Iinjini ezahlukeneyo ziyafuneka kwiinkalo ezininzi, kubandakanywa nezaziwayoiinjini zokunyathelakunye neenjini ze-servo. Nangona kunjalo, kubasebenzisi abaninzi abawuqondi umahluko ophambili phakathi kwezi ntlobo zimbini zeenjini, ngoko abazi ukuba bakhethe njani. Ngoko ke, yintoni umahluko omkhulu phakathiiinjini zokunyathelakunye neenjini ze-servo?
Servo motor
1. Umgaqo wokusebenza
Ezi motors zimbini zahluke kakhulu kumgaqo, i-stepper motor luphawu lwepulse yombane ukuya kwindawo yokufuduswa kwe-angular okanye ukufuduswa komda kwindawo evulekileyo yolawulo lwento ye-stepper motor, jonga umgaqo wokusebenza we-stepper motor.
Kwaye i-servo ikakhulu ixhomekeke kwi-pulse kwindawo, i-servo motor ngokwayo inomsebenzi wokuthumela i-pulses, ngoko i-servo motor yonke ukujikeleza kwe-angle, iya kuthumela inani elihambelanayo le-pulses, ukuze, kunye ne-servo motor ukwamkela i-pulse yenze i-echo, okanye i-loop evaliweyo, ukwenzela ukuba inkqubo iya kucaca ukuba zingaphi ii-pulses ezinokuthi zithumele kwaye zifumane umva. ukufikelela kwindawo echanekileyo.
2, Ukulawula ukuchaneka
Ukuchaneka kwemoto ye-stepper ngokuqhelekileyo kufezekiswa ngolawulo oluchanekileyo lwe-angle yesinyathelo, enezixhobo ezininzi zokwahlulahlula ukufezekisa ulawulo oluchanekileyo.
Ukuchaneka kolawulo lwemoto ye-servo kuqinisekiswa yi-encoder ejikelezayo ngasemva kwe-motor shaft, kwaye ukuchaneka kokulawulwa kwe-servo motor ngokubanzi kuphezulu kune-stepper motor.
3, Isantya kunye nomthamo ogqithisiweyo
I-Stepper motor kwi-low-speed vibration ithanda ukungcangcazela okuphantsi, ke xa i-stepper motor ikwisantya esisezantsi, ihlala ifuna ukusebenzisa itekhnoloji yokudambisa ukoyisa isenzeko sokungcangcazela okuphantsi-frequency, njengokongeza iidampers kwi-motor okanye ukuqhuba usebenzisa itekhnoloji yokwahlulahlula, njl. ukusebenza ngesantya esiphezulu ukugcina ukusebenza okugqwesileyo. Iimpawu zomzuzu wokuphindaphinda kwezi zimbini zahlukile, kwaye ngokubanzi isantya esilinganiselweyo se-servo motor sikhulu kuneso sinyathela motor.
I-torque ye-torque ye-stepper motor iyancipha njengoko isantya sikhula, ngelixa i-servo motor iyimveliso ye-torque engaguqukiyo, ngoko ke i-motor ye-stepper ayinakho ukulayisha ngaphezulu, ngelixa i-AC servo motor inamandla okulayisha ngaphezulu.
4. Ukusebenza okusebenzayo
Iinjini ze-Stepper ngokubanzi zinolawulo oluvulekileyo lwe-loop, kwimeko ephezulu kakhulu i-frequency yokuqala okanye enkulu kakhulu umthwalo uya kuba ngaphandle kwenyathelo okanye i-plugging phenomenon, ngoko ke ukusetyenziswa kwesidingo sokujongana nemiba yesantya okanye ukunyusa i-encoder evaliweyo yokulawula i-loop, jonga ukuba yintoni i-motor evaliweyo. Ngelixa ii-motor ze-servo zisebenzisa ulawulo oluvaliweyo, kulula ukulawula, akukho lahleko yenyathelo lenyathelo.
5, Iindleko
I-Stepper motor inenzuzo malunga nokusebenza kweendleko, ukufezekisa umsebenzi ofanayo kwimeko yexabiso le-servo motor inkulu kunamandla afanayo e-stepper motor, impendulo ephezulu ye-servo motor, isantya esiphezulu kunye neenzuzo zokuchaneka okuphezulu kugqiba ixabiso eliphezulu lemveliso, engenakuphepheka.
Isishwankathelo, iinjini ze-stepper kunye neenjini ze-servo zombini ukusuka kumgaqo wokusebenza, ukuchaneka kokulawula, umthamo ogqithisiweyo, ukusebenza okusebenzayo kunye neendleko kukho umahluko omkhulu. Kodwa ezi zimbini zineenzuzo zazo, abasebenzisi abafuna ukwenza ukhetho kubo kufuneka badibanise iimfuno zabo zangempela kunye neemeko zesicelo.
