Ho na le phapang e kholo lipakeng tsa li-linear stepper motor actuators le linear servo motor actuators ho latela mekhoa ea taolo, litšobotsi tsa ts'ebetso, le maemo a sebetsang. Liphapang tse khethehileng ke tse latelang:

1. Melao-motheo e fapaneng ea taolo

Linear stepper motor actuator: e sebelisa -loop control e bulehileng, e khanna koloi ho potoloha (kapa ho tsamaea ka tsela e otlolohileng) sebakeng se tsitsitseng ka ho amohela mats'oao a ho otla ha pelo, 'me phallo e tsamaisana hantle le palo ea maqhubu, ntle le tlhoko ea lisensara tsa boemo. Ha feela lets'oao la pulse le nepahetse, motsamao o hlophisitsoeng esale pele o ka finyelloa, empa e ke ke ea utloa hore na boemo ba 'nete bo kheloha taelo.

Linear servo motor actuator: e sebelisa taolo e koetsoeng-ea lupu, e kopanya lisensara tsa boemo (joalo ka rula ea grating, encoder), 'me e khutlisetsa boemo le lebelo ho molaoli ka nako ea nnete. Molaoli o bapisa boleng ba taelo le boleng ba maikutlo, o fetola ka mokhoa o matla tlhahiso ho netefatsa ho nepahala ha motsamao, 'me a ka lokisa ho kheloha ho bakoang ke liphetoho tsa mojaro le liphoso tsa mochini.

2. Ho nepahala ho fapaneng le bokhoni ba ho sebetsana le liphoso

Linear stepper motor actuator: ho nepahala ho ipapisitse le ho ts'oana ha sekhahla sa mohato (kapa mohato oa mola), ntle le bokhoni ba ho lokisa phoso. Haeba mojaro o le moholo haholo 'me maqhubu a pulse a phahame haholo, ho ka' na ha e-ba le tahlehelo ea mehato (ho falla ha sebele ho ka tlaase ho moo ho laetsoeng), 'me liphoso li tla bokellana. Ho nepahala ha mohato hangata ke ± 0.01mm 0.1mm.

Linear servo motor actuator: Ho lokisa liphoso tsa nako ea 'nete ka ho koala-poelo ea loop, bokhoni bo matla ba ho thibela{1}}tšitiso, ho nepahala ho phahameng ho pheta-pheta (ho fihla ho ± 0.001mm 0.01mm), le haeba ho na le ho feto-fetoha ha thepa kapa tšitiso ea kantle, e ka khutlisetsoa boemong bo laetsoeng ka tokiso ntle le phoso e akaretsang.

3. Lebelo le fapaneng le karabelo e matla

Linear stepper motor actuator: ts'ebetso e tsitsitseng e tlase-ka lebelo le tlase, empa e tloaetse ho sisinyeha le ho lahleheloa ke mohato nakong ea ts'ebetso-e phahameng, 'me torque ea tlhahiso e fokotseha ka lebelo le ntseng le eketseha (ho na le kotsi ea "tahlehelo ea mohato"), e loketseng maemo a tlase-a lebelo le a nakoana.

Linear servo motor actuator: Ka karabelo e potlakileng-ea lebelo le ho koalehile{1}}loop control, e ka boloka tlhahiso e tsitsitseng ho latela lebelo le pharaletseng. Ho potlakisa le ho theola lebelo ho bonolo, ho etsa hore e lokele maemo a hlokang ho emisa ho qala ka potlako kapa motsamao o tsoelang pele o phahameng-ka lebelo le phahameng.

4. Matla a fapaneng a mojaro le litšobotsi tsa torque

Linear stepper motor actuator: Torque ea tlhahiso (kapa thrust) e fokotseha ka lebelo le ntseng le eketseha. Ka lebelo le tlaase, torque e kholoanyane, empa ka lebelo le phahameng, e atisa ho imeloa tlas'a meroalo e boima. E loketse meroalo e bobebe (hangata e ka tlase ho 500N) le maemo a tlase a inertia.

Linear servo motor actuator: Ka -loop control e koetsoeng, matla a hlahisoang a ka feto-fetoha ho latela liphetoho tsa mojaro. E na le matla a matla a ho sebetsa-ka lebelo le phahameng-e boima, 'me e khona ho boloka lebelo le tsitsitseng ka lebelo le holimo. E loketse maemo a nang le meroalo e mahareng ho isa holimo (ho fihlela ho li-newtons tse likete) le inertia e phahameng.

5. Litšenyehelo tse fapaneng le mathata

Linear stepper motor actuator: sebopeho se bonolo, ha ho hlokahale lisensara tsa maikutlo, potoloho e nolofalitsoeng ea taolo, litšenyehelo tse tlase (hangata 1/3~1/2 ea servo system), bothata bo tlase ba ho lokisa bothata, bo loketseng lisebelisoa tse nyane le tse mahareng{4}} tse nang le tekanyetso e lekanyelitsoeng.

Linear servo motor actuator: e hloka ho kopanngoa ha lisensara le mekhoa e rarahaneng e koetsoeng-loop control algorithms, e leng theko e boima, 'me ho lokisa bothata (joalo ka parameter tuning) ho thata haholoanyane, ho etsa hore e lokele lisebelisoa tse nepahetseng tse nang le litlhoko tse phahameng tsa ts'ebetso.

6. Maemo a fapaneng a sebetsang

Linear stepper motor actuator: e loketse ho nepahala ha tlase, mojaro o bobebe, maemo a tlase-a ipheta-phetang, joalo ka phepelo ea nozzle ea printa ea 3D, lisebelisoa tse nyane tsa ho tsamaisa, boemo ba sampole ea laboratori, taolo ea li-valve tsa lapeng, jj.

Linear servo motor actuator: e loketse maemo a holimo-e phahameng, mojaro o phahameng,{1}}maemo a karabelo a matla a holimo{1}, joalo ka semiconductor wafer handling, laser cutting positioning, liroboto tse kopaneng hantle, lisebelisoa tsa ho buoa tsa bongaka, jj.
