Ungayikhetha kanjani i-servo motor kanye ne-stepper motor？

Imodi yokushayela yomshini wokusika nge-laser iqhutshwa kakhulu yimoto. Amanye amakhasimende abhekene nokukhetha lapho enza ngokwezifiso umshini wokusika nge-laser yefayibha. Ingabe ukukhetha i-servo motor noma i-stepper motor? Abakhiqizi bomshini wokusika nge-laser bangahlaziya umehluko phakathi kwezindlela ezimbili zokushayela ezahlukene, Okokuqala, kufanele siqonde umehluko phakathi kwe-servo motor kanye ne-stepper motor ekhethwe umshini wokusika nge-laser:

I-Servo motor kanye ne-stepper motor zingasetshenziswa ukushayela umshini wokusika i-laser, amabhizinisi amaningi akhetha umshini wokusika i-laser, kungani? I-servo motor inomsindo ophansi kanye nokunemba okuphezulu. I-AC servo motor isetshenziswa njengedivayisi yokushayela, engakha uhlelo lokulawula i-semi-closed olunembe kakhulu futhi olusebenza kahle njenge-DC servo motor. Ngenxa yesakhiwo esingenamabhulashi se-AC servo motor, cishe akukho ukulungiswa, ivolumu encane, ekhuthaza ukuthuthukiswa kwesivinini namandla. Njengamanje, i-DC servo motor ithathelwe indawo kuhlu olukhulu lwesistimu ye-AC servo yedijithali egcwele kusetshenziswa i-microprocessor yesivinini esiphezulu kanye ne-special digital signal processor (DSP), ukulawulwa kwe-servo yehadiwe yokuqala kube yisoftware yokulawula i-servo, amanye ama-algorithms athuthukile ku-theory yokulawula yesimanje aqashelwe, bese ethuthukisa kakhulu ukusebenza kohlelo lwe-servo, ngakho-ke iyunithi ye-servo ingathuthukisa kakhulu ukusebenza kahle komshini kanye nokunemba, kodwa intengo yeyunithi ye-servo drive nayo iphezulu. Ngokuthuthuka kancane kancane kobuchwepheshe bokulawula i-servo, iyunithi ye-servo drive iba kancane kancane amandla amakhulu eyunithi yokushayela, futhi intengo yeyunithi ye-servo drive iyancipha kancane kancane.

Kunezinhlobo ezimbili zabashayeli be-servo. Omunye usebenzisa i-pulse control. Lolu hlobo lomshayeli luvala i-loop ne-motor, kodwa aluphindiseli ohlelweni lwe-CNC. Omunye usebenzisa imodi yokulawula i-voltage, ngokusebenzisa i-voltage yokulawula isivinini se-motor, isignali yempendulo ye-motor ngokusebenzisa impendulo yomshayeli ohlelweni lwe-CNC ukuze kulawulwe isikhundla.

Uma ukhetha iyunithi yokushayela, kubalulekile futhi ukucabangela isilinganiso sentengo yeyunithi yokushayela kulo lonke ithuluzi lomshini we-NC, Intengo ephansi yethuluzi lomshini we-CNC ivame ukukhetha iyunithi yokushayela ye-stepper, kanti intengo ephezulu yethuluzi lomshini ikhetha iyunithi yokushayela ye-servo. Kodwa-ke, uma ukhetha iyunithi yokushayela, inkinga yokufanisa phakathi kweyunithi yokushayela nohlelo lwe-CNC nayo kufanele icatshangelwe. Uma ukhetha uhlelo lokulawula lwe-closed-loop, iyunithi yokushayela ye-servo ye-closed-loop kumele ikhethwe. Uhlelo lwe-AC servo lungcono kune-stepper motor ezicini eziningi zokusebenza.
