Ihame ryakazi rya moteri ya AC servo:
Iyo moteri ya AC servo idafite voltage igenzura, habaho gusa imbaraga za rukuruzi zitera imbaraga zatewe no kwishima kuzunguruka muri stator, kandi rotor irahagarara.Iyo hari voltage igenzura, umurima wa magneti uzunguruka ubyara muri stator, hanyuma rotor ikazenguruka yerekeza kumyerekezo yumuzingi wa magneti.Iyo umutwaro uhoraho, umuvuduko wa moteri uhinduka hamwe nubunini bwa voltage igenzura.Iyo icyiciro cyo kugenzura voltage kinyuranye, AC servo Moteri izahindukira.Nubwo ihame ryakazi rya moteri ya AC servo risa nkiryigabanyijemo icyiciro kimwe icyiciro kimwe cya moteri idahwitse, rotor irwanya iyambere nini cyane kuruta iyanyuma.Kubwibyo, ugereranije na moteri imwe idafite moteri, moteri ya servo ifite ibintu bitatu byingenzi:
1. Itara rinini ryo gutangira
Bitewe no kurwanya rotor nini, umurongo wacyo uranga umurongo werekana kumurongo wa 1 mu gishushanyo cya 3, bigaragara ko itandukanye na torque iranga umurongo wa 2 ya moteri isanzwe idafite imbaraga.Irashobora gukora igipimo gikomeye cyo kunyerera S0> 1, idakora gusa itara riranga (imiterere ya mashini) ryegereye umurongo, ariko kandi rifite itara rinini ryo gutangira.Kubwibyo, iyo stator ifite igenzura ryumubyigano, rotor irazunguruka ako kanya, ifite ibiranga gutangira byihuse no kumva cyane.
2. Urwego rwagutse
3. Nta kintu cyo kuzunguruka
Kuri moteri ya servo mubikorwa bisanzwe, mugihe cyose voltage yo kugenzura yatakaye, moteri izahita ikora.Iyo moteri ya servo itakaje imbaraga zo kugenzura, iba iri murwego rumwe rukora.Bitewe nokurwanya kwinshi kwa rotor, ibintu bibiri biranga torque (T1-S1, T2-S2 umurongo) byakozwe numurima wa magnetiki uzunguruka uzunguruka mubyerekezo bitandukanye muri stator hamwe nigikorwa cya rotor) hamwe nibiranga torque (TS) umurongo) Imbaraga zisohoka moteri ya AC servo muri rusange ni 0.1-100W.Iyo amashanyarazi ari 50Hz, voltage ni 36V, 110V, 220, 380V;iyo amashanyarazi ari 400Hz, voltage ni 20V, 26V, 36V, 115V nibindi.Moteri ya AC servo ikora neza hamwe n urusaku ruke.Ariko kugenzura biranga ntabwo ari umurongo, kandi kubera ko rotor irwanya nini, igihombo ni kinini, kandi imikorere ikaba mike, ugereranije na moteri ya DC servo ifite ubushobozi bumwe, ni nini kandi iremereye, kuburyo ikwiye gusa kuri sisitemu ntoya yo kugenzura ingufu za 0.5-100W.
Icya kabiri, itandukaniro hagati ya moteri ya AC servo na moteri ya DC servo:
Moteri ya DC servo igabanijwemo moteri yogejwe kandi idafite brush.Moteri yogejwe ni mike mugiciro, yoroshye mumiterere, nini mugutangira torque, mugari murwego rwo kugenzura umuvuduko, byoroshye kugenzura, kandi bisaba kubungabungwa, ariko biroroshye kubungabunga (gusimbuza karuboni ya karubone), kubyara amashanyarazi, kandi bifite ibisabwa kubisabwa ibidukikije.Kubwibyo, irashobora gukoreshwa mubikorwa rusange byinganda nimbonezamubano byunvikana kubiciro.Moteri idafite amashanyarazi ni ntoya mubunini, urumuri muburemere, nini mubisohoka, byihuse mubisubizo, hejuru mumuvuduko, ntoya muri inertia, yoroshye mukuzunguruka kandi ihagaze neza.Igenzura riragoye, kandi biroroshye kumenya ubwenge.Uburyo bwa elegitoronike bwo guhindura ibintu biroroshye, kandi birashobora kuba kwaduka kwaduka cyangwa kugabanuka kwa sine.Moteri ntishobora kubungabungwa, ifite imikorere myiza, ubushyuhe buke bwo gukora, imirasire ya electromagnetique, ubuzima burebure, kandi irashobora gukoreshwa mubidukikije.
Moteri ya AC servo igabanijwemo moteri ihuza kandi idahwitse.Kugeza ubu, moteri ya syncron ikoreshwa muri rusange kugenzura ibikorwa.Ingufu zayo nini kandi irashobora kugera ku mbaraga nini.Inertia nini, umuvuduko ntarengwa wo kuzunguruka, kandi igabanuka vuba uko imbaraga ziyongera.Kubwibyo, birakwiriye kubisabwa bigenda neza kumuvuduko muke.
Rotor imbere ya moteri ya servo ni rukuruzi ihoraho.Amashanyarazi U / V / W ibyiciro bitatu bigenzurwa numushoferi akora umurima wa electroniki.Rotor irazenguruka munsi yiki gikorwa cyumurima wa magneti.Muri icyo gihe, kodegisi ya moteri igarura ibimenyetso kuri shoferi.Indangagaciro zigereranijwe no guhindura inguni rotor ihindukirira.Ubusobanuro bwa moteri ya servo biterwa nukuri (umubare wumurongo) wa kodegisi.
Hamwe nogutezimbere kwiterambere ryimikorere yinganda, icyifuzo cya software ikora nibikoresho byuma bikomeza kuba byinshi.Muri byo, isoko ry’imashini zikoreshwa mu nganda zo mu gihugu ryagiye ryiyongera gahoro gahoro, kandi igihugu cyanjye cyabaye isoko rikenewe cyane ku isi.Mugihe kimwe, itwara isoko ryisoko rya sisitemu ya servo.Kugeza ubu, moteri ya AC na DC servo ifite moteri yo hejuru cyane, torque nini na inertia nkeya ikoreshwa cyane muri robo yinganda.Izindi moteri, nka moteri ya AC servo na moteri yintambwe, nazo zizakoreshwa muri robo yinganda ukurikije ibisabwa bitandukanye.
