Makina a servo mwina ndi chowongolera chozungulira kapena chowongolera chowongolera chomwe chimayang'anira kuyang'ana, kuyimika, kuthamanga ndi kuthamangitsa chidutswa cha makina.Makina omwe amayendera ma servo motors amagetsi amatha kutsegulidwa ndikuwongoleredwa kudzera pa masensa.Kaya ntchito imadalira torque kapena mtsogolo, mota ya servo nthawi zambiri imakwaniritsa zofunikirazo molondola komanso kudalirika kuposa mitundu ina yamagalimoto.Mwakutero, ma servo motors amawonedwa ngati funde lamtsogolo mu gawo laukadaulo.
Kodi servo motor ndi chiyani poyerekeza ndi ma mota ena?Izi zitha kuyankhidwa bwino poyerekeza makina amagetsi a servo motor ndi mtundu wina wa motor actuator, motor stepper.
Servo motor imakhala ndi mawaya atatu omwe amadziwika kuti Power, Ground and Control pomwe DC motor ndi mawaya awiri omwe amadziwika kuti Mphamvu ndi Ground.
Servo motor ili ndi zinthu zinayi za DC motor, gearing set, control circuit ndi sensor position.DC Motor sikhala ndi msonkhano uliwonse.
Servo motor sizungulira momasuka komanso mosalekeza ngati mota ya DC.Kuzungulira kwake kumangokhala 180⁰ pomwe mota ya DC imazungulira mosalekeza.
Ma Servo motors amagwiritsidwa ntchito m'mikono yamaloboti, miyendo kapena makina owongolera ndi magalimoto oseweretsa.Ma motors a DC amagwiritsidwa ntchito pamafani, mawilo amagalimoto, ndi zina zambiri.
Servo motor imagwiritsidwa ntchito kwambiri pazida zaukadaulo wapamwamba pamafakitale monga ukadaulo wamagetsi.Ndi chipangizo chamagetsi chokhazikika chokha, chomwe chimazungulira mbali za makina ndikuchita bwino kwambiri komanso molondola kwambiri.Shaft yotulutsa ya injini iyi imatha kusunthidwa kukona inayake.Ma servo motors amagwiritsidwa ntchito kwambiri pamagetsi apanyumba, zoseweretsa, magalimoto, ndege, etc.Nkhaniyi ikufotokoza zomwe servo motor, servo motor ikugwira ntchito, mitundu yamagalimoto a servo ndi magwiritsidwe ake.
Servo drive ndi amplifier yapadera yamagetsi yomwe imagwiritsidwa ntchito kupatsa mphamvu ma servomechanisms amagetsi.
Ma servo drive amayang'anira chizindikiritso kuchokera ku servomechanism ndikusintha mosalekeza kuti apatukane ndi zomwe zimayembekezeredwa.
Mu servo system, servo drive kapena servo amplifier imayang'anira kupatsa mphamvu injini ya servo.Kuyendetsa kwa servo ndichinthu chofunikira kwambiri pakuzindikira momwe ma servo amagwirira ntchito.Kuyendetsa kwa Servo kumapereka maubwino angapo pamakina opangira makina, kuphatikiza mawonekedwe apamwamba, kuthamanga, ndi kuwongolera koyenda.
Makina a servo amaphatikiza injini ya servo yogwira ntchito kwambiri yokhala ndi servo amplifier (drive) kuti ikwaniritse malo olondola kwambiri, kuthamanga, kapena kuwongolera ma torque.Sankhani kukula kwadongosolo kutengera mphamvu zamagetsi.Kuti mugwire ntchito kwambiri, sungani inertia mkati mwa 10x ya inertia yamagalimoto.Onjezani zingwe zamagetsi ndi mayankho a dongosolo lonse.
Ma servo drive amalandira chizindikiritso kuchokera ku makina owongolera, amakulitsa chizindikirocho, ndikutumiza magetsi ku servo motor kuti apange kuyenda molingana ndi chizindikiro cha lamulo.Nthawi zambiri, chizindikiro cholamula chimayimira liwiro lomwe mukufuna, koma imathanso kuyimira torque kapena malo omwe mukufuna.Sensa yolumikizidwa ndi servo motor imafotokoza momwe galimotoyo ilili pobwerera ku servo drive.Ma servo drive ndiye amafanizira mawonekedwe enieni agalimoto ndi momwe adalamulidwa.Kenako imasintha mphamvu yamagetsi, ma frequency kapena pulse wide kupita ku mota kuti ikonzekere kupatuka kulikonse kuchokera pagawo lolamulidwa.
Mudongosolo lokonzekera bwino, servo motor imazungulira pa liwiro lomwe limayandikira kwambiri chizindikiro cha liwiro chomwe chikulandiridwa ndi servo drive kuchokera ku dongosolo lowongolera.Magawo angapo, monga kuuma (komwe kumadziwikanso kuti kupindula molingana), kutsitsa (komwe kumadziwikanso kuti phindu lochokera), ndi kupindula kwa mayankho, kungasinthidwe kuti mukwaniritse zomwe mukufuna.Njira yosinthira magawowa imatchedwa performance tuning.
Ngakhale ma servo motors amafunikira kuyendetsa molunjika ku mtundu wamoto kapena mtunduwo, ma drive ambiri akupezeka omwe amagwirizana ndi ma mota osiyanasiyana.
Servo amplifiers ndi mtima wolamulira wa servo system.Ma servo amplifiers amakhala ndi magawo atatu, magetsi, komanso magwiridwe antchito apamwamba onse omwe amakhala mumpanda umodzi.Malupu angapo owongolera amazindikira digito kwathunthu mu controller yaying'ono.
Kulankhula mogwira ntchito, kukulitsa chizindikiro ndizomwe zikuchitika mkati mwa servo drive.Chifukwa chake, chifukwa chake drive nthawi zina imatchedwa servo amplifier.
Makina a servo amaphatikiza injini ya servo yogwira ntchito kwambiri yokhala ndi servo amplifier (drive) kuti ikwaniritse malo olondola kwambiri, kuthamanga, kapena kuwongolera ma torque.Sankhani kukula kwadongosolo kutengera mphamvu zamagetsi.Kuti mugwire ntchito kwambiri, sungani inertia mkati mwa 10x ya inertia yamagalimoto.Onjezani zingwe zamagetsi ndi mayankho a dongosolo lonse.
Inverter yamagetsi, kapena inverter, ndi chipangizo chamagetsi chamagetsi kapena ma circuitry omwe amasintha Direct current (DC) kukhala alternating current (AC).
Magetsi olowera, ma voliyumu otulutsa ndi ma frequency, komanso mphamvu zonse zogwirira ntchito zimatengera kapangidwe kachipangizo kapena ma circuitry.Inverter simapanga mphamvu iliyonse;mphamvu imaperekedwa ndi gwero la DC.
Inverter yamagetsi imatha kukhala yamagetsi kwathunthu kapena ikhoza kukhala yophatikizika yamakina (monga zida zozungulira) ndi zozungulira zamagetsi.Ma static inverters sagwiritsa ntchito magawo osuntha posinthira.
Ma inverters amagetsi amagwiritsidwa ntchito makamaka pamagetsi amagetsi pomwe mafunde apamwamba ndi ma voltages amapezeka;mabwalo omwe amagwira ntchito yofanana pamagetsi amagetsi, omwe nthawi zambiri amakhala ndi mafunde otsika kwambiri komanso ma voltages, amatchedwa oscillators.Madera omwe amagwira ntchito yosiyana, kutembenuza AC kukhala DC, amatchedwa rectifiers.

Programmable logic controller (PLC) ndi kompyuta ya digito yomwe imagwiritsidwa ntchito popanga ma electromechanical process, monga kuwongolera makina pamizere yolumikizira fakitale, kukwera kosangalatsa, kapena zowunikira.Ma PLC amagwiritsidwa ntchito m'mafakitale ndi makina ambiri.Mosiyana ndi makompyuta acholinga chambiri, PLC idapangidwa kuti izikhala ndi zolowetsa zingapo ndi zotulutsa, kuchuluka kwa kutentha, kusatetezedwa ku phokoso lamagetsi, komanso kukana kugwedezeka ndi kukhudzidwa.Mapulogalamu owongolera makina amasungidwa mu kukumbukira kwa batri kapena kosasunthika.A PLC ndi chitsanzo cha dongosolo la nthawi yeniyeni popeza zotsatira zake ziyenera kupangidwa potsatira zomwe zalowetsedwa mkati mwa nthawi yoletsedwa, apo ayi ntchito yosakonzekera idzatuluka.Chithunzi 1 chikuwonetsa chithunzithunzi cha ma PLC.
1. Malo olowetsa omwe amagwiritsidwa ntchito polumikiza zolowetsa za digito kapena za analogi ku PLC zomwe ndi zotumiza kapena kusinthana ndi zina.
2. Momwemonso gawo lotulutsa lomwe limagwiritsidwa ntchito polumikiza zotuluka zakumunda kuchokera ku PLC zomwe dera limatumizirana, magetsi, mavavu owongolera ndi zina.
3. Ma module olankhulirana omwe amagwiritsidwa ntchito posinthanitsa deta pakati pa PLC kupita ku SCADA,HMI kapena PLC ina.
4. Ma module owonjezera omwe amagwiritsidwa ntchito kukulitsa Zolowetsa kapena zotulutsa.
PROGRAMMABLE LOGIC CONTROLLER (PLC) ndi makina owongolera makompyuta omwe nthawi zonse amayang'anira momwe zida zolowera zikuyendera ndikupanga zisankho motengera pulogalamu yomwe idakhazikitsidwa kuti iziwongolera momwe zida zimatulutsira.
Pafupifupi mzere uliwonse wopanga, ntchito yamakina, kapena njira zitha kukulitsidwa kwambiri pogwiritsa ntchito mtundu uwu wowongolera.Komabe, phindu lalikulu pogwiritsira ntchito PLC ndikutha kusintha ndi kubwereza ntchito kapena ndondomeko pamene mukusonkhanitsa ndi kuyankhulana zofunika.
Ubwino wina wa dongosolo la PLC ndikuti ndi modular.Ndiko kuti, mutha kusakaniza ndi kufananiza mitundu ya zida zolowetsa ndi zotulutsa kuti zigwirizane ndi pulogalamu yanu.
