Daim ntawv thov kev pabcuam qiv hauv kev tswj hwm
3.1 Cov kev cai ntawm qhov kev pab cuam ntawm servo motor nyob rau hauv kev tswj zauv
AC servo tsav yog hom brushless lub cev, tab sis nws muab faib ua synchronous thiab asynchronous tshuab. Synchronous lub cev muaj zog ntau dua rau cov lus tsa suab, vim hais tias nws muaj peev xwm ua tau ntau lub hwj huam, nyob rau hauv rooj plaub ntawm lub siab tshaj plaws kev sib hloov, ceev Nws yog tsawg thiab sai txo nrog nce hwj chim, ua nws haum rau daim ntaub ntawv nrog tsawg ceev thiab tus lag luam. Yog li no, qhov kev kub siab, dav dav, siab torque tso zis ntawm qeeb ceev, ceev teb thiab tsis muaj overshoot yog nws txoj kev loj tshaj.
3.2 servo lub cev muaj peev xwm ua tau zoo tshaj lwm cov tshuab
AC servo motors ua tau zoo dua cov cav hlau nyob rau ntau qhov sib tw. Txawm hais tias cov cav siv cav feem ntau siv los ua qeeb hauv qee lub sij hawm tshwj xeeb los yog qee qhov tsis tshua muaj teeb meem, AC servo motors tseem yog cov feem ntau siv. Lub cav, yog dab tsi qhov txawv ntawm qhov theem cav?
Ib qho txawv ntawm kev tswj hwm. Kev tswj xyuas qhov tseeb ntawm AC servo lub cev yog guaranteed los ntawm lub teb chaws tuaj sab nraud ntawm lub tsheb sab qaum, thaum lub sijhawm ob theem pib ntawm kev ua haujlwm yog 3.6 degrees thiab 18 degrees, thiab tsib theem ntawm cov kaujruam ua haujlwm ntawm kev ua haujlwm muaj qis dua 0.72 degrees thiab 0.36 degrees.
Thib ob, qhov txawv ntawm cov yam ntxwv qis tsawg. Stepper motors yog nquag muaj qee zaus kev vibration ntawm qis qis. Vim tias cov haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm, qhov tshwm sim ntawm tsawg zaus kev co yog txiav txim siab, thiab qhov tshwm sim no muaj teeb meem thiab tsis zoo rau kev lag luam ntawm lub tshuab, tab sis cov kev khiav haujlwm ntawm AC servo motor yog qhov chaw ruaj khov heev, txawm Thaum qis qis, nws tseem tuav cov kev nplhaib tsis muaj kev vibration. Qhov no vim tias qhov AC servo system muaj kev ua haujlwm ntawm cov hluav taws xob, thiab muaj kev ntsuam xyuas ntau zaus hauv lub cev, thiab thaum nws pom tias lub tshuab muaj ib qho chaw ua resonance, nws raug kho raws li qhov tsim nyog.
Muaj ntau qhov sib txawv ntawm lub caij nyoog ntawm lub caij nyoog, qhov muaj peev xwm tshaj, thiab qhov kev ua haujlwm khiav ceev thiab qhov kev ua haujlwm siab ceev. Hauv kev tsim cov txheej txheem ntawm kev tswj, nws yog ib qho tseem ceeb rau kev xav txog kev tswj hwm, tus nqi, thiab ntau lwm yam, thiab xaiv cov kev tswj xyuas kom tsim nyog rau lub sijhawm.
