Ukukhetha phakathi kwe-servo motor kanye ne-stepper motor kungaba inselele enkulu ehilela ukulingana kwezici eziningana zokuklama. Ukubheka izindleko, i-torque, isivinini, ukusheshisa, nokushayela okuhambayo konke kudlala indima ekukhetheni imoto engcono kakhulu yesicelo sakho.
Ukwahlukana Okuyisisekelo Phakathi Kwe-Stepper ne-Servo Motors
Ama-Stepper nama-servo motors ahluke ngezindlela ezimbili eziyinhloko, ekwakheni kwawo okuyisisekelo nokuthi zilawulwa kanjani. Ama-Stepper motors anenqwaba yezibonda, izibini zamagnetic ezisenyakatho naseningizimu ezenziwe ngamagnet okuhlala unomphela noma umbane kagesi, ngokuvamile izigxobo ezingu-50 kuya ku-100. Uma kuqhathaniswa, ama-servo motors anezimbongolo ezimbalwa kakhulu, ngokuvamile eziyi-4 kuya kwezingu-12 zizonke. I-pole ngayinye inikeza indawo yokumisa yemvelo ye-shaft motor. Inombolo enkulu yamapulisi ivumela imoto ye-stepper ukuba ihambisane ngokunembile kanye ngqo phakathi kwesigxobo ngasinye futhi ivumela umqhubi ukuba aqhutshwe ngaphandle kwempendulo yesimo sezinhlelo eziningi zokusebenza. Ama-servo motors avame ukufuna i-encoder ye-position ukugcina ithrekhi yesikhundla se-shaft motor, ikakhulukazi uma kudingeka ukunyakaza okuqondile.
Ukushayela i-stepper motor endaweni ecacile kulula kakhulu kunokushayela imoto ye-servo. Ngomshayeli we-stepper, ukushayela okukodwa kuyodlulisela isithuthuthu esisodwa isinyathelo, kusukela kwesinye kuya kwesinye. Njengoba usayizi wesinyathelo wezimoto ezinikeziwe kuqondiswe ngesilinganiso esithile sokujikeleza, ukuthuthela esimweni esicacile nje umbuzo wokuthumela inombolo efanele yamapulsi. Ngokuphambene ne-servo motors bafunde umehluko phakathi kwesimo samanje se-encoder kanye nesimo abayalelwe kuso futhi nje kuphela okwamanje okudingekile ukuhambisa endaweni efanele. Ngomshini we-digital wedijithali wanamuhla, ama-stepper motors kulula ukulawula kunama-servo motors.
Izinzuzo ze-Stepper
I-stepper motors inikeza izinzuzo ezimbalwa ngaphezu kwe-servo motors ngaphesheya kwenani elikhulu lamapulangwe futhi kulula ukulawula ukulawula. Umklamo we-stepper motor unikeza i-torque yokubamba njalo ngaphandle kwesidingo sokuba injini ifakwe amandla. I-torque yesitimela se-stepper ngesivinini esincane sikhulu kune-servo motor yobukhulu obufanayo. Enye yezinzuzo ezinkulu kakhulu ze-stepper motors yizindleko zabo eziphansi kakhulu nokutholakala.
Izinzuzo ze-servo
Ngezinhlelo zokusebenza lapho kuvunyelwe khona ijubane eliphezulu ne-torque ephakeme, ama-servo motors akhanye. Ama-Stepper motors agxila ngokuzungeze okusheshayo kwe-RPM engu-2 000, kanti ama-servo motors atholakala izikhathi eziningi ngokushesha. Ama-servo motors nawo alondoloza ukulinganisa kwe-torque ngesivinini esikhulu, kuze kube ngu-90% we-torque elinganisiwe itholakala ku-servo ngesivinini esikhulu. Ama-servo motors nawo asebenza kahle kakhulu kunama-stepper ama-motors asebenza kahle phakathi kuka-80-90%. I-servo motor inganikezela kabili isibani sayo esilinganisiwe ngezikhathi ezincane, inikeze umthombo wamandla okudweba kusukela lapho kudingeka. Ngaphezu kwalokho, ama-servo motors akhona, atholakalayo ku-AC ne-DC drive, futhi ungadlidliza noma unenkinga ye-resonance.
Izinqamuleli ze-Stepper
Kuzo zonke izinzuzo zabo, ama-stepper motors anemikhawulo embalwa engabangela izinkinga ezinkulu zokuqalisa nokusebenza ngokuya kwesicelo sakho. Ama-Stepper motors awunawo amandla okugcina. Eqinisweni, ama-stepper ama-motors alahlekelwa umthamo omkhulu we-torque yawo njengoba esondela esiphezulu sokushayela umshayeli. Ukulahlekelwa kuka-80% we-torque elinganisiwe ku-90% wejubane eliphezulu kakhulu. Ama-Stepper motors nawo awafani nama-servo motors ekusheshiseni umthwalo. Ukuzama ukusheshisa umthwalo okusheshayo lapho u-stepper engeke akhiqize khona i-torque eyanele ukuhambisa isinyathelo esilandelayo ngaphambi kokushayela kwe-drive okulandelayo kuzoholela esiteji esinqamukile nokulahlekelwa esikhundleni. Uma ukuchithwa kwesimo kubalulekile, noma ngabe umthwalo on motor kumele ungalokothi udlule i-torque yayo noma i-stepper kumele ihlanganiswe ne-encoder ye-position ukuqinisekisa ukuchithwa kwesikhashana. Ama-Stepper motors nawo ahlushwa izinkinga zokudumala nokuhlaselwa. Ngezivinini ezithile, ngokuyinhloko kuxhomeke emithonjeni yemithwalo, isithuthuthu se- stepper singangena ku-resonance futhi singakwazi ukuqhuba umthwalo.
Lokhu kubangele izinyathelo ezingenqamuki, ama-motors aqinekile, ukudlidliza ngokweqile nomsindo.
Ukulinganiselwa kwe-Servo
Ama-servo motors akwazi ukuletha amandla amaningi kunama-stepper motors, kodwa adinga ukujikeleza okuningi okuyinkimbinkimbi futhi impendulo yempendulo yokubeka kahle. Ama-servo motors nawo ayabiza kakhulu kunama-stepper motors futhi ngokuvamile avame ukuthola. Ama-servo motors avame ukufuna amabhokisi amagoli, ikakhulukazi ekusebenzeni ngesivinini esincane. Imfuneko yebhokisi legiar kanye ne-encoder ye-position yenza i-servo motor iklanyelwe ngokunye okunomshini futhi yandisa izidingo zokugcina zesistimu. Ukuze uqede konke, ama-servo motors ayabiza kakhulu kunama-stepper motors ngaphambi kokungeza ezindleko zekhodi ye-position.
Isifingqo
Ukukhetha i-motor engcono kakhulu yesicelo sakho kuncike ezinkambisweni ezimbalwa zokuklanywa kohlelo lwakho kuhlanganise nezindleko, izidingo zokunemba kwezethulo, izidingo zomzuzu, ukutholakala kwamandla kagesi, kanye nezidingo zokusheshisa. Ngokuvamile, ama-servo motors angcono kakhulu ngejubane eliphakeme, izinhlelo zokusebenza ze-torque eziphezulu ngenkathi ama-stepper ama-motors afaneleka kangcono ukusheshisa okuphansi, izicelo eziphezulu zokubamba i-torque.
