Mu nganda no mu bucuruzi, moteri yamahoro ikoreshwa cyane kubera imikorere yabo yo hejuru no gutanga umusaruro mwinshi. Ariko, kubara voltage ya romor ya moteri yimpeta ntabwo aribikorwa byoroshye, bidusaba kumva neza amahame nibipimo bifitanye isano nacyo. Iyi ngingo izamenyekanisha muburyo burambuye uburyo bwo kubara neza voltage ya rotor yimodoka yimpeta kugirango igufashe kunoza imikorere no gukora neza.
1. Intambwe shingiro zo kubara rotor voltage
(I) Menya voltage yatanzwe na moteri
Voltage yatanzwe na moteri ni voltage isanzwe kubishushanyo mbonera nibikorwa, bishobora kuboneka byoroshye mubisobanuro bya tekiniki. Agaciro ni imfuruka yo kubara nyuma, kimwe nkurufatiro rwinyubako ndende, itanga amakuru yibanze yo kubara. Kurugero, moteri yimpeta mubikoresho byinganda ifite voltage yinganda za 380 V hashyizweho ikimenyetso cya tekiniki, aricyo gihe cyo gutangira kubara.
. Kurwanya Rotor nimwe mubintu byingenzi bireba voltage rotor, kandi agaciro kagaciro kayo kajyanye no kwizerwa kubisubizo byanyuma. Dufashe ko kurwanywa rotor twapimye ni 0.4ω, aya makuru azagira uruhare runini mubare wakurikiyeho.
. Gufata voltage yatanzwe na 380 v hamwe na rotor irwanya 0.4ω yavuzwe haruguru nkurugero, vol voltage = 380 v × 0.4 = 152 V.
2. Isesengura ryimbitse rya Rotor Vorittage formula
(I) Ibigize kandi bifite akamaro ka formula
Inzira ya Rotor Voltage nimvugo yimibare izirikana ibintu byinshi. Bikomoka bishingiye kumahame shingiro ya electonagnesm. Muri bo, voltage ya stator, kunyerera hamwe nibiranga imizigo niyo ifite ingaruka zikomeye. Gusobanukirwa neza iyi formula yemerera injeniyeri guhanura neza imyitwarire ya moteri munsi yimiterere itandukanye, kimwe no kugira urufunguzo rwo gufungura amayobera yimikorere.
(Ii) Inkunga ya formula hamwe nibisabwa bifatika bishingiye kumahame ya elecromagnetics
Inzira yo gusiga ya Rotor Vortage Statula nimbaraga kandi zigoye. Irerekana isano ya hafi hagati yumurima wa magneti nuburi imbere muri moteri, kandi ifite akamaro kasohotse mu murima wo kugenzura no gushushanya. Mubikorwa bifatika, hamwe nubufasha bwumuhanda wa Rootor wabigize umwuga, injeniyeri ukeneye gusa kugirango winjiremo ibipimo bikenewe nka feri ya moteri no kunyerera kugirango ubone agaciro gake. Ibi ntibiteze imbere cyane imikorere imikorere, ariko kandi bireba ko moteri ikora muburyo bukomeye mubikorwa byiza.
3. Rotor Ibiriho Kubara hamwe no Gutezimbere moteri
(I) ibisobanuro birambuye bya rotor formulaire
Formula ni, ni = vt / zt, aho vt ari vol voltage na zt numwobo wa rotor. Kubara Rotor Voltage bikubiyemo ibintu nka voltator svorator no kunyerera, bisaba abanyamwuga b'amashanyarazi na gushyiramo iyi fomubure neza kugirango usuzume neza imikorere ya moteri.
(Ii) akamaro ko kubara rotor kurubu
Kubara Rotor Ikigezweho ni ngombwa kuri injeniyeri muburyo bwinshi. Ku ruhande rumwe, bifasha gusuzuma ubushobozi bw'ikirego z'amashanyarazi, kwemerera abashinzwe gutanga ubumenyi neza guhanura imyitwarire ihinduka moteri zitandukanye. Kurugero, mugihe cya moteri gahunda yo gutangiza, mugukurikirana impinduka muri rotor iriho, injeniyeri irashobora kumenya niba moteri itangira mubisanzwe kandi niba hari ibibazo nko kurenza urugero. Kurundi ruhande, ukurikirana no gusesengura rotor kurubu, birashoboka kugera ku kugenzura ibintu bishobora kuba byoroshye nka moteri .
4. Uruhare rwingenzi rwo kunyerera muri rotor oldiage
(I) ibisobanuro no kubara kunyerera
Kunyerera bisobanurwa nkitandukaniro ryihuse hagati yumurima uzunguruka na rotor, byagaragajwe nkijanisha ryumuvuduko wa synchrousFormula ni s = (n8-nt) / ns, aho slip, n8 numuvuduko wa synchrous, na NT numwihuta.
Kurugero, muburyo bwihariye bwo gukora moteri, niba umuvuduko wa synchrous ari 1500 rpm hamwe numuvuduko wa rotor ni 1440 rpm, kunyereraS = (1500-1440) /1500=0.04, 4%.
(Ii) Isano iri hagati yinyerera na rotor
Hariho isano ya hafi hagati yimbere kumurongo no guhinduranya. Mubisanzwe, rotor akeneye kunyerera runaka kugirango itange torque kandi igere kubikorwa bisanzwe bya moteri. Ariko, kunyerera cyane bizaganisha ku gutakaza igihombo cyo kurwanya no kugabanya ibisohokanire inoti, bizagira ingaruka zikomeye ku bijyanye n'imikorere ya moteri. Ibinyuranye, urupapuro rwo hasi cyane gishobora gutuma moteri yiruka hafi yigihugu gihuje igitsina, ariko izacogora ubushobozi bwa moteri nubushobozi bwo hanze ya Torque. Kubwibyo, mugihe cyo gushushanya moteri no gukora, kubara neza kunyerera no guhindura ibintu bifatika bikoreshwa kugirango bikoreshe byuzuye kandi bihanishwa neza kandi bihamye byimitwaro itandukanye.
V. Uburyo bwo guhindura Rotor Kurwanya Moteri
(I) Kamere n'ingaruka za Rotor Kurwanya
Kurwanya Rotor bivuga kurwanya umuzenguruko wa rotor ujya kurumbuka. Agaciro kayo gafite ingaruka zikomeye kuri TORQUEL TORQUE, AMATEGEKO YUMUZIRA NO GUKORA MOTOM. Kurwanya rotor nyinshi bifasha kunoza torque yo gutangira moteri no gukora moteri yo gutangira neza munsi yumutwaro uremereye. Ariko, mugihe gito cyibikorwa bya moteri, itandukaniro rikomeye rizatera igihombo cyingufu nyinshi, bityo bigabanya imikorere ikora ya moteri.
(Ii) formulaire ya rotor na faark isuzuma
Amata ya Rotor (ubusanzwe agaragazwa nka RT) yita ku bintu nkibintu byumubiri byibintu bya rotor, roor geometrie nubushyuhe nubushyuhe. Kubara neza kwa Rotor ni ngombwa kugirango ushyire mu bikorwa Rotor Voltage. Mu rwego rwo kwisuzumisha moto no kubungabunga ibinyabiziga, mugukurikirana impinduka zirwanya Rotor, ibibazo bishobora kuba bingana na kwambara kimwe, havumburwa no gukomera cyangwa gukomera birashobora kuvumburwa mugihe gikwiye. Kurugero, niba induru ya Rotor iboneka ko yiyongera gitunguranye, birashobora gusobanura ko hari umuzunguruko mugufi cyangwa umukene mubi rotor. Abakozi bashinzwe kubungabunga barashobora noneho gufata ingamba zo kubungabunga igitero kugirango ibungabunge neza ibintu byatsinzwe, ongera ubuzima bwa moteri, kandi birekuze ko bikomeza no gutuza kwumusaruro.
Vi. Ingero zo kubara hamwe nubuhanga bwo gusaba muburyo nyabwo
(I) urugero rwiza rwo kubara
Tuvuge ko hari moteri yimpeta hamwe na stator voltage ya 440 v, rotor irwanya 0.35ω, nurupapuro 0.03. Ubwa mbere, ukurikije Rototor Vorttage Vetor VT = s * vs, rotor vomitage vt = 0.03 * 440 = 13.2 V irashobora kuboneka. Noneho, ukoresheje rotor igezweho ni = vt / zt (ukeka ko rotor impetonce zt ni 0.5ω), rotor iriho = 13.4 = 26.4 A irashobora kubarwa.
(Ii) ubuhanga bwo gusaba n'ingamba mu bikorwa bifatika
Kugirango tumenye neza kandi twizewe kubisubizo byo kubara, ingingo zikurikira zigomba kwitonderwa: Icya mbere, koresha ibikoresho bipimisha cyane kugirango ubone ibipimo bya moteri. Kurugero, mugihe upima Rotor Kurwanya hamwe na Ohmmeter, igikoresho gifite imyanzuro yo hejuru kandi ikosa rito rigomba gutoranywa; Icya kabiri, mugihe winjije ibipimo byo kubara, menya neza ko ibice bigize ibipimo bihujwe kugirango wirinde gutandukana mubisubizo byo kubara kubera amakosa yo guhinduka; Icya gatatu, gusesengura uhuza ibidukikije hamwe n'imikorere mibi ya moteri, nk'urugero, urebye ingaruka z'ubushyuhe bwo kurwanya i Roto, mu bushyuhe bwo hejuru, kandi ibisubizo byo kubara bigomba gukosorwa mu buryo bukwiye .
Binyuze muri ibi byavuzwe haruguru kandi byimbitse intangiriro, nizera ko ufite gusobanukirwa neza uburyo bwo kubara kunyerera-impeta ya moteri ya romor hamwe n'akamaro kayo. Mubyukuri mubikorwa, gukurikira rwose intambwe zo kubara kandi urebye byimazeyo ibintu bitandukanye bizagufasha gutanga ikinamico yumurimo uhinduranya moteri yimodoka, kunoza imikorere yumuntu mubikorwa no kugabanya ibiciro byo kubungabunga ibikoresho.
Niki kigomba kwitabwaho mugihe cyo kubara voltage ya rotor ya moteri yimpeta?
- Igisubizo.
- B.Mubwumvikane buke kandi busaba
- c.Imiterere yakazi hamwe nakazi
- D.Gilculation inzira nibikoresho
