Matoorku waa qayb awood aad u muhiim ah oo ku saabsandaabacaha 3D, saxnaantiisa waxay la xiriirtaa saamaynta daabacaadda 3D ee wanaagsan ama xun, guud ahaan daabacaadda 3D ee isticmaalka matoorka stepper.
Markaa ma jiraan daabacayaal 3D ah oo adeegsada matoorada servo? Runtii waa wax laga cabsado oo sax ah, laakiin maxaad ugu isticmaali weyday daabacadaha 3D ee caadiga ah?
Hal cilad: aad bay qaali u tahay! Marka la barbardhigo daabacayaasha 3D ee caadiga ah maaha mid u qalma. Haddii ay u fiican tahay daabacayaasha warshadaha waa ka badan ama ka yar isku mid, waxay hagaajin kartaa saxnaanta wax yar.
Halkan waxaan ku soo qaadan doonaa labadan matoor, falanqayn is barbar dhig ah oo faahfaahsan si aan u aragno farqiga u dhexeeya.
Qeexitaanno kala duwan.
Matoorka Stepperwaa qalab dhaqdhaqaaq discrete ah, waa ka duwan yahay AC caadiga ah iyoMatoorada DC, matoorada caadiga ah si ay koronto u leexdaan, laakiin matoorka stepper ma aha, stepper motor waa in la helo amar si ay u qabtaan tallaabo.
Matoorka Servo waa matoorka kantaroola shaqada qaybaha farsamada ee nidaamka servo, kaas oo ka dhigi kara xawaaraha kontoroolka, saxnaanta booska mid aad u sax ah, oo u rogi kara calaamada danab u rogi kara iyo xawaare si uu u wado shayga kantaroolka.
Inkasta oo labaduba ay isku mid yihiin habka xakamaynta (xarigga garaaca wadnaha iyo calaamadda jihada), waxaa jira kala duwanaansho weyn oo isticmaalka waxqabadka iyo munaasabadaha codsiga. Hadda isbarbardhigga isticmaalka labada waxqabad.
Saxnaanta xakamaynta way ka duwan tahay.
Laba wajimashiinka stepper hybridxagal talaabo waa guud ahaan, 1.8 °, 0.9 °
Saxnaanta kontoroolka matoorka AC servo waxaa dammaanad qaaday codeeyaha wareegta ee xagga dambe ee shafka mootada. Wixii Panasonic si buuxda dhijitaalka ah AC servo motor, tusaale ahaan, matoor leh heerka 2500-line encoder, garaaca wadnaha u dhiganta waa 360 °/10000=0.036° sababtuna tahay tignoolajiyada soo noqnoqda afar jibaaran ee lagu isticmaalo gudaha drive.
Matoorka leh 17-bit encoder, darawalku wuxuu helayaa 217=131072 garaaca halkii kacaanka, taas oo macnaheedu yahay in garaaca garaaciisu yahay 360°/131072=9.89 sekan, taas oo ah 1/655 garaaca garaaca u dhigma motor stepper leh xagal tallabo ah.1.8°.
Sifooyin hoose oo kala duwan.
Matoorka Stepper ee xawaaraha hooseeya wuxuu u muuqan doonaa ifafaale gariir hooseeya. Inta jeer ee gariirku waxay la xiriirtaa xaaladda culeyska iyo waxqabadka wadista, waxaana guud ahaan loo arkaa inay tahay kala bar inta jeer ee bilaa-load ee matoorka.
Dhacdadan gariir-yar ee soo noqnoqota ee lagu go'aamiyay mabda'a shaqada ee matoorka stepper-ka ayaa aad u dhaawaceysa shaqada caadiga ah ee mashiinka. Marka matoorada stepper ay ku shaqeeyaan xawaare hooseeya, tignoolajiyada qoynta waa in guud ahaan loo adeegsadaa si looga gudbo ifafaalaha gariirada soo noqnoqda ee hooseeya, sida ku darista dampers mishiinka, ama isticmaalka tignoolajiyada qaybsiga ee wadista.
Matoorka AC servo wuxuu u shaqeeyaa si habsami leh mana gariiro xitaa xawli hoose. Nidaamka servo AC wuxuu leeyahay shaqada xakamaynta resonance, kaas oo dabooli kara la'aanta qallafsanaanta mishiinka, nidaamkuna wuxuu leeyahay shaqada xallinta soo noqnoqda gudaha, kaas oo ogaan kara barta dhawaaqa ee mishiinka oo fududeynaya hagaajinta nidaamka.
Waxqabad hawleed oo kala duwan.
Xakamaynta mootada Stepper waa kontoroolka wareegga furan, aad u sarreeya inta jeer ee bilawga ama culeyska aad u weyn ayaa u nugul ifafaalaha tallaabooyinka lumay ama xannibaadda, xawaaraha aad u sarreeya marka uu joogsado waxay u nugul tahay in la dhaafo, si loo hubiyo saxnaanta xakamaynta, waa in ay wax ka qabato dhibaatada xawaaraha kor iyo hoos.
Nidaamka wadista AC servo ee xakamaynta-loop-ka-xiran, darawalku si toos ah ayuu u muunad karaa calaamadda jawaab-celinta cod-bixinta motor-ka, hal-abuurka gudaha ee wareegga booska iyo xawaaraha xawaaraha, guud ahaan kama muuqan doono luminta mootada stepper ee tallaabo ama ifafaale xad dhaaf ah, waxqabadka xakamaynta ayaa ah mid la isku halleyn karo.
Marka la soo koobo, nidaamka servo AC ee dhinacyo badan oo waxqabad ah ayaa ka fiican mashiinka stepper. Laakiin marmarka qaar ee baahidoodu yar tahay sidoo kale inta badan adeegso matoorka wax-ka-qabashada si aad u samayso matoorka fulinta. Daabacaha 3D waa munaasabad ka yar baahida, iyo matoorka servo waa mid aad qaali u ah, sidaas darteed doorashada guud ee matoorka stepper.
