I-Stepping Motor kanye ne-Servo Motor Difference

Tulawula izindlela ezahlukene

I-stepping motor (i-engeli ye-pulse, i-open-loop control): isignali ye-pulse kagesi iguqulwa ibe ukugudluka kwe-angular noma ukukhishwa komugqa wokulawula okuvulekile, esimweni sokungalayishwa ngokweqile, isivinini semoto, indawo ukuma kuncike kuphela ekuvaleni kwesignali ye-pulse kanye nenani lama-pulses, ngaphandle kwethonya lokushintsha komthwalo.

Ama-Stepper motors ahlukaniswa kakhulu ngokwenani lezigaba, kanti ama-motor ezigaba ezimbili nezigaba ezinhlanu asetshenziswa kakhulu emakethe. I-motor enezigaba ezimbili ingahlukaniswa ngezingxenye ezilinganayo ezingama-400 ngenguquko ngayinye, futhi isigaba sesihlanu singahlukaniswa sibe izingxenye ezilinganayo eziyi-1000, ngakho-ke izici zemotor enezigaba ezinhlanu zingcono, ukusheshisa okufushane kanye nesikhathi sokunciphisa, futhi kuphansi. inertia enamandla. I-engeli yesinyathelo se-2 hybrid stepping motor ngokuvamile ingu-3.6°, 1.8°, kanti i-engeli yesinyathelo se-five phase hybrid stepping motor ngokuvamile ingu-0.72°, 0.36°.

I-Servo motor (i-engeli yama-pulses amaningi, i-close-loop control): i-servo motor iphinde ibe ngokulawula inani lama-pulse, i-servo motor rotation angle, izothumela inombolo ehambisanayo yama-pulses, kuyilapho umshayeli ezothola impendulo isignali emuva, kanye ne-servo motor ukwenza ukuqhathanisa kwama-pulses, ukuze uhlelo luzokwazi inani lama-pulse athunyelwe ku-servo motor, futhi ngesikhathi esifanayo ukuthi mangaki ama-pulse atholakele emuva, azokwazi ukulawula ukujikeleza injini ngokunembe kakhulu. Ukunemba kwe-servo motor kunqunywa ukunemba kwesishumeki (inombolo yemigqa), okusho ukuthi, i-servo motor ngokwayo inomsebenzi wokuthumela ama-pulse, futhi ithumela inani elihambelanayo lama-pulses kuwo wonke ama-engeli ukuzungezisa, ukuze idrayivu ye-servo kanye ne-servo motor encoder pulses yakhe i-echo, ngakho-ke iyisilawuli se-loop evaliwe, futhi i-steping motor iyisilawuli se-loop evulekile.

Lizici ze-ow-frequency zihlukile

I-stepping motor: ukudlidliza kwe-low-frequency vibration kulula ukwenzeka ngesivinini esiphansi. Uma isitebhisi sisebenza ngesivinini esiphansi, ngokuvamile kufanele sisebenzise ubuchwepheshe bokumanzisa ukuze sinqobe into yokudlidliza enefrikhwensi encane, njengokwengeza into encibilikisa amanzi emoteni, noma ukushayela usebenzisa ubuchwepheshe bokuhlukanisa.

I-Servo motor: ukusebenza kahle kakhulu, ngisho nangesivinini esiphansi ngeke kuvele into yokudlidliza.

Tyena izici mzuzu-frequency ezahlukene

I-stepping motor: i-torque ephumayo iyancipha ngokunyuka kwejubane, futhi yehla kakhulu ngesivinini esiphezulu, ngakho-ke isivinini sayo esiphezulu sokusebenza ngokuvamile singu-300-600r/min.

I-Servo motor: i-torque ephumayo engaguquki, okungukuthi, ngesivinini sayo esilinganiselwe (ngokuvamile 2000 noma 3000 r/min), okukhiphayo kukalwe i-torque, ngesivinini esilinganiselwe ngaphezu kokuphuma kwamandla okungaguquki.

Dumthamo wokulayisha ngokweqile

I-stepping motor: ngokuvamile ayinawo amandla okulayisha ngokweqile. I-stepping motor ngoba ayikho umthamo onjalo wokulayisha ngokweqile, ukuze unqobe ukukhethwa kwalesi sikhathi se-inertia, ngokuvamile kudingekile ukukhetha i-torque enkulu ye-motor, futhi umshini awudingi i-torque eningi ngesikhathi sokusebenza okujwayelekile, kuyoba khona. kube yimfucuza ye-torque phenomenon.

Ama-Servo motors: anomthamo oqinile wokugcwala ngokweqile. Inamandla okulayisha ngokweqile kanye ne-torque. I-torque yayo ephezulu iphindwe kathathu kune-torque elinganiselwe, engasetshenziswa ukunqoba umzuzu we-inertial yemithwalo engasebenzi ngesikhathi sokuqala se-inertia.

Dukusebenza okuhlukile

I-stepping motor: isilawuli semoto esinyathelayo sokulawula i-open-loop, imvamisa yokuqala iphezulu kakhulu noma inkulu kakhulu umthwalo uthambekele ekulahlekelweni yizinyathelo noma ukuvimba ukwenzeka kokuma kakhulu isivinini sithambekele esenzweni sokudubuleka ngokweqile, ngakho-ke ukuze uqinisekise. ukunemba kokulawula kwayo, kufanele kubhekwane nenkinga yokukhuphuka nokwehla kwesivinini.

I-Servo motor: Isistimu ye-AC servo drive yokulawula iluphu evaliwe, umshayeli angaba ngqo kusampula yesignali ye-motor encoder impendulo, ukwakheka kwangaphakathi kweluphu yendawo kanye ne-speed loop, ngokuvamile akuveli ekulahlekeni kwemoto kwezinyathelo noma ukwenzeka kwe-overshooting, ukusebenza kokulawula kunokwethenjelwa kakhulu.

Sukusebenza kwempendulo yepeed kuhlukile

I-stepping motor: shesha ukusuka ekumeni kuya esivinini sokusebenza (imvamisa ukuphenduka okungamakhulu ambalwa ngomzuzu) kudinga ama-200 ~ 400ms.

I-Servo motor: Ukusebenza kokusheshisa kwesistimu ye-AC servo kungcono, ukusuka ekumeni kuyasheshisa ukuya esivinini esilinganiselwe esingu-3000 r/min, ama-millisecond ambalwa kuphela, angasetshenziselwa izidingo zokumisa ngokushesha kanye nezidingo zokunemba kwesikhundla sokulawula okuphezulu. inkambu.
