Imoto yeservo iyafana nakwisithuthi esinyukayo ekusebenzeni nakwimeko, kodwa ukusebenza kweemoto ze-servo kwahluke kakhulu. Yintoni umahluko okhethekileyo? Uyintoni umahluko phakathi kwe-servo motor kunye ne-step motor ekusebenziseni izixhobo zomatshini ezichanekileyo?
Okokuqala, iimpawu ezihamba rhoqo ze-servo motor kunye ne-stepper motor zahlukile.
I-Stepper motor ithambekele ekungcangcazelweni okuhamba ngesantya esisezantsi. Umgaqo wokusebenza kwenyathelo lemoto umisela ukuba imeko ephantsi yokungcangcazela ayithandeki ekusebenzeni kwesiqhelo komatshini. Uninzi lwabaqhubi bamanyathelo bawabala ngokuzenzekelayo amanqaku abo okushukuma ukuze bahlengahlengise ialgorithm yolawulo ukucinezela ukungcangcazela kwabo.
Imoto ye-Ac servo ibaleka kakuhle, nkqu ngesantya esisezantsi ayizukuvela into yentshukumo. Inkqubo ye-Ac servo inomsebenzi wokucinezelwa kwengxolo, enokuthi yenzele ukungabikho kobungqongqo boomatshini, kwaye ine-frequency analytic function (FFT) ngaphakathi kwenkqubo, enokuthi ibone indawo yomatshini kwaye iququzelele uhlengahlengiso lwenkqubo.
Okwesibini, i-servo motor kunye ne-stepper motor performance yahlukile.
Ukulawulwa kwemoto yokunyathela kulawulo oluvulekileyo, ukuhamba rhoqo kuphezulu kakhulu okanye umthwalo mkhulu kakhulu, kwaye imeko ye-overshoot okanye i-overshoot kulula ukuvela xa isantya siphezulu kakhulu, ukuze kuqinisekiswe ulawulo lokuchaneka kwayo, iingxaki zokunyuka nokuhla kwesantya kufuneka kujongwane nazo kakuhle. Inkqubo yedrive drive ye-AC ivaliwe ngophawu lolawulo. Umqhubi unokuthoba ngokuthe ngqo isiginali yempendulo ye-encoder yemoto. Isangqa sokuma kunye nesangqa sesantya senziwa ngaphakathi. Ngokubanzi, akukho lahleko lwenyathelo okanye ukugqithisa kwimoto ehambayo, kwaye ukusebenza kolawulo kuthembekile.
Okwesithathu, iimpawu ezihamba rhoqo ze-servo motor kunye ne-stepper motor zahlukile.
Imveliso torque ye stepper yehla ngokunyuka kwesantya, kwaye iya kuncipha kakhulu kwisantya esiphezulu, ke isantya sokusebenza esiphezulu se-stepper motor ngokubanzi yi-300 ~ 600 RPM .. Isiphumo sokuhamba kwesithuthi esinyukayo siya kuncipha ngokukhawuleza kwisantya esiphezulu Imoto ye-AC servo yimveliso eqhubekayo ye-torque, oko kukuthi, ngaphakathi kwesantya sayo esilinganisiweyo (ngokubanzi i-2000 RPM okanye i-3000 RPM), inokuvelisa i-torque elinganisiweyo kunye nokukhutshwa kombane rhoqo ngaphezulu kwesantya esikaliwe.
Okwesine, ukuqhuba kwempendulo yesantya kunye nokuhamba kwendlela yokusebenza kwezithuthi kwahlukile.
Isithuthi esinyukayo sithatha i-200 ~ 400 milliseconds ukukhawulezisa ukusuka ekuphumleni ukuya kwisantya sokusebenza, zihlala zilikhulu kumzuzu ngomzuzu. Ukusebenza kokukhawulezisa inkqubo ye-AC servo kulungile. Ukuthatha iMingzhi 400 W AC servo motor njengomzekelo, kuthatha kuphela iimillisecond ezimbalwa ukukhawulezisa ukusuka kwi-static ukuya kwisantya sayo esikaliwe se-3000 RPM enokusetyenziselwa imeko yolawulo efuna ukuqala ngokukhawuleza nokumisa.
Kwezinye iimeko ezifuna kakhulu, ii-servo motors ezinokusebenza okuphezulu kakhulu kunee-stepper motors kufuneka zisetyenziswe. Nangona i-China inelona candelo ligqibeleleyo lezorhwebo emhlabeni, uninzi lwazo lusentsimini ye "bold and free", kwaye kusekho umsantsa omkhulu ekufumaneni imveliso ephezulu.
Okwesihlanu, i-servo motor kunye ne-stepper yokulawulwa kwemoto ngokuchaneka yahlukile.
I-engile yenyathelo lamanqanaba amabini e-hybride yokunyathela imoto yi-1.8,0.9, kwaye inqanaba lesihlanu le-motor ehambisayo li-0.72,0.36. Nangona kunjalo, ukuchaneka kolawulo lwe-AC servo motor kuqinisekiswe yikhowudi yokujikeleza emva komva wesithuthi. Imoto ene-encoder eyi-17 encinci, i
