraga za moteri ikoreshwa mumashini asa nayo.
Uburyo bwihariye ni: menya uburyo moteri yingufu zikoreshwa zikoreshwa mumashini asa niki gice cyangwa ibindi bice byegeranye, hanyuma uhitemo moteri ifite imbaraga zisa zo gukora ikizamini. Intego yo gutangiza ni ukugenzura niba moteri yatoranijwe ihuye n'imashini zitanga umusaruro.
Uburyo bwo kugenzura ni: kora moteri itwara imashini zitanga umusaruro kugirango zikore, gupima imiyoboro ikora ya moteri hamwe na ammeter ya clamp, hanyuma ugereranye umuyaga wapimwe numuyoboro wagenwe washyizwe kumurongo. Niba ibikorwa byukuri bya moteri bidatandukanye numuyoboro wagenwe washyizwe kumurongo, imbaraga za moteri yatoranijwe irakwiriye. Niba moteri ikora ya moteri iri munsi ya 70% ugereranije nu gipimo cyagenwe cyerekanwe ku cyapa cyerekana, byerekana ko imbaraga za moteri ari nini cyane, kandi moteri ifite imbaraga zo hasi igomba gusimburwa. Niba imashini ikora yapimwe ya moteri irenze 40% kurenza igipimo cyagenwe cyerekanwe ku cyapa cyerekana, byerekana ko imbaraga za moteri ari nto cyane, kandi moteri ifite ingufu zisumba izindi zigomba gusimburwa.
Mubyukuri, torque (torque) igomba kwitabwaho. Hano hari formulaire yo kubara imbaraga za moteri na torque.
Ni ukuvuga, t = 9550p / n
Aho:
P-power, kW;
N-umuvuduko wa moteri, R / min;
T-torque, nm.
Ibisohoka bya moteri bigomba kuba binini kuruta itara risabwa n'imashini zikora, muri rusange bisaba ikintu cyumutekano.
