Ni irihe tandukaniro riri hagati ya moteri ihindagurika na moteri isanzwe?

Moteri zisanzwe zakozwe ukurikije umurongo uhoraho hamwe na voltage ihoraho, kandi ntishobora kuzuza byimazeyo ibisabwa byihuta byihuta byihuta, kuburyo bidashobora gukoreshwa nka moteri ihinduranya.

Itandukaniro riri hagati yimoteri ihinduka na moteri isanzwe bigaragarira cyane mubice bibiri bikurikira:

Ubwa mbere, moteri isanzwe irashobora gukora gusa umwanya muremure hafi yumurongo wamashanyarazi, mugihe moteri ihindagurika irashobora gukora igihe kinini mubihe biri hejuru cyane cyangwa munsi yumuriro w'amashanyarazi;kurugero, ingufu z'amashanyarazi mugihugu cyacu ni 50Hz., niba moteri isanzwe iri kuri 5Hz igihe kinini, bizananirana vuba cyangwa byangiritse;no kugaragara kwa moteri ihindagurika ikemura iki kibazo cya moteri isanzwe;

Icya kabiri, sisitemu yo gukonjesha moteri isanzwe hamwe na moteri ihindagurika ya moteri iratandukanye.Sisitemu yo gukonjesha moteri isanzwe ifitanye isano rya hafi n'umuvuduko wo kuzunguruka.Muyandi magambo, umuvuduko ukabije moteri izunguruka, nuburyo bwiza bwo gukonjesha, kandi buhoro buhoro moteri izunguruka, niko ingaruka zo gukonjesha ari nziza, mugihe moteri ihindagurika ya moteri idafite iki kibazo.

Nyuma yo kongeramo imirongo ihinduranya kuri moteri isanzwe, ibikorwa byo guhindura inshuro birashobora kugerwaho, ariko ntabwo moteri ihinduranya.Niba ikora munsi yigihe kitari amashanyarazi mugihe kirekire, moteri irashobora kwangirika.

01 Ingaruka zihinduranya kuri moteri ahanini mubikorwa no kuzamuka kwubushyuhe bwa moteri

Inverter irashobora kubyara urwego rutandukanye rwumubyigano wa voltage hamwe numuyoboro mugihe gikora, kugirango moteri ikore munsi yumubyigano utari sinusoidal numuyoboro., icy'ingenzi ni igihombo cy'umuringa wa rotor, ibi bihombo bizatuma moteri yongerwaho ubushyuhe, igabanye imikorere, igabanye ingufu zisohoka, kandi izamuka ryubushyuhe bwa moteri isanzwe ryiyongera 10% -20%.

02 Imbaraga zo gukumira moteri

Inshuro zitwara inshuro zihinduranya zingana kuva ku bihumbi byinshi kugeza kuri kilohertz zirenga icumi, ku buryo stator ihinduranya moteri igomba kwihanganira umuvuduko ukabije w’umuvuduko ukabije, ibyo bikaba bihwanye no gushyira ingufu za moteri ihanitse kuri moteri, bigatuma u guhinduranya hagati ya moteri kwihanganira ikizamini gikomeye..

03 Urusaku rwa electromagnetic urusaku hamwe no kunyeganyega

Iyo moteri isanzwe ikoreshwa numuyoboro uhinduranya, kunyeganyega n urusaku biterwa na electronique, imashini, guhumeka nibindi bintu bizagenda bigorana.Ubwuzuzanye bukubiye mumashanyarazi ahindagurika itanga imbaraga zibangamira umwanya wihariye uhuza igice cya electromagnetic igice cya moteri kugirango habeho imbaraga zitandukanye zo gukurura amashanyarazi, bityo urusaku rwiyongere.Bitewe numurongo mugari wa moteri hamwe nubwinshi bwikurikiranya ryihuta ryumuvuduko, biragoye kumirongo yumurongo wamashanyarazi atandukanye kugirango wirinde guhindagurika kwa kamere ya buri munyamuryango wa moteri.

04 Ibibazo bikonje kuri rpm nkeya

Iyo inshuro zitanga amashanyarazi ari nke, igihombo cyatewe nubwumvikane buke murwego rwo gutanga amashanyarazi ni kinini;icya kabiri, iyo umuvuduko wa moteri ugabanutse, umuvuduko ukonje wumwuka ugabanuka ugereranije na cube yumuvuduko, bigatuma ubushyuhe bwa moteri butagabanuka kandi ubushyuhe bukazamuka cyane.kwiyongera, biragoye kugera kumurongo uhoraho.

05 Urebye uko byavuzwe haruguru, moteri ihinduranya moteri ikoresha igishushanyo gikurikira

Mugabanye stator hamwe na rotor irwanya bishoboka kandi ugabanye gutakaza umuringa wumuraba wibanze kugirango wongere igihombo cyumuringa uterwa nubwumvikane buke.

Umwanya nyamukuru wa magneti ntabwo wuzuye, kimwe nukuzirikana ko guhuza kwinshi bizarushaho kwiyongera kwuzuzanya rwumuzunguruko, naho ubundi nukuzirikana ko ingufu ziva mumashanyarazi zishobora kwiyongera muburyo bukwiye kugirango hongerwe umuriro mwinshi muke inshuro.

Igishushanyo mbonera kigamije ahanini kuzamura urwego;ibibazo byo kunyeganyega n urusaku rwa moteri birasuzumwa neza;uburyo bwo gukonjesha bukoresha gukonjesha ikirere ku gahato, ni ukuvuga, umuyaga nyamukuru ukonjesha moteri ukoresha uburyo bwigenga bwo gutwara ibinyabiziga, kandi imikorere yumuyaga ukonjesha ku gahato ni ukureba ko moteri ikora ku muvuduko muke.gukonja.

Igiceri cyagabanije ubushobozi bwa moteri ihindagurika ya moteri ni ntoya, kandi kurwanya urupapuro rwicyuma cya silicon nini, kuburyo imbaraga za puls nyinshi zifite moteri ari nto, kandi ingaruka zo gushungura inductance ya moteri nibyiza.

Moteri zisanzwe, ni ukuvuga moteri yumurongo wa moteri, gusa dukeneye gusuzuma inzira yo gutangira nuburyo ibintu byakazi byingingo imwe yumurongo wamashanyarazi (nimero rusange: guhuza amashanyarazi), hanyuma ugashushanya moteri;mugihe moteri ihindagurika ya moteri ikeneye gusuzuma inzira yo gutangira nuburyo akazi gakorwa k'ingingo zose murwego rwo guhinduranya inshuro, hanyuma ugashushanya moteri.

Kugirango uhuze nubugari bwa PWM bwahinduwe na analog sinusoidal ihinduranya ibyasohotse na inverter, ikubiyemo ibintu byinshi bihuza, imikorere ya moteri yihariye yakozwe na moteri irashobora kumvikana mubyukuri nka reaction na moteri isanzwe.

01 Itandukaniro hagati ya moteri isanzwe na variable ya moteri yimiterere

1. Ibisabwa birenze urugero

Mubisanzwe, urwego rwimikorere ya moteri ihinduranya moteri ni F cyangwa irenga, kandi kubutaka bwubutaka hamwe nimbaraga zo guhinduranya impinduka bigomba gushimangirwa, cyane cyane ubushobozi bwokwirinda kwihanganira imbaraga za impulse.

2. Kunyeganyega hamwe n urusaku rwibisabwa na moteri ihinduka inshuro nyinshi

Moteri ihinduranya inshuro igomba gutekereza cyane kuburemere bwibigize moteri na byose, kandi ikagerageza kongera inshuro zayo kugirango wirinde kumvikana na buri muhengeri.

3. Uburyo bwo gukonjesha moteri ihindagurika ya moteri iratandukanye

Moteri ihinduranya moteri muri rusange ifata gukonjesha guhumeka, ni ukuvuga umuyaga nyamukuru ukonjesha moteri utwarwa na moteri yigenga.

4. Ibisabwa bitandukanye mu ngamba zo kurinda

Hagomba gufatwa ingamba zo gukumira izimoteri zihindagurika zifite ubushobozi burenze 160kW.Impamvu nyamukuru nuko byoroshye kubyara sisitemu ya magnetiki idasanzwe, kandi ikanatanga amashanyarazi.Iyo imiyoboro ikorwa nibindi bikoresho byinshi byihuta bikorana, umuyoboro wa shaft uziyongera cyane, bikaviramo kwangirika, bityo hafatwa ingamba zo gukumira.Kuri moteri ihoraho yingufu za moteri, mugihe umuvuduko urenze 3000 / min, amavuta adasanzwe hamwe nubushyuhe bwo hejuru agomba gukoreshwa kugirango yishyure ubushyuhe bwikigereranyo.

5. Sisitemu zitandukanye zo gukonjesha

Impinduka zikoreshwa na moteri ikonjesha ikoreshwa nimbaraga zitanga amashanyarazi yigenga kugirango ikomeze gukonjesha.

02 Itandukaniro hagati ya moteri isanzwe na variable ya moteri yubushakashatsi

1. Igishushanyo cya Electromagnetic

Kuri moteri isanzwe idahwitse, imikorere yingenzi yibikorwa bisuzumwa mubishushanyo nubushobozi burenze urugero, gutangira imikorere, gukora neza nimbaraga.Moteri ihindagurika ya moteri, kubera ko kunyerera bigereranywa ningaruka zingufu zamashanyarazi, birashobora gutangira muburyo butaziguye mugihe kunyerera bigoye hafi ya 1. Kubwibyo, ubushobozi burenze urugero nibikorwa byo gutangira ntibikenewe ko bitekerezwa cyane, ariko urufunguzo ikibazo kigomba gukemurwa nuburyo bwo kunoza moteri.Guhuza n'imihindagurikire y'amashanyarazi atari sinusoidal.

2. Igishushanyo mbonera

Mugihe cyo gutegura imiterere, birakenewe kandi gutekereza ku ngaruka ziterwa n’amashanyarazi adafite sinusoidal ku miterere y’imyororokere, kunyeganyega, n’uburyo bwo gukonjesha urusaku rwa moteri ihindagurika.
