Matoorku waa qayb muhiim ah oo ka mid ah korontada ku shaqeysaDaabacaha 3D, saxnaanteeda waxay la xiriirtaa saameynta daabacaadda 3D ee wanaagsan ama xun, guud ahaan daabacaadda 3D marka la isticmaalayo matoorka stepper.
Haddaba ma jiraan daabacayaal 3D ah oo isticmaala matoorada servo? Waa wax cajiib ah oo sax ah, laakiin maxaad ugu isticmaali weyday daabacayaasha 3D ee caadiga ah?
Hal cillad: aad bay qaali u tahay! Marka la barbardhigo daabacayaasha 3D ee caadiga ah, uma qalanto. Haddii ay u fiican tahay daabacayaasha warshadaha, waxay u badan tahay inay isku mid tahay, saxnaanta way hagaajin kartaa waxoogaa.
Halkan waxaan ku qaadan doonaa labadan matoor, falanqayn isbarbardhig oo faahfaahsan si loo arko farqiga u dhexeeya.
Qeexitaanno kala duwan.
Matoorka Stepper-kawaa qalab dhaqdhaqaaq gooni ah, way ka duwan tahay AC-ga caadiga ah iyoMatoorada DC, matoorada caadiga ah ee korontada loo rogo, laakiin matoorka stepper-ka ma aha, matoorka stepper-ka waa inuu helaa amar si uu tallaabo u qaado.
Matoorka Servo waa matoorka xakameeya shaqada qaybaha farsamada ee nidaamka servo, kaas oo ka dhigi kara xawaaraha xakamaynta, saxnaanta booska mid aad u sax ah, isla markaana u rogi kara calaamadda danabka wareegga iyo xawaaraha si uu u wado shayga xakamaynta.
In kasta oo labadooduba ay isku mid yihiin habka xakamaynta (xarigga garaaca iyo calaamadda jihada), haddana waxaa jira farqi weyn oo u dhexeeya isticmaalka waxqabadka iyo munaasabadaha codsiga. Hadda waa isbarbardhigga isticmaalka labada waxqabad.
Saxnaanta xakamaynta way ka duwan tahay.
Laba-wajimatoorka stepper-ka isku-dhafanXagal tallaabo guud ahaan waa , 1.8 °, 0.9 °
Saxnaanta xakamaynta matoorka AC servo waxaa damaanad qaadaya encoder-ka wareega ee ku yaal gadaasha shafka matoorka. Matoorka Panasonic AC servo oo si buuxda u dijitaal ah, tusaale ahaan, matoor leh encoder 2500-line caadi ah, garaaca wadnaha oo u dhigma waa 360°/10000=0.036° sababtoo ah tignoolajiyada soo noqnoqoshada afar-jibbaaran ee loo isticmaalo gudaha darawalka.
Matoorka leh 17-bit encoder, darawalku wuxuu helaa garaacis 217=131072 wareeg kasta oo matoor ah, taasoo la macno ah in garaacistiisu u dhigantaa 360°/131072=9.89 ilbiriqsi, taasoo ah 1/655 garaac oo u dhigma matoorka stepper-ka oo leh xagal tallaabo oo ah 1.8°.
Sifooyin kala duwan oo soo noqnoqoshada hooseeya ah.
Matoorka Stepper-ka oo xawaare hoose ku socda ayaa u muuqan doona dhacdo gariir oo soo noqnoqota oo hooseeya. Soo noqnoqoshada gariirku waxay la xiriirtaa xaaladda culayska iyo waxqabadka darawalka, waxaana guud ahaan loo arkaa inay tahay kala bar inta jeer ee aan la saarin culayska matoorka.
Dhacdadan gariirka ee soo noqnoqda yar ee lagu go'aamiyo mabda'a shaqada ee matoorka stepper-ka ayaa aad u waxyeellaysa shaqada caadiga ah ee matoorka. Marka matoorada stepper-ku ay ku shaqeeyaan xawaare hoose, tiknoolajiyadda ceejinta guud ahaan waa in loo isticmaalaa in lagu xalliyo dhacdada gariirka soo noqnoqda yar, sida ku darista ceejinta matoorka, ama isticmaalka tiknoolajiyadda qayb-qaybinta ee darawalka.
Matoorka AC servo wuxuu si aad u siman u shaqeeyaa mana gariiro xitaa xawaare hoose. Nidaamka AC servo wuxuu leeyahay shaqo xakameyn resonance ah, taas oo dabooli karta la'aanta adkaanta mishiinada, nidaamkuna wuxuu leeyahay shaqo xallinta soo noqnoqoshada gudaha, taas oo ogaan karta barta resonance ee mishiinada oo fududeyn karta hagaajinta nidaamka.
Waxqabadka hawlgalka ee kala duwan.
Xakamaynta matoorka Stepper waa xakamaynta wareegga furan, aad u sarreeya soo noqnoqoshada bilowga ama aad u weyn culaysku wuxuu u nugul yahay dhacdooyinka tallaabooyinka lumay ama xannibaadda, aad u sarreeya xawaaraha marka la joojinayo wuxuu u nugul yahay inuu kor u kaco, sidaa darteed si loo hubiyo saxnaantiisa xakamaynta, waa in wax laga qabtaa dhibaatada xawaaraha kor iyo hoos.
Nidaamka wadista AC servo ee xakamaynta wareegga xiran, darawalku wuxuu si toos ah u muunad karaa calaamadda jawaab celinta ee koodh-qoraha matoorka, halabuurka gudaha ee wareegga booska iyo wareegga xawaaraha, guud ahaan ma muuqan doono luminta matoorka stepper ee dhacdada tallaabada ama overshoot, waxqabadka xakamaynta ayaa aad loogu kalsoonaan karaa.
Marka la soo koobo, nidaamka AC servo dhinacyo badan oo waxqabadka ah ayaa ka wanaagsan matoorka stepper-ka. Laakiin mararka qaarna si fudud uma baahna, badanaa waxay isticmaalaan matoorka stepper-ka si ay u sameeyaan matoorka fulinta. Daabacaha 3D waa munaasabad aan dhib badnayn, matoorka servo-kuna aad buu qaali u yahay, sidaa darteed doorashada guud ee matoorka stepper-ka.
