UCanwin yiNkampani yeNkampani yoTshintsho lwaMandla kunye noMvelisi woMbane woMbane
Igama elithi servo livela kwigama lesiGrike elithetha ikhoboka."Servo motor" ingaba iqondwa njengemoto ethobela ngokupheleleyo umyalelo wolawulo uphawu.Xa isignali yokulawula ithunyelwa, i-rotor ngokukhawuleza iqengqeleka.Xa uphawu lolawulo luyanyamalala, i-rotor inokuyeka ukusebenza ngokukhawuleza.
Igama elithi servo livela kwigama lesiGrike elithetha ikhoboka."I-Servo motor" inokuqondwa njengemoto ethobela ngokupheleleyo umyalelo wesignali yokulawula.Xa umqondiso wokulawula uthunyelwa, i-rotor ngokukhawuleza iyaqengqeleka.Xa uphawu lokulawula luphela, Irotor inokuyeka ukubaleka kwangoko.
I-Servo motor yinjini encinci esetyenziswa njengesixhobo solawulo kwisixhobo solawulo oluzenzekelayo. Umsebenzi wayo kukuguqula izibonakaliso zombane kwi-angular displacement okanye i-angular velocity ye-shaft ejikelezayo.
I-Servo motor yahlulwe yaba yi-ac servo kunye ne-dc servo iindidi ezimbini
Isakhiwo esisisiseko se-ac servo motor sifana ne-ac induction motor.Kukho i-excitation windings ezimbini ze-Wf kunye nokulawula i-WcoWf kunye ne-displacement yendawo ye-90 ° kwi-stator, exhunywe nge-voltage ye-ac rhoqo. Injongo yokulawula ukusebenza kweemoto iphunyezwa ngokusebenzisa utshintsho lwe-ac voltage okanye isigaba esisetyenzisiweyo kwi-Wc.Ac servo motor ineempawu zokusebenza kakuhle, ukulawulwa kakuhle, ukuphendula ngokukhawuleza, ukuhamba okuphezulu kunye nesalathisi esingqongqo se-nonlinear yeempawu zoomatshini kunye neempawu zokulungelelanisa ( ngaphantsi kwe-10% ~ 15% kwaye ngaphantsi kwe-15% ~ 25%, ngokulandelelanayo).
Ulwakhiwo olusisiseko lwe-dc servo motor lufana nelo dc motor.Isantya seMotor n = E/K1j = (Ua - IaRa)/K1j, udidi lwe-E lwe-armature counter force electromotive force, i-K iyaguquguquka, i-j per pole flux, Ua , i-Ia yombane we-armature ye-armature yangoku kunye ne-armature yangoku, i-Ra njengokumelana nezixhobo, ukutshintsha i-Ua okanye i-phi, inokulawula isantya seengcinga zombane ze-servo ye-dc, kodwa ngokubanzi yamkele indlela yokulawula i-armature voltage, ingcamango yombane Umazibuthe osisigxina i-dc servo, i-excitation winding ithatyathelwa indawo yimagnethi esisigxina, imagnethi eguquguqukayo phi ihlala njalo.Dc servo motor inomgaqo olungileyo womgca kunye nokuphendula kwexesha elikhawulezayo.
Izinto ezilungileyo kunye nokungalunganga kwe-dc servo motor
Izinto eziluncedo: ulawulo oluchanekileyo lwesantya, iimpawu zesantya setorque zinzima kakhulu, umgaqo olula wolawulo, kulula ukuyisebenzisa, ixabiso eliphantsi.
Izinto ezingeloncedo: ukubuyisela umva ibrashi, ukunciphisa isantya, ukuxhathisa okongeziweyo, amasuntswana abrasive (akukho thuli kunye nemekobume eqhumayo ayifanelekanga)
Izinto ezilungileyo kunye nokungalunganga kwe-ac servo motor
Amandla: Iimpawu zokulawula isantya esilungileyo, kulo lonke uluhlu lwezantya zinokuqonda ulawulo olugudileyo, phantse akukho oscillation, ngaphezulu kwe-90% yokusebenza okuphezulu, umkhuhlane omncinci, ukulawulwa kwesantya esiphezulu, ukuchaneka kokulawula indawo echanekileyo (kuxhomekeke kwi-encoder), ilinganiswe. Indawo yokusebenza, inokuqonda i-torque engaguqukiyo, umzuzu we-inertia uphantsi, ingxolo ephantsi, akukho kunxitywa kwebrashi, ukugcinwa kwasimahla (kungathuli, indawo eqhumayo)
Ukungalungi: ulawulo lunzima ngakumbi, iiparitha zomqhubi kufuneka zilungiswe kwindawo ukuze zinqume iiparamitha ze-PID, kwaye i-wiring eninzi iyadingeka.
I-Dc servo motor yahlulwe yaba yibrashi kunye ne-brushless motor.
Iindleko ze-brush motor ziphantsi, isakhiwo esilula, i-torque yokuqala inkulu, uluhlu lwesantya lubanzi, ulawulo lulula, ludinga ukugcinwa, kodwa gcina inzuzo (ye-carbon brush), isizukulwana sokuphazamiseka kwe-electromagnetic, ukusetyenziswa kwendalo kuneemfuno. , edla ngokusetyenziselwa uvakalelo lweendleko zeshishini eliqhelekileyo kunye neziganeko zasekuhlaleni.
I-Brushless motor enobunzima obuncinci ukukhanya, isiphumo esikhulu sokuphendula ngokukhawuleza, isantya esiphezulu se-inertia encinci, i-torque ayilungelelanisi ukuqengqeleka, ulawulo oluntsokothileyo, ubukrelekrele, ukutshintshiselana ngesigaba se-elektroniki, i-square wave okanye i-sine wave phase exchange, ukugcinwa kwemoto simahla, ukonga amandla ngokufanelekileyo, i-electromagnetic. Ukusasazeka kwemitha encinci, ubushushu obuphantsi bukhula ubomi obude, bulungele iindawo ezahlukeneyo.
I-Ac servo motor ikwayi-brushless motor, yahlulwe yaba yi-synchronous kunye ne-asynchronous motor, ulawulo lwentshukumo lwangoku lusetyenziswa ngokubanzi kwi-synchronous motor, uluhlu lwamandla ayo, amandla anokuba makhulu kakhulu, inertia enkulu, esona santya siphezulu sisezantsi, isantya kunye nokonyuka kwamandla. kunye nokuncipha okufanayo, okufanelekile kwiziganeko zokusebenza ezinesantya esisezantsi
Ngaphakathi kwi-servo motor rotor yimagnethi esisigxina, ulawulo lombane lwesigaba sesithathu U / V / W lwenza intsimi ye-electromagnetic, phantsi kwesenzo se-rotor ejikelezayo kule ndawo, ngexesha elifanayo, i-motor ene-encoder feedback signal to i-drive, ixabiso lengxelo xa kuthelekiswa nethagethi, ukulungelelanisa i-Angle ye-rotor rolling, ukuchaneka kwe-servo motor kunqunywe ngokuchaneka kwe-encoder (inombolo yomgca).
Yintoni injini ye-servo? Zingaphi iindidi ezikhoyo? Ziziphi iimpawu zomsebenzi?
Impendulo: Ingcamango yombane ye-servo eyaziwa ngokuba yingcinga yombane yesigqeba, kwinkqubo yokulawula ngokuzenzekelayo ukusetyenziswa njengesixhobo sokulawula, isignali yombane efunyenweyo kwingcamango yombane ye-axis ye-angular displacement okanye i-angular speed output.
