Indlela yokuqhuba yomatshini wokusika i-laser iqhutywa kakhulu yimoto. Abanye abathengi bajongene nokukhetha xa besenza ngokwezifiso umatshini wokusika i-laser yefayibha. Ngaba kukukhetha i-servo motor okanye i-stepper motor? Abavelisi bomatshini wokusika i-laser banokuhlalutya umahluko phakathi kweendlela ezimbini ezahlukeneyo zokuqhuba, Okokuqala, kufuneka siqonde umahluko phakathi kwe-servo motor kunye ne-stepper motor ekhethwe ngumatshini wokusika i-laser:
Imoto yeServo kunye ne-stepper motor zingasetyenziselwa ukuqhuba umatshini wokusika i-laser, amashishini amaninzi athenga umatshini wokusika i-laser ukukhetha owokuqala, kutheni? Imoto ye-servo inomsindo ophantsi kunye nokuchaneka okuphezulu. Imoto ye-AC servo isetyenziswa njengesixhobo sokuqhuba, esinokwenza inkqubo yokulawula i-semi-closed loop ephezulu kunye nokusebenza okuphezulu njengemoto ye-DC servo. Ngenxa yesakhiwo se-AC servo motor engenamabhrashi, phantse akukho londolozo, umthamo omncinci, onceda ekuphuculeni isantya namandla. Okwangoku, imoto ye-DC servo itshintshiwe kuluhlu olukhulu lwenkqubo ye-AC servo yedijithali epheleleyo kusetyenziswa i-microprocessor ekhawulezayo kunye neprosesa ekhethekileyo yesignali yedijithali (DSP), ulawulo lwe-servo lwehardware yokuqala lube kulawulo lwe-servo lwesoftware, ezinye ii-algorithms eziphambili kwithiyori yokulawula yanamhlanje ziye zafezekiswa, kwaye emva koko ziphucula kakhulu ukusebenza kwenkqubo ye-servo, ngoko ke iyunithi ye-servo inokuphucula kakhulu ukusebenza kakuhle kwe-machining kunye nokuchaneka, kodwa ixabiso leyunithi ye-servo drive nalo liphezulu. Ngokuphuculwa kancinci kancinci kwetekhnoloji yokulawula i-servo, iyunithi ye-servo drive iba ngamandla aphambili eyunithi ye-drive, kwaye ixabiso leyunithi ye-servo drive liyehla kancinci.
Kukho iintlobo ezimbini zabaqhubi be-servo. Omnye usebenzisa ulawulo lwe-pulse. Olu hlobo lomqhubi luvala iluphu nemoto, kodwa aluyi kubuyela kwinkqubo ye-CNC. Omnye usebenzisa imo yolawulo lwe-voltage, nge-voltage yolawulo lwesantya semoto, isignali yempendulo yemoto nge-feedback yomqhubi ukuya kwinkqubo ye-CNC ukuze kulawulwe isikhundla.
Xa ukhetha iyunithi yokuqhuba, kubalulekile ukuqwalasela umlinganiselo wexabiso leyunithi yokuqhuba kwisixhobo somatshini se-NC sonke, Ixabiso eliphantsi lesixhobo somatshini se-CNC siphela likhetha iyunithi yokuqhuba ye-stepper, kwaye ixabiso eliphezulu lesixhobo somatshini likhetha iyunithi yokuqhuba ye-servo. Nangona kunjalo, xa ukhetha iyunithi yokuqhuba, ingxaki yokufanisa phakathi kweyunithi yokuqhuba kunye nenkqubo ye-CNC nayo kufuneka iqwalaselwe. Xa ukhetha inkqubo yokulawula i-closed-loop, iyunithi yokuqhuba ye-servo evaliweyo kufuneka ikhethwe. Inkqubo ye-AC servo ingcono kune-stepper motor kwiinkalo ezininzi zokusebenza.
