Injini yinxalenye yamandla ebaluleke kakhulu kwiIphrinta ye-3D, ukuchaneka kwayo kunxulumene nesiphumo sokuprinta se-3D esihle okanye esibi, ngokubanzi ukuprinta kwe-3D ekusebenziseni i-stepper motor.
Ngaba kukho iiprinta ze-3D ezisebenzisa ii-servo motors? Ziyamangalisa kwaye zichanekile, kodwa kutheni ungazisebenzisi kwiiprinta ze-3D eziqhelekileyo?
Ingxaki enye: ibiza kakhulu! Xa ithelekiswa neeprinta ze-3D eziqhelekileyo ayifanelekanga. Ukuba ingcono kwiiprinta zemizi-mveliso ifana kakhulu, inokuphucula ukuchaneka kancinci.
Apha siza kuthatha ezi moto zimbini, uhlalutyo oluneenkcukacha lokuthelekisa ukuze sibone ukuba yintoni umahluko.
Iinkcazo ezahlukeneyo.
Imoto yesteppersisixhobo sokuhamba esizimeleyo, sahlukile kwi-AC eqhelekileyo kunyeIimoto zeDC, iimoto eziqhelekileyo ukuya kumbane ukuze zijike, kodwa i-stepper motor ayijiki, i-stepper motor ifumana umyalelo wokwenza inyathelo.
I-Servo motor yinjini elawula ukusebenza kwezixhobo zoomatshini kwinkqubo ye-servo, enokwenza isantya solawulo, ukuchaneka kwendawo kube ngokuchanekileyo kakhulu, kwaye inokuguqula isignali ye-voltage ibe yi-torque kunye nesantya sokuqhuba into yokulawula.
Nangona ezi zimbini zifana kwimowudi yolawulo (umtya we-pulse kunye nesignali yesikhokelo), kukho umahluko omkhulu ekusebenziseni ukusebenza kunye neemeko zokusetyenziswa. Ngoku kuthelekiswa ukusetyenziswa kokusebenza kwezi zimbini.
Ukuchaneka kolawulo kwahlukile.
Amanqanaba amabiniimoto ye-hybrid stepperi-engile yenyathelo ngokubanzi yi-, 1.8 °, 0.9 °
Ukuchaneka kolawulo lwemoto ye-AC servo kuqinisekiswa yi-rotary encoder ngasemva kwe-motor shaft. Kwimoto ye-AC servo yedijithali epheleleyo yePanasonic, umzekelo, kwimoto ene-2500-line encoder eqhelekileyo, i-pulse equivalent yi-360°/10000=0.036° ngenxa yetekhnoloji ye-frequency kane esetyenziswa ngaphakathi kwi-drive.
Kwimoto ene-encoder ye-17-bit, i-drive ifumana ii-pulses ezingama-217=131072 ngokujikeleza kwemoto nganye, oko kuthetha ukuba i-pulse equivalent yayo yi-360°/131072=9.89 seconds, eyi-1/655 ye-pulse equivalent yemoto ye-stepper ene-engile ye-step ye-1.8°.
Iimpawu ezahlukeneyo ze-low-frequency.
I-Stepper motor ngesantya esiphantsi iya kubonakala ngathi yi-low-frequency vibration. I-vibration frequency inxulumene nemeko yomthwalo kunye nokusebenza kwe-drive, kwaye ngokubanzi ithathwa njengesiqingatha se-no-load load frequency ye-motor.
Le nto yokungcangcazela engaphantsi kwesantya emiselwe ngumgaqo wokusebenza kwemoto ye-stepper iyingozi kakhulu ekusebenzeni okuqhelekileyo komatshini. Xa iimoto ze-stepper zisebenza ngesantya esiphantsi, iteknoloji yokudambisa kufuneka isetyenziswe ngokubanzi ukoyisa le nto yokungcangcazela engaphantsi kwesantya, njengokongeza ii-dampers kwimoto, okanye ukusebenzisa iteknoloji yokwahlulahlula kwi-drive.
Imoto ye-AC servo isebenza kakuhle kakhulu kwaye ayidlidlizi nokuba isantya siphantsi. Inkqubo ye-AC servo inomsebenzi wokunciphisa i-resonance, onokugubungela ukungabikho kokuqina komatshini, kwaye inkqubo inomsebenzi wokusombulula amaza angaphakathi, onokubona indawo ye-resonance yomatshini kwaye wenze kube lula ukulungelelanisa inkqubo.
Ukusebenza okwahlukileyo.
Ulawulo lwe-Stepper motor lulawulo oluvulekileyo, xa uqalisa rhoqo okanye umthwalo mkhulu kakhulu, lunokubangela ukuba amanyathelo alahlekileyo okanye uthintelwe, xa umisa ukhawuleza kakhulu, kufuneka ujongane nengxaki yokunyuka nokwehla kwesantya.
Inkqubo ye-AC servo drive yolawulo oluvaliweyo, umqhubi unokuthatha isampuli yesignali yempendulo ye-encoder yemoto ngqo, ukwakheka kwangaphakathi kwe-loop yesikhundla kunye ne-speed loop, ngokubanzi akuyi kuvela ukulahleka kwe-stepper motor ye-stepper okanye i-overshoot, ukusebenza kolawulo kuthembekile ngakumbi.
Ngamafutshane, inkqubo ye-AC servo kwiinkalo ezininzi zokusebenza ingcono kune-stepper motor. Kodwa kwezinye iimeko ezingenzima kangako, ikwasebenzisa ne-stepper motor ukwenza i-execution motor. Iprinta ye-3D ayinzima kangako, kwaye i-servo motor ibiza kakhulu, ngoko ke ukhetho oluqhelekileyo lwe-stepper motor.
