Li-stepper motor li fokotseha joang?

Li-motors tsa stepperke lisebelisoa tsa electromechanical tse fetolang ka ho toba tšusumetso ea motlakase hore e be motsamao oa mochini. Ka ho laola tatellano, maqhubu le palo ea matla a motlakase a sebelisoang ho li-coil tsa motlakase, li-motors tsa stepper li ka laoloa bakeng sa ho tsamaisa, lebelo le angle ea ho potoloha. Ntle le thuso ea mokhoa oa ho laola maikutlo a koalehileng ka mokhoa oa ho lemoha boemo, boemo bo nepahetseng le taolo ea lebelo li ka finyelloa ka ho sebelisa mokhoa o bonolo, o theko e tlaase oa ho laola loop o nang le mochine oa stepper le mokhanni o tsamaeang le oona.

Enjene ea ho hatakela joalo ka ntho ea tsamaiso, ke e 'ngoe ea lihlahisoa tsa bohlokoa tsa mechatronics, e sebelisoang haholo lits'ebetsong tse fapaneng tsa taolo ea othomathike. Ka nts'etsopele ea mahlale a mahlale a elektroniki le theknoloji e nepahetseng ea tlhahiso, tlhoko ea li-motors tsa stepper e ntse e eketseha letsatsi le letsatsi, 'me li-motors tsa stepper le mochini oa phetisetso oa gear li kopantsoe le li-gearbox, hape le maemong a mangata a ts'ebeliso ho bona, kajeno le motho e mong le e mong ho utloisisa mofuta ona oa mochini oa phetisetso ea gearbox.

Mokhoa oa ho fokotsa lebelostepper motor?

Joalo ka enjene ea koloi e sebelisoang hangata ebile e sebelisoa haholo, enjene ea stepper hangata e sebelisoa hammoho le lisebelisoa tsa deceleration ho fihlela phello e nepahetseng ea phetisetso; le lisebelisoa tse sebelisoang hangata ho fokotsa lebelo le mekhoa ea li-stepper motor li joalo ka li-gearbox tsa deceleration, li-encoder, li-controller, matšoao a pulse joalo-joalo.

Ho fokotseha ha lets'oao la Pulse: lebelo la enjene ea stepper, e ipapisitse le liphetoho tsa lets'oao la pulse ho fetoha. Ka khopolo, fa mokhanni ho otla ha pelo, thestepper motore potoloha sekhutlo sa mohato (e arotsoe bakeng sa karolo e arohaneng ea mohato). Ha e le hantle, haeba lets'oao la pulse le fetoha ka potlako haholo, motlakase oa stepper, ka lebaka la phello ea damping ea matla a ka hare a reverse electromotive, matla a khoheli a pakeng tsa rotor le stator a ke ke a khona ho latela liphetoho tsa pontšo ea motlakase, e leng se tla lebisa ho thibela le ho lahleheloa ke mohato.

Phokotso ea lebokose la li-gearbox: stepper motor e nang le lebokose la lisebelisoa tsa phokotso e sebelisoang hammoho, lebelo le phahameng la torque e tlase, e hokahantsoeng le lebokose la gear ea phokotso, lebokose la gear ka hare ho phokotso ea mesh phetisetso e entsoeng ka sekhahla sa phokotso, sekhahla sa phokotso ea lebelo le phahameng, le ho ntlafatsa torque ea phetisetso, ho fihlela phetisetso e nepahetseng ea phetisetso; phello ea deceleration e ipapisitse le tekanyo ea phokotso ea lebokose la gear, palo e kholo ea phokotso, e nyane lebelo la tlhahiso, le ka tsela e fapaneng. Phello ea ho fokotseha e ipapisitse le karo-karolelano ea phokotso ea li-gearbox, palo e kholo ea phokotso, e nyane lebelo la tlhahiso le ka tsela e fapaneng.

Curve exponential control speed: exponential curve, lenaneong la software, palo ea pele ea nako e bolokiloeng mohopolong oa khomphutha, mosebetsi o supa khetho. Hangata, nako ea ho potlakisa le ho theola lebelo ho phethela mochini oa stepper o feta 300ms. Haeba u sebelisa nako e khutšoanyane haholo ea ho potlakisa le ho fokotsa nako, bakeng sa boholo bali-motors tsa stepper, ho tla ba thata ho finyella ho potoloha ka lebelo le phahameng la mochine oa stepper.
