Umushoferi wa Servo,bizwi kandi nka "servo mugenzuzi" cyangwa "servo amplifier", ni ubwoko bwumugenzuzi ukoreshwa mugucunga moteri ya servo. Imikorere yacyo isa niy'umuhinduzi uhinduranya ukora kuri moteri isanzwe ya AC, kandi ni igice cya sisitemu ya servo. Mubisanzwe, moteri ya servo igenzurwa muburyo butatu: umwanya, umuvuduko, hamwe na torque kugirango ugere kumwanya-wuzuye wa sisitemu yo kohereza.
1 、 Gutondekanya moteri ya servo
Igabanijwemo ibyiciro bibiri: moteri ya DC na AC servo, moteri ya AC servo irongera igabanywamo moteri ya servo idahwitse hamwe na moteri ya servo. Kugeza ubu, sisitemu ya AC isimbuza buhoro buhoro sisitemu ya DC. Ugereranije na sisitemu ya DC, moteri ya AC servo ifite ibyiza nko kwizerwa cyane, gukwirakwiza ubushyuhe bwiza, umwanya muto wa inertia, hamwe nubushobozi bwo gukora mubihe byinshi bya voltage. Bitewe no kubura guswera hamwe nibikoresho byo kuyobora, sisitemu ya seriveri ya AC yigenga nayo yahindutse sisitemu ya servo idafite brush. Moteri ikoreshwa muri yo ni brushless cage idafite moteri na moteri ihoraho ya moteri.
1. Moteri ya DC servo igabanijwemo moteri yogejwe kandi idafite brush
Motors Moteri ya Brushless ifite igiciro gito, imiterere yoroshye, nini nini yo gutangira, umuvuduko mugari wo kugenzura, kugenzura byoroshye, kandi bisaba kubungabungwa. Nyamara, biroroshye kubungabunga (gusimbuza karuboni ya karubone), kubyara amashanyarazi, kandi bifite ibisabwa mubidukikije. Mubisanzwe bikoreshwa mugiciro cyoroshye inganda zisanzwe hamwe nabenegihugu;
Motors Moteri ya Brushless ifite ubunini buto, uburemere bworoshye, ibisohoka binini, igisubizo cyihuse, umuvuduko mwinshi, inertia ntoya, itara rihamye hamwe no kuzunguruka neza, kugenzura ibintu bigoye, ubwenge, uburyo bworoshye bwo guhinduranya ibintu, birashobora kuba umurongo wa kare cyangwa kugabanuka kwa sine, kubungabunga kubuntu, gukora neza no kuzigama ingufu, imirasire ya electromagnetique nkeya, kuzamuka kwubushyuhe buke, kuramba kumurimo muremure, kandi birakwiriye ibidukikije bitandukanye.
2 、 Ibiranga ubwoko butandukanye bwa moteri ya servo
1. Ibyiza nibibi bya moteri ya DC servo
Ibyiza: Igenzura ryihuse, umuvuduko ukabije wumuvuduko, ihame ryoroshye ryo kugenzura, gukoresha neza, nigiciro cyiza.
Ibibi: Gukata amashanyarazi, kugabanya umuvuduko, kongera imbaraga, kubyara uduce duto two kwambara (ntibikwiriye kuba umukungugu kandi biturika)
2. Ibyiza n'ibibi byaMoteri ya AC servo
Ibyiza: Ibiranga umuvuduko mwiza wo kugenzura, kugenzura neza birashobora kugerwaho murwego rwose rwihuta, hafi nta guhungabana, gukora neza hejuru ya 90%, kubyara ubushyuhe buke, kugenzura umuvuduko mwinshi, kugenzura imyanya ihanitse (bitewe nukuri kuri kodegisi), Irashobora kugera kumuriro uhoraho mukarere kagenwe, inertia nkeya, urusaku ruke, nta kwambara brush, kubungabunga kubusa (bikwiranye nubutaka butagira ivumbi nibidukikije).
Ibibi: Igenzura riragoye, kandi ibipimo bya shoferi bigomba guhindurwa kurubuga kugirango umenye ibipimo bya PID, bisaba insinga nyinshi.
Kugeza ubu, imiyoboro nyamukuru ya servo ikoresha ibyuma byerekana ibimenyetso bya digitale (DSP) nkibyingenzi bigenzura, bishobora kugera kuri algorithm igoye, kugenzura, guhuza imiyoboro, hamwe nubwenge. Ibikoresho byingufu muri rusange bikoresha ibinyabiziga bitwara ibinyabiziga bifite imbaraga zubwenge (IPM) nkibyingenzi. IPM ihuza imiyoboro yo gutwara imbere kandi ifite kandi inzira yo gutahura no gukingira amakosa yo gukabya gukabya, kurenza urugero, gushyuha cyane, munsi ya voltage, n'ibindi. Igice cyo gutwara amashanyarazi kibanza gukosora ibyinjijwemo ibyiciro bitatu cyangwa bigakoresha ingufu binyuze mubice bitatu byuzuye byuzuye ikiraro gikosora kugirango ubone imbaraga za DC. Nyuma yo gukosorwa, ibyiciro bitatu cyangwa imbaraga zikoreshwa mugutwara ibyiciro bitatu bihoraho bya magnet bihoraho bihuza AC servo moteri ikoresheje ibyiciro bitatu bya sine PWM voltage isoko ya inverter kugirango ihindurwe inshuro. Inzira yose yumuriro wumuriro urashobora gusobanurwa gusa nkibikorwa bya AC-DC-AC. Inzira nyamukuru ya topologiya yumurongo wogukosora (AC-DC) nicyiciro cyibice bitatu byuzuye ikiraro kitagenzuwe neza.
3 、Sisitemu ya wiring igishushanyo
1. Amashanyarazi
Disiki ya servo ikubiyemo cyane cyane kugenzura imiyoboro yumuriro, kugenzura amashanyarazi nyamukuru, gutanga amashanyarazi asohoka, kwinjiza CN1, kugenzura kodegisi CN2, no guhuza CN3. Amashanyarazi agenzura amashanyarazi ni icyiciro kimwe cyo gutanga amashanyarazi, kandi imbaraga zinjiza zishobora kuba icyiciro kimwe cyangwa ibyiciro bitatu, ariko bigomba kuba 220V. Ibi bivuze ko mugihe ibyiciro bitatu byinjijwe byakoreshejwe, amashanyarazi atatu yicyiciro agomba guhuzwa binyuze muri transformateur. Kubashoferi bafite imbaraga nke, birashobora gutwarwa muburyo bumwe, kandi uburyo bumwe bwo guhuza bigomba guhuzwa na R na S. Wibuke kudahuza moteri ya servo isohoka U, V, na W kumashanyarazi nyamukuru, kuko bishobora gutwika umushoferi. Icyambu cya CN1 gikoreshwa cyane cyane muguhuza mudasobwa yo hejuru, itanga ibyinjira, ibisohoka, encoder ABZ ibyiciro bitatu bisohoka, hamwe nibisohoka byerekana ibimenyetso bitandukanye byo gukurikirana.
2. Encoder wiring
Duhereye ku gishushanyo kivuzwe haruguru, urashobora kubona ko twakoresheje 5 gusa muri terefone icyenda, harimo insinga imwe ikingira, insinga ebyiri z'amashanyarazi, hamwe n'ibimenyetso bibiri by'itumanaho (+ -), bisa n'insinga za kodegisi yacu isanzwe.
3. Icyambu cy'itumanaho
Umushoferi yahujwe na mudasobwa yo hejuru nka PLC na HMI binyuze ku cyambu cya CN3, kandi igenzurwa binyuzeItumanaho rya MODBUS. RS232 na RS485 birashobora gukoreshwa mugutumanaho.
