Ngaba uyawazi umahluko phakathi kwe-stepper motor kunye ne-servo motor?

Injini yeServo
1, Umgaqo wokusebenza
Ezi moto zimbini zahlukile kakhulu ngokwemigaqo, i-stepper motor sisignali yombane yokubetha ukuya kwindawo ejikelezayo okanye kwindawo ejikelezayo yecandelo le-open-loop control element stepper motor, jonga umgaqo wokusebenza we-stepper motor.

Kwaye i-servo ikakhulu ixhomekeke kwi-pulse ukuya kwindawo, i-servo motor ngokwayo inomsebenzi wokuthumela ii-pulses, ngoko ke i-servo motor nganye ejikelezayo ye-engile, iya kuthumela inani elihambelanayo lee-pulses, ukuze, kwaye i-servo motor yokwamkela i-pulse yenze i-echo, okanye i-closed loop, ukuze inkqubo icace ukuba zingaphi ii-pulses ezithunyelweyo nezamkelweyo zingaphi ii-pulses ezibuyileyo, ukuze ikwazi ukulawula ngokuchanekileyo ukujikeleza kwe-motor ukuze ifikelele kwindawo echanekileyo.

2, ukuchaneka koLawulo
Ukuchaneka kwe-stepper motor ngokubanzi kufezekiswa ngolawulo oluchanekileyo lwe-step angle, enegiya ezahlukeneyo zokwahlulahlula ukuze kufezekiswe ulawulo oluchanekileyo.

Ukuchaneka kolawulo lwemoto ye-servo kuqinisekiswa yi-rotary encoder engasemva kweshaft yemoto, kwaye ukuchaneka kolawulo lwemoto ye-servo ngokubanzi kuphezulu kunokwemoto ye-stepper.

3, Isantya kunye nomthamo wokugqithisa
I-Stepper motor esebenza ngesantya esiphantsi ithambekele ekungcangcazeleni okuphantsi, ngoko ke xa i-stepper motor isebenza ngesantya esiphantsi, idla ngokufuna ukusebenzisa iteknoloji yokudambisa ukuze yoyise isiganeko sokungcangcazela okuphantsi, njengokongeza ii-dampers kwi-motor okanye kwi-drive kusetyenziswa iteknoloji yokwahlulahlula, njl.njl., ngelixa i-servo motor ingekho kule meko, iimpawu zayo zolawulo oluvaliweyo zimisela ukusebenza kwayo ngesantya esiphezulu ukuze kugcinwe ukusebenza okugqwesileyo. Iimpawu ze-moment-frequency zezi zimbini zahlukile, kwaye ngokubanzi isantya esilinganisiweyo se-servo motor sikhulu kuneso se-stepper motor.

I-torque yokukhupha ye-stepper motor iyancipha njengoko isantya sisanda, ngelixa i-servo motor iyi-torque ephuma rhoqo, ngoko ke i-stepper motor ngokubanzi ayinayo i-overload, ngelixa i-AC servo motor inamandla okugqithisa kakhulu.

4, Ukusebenza okusebenzayo
Iimoto zeStepper zihlala zilawula i-open-loop, kwimeko yokuba i-frequency yokuqala iphezulu kakhulu okanye inkulu kakhulu, umthwalo uya kuba ngaphandle kwenyathelo okanye i-plugging phenomenon, ngoko ke ukusetyenziswa kwesidingo sokujongana nemiba yesantya okanye ukwandisa i-encoder closed-loop control, jonga ukuba yintoni i-closed-loop stepper motor. Ngelixa iimoto ze-servo zisebenzisa ulawulo lwe-closed-loop, kulula ukuzilawula, akukho lahleko ye-step phenomenon.

 5, Ixabiso

I-Stepper motor inenzuzo ngokwexabiso lokusebenza, ukuze kufezekiswe umsebenzi ofanayo kwimeko ye-servo motor, ixabiso lingaphezulu kune-stepper motor yamandla afanayo, impendulo ephezulu ye-servo motor, isantya esiphezulu kunye neenzuzo zokuchaneka okuphezulu zimisela ixabiso eliphezulu lemveliso, nto leyo engenakuphepheka.

Ngamafutshane, ii-stepper motors kunye nee-servo motors zombini ukusuka kumgaqo wokusebenza, ukuchaneka kokulawula, umthamo wokugqithisa, ukusebenza kunye neendleko kukho umahluko omkhulu. Kodwa ezi zimbini zineengenelo zazo, abasebenzisi abafuna ukukhetha kuzo kufuneka badibanise iimfuno zabo zokwenyani kunye neemeko zokusetyenziswa.
