Servo System Kev Ua Hauj Lwm Thiab Qib Kawm
Tam sim no, nrog kev nruam technology, AC servo motor technology nrog nws zoo heev tus nqi-zoo, thiab maj mam hloov DC lub cav ua lub zog ntawm servo system.The kom paub meej ntawm AC servo system technology kuj ua rau lub khw nthuav dav sai thiab ua ib qho ntawm cov kev txhawb nqa ntawm cov khoom siv hluav taws xob.
Lub Tuam Tsev Loj
1, nrog lub hwj chim ua hluav taws xob khiav cov teeb liab los tswj lub hwj chim siab;
2, thaum tsis muaj kev sib txuas ntawm qhov sib txuas, cov tswv yim tswj kev tswj cov chaw taws teeb nyob hauv cov qhov hluav taws xob, kom ua tiav ntev ntau yam kev sib tshooj sib txuas;
3, ua kom muaj kev tawm dagzog tawm raws cov hluavtaws xob, xws li cov ntaub ntawv thiab qhia txog cov twj paj nruag.
Kev Ntaus Ntaus
Los ntawm cov khoom ntawm lub tshuab, muaj cov hluav taws xob servo system, hydraulic servo system thiab cov hluav taws xob - hydraulic servo system thiab hluav taws xob - hluav taws xob servo system;
Txij ntawm lub zog ntawm lub tso zis tso tawm, muaj kev pab ceev ceev los yog acceleration servo thiab chaw servo system;
Los ntawm lub cev uas muaj kev tivthaiv yam ntxwv thiab cov teebmeem ntawm tus cwj pwm, muaj cov tshuab analog thiab digital
servo system;
Los ntawm cov yam ntxwv ntawm tus qauv, nws muaj ib qhov kev pabcuam, cov kev pabcuam zov me nyuam thiab qhib-loop servo system, kaw-kev pabcuam kaw haujlwm.
Servo system raws li nws cov tsav tsheb, muaj cov kev pabcuam stepper servo, DC lub cev (xa mus rau DC motor) servo system,
AC tsav (raug xa mus rau AC motor) servo system.Raws li hom kev tswj, muaj qhib-voj servo qhov system, kaw-lub vev xaib servo system thiab ib qhov-kaw-voj servo system.In qhov tseeb, CNC system yog tseem muab faib ua qhib- voj, kaw-loop thiab ib nrab-kaw-voj peb hom, uas yog hais txog peb hom kev pab servo.
1, Qhib-loop system
Tus qhib voj voog kaw lus muaj cov tsav tsheb, actuators thiab lub cuab yeej siv lub cav.Commonly siv actuator yog lub cav tsav, uas feem ntau hu ua stepper lub cev raws li qhov kev pib ntawm kev qhib voj voog rau cov kev pabcuam stepper servo.Nyob rau hauv lub cev, yog tias nws high-power drive, nrog stepper motor raws li kev siv ntawm Cheebtsam. Lub ntsiab haujlwm ntawm kev tsav Circuit Court yog hloov cov lus siv pulse rau hauv lub teeb liab uas yuav tsum tau tsav cov actuator.
2, kaw lub voj voog system
Kaw qhov kev voj voog yog tsim los ntawm cov neeg ua haujlwm, kev tshawb nrhiav, kev sib piv, kev tsav tsheb thiab cov khoom hauv tshuab. .Ntau lub kaw lus-voj kaw, nrhiav kom paub qhov tseeb ntawm qhov chaw ntawm lub tshuab hloov khoom thiab hloov ua hluav taws xob cov kev sib piv rau cov kev sib piv. Nrhiav kom pom cov tswv yim ua teb, cov khoom ua kom induction , cov khoom sib nqus, sib nqus cov sob thiab daim encoder. servo system txhaj ntawm qhov kev ntsuas ntawm lub pob ntsia hlau hu ua lub voj voos khib ib nrab; lub servo system muaj li ntawm cov khoom ntes uas tau txhim kho rau ntawm lub rooj hu ua kaw lub voj kaw lus.Tsis muaj qhov yuam kev ntawm kev sib tw ntawm lub npas thiab lub rooj, qhov tseeb ntawm qhov kev pab cuam hauv lub vojvoog yog ib qho qis tshaj qhov kaw lub voj kev pabcuam system.Qhov lub luag haujlwm ntawm qhov sib piv txuas yog los sib piv cov teebmeem hais kom ua thiab lub tswv yim tawm tswv yim, qhov txawv ntawm ob qhov kev ua yuam kev li nram qab no ntawm servo system, tsav circuit thiab tswj actuator tsav lub rooj mus ntxiv rau txav mus txog rau thaum tus ua raws li cov lus yuam kev xoom.Raws li daim ntawv ntawm qhov sib piv ntawm qhov sib piv thiab lub tswv yim nrhiav tau hom, kaw lub voj voog (semi closed loop) system tau muab faib ua cov mem tes sib piv servo system, theem sib piv servo system thiab amplitude sib piv servo system.
Raws li qhov sib txuas txuas tawm cov teeb liab yog cov qaug zog, tsis tuaj yeem tsav cov actuator, nws yog ib qho tsim nyog yuav tsum ua kom loj dua, tus tsav hluav taws xob yog teem rau lub hom phiaj no.
Cov kev ua ntawm cov actuator yog hloov cov teeb meem hluav taws xob uas sawv cev rau kev xa tawm mus rau ib qho chaw xaav raws li kev teeb liab, uas yog qhov teeb meem nram qab no los ntawm kev sib piv txuas.Puas siv cov actuators yog DC dav tsav tsheb, AC motor thiab kom .Tus actuator yog ib qho tseem ceeb ntawm qhov kev pabcuam, thiab cov tsav hluav taws xob sib txawv yog nyob ntawm tus actuator.
