Servo drives yog ib qho tseem ceeb ntawm kev tswj cov lus tsa suab niaj hnub thiab tau siv dav hauv cov khoom siv automation xws li cov neeg hlau muaj thiab CNC machining chaw. Tshwj xeeb, servo drives siv los tswj AC cov hlau nplaum ruaj khov synchronous motors tau dhau los ua kev tshawb fawb hotspot ob qho tib si hauv tsev thiab thoob ntiaj teb. Tam sim no, AC servo tsav tsim feem ntau siv peb - voj tswj algorithm raws li vector tswj rau tam sim no, ceev, thiab txoj hauj lwm. Kev tsim kom zoo ntawm lub voj nrawm hauv qhov algorithm no ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm tag nrho cov servo tswj qhov system, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm kev tswj ceev.
Nyob rau hauv lub voj voog ceev ntawm lub servo tsav, qhov tseeb ntawm qhov tseeb - lub sij hawm lub cev muaj zog rotor ceev ntsuas yog qhov tseem ceeb rau kev txhim kho cov yam ntxwv zoo li qub thiab zoo li qub ntawm lub voj voog tswj ceev. Txhawm rau ntsuas qhov ntsuas qhov tseeb thiab tus nqi tsim nyog, cov khoom siv hluav taws xob sib txuas ntxiv feem ntau yog siv los ua cov ntsuas ntsuas ceev, thiab cov kev ntsuas uas siv feem ntau yog M / T txoj kev. Txawm hais tias txoj kev M / T muaj qee qhov kev ntsuas qhov tseeb thiab qhov ntsuas dav dav, nws muaj qhov tsis zoo, feem ntau suav nrog: 1) tsawg kawg ib qho kev ua tiav encoder mem tes yuav tsum tau kuaj pom nyob rau hauv lub voj voog ntsuas ceev, txwv qhov ntsuas qis tshaj plaws; 2) Nws yog ib qho nyuaj rau kev nruj me ntsis synchronize ob lub kaw lus tswj timers siv rau kev ntsuas ceev, ua rau nws tsis tuaj yeem lav qhov ntsuas qhov tseeb nyob rau hauv cov xwm txheej nrog kev hloov pauv loj. Yog li ntawd, ib txwm ceev lub voj tsim siv txoj kev ntsuas ceev no tawm tsam los txhim kho kev ceev thiab tswj kev ua haujlwm ntawm servo tsav.
