I-Closed-loopama-stepper motorsbashintshe isilinganiso sokusebenza nezindleko ezinhlelweni eziningi zokulawula ukunyakaza. Impumelelo yama-motor aqhubekayo e-VIC closed-loop ivule nethuba lokushintsha ama-motor e-servo abizayo ngama-motor ashibhile.ama-stepper motors.Enanini elikhulayo lezinhlelo zokusebenza ezisezingeni eliphezulu zokwenza izinto ngokuzenzakalela kwezimboni, intuthuko kwezobuchwepheshe ishintsha isilinganiso sokusebenza nezindleko phakathi kwama-stepper motors nama-servo motors.
Ama-Stepper motors uma kuqhathaniswa nama-servo motors
Ngokokuhlakanipha okuvamile, izinhlelo zokulawula i-servo zisebenza kangcono ezisetshenziswayo lapho kudingeka khona isivinini esingaphezu kuka-800 RPM kanye nempendulo enamandla ephezulu. Ama-stepper motors afaneleka kakhulu ezisetshenziswayo ezinesivinini esiphansi, ukusheshisa okuphansi kuya kokuphakathi kanye ne-torque ephezulu yokubamba.
Ngakho-ke siyini isisekelo salokhu kuhlakanipha okuvamile mayelana nama-stepper motors nama-servo motors? Ake sikuhlaziye ngokuningiliziwe ngezansi.
1. Ubulula kanye nezindleko
Ama-Stepper motors awashibhile nje kuphela kune-servo motors, kodwa futhi kulula ukuwasebenzisa nokunakekela. Ama-Stepper motors azinzile uma emile futhi agcina indawo yawo (ngisho noma enemithwalo enamandla). Kodwa-ke, uma kudingeka ukusebenza okuphezulu kwezinye izinhlelo zokusebenza, kumele kusetshenziswe ama-servo motors abizayo futhi ayinkimbinkimbi.
2. Isakhiwo
Ama-stepper motorszungeza ngendlela eqondile, usebenzisa amakhoyili kazibuthe ukudonsa kancane kancane uzibuthe usuka endaweni eyodwa uye kwenye. Ukuze uhambise injini izikhundla eziyi-100 kunoma iyiphi indlela, isekethe idinga imisebenzi yokunyathela eyi-100 okufanele yenziwe enjinini. Ama-stepper motors asebenzisa ama-pulse ukuze afinyelele ukunyakaza okuqhubekayo, okuvumela ukubeka okunembile ngaphandle kokusebenzisa noma yiziphi izinzwa zempendulo.
Indlela yokunyakaza kwemoto ye-servo ihlukile. Ixhuma inzwa yesikhundla - okungukuthi i-encoder - ku-magnetic rotor futhi ihlale ibona indawo eqondile yemoto. I-servo iqapha umehluko phakathi kwendawo yangempela yemoto nendawo eqondisiwe futhi ilungisa ugesi ngokufanele. Lolu hlelo oluvaliwe lugcina imoto isesimweni esifanele sokunyakaza.
3. Isivinini kanye ne-torque
Umehluko ekusebenzeni phakathi kwama-stepper motors nama-servo motors uvela ezixazululweni zawo ezahlukene zokuklama ama-motor.Ama-stepper motorszinenani elikhulu kakhulu lama-pole kune-servomotor, ngakho-ke ukuguquka okugcwele kwe-stepper motor kudinga ukushintshaniswa okuningi kwamanje okugoqayo, okuholela ekwehleni okusheshayo kwe-torque ngesivinini esandayo. Ngaphezu kwalokho, uma i-torque ephezulu ifinyelelwa, i-stepper motor ingase ilahlekelwe umsebenzi wayo wokuvumelanisa isivinini. Ngenxa yalezi zizathu, ama-servo motor ayisisombululo esithandwayo ezinhlelweni eziningi zesivinini esikhulu. Ngokuphambene nalokho, inani eliphakeme lama-pole e-stepper motor linenzuzo ngesivinini esiphansi, lapho i-stepper motor inenzuzo ye-torque kune-servo motor enobukhulu obufanayo.
Njengoba ijubane likhuphuka, i-torque yemoto ye-stepper iyancipha
4. Ukubeka Indawo
Kukhona umehluko obalulekile phakathi kwama-stepper motors nama-servo motors ezinhlelweni zokusebenza lapho indawo eqondile yomshini idinga ukwaziwa ngaso sonke isikhathi. Ezinhlelweni zokunyakaza ezivulekile ezilawulwa ama-stepper motors, uhlelo lokulawula lucabanga ukuthi imoto ihlala isesimweni esifanele sokunyakaza. Kodwa-ke, ngemva kokuba kuhlangatshezwane nenkinga, njengemoto emile ngenxa yengxenye ebambekile, isilawuli asikwazi ukwazi indawo yangempela yomshini, okungaholela ekulahlekelweni kwesikhundla. Uhlelo oluvaliwe lwe-servo motor uqobo lunenzuzo: uma luvinjiwe yinto, luzolubona ngokushesha. Umshini uzoyeka ukusebenza futhi ngeke uphume endaweni efanele.
5. Ukusetshenziswa kokushisa namandla
Ama-motor e-open-loop stepper asebenzisa ugesi oqinile futhi akhipha ukushisa okuningi. Ukulawula ugesi ovaliwe kunikeza ugesi odingekayo kuphela kumjikelezo wejubane ngakho-ke kugwema inkinga yokushisa kwenjini.
Isifinyezo sokuqhathanisa
Izinhlelo zokulawula i-Servo zifaneleka kakhulu ezinhlelweni zokusebenza zesivinini esikhulu ezibandakanya izinguquko zomthwalo oguquguqukayo, njengezingalo zerobhothi. Izinhlelo zokulawula i-Stepper, ngakolunye uhlangothi, zifaneleka kakhulu ezinhlelweni zokusebenza ezidinga ukusheshisa okuphansi kuya kokuphakathi kanye ne-torque ephezulu yokubamba, njengeziphrinta ze-3D, ama-conveyor, ama-sub ax njll. Ngenxa yokuthi ama-stepper motors ashibhile, anganciphisa izindleko zezinhlelo zokwenza izinto ngokuzenzakalela uma esetshenziswa. Izinhlelo zokulawula ukunyakaza ezidinga ukusizakala ngezici zama-servo motors kuzodingeka zifakazele ukuthi la ma-motor abiza kakhulu afanele isisindo sawo ngegolide.
Ama-stepper motors anokulawula okuvaliwe
I-stepper motor enokulawula okuhlanganisiwe kwe-elekthronikhi ilingana ne-DC motor engenamabhulashi enezigaba ezimbili futhi ingenza ukulawula i-position loop, ukulawula i-speed loop, ukulawula i-DQ, kanye nezinye izindlela zokwenza izinto. I-single-turn absolute encoder isetshenziselwa ukushintshashintsha kwe-closed-loop, ngaleyo ndlela iqinisekise i-torque efanele kunoma yisiphi isivinini.
Ukusetshenziswa kwamandla aphansi nokugcina kupholile
Ama-motor e-VIC stepper asebenzisa amandla kahle kakhulu. Ngokungafani nama-motor e-open-loop stepper, ahlala esebenza ngomyalo wamanje ogcwele futhi abangele izinkinga zokushisa nomsindo, ugesi uyashintsha ngokuya ngezimo zangempela zokunyakaza, isibonelo ngesikhathi sokusheshisa nokunciphisa ijubane. Njengoba kunjalo ngama-servo, ugesi osetshenziswa yilawa ma-motor e-stepper nganoma yisiphi isikhathi ulingana ne-torque yangempela edingekayo. Ngenxa yokuthi i-motor kanye nebhodi lokulawula elekthronikhi elihlanganisiwe lisebenza ngokupholile, ama-motor e-VIC stepper angafinyelela ama-torque aphezulu kakhulu afana nama-motor e-servo.
Ngisho noma ngesivinini esikhulu, ama-motor e-VIC stepper adinga amandla amancane kagesi
Eqhutshwa yintuthuko kwezobuchwepheshe obuvaliwe, ama-stepper motors ayakwazi ukungena ekusebenzeni okuphezulu, okushesha kakhulu okwakungekwama-servo motors kuphela.
Ama-stepper motors anobuchwepheshe be-closed-loop
Kuthiwani uma izinzuzo zobuchwepheshe be-servo obuvaliwe zingasetshenziswa kuma-stepper motors?
Singafinyelela yini ukusebenza okufana nama-servo motors ngenkathi sisaqaphela izinzuzo zezindleko zama-stepper motors?
Ngokuhlanganisa ubuchwepheshe bokulawula i-closed-loop, i-stepper motor izoba umkhiqizo ophelele onezinzuzo zombili ze-servo kanye ne-stepper motors ngentengo ephansi. Ngenxa yokuthi ama-closed-loop stepper motors anikeza ukuthuthukiswa okukhulu ekusebenzeni nasekusebenziseni kahle kwamandla, angathatha indawo yama-servo motors abizayo ngenani elikhulayo lezinhlelo zokusebenza ezisezingeni eliphezulu.
Okulandelayo yisibonelo semoto ye-stepper ehlanganisiwe ye-VIC enokulawulwa kwe-closed-loop okuhlanganisiwe ukuchaza ukusebenza kanye nezinzuzo kanye nokungalungi kwamamoto e-stepper anobuchwepheshe be-closed-loop.
Izidingo zokusebenza ezihambisana kahle
Ukuze kuqinisekiswe i-torque eyanele yokunqoba ukuphazamiseka nokugwema izinyathelo ezilahlekile, ama-motor e-open-loop stepper ngokuvamile kudingeka aqinisekise ukuthi i-torque iphakeme okungenani ngo-40% kunenani elidingekayo yisicelo. Ama-motor e-Closed-loop today stepper awanalo le nkinga. Uma la ma-motor e-stepper ema ngenxa yokugcwala ngokweqile, azoqhubeka nokubamba umthwalo ngaphandle kokulahlekelwa i-torque. Azoqhubeka nokusebenza ngemva kokuba isimo sokugcwala ngokweqile sesisusiwe. I-torque ephezulu ingaqinisekiswa nganoma yisiphi isivinini esinikeziwe futhi inzwa yesikhundla iqinisekisa ukuthi akukho ukulahleka kwesinyathelo. Ngakho-ke ama-motor e-Closed-loop stepper angachazwa ukuze afane ncamashi nezidingo ze-torque zesicelo esifanele ngaphandle kwesidingo se-margin eyengeziwe engu-40%.
Ngama-motor e-open-loop stepper, kunzima ukuhlangabezana nezidingo ze-torque ephezulu ngokushesha ngenxa yengozi yezinyathelo ezilahlekile. Uma kuqhathaniswa nama-motor e-stepper avamile, ama-motor e-VIC closed-loop stepper angafinyelela ukusheshisa okusheshayo kakhulu, umsindo ophansi wokusebenza kanye ne-resonance ephansi. Angasebenza kuma-bandwidth aphezulu kakhulu futhi afinyelele ukusebenza okuhle kakhulu.
Akukho ikhabhinethi
I-Toda ihlanganisa ibhodi lokulawula idrayivu nenjini, inciphisa inani lezintambo futhi yenza kube lula ukusebenzisa ikhambi. Nge-toda, ungakha imishini ngaphandle kwamakhabethe.
Ukuhlanganisa izinto zikagesi nezinjini ze-stepper kunciphisa ubunzima
Ngobuchwepheshe be-closed-loop, ama-closed-loop stepper motors anikeza abasebenzisi ukunemba nokusebenza kahle okuhle kakhulu, ngokusebenza kwe-servo motor kanye nezindleko eziphansi ze-stepper motor. Ama-stepper motors abiza kancane kancane angena kancane kancane ezinhlelweni zokusebenza ebezizobuswa ama-servo motors abiza kakhulu.
