Uyini umehluko phakathi kwe-servo motor ne-step motor ekusetshenzisweni kwamathuluzi womshini wokunemba?

I-servo motor ifana ne-stepper motor ekusebenzeni nasekwakhiweni, kepha ukusebenza kwe-servo motor kuhluke kakhulu. Yini umehluko ocacile? Uyini umehluko phakathi kwe-servo motor ne-step motor ekusetshenzisweni kwamathuluzi womshini wokunemba?

Okokuqala, izici zemvamisa ephansi ye-servo motor kanye ne-stepper motor yehlukile.

I-Stepper motor ithambekele ekudlidlizeni kwemvamisa ephansi ngejubane eliphansi. Isimiso esisebenzayo sesinyathelo semoto sinquma ukuthi into ephansi yokundlidliza kwefrimu ayithandi ukusebenza okujwayelekile komshini. Amashayeli amaningi wesinyathelo abale ngokuzenzakalela amaphuzu awo okudlidliza ukulungisa i-algorithm yokulawula ukucindezela ukudlidlizela kwawo.

I-Ac servo motor isebenza ngokushelela kakhulu, noma ngejubane eliphansi ngeke kuvele into yokudlidliza. Uhlelo lwe-Ac servo lunomsebenzi wokucindezelwa kwe-resonance, okungenza ukungabi bikho kobunzima bemishini, futhi lunomsebenzi wokuhlaziya imvamisa (FFT) ngaphakathi kohlelo, olungathola iphuzu lokuphindaphindeka kwemishini futhi lwenze lula ukulungiswa kohlelo.
Okwesibili, ukusebenza kwe-servo motor kanye ne-stepper motor kwehlukile.

Ukulawulwa kwemoto yokunyathela kuvulekile kwe-loop control, imvamisa yokuqala iphezulu kakhulu noma umthwalo mkhulu kakhulu, futhi isimangaliso se-overshoot noma i-overshoot kulula ukuvela lapho isivinini siphezulu kakhulu, ukuze kuqinisekiswe ukulawula ukunemba kwayo, izinkinga zokukhuphuka nokuwa kwejubane kufanele kubhekwane nazo kahle. Uhlelo lwe-AC servo drive luvaliwe ukulawula iluphu. Umshayeli angasampula ngqo isignali yempendulo ye-motor encoder. Indandatho yokuma nendandatho yejubane zakheka ngaphakathi. Ngokuvamile, akukho ukulahleka kwesinyathelo noma ukudlula imoto yokunyathela, futhi ukusebenza kokulawula kunokwethenjelwa.

Okwesithathu, izici zesikhashana semvamisa ye-servo motor ne-stepper motor zihlukile.

I-torque yokukhipha ye-stepper motor iyancipha ngokwanda kwejubane, futhi izokwehla kakhulu ngejubane eliphakeme, ngakho-ke isivinini esikhulu sokusebenza se-stepper motor ngokuvamile siyi-300 ~ 600 RPM .. I-torque yokukhipha ye-stepper motor izokwehla ngokucijile ngejubane eliphakeme I-AC servo motor ukuphuma okukhipha i-torque, okungukuthi, ngaphakathi kwejubane layo elilinganisiwe (imvamisa i-2000 RPM noma i-3000 RPM), ingakhipha i-torque elinganisiwe namandla akhishwa njalo ngaphezu kwesivinini esikaliwe.

Okwesine, ukusebenza kwempendulo yejubane lemoto ye-servo kwehlukile.

I-stepper motor ithatha ama-millisecond angama-200 ~ 400 ukusheshisa ukusuka ekuphumuleni kuye esivinini sokusebenza, imvamisa kungamakhulu wezinguquko ngomzuzu. Ukusebenza kokusheshisa kohlelo lwe-AC servo kuhle. Ukuthatha iMingzhi 400 W AC servo motor njengesibonelo, kuthatha ama-millisecond ambalwa ukusheshisa ukusuka ku-static kuye kusivinini sayo esilinganisiwe se-3000 RPM esingasetshenziswa esimweni sokulawula esidinga ukuqala nokuma okusheshayo.

Kwezinye izimo ezidinga kakhulu, kufanele kusetshenziswe izinjini ze-servo ezinokusebenza okuphezulu kakhulu kunama-stepper motors. Yize iChina inesigaba sezimboni esiphelele kunazo zonke emhlabeni, iningi laso lisemkhakheni we "onesibindi futhi okhululekile", futhi kusekhona igebe elikhulu ekuqongeleleni imikhiqizo esezingeni eliphezulu.

Okwesihlanu, ukunemba kokulawulwa kwezimoto ze-servo ne-stepper kuhlukile.

I-engeli yesinyathelo semoto enezinyathelo ezimbili ye-hybrid stepping motor ingu-1.8,0.9, kuthi eyesigaba esisihlanu se-hybrid stepping motor ingu-0.72,0.36. Kodwa-ke, ukunemba kokulawula kwe-AC servo motor kuqinisekiswe yisifaki khodi sokujikeleza ekugcineni kwangemuva kweshafu shaft. Okwe-motor ene-encoder eyi-17 bit, i-
