Ukukhetha phakathi kwe-servo motor kunye ne-stepper motor kungaba ngumngeni omkhulu kubandakanya ukulingana kwezinto ezininzi zokuyila. Iindleko zokuqwalasela, i-torque, isivinini, ukukhawuleza, kunye nokuqhutyelwa kweesekethe zombini zidlala indima ekukhetheni imoto engcono kakhulu kwisicelo sakho.
Ulwahlulo oluyisiseko phakathi kwe-Stepper kunye ne-Servo Motors
I-Stepper ne-servo motors zihluke ngeendlela ezimbini ezibalulekileyo, kwindlela yokwakha eyisiseko nendlela abalawulwa ngayo. Iimoto ze-stepper zinombumba omkhulu wemigodi, iimbini zamagnesi ezisentla kunye namantla ezantsi aveliswe ngumbane ogxininisekile okanye umbane wamanzi, ngokuqhelekileyo iipolisi ezingama-50 ukuya ku-100. Xa kuthelekiswa, i-servo motors ineepalo ezimbalwa kakhulu, ngokuphindaphindiweyo ezi-4 ukuya kwe-12 zizonke. I-pole nganye inika indawo yokumisa yemvelo ye-shaft. Ininzi enkulu yezibonda zivumela i-motor stepper ukuba ihambe ngokuchanekileyo kwaye ichanekileyo phakathi kwepolisi nganye kwaye ivumela ukuba umqhubi asebenze ngaphandle kwempendulo yezikhundla kwezicelo ezininzi. Iimoto ze-Servo zisoloko zifuna i-encoder ye-position ukugcina umgca wesimo se-motor shaft, ingakumbi ukuba kufuneka ukunyakaza okuchanekileyo.
Ukuqhuba i-motor stepper kwindawo echanekileyo kulula kakhulu kunokuqhuba imoto ye-servo. Ngomqhubi we-stepper, i-pulse eyodwa ye-drive iya kushukumisela isitrha somthi esinye isinyathelo, ukusuka kwesinye isiqalo ukuya kwesinye. Ekubeni ubukhulu bezithuthi zinikezelwe ngokumalunga nomlinganiselo othile wokujikeleza, ukunyuka kwindawo echanekileyo yinto nje yokuthumela inani elifanelekileyo leentlobo. Ngokungafaniyo ne-servo motors funda umehluko phakathi kweendawo zangoku zekhowudi kunye nesimo abayalelwe kuso kwaye nje kuphela okufunekayo ukuhamba kwindawo echanekileyo. Ngombane wedijithali wanamhlanje, iimoto ezihamba phambili zilula ukulawula ngaphezu kwee-motors.
Inzuzo ye Stepper
Iimoto zamagosa zinikela ngeenzuzo ezininzi kwi-servo motors ngaphaya kwenani elikhulu leembalo kunye nokulawula ukuqhuba lula. Uyilo lomqhubi we-stepper lunikeza isibonakaliso sokubamba ngaphandle kwesidingo sokuba imoto inikwe amandla. Iqhosha lomqhubi we-stepper kwixabiso eliphantsi likhulu kune-servo motor ofanayo. Enye yeenzuzo ezikhulu kakhulu zeenjini ze-stepper zindleko zabo eziphantsi kunye nokufumaneka.
Servo Benevantages
Kwiifowuni apho isantya esiphezulu kunye ne-torque ephezulu ifunekayo, i-servo motors iyakhanya. Iimoto ze-stepper zihamba ngeenxa zonke kwi-RPM engama-2,000, ngelixa i-servo motors zifumaneka ngokukhawuleza ngokukhawuleza. Ama-motors ase-Servo nawo agcina i-torque ukulinganisela kwisantya esiphezulu, ukuya kwi-90% ye-torque elinganisiwe ifumaneka kwi-servo ngesivinini esiphezulu. Ii-motors ze-Servo nazo ziphumelele ngakumbi kunama-stepper motors ngokusebenza kakuhle phakathi kwama-80-90%. Umqhubi we-servo unokubonelela ngokuphindaphindiweyo kabini i-torque elinganisweyo ngamaxesha ambalwa, ukubonelela umthombo wamandla okuba udwebe ukususela xa kufuneka. Ukongezelela, i-servo motors impela, ifumaneka kwi-AC ne-DC drive, kwaye ningadindi okanye nibe neengxaki ze-resonance.
Stepping Limitations
Kuzo zonke iinzuzo zabo, iimoto ezihambayo zinemiqathango embalwa enokubangela ukuphunyezwa okukhulu kunye nokusebenza ngokuxhomekeke kwisicelo sakho. Amashishini ase Stepper ayinawo amandla okugcina. Enyanisweni, iimoto ezihambayo zilahlekelwa ngumlinganiselo obalulekileyo wefowuni yazo njengoko zisondela kwisantya esiphezulu somqhubi. Ukulahleka kwama-80% we-couple torated kwi-90% yesantya esiphezulu. Iimoto ze-Stepper nazo azikho ezinjengezixhobo ze-servo ekukhawulezeni umthwalo. Ukuzama ukukhawuleza umthwalo ngokukhawuleza apho u-stepper akakwazi ukuvelisa i-torque eyaneleyo ukuya kwisinyathelo esilandelayo ngaphambi kokuba i-pulse ye-drive elandelayo ibangele isinyathelo esiphambukayo kunye nokulahleka kwindawo. Ukuba ukuchaneka kwemeko kubalulekile, nokuba umthwalo kwi-motor kufuneka ungadluli i-torque yayo okanye i-stepper kufuneka idibaniswe ne-encoder ye-position ukuqinisekisa ukuchaneka kwangoku. Iimoto ze-Stepper nazo zixhamla kwiingxaki zokudumala kunye nokuxhamla. Ngezantya ezithile, ngokuxhomekeka ngokuxhomekeke kwimithwalo ye-dynamics, i- motor stepper ingangena kwi-resonance kwaye ayikwazi ukuqhuba umthwalo.
Oku kubangela ukunyuka kweempawu, ama-motors agqityiweyo, ukugubha ngokugqithiseleyo kunye nengxolo.
Servo Limitations
Ii-motor motors ziyakwazi ukuhambisa amandla amaninzi kunama-stepper motors, kodwa zifuna i-circuit drive yinkqubo eninzi kunye neengxelo zemiqathango yokubeka indawo echanekileyo. Ii-motors ze-Servo nazo zibiza kakhulu kunama-stepper motors kwaye zihlala zikhuni ukufumana. Iimoto ze-Servo zihlala zifuna iibhokisi zegesi, ngakumbi kwi-speed speed operation. Imfuno yebhokisi yebhodi kunye nekhowudi yefowuni yenza i-servo motor icwangcise ngakumbi ngokukrakra kwaye inyuse iimfuno zokugcina kwenkqubo. Ukuphakamisa konke, ama-servo motors ayabiza ngakumbi kunama-stepper motors ngaphambi kokungena kwiindleko ze-encoder ye-position.
Isishwankathelo
Ukukhetha imoto engcono kwisicelo sakho kuxhomekeke kwiimpawu ezimbalwa zokupakisha kwenkqubo yakho kubandakanya iindleko, iimfuneko zokuchaneka kwithuba, iimfuno zephampu, ukufumaneka kwamandla okuqhuba, kunye neemfuno zokukhawuleza. Ngokubanzi, i-servo motors ibhetele kwizantya eziphakamileyo, izicelo ze-torque eziphezulu ngelixa ama-motors ahambayo afaneleke ngakumbi ukunyuka okufutshane, izicelo eziphezulu zokubamba iifowuni.
