I-Stepping Motor kanye ne-Servo Motor Difference

Tulawula izindlela ezahlukene

I-Stepping motor (i-angle ye-pulse, i-open-loop control): isignali ye-pulse kagesi iguqulwa ibe i-angular displacement noma ukukhishwa komugqa wesilawuli se-open-loop, esimweni sokungalayishwa ngokweqile, isivinini semoto, isikhundla sokumisa sincike kuphela ekuvameni kwesiginali 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 ezingu-400 ngenguquko ngayinye, futhi isigaba sesihlanu singahlukaniswa sibe izingxenye ezilinganayo ezingu-1000, ngakho izici ze-motor enezigaba ezinhlanu zingcono, ukusheshisa okufushane kanye nesikhathi sokunciphisa, kanye ne-inertia ephansi 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-angle yama-pulses amaningi, i-close-loop control): i-servo motor iphinde ibe ngokulawula inani lama-pulses, i-servo motor rotation angle, izothumela inombolo ehambisanayo yama-pulses, kuyilapho umshayeli ezothola isignali yempendulo emuva, kanye ne-servo motor ukwenza ukuqhathanisa kwama-pulses, ukuze uhlelo luzokwazi inani lama-pulse atholwe ngesikhathi esifanayo nama-pulses athunyelwe ngesikhathi esifanayo. emuva, uzokwazi ukulawula ukujikeleza kwemoto ngokunembe kakhulu. Ukunemba kwe-servo motor kunqunywa ukunemba kwe-encoder (inombolo yemigqa), okusho ukuthi, i-servo motor ngokwayo inomsebenzi wokuthumela ama-pulse, futhi ithumela inombolo ehambisanayo yama-pulses kuwo wonke ama-engeli wokujikeleza, ukuze i-servo drive kanye ne-servo motor encoder pulses yakhe i-echo, i-loop evulekile yokulawula i-motor-loop iyisilawuli esivaliwe.

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 ngenxa yokuthi awukho 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 nokuchithwa kwento ye-torque.

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 into yokuma kakhulu isivinini sithambekele entweni yokudubuleka ngokweqile, ngakho-ke ukuze kuqinisekiswe ukunemba kokulawula kwayo, kufanele kubhekwane nenkinga yokukhuphuka nokuwa kwejubane.

I-Servo motor: Isistimu ye-AC servo drive yokulawula iluphu evaliwe, umshayeli angaba ngokuqondile kusampula yesignali ye-encoder yempendulo, ukwakheka kwangaphakathi kweluphu yendawo kanye ne-loop yesivinini, ngokuvamile akuveli ekulahlekeni kwezimoto ezinyathelayo noma isenzakalo sokudutshulwa ngokweqile, 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, kusukela ekumeni kuyasheshisa kuya esivinini sayo esilinganiselwe esingu-3000 r/min, ama-millisecond ambalwa kuphela, angasetshenziselwa izidingo zokumisa ngokushesha kanye nezidingo zokunemba kwesikhundla sokulawula insimu ephezulu.
