Uyawazi umehluko phakathi kwe-stepper motor ne-servo motor?

Injini ye-Servo
1, Isimiso sokusebenza
Lezi zinjini ezimbili zihluke kakhulu ngokomthetho, i-stepper motor iyisignali kagesi yokushaya kwenhliziyo ibe yi-angular displacement noma i-linear displacement yezingxenye ze-stepper motor ze-open-loop control element, bheka isimiso sokusebenza se-stepper motor.

Futhi i-servo incike kakhulu ekushayweni kwe-pulse endaweni, i-servo motor ngokwayo inomsebenzi wokuthumela ama-pulse, ngakho-ke i-servo motor njalo lapho ijikeleza i-engeli, izothumela inani elihambisanayo lama-pulse, ukuze, kanye ne-servo motor ukwamukela i-pulse yakhe i-echo, noma i-closed loop, ukuze uhlelo lucace ukuthi zingaki ama-pulse athunyelwe futhi amukelwe ukuthi zingaki ama-pulse abuyele emuva, ukuze ikwazi ukulawula ngokunembile ukujikeleza kwe-motor ukuze ifinyelele indawo efanele.

2, ukunemba kokulawula
Ukunemba kwenjini ye-stepper ngokuvamile kufinyelelwa ngokulawula okunembile kwe-engeli yesinyathelo, enamagiya amaningi ahlukene okuhlukanisa ukuze kufezwe ukulawula okunembile.

Ukunemba kokulawula kwemoto ye-servo kuqinisekiswa yi-rotary encoder ekugcineni kwe-shaft yemoto, futhi ukunemba kokulawula kwemoto ye-servo ngokuvamile kuphakeme kunokwemoto ye-stepper.

3, Isivinini kanye nomthamo wokulayisha ngokweqile
Imoto ye-Stepper esebenza ngesivinini esiphansi ithambekele ekudlidlizeni okunemvamisa ephansi, ngakho-ke lapho imoto ye-stepper isebenza ngesivinini esiphansi, ngokuvamile idinga ukusebenzisa ubuchwepheshe bokufiphaza ukuze inqobe lesi simo sokudlidliza okunemvamisa ephansi, njengokufaka ama-dampers kumoto noma idrayivu kusetshenziswa ubuchwepheshe bokuhlukanisa, njll., kuyilapho imoto ye-servo ingeyona into eyenzeka kulesi simo, izici zayo zokulawula ezivaliwe zinquma ukusebenza kwayo ngesivinini esiphezulu ukuze kugcinwe ukusebenza okuhle kakhulu. Izici zemvamisa yesikhashana zalezi zimbili zihlukile, futhi ngokuvamile isivinini esilinganiselwe semoto ye-servo sikhulu kunesemoto ye-stepper.

I-torque yokukhipha yemoto ye-stepper iyancipha njengoba ijubane likhuphuka, kuyilapho i-servo motor ingumphumela we-torque oqhubekayo, ngakho-ke i-stepper motor ngokuvamile ayinawo amandla okulayisha ngokweqile, kuyilapho i-AC servo motor inekhono elinamandla lokulayisha ngokweqile.

4, Ukusebenza kahle
Ama-Stepper motors ngokuvamile alawula i-open-loop, uma imvamisa yokuqala iphezulu kakhulu noma umthwalo umkhulu kakhulu, ngeke ube sesimweni esifanelekile noma esingenaso isinyathelo, ngakho-ke ukusetshenziswa kwesidingo sokubhekana nezinkinga zesivinini noma ukwandisa i-encoder control closed-loop, bheka ukuthi iyini i-closed-loop stepper motor. Ngenkathi ama-servo motors esebenzisa i-closed-loop control, kulula ukuyilawula, akukho ukulahleka kwe-step phenomenon.

 5. Izindleko

I-Stepper motor inenzuzo maqondana nokusebenza kwezindleko, ukuze kufezwe umsebenzi ofanayo esimweni se-servo motor, intengo inkulu kune-stepper motor enamandla afanayo, impendulo ephezulu ye-servo motor, isivinini esikhulu kanye nezinzuzo zokunemba okuphezulu kunquma intengo ephezulu yomkhiqizo, okuyinto engenakugwenywa.

Ngamafuphi, ama-stepper motors nama-servo motors kokubili kusukela kusimiso sokusebenza, ukunemba kokulawula, umthamo wokulayisha ngokweqile, ukusebenza kahle kanye nezindleko kukhona umehluko omkhulu. Kodwa lokhu kokubili kunezinzuzo zako, abasebenzisi abafuna ukukhetha kuzo kudingeka bahlanganise izidingo zabo zangempela kanye nezimo zohlelo lokusebenza.
