Dab tsi yog servo?
Lo lus Servo Servo los ntawm Latin "servus", uas txhais tau hais tias tus tub qhe ua raws li cov lus qhia ntawm tus tswv thiab ua haujlwm ncaj ncees thiab nrawm.
Dab tsi yog servo system?
Lub servo system, tseem hu ua lub hauv paus system, yog ib qho kev tawm tswv yim tswj kev siv los ua kom raug raws li lossis rov tsim dua ib qho txheej txheem. Lub servo system yog ib qho kev tswj tsis siv neeg uas tso cai rau cov zis tswj kom muaj nuj nqis ntawm qhov khoom qhov chaw, kev taw qhia, lub xeev, thiab lwm yam kom ua raws li kev hloov pauv ntawm lub hom phiaj nkag (los yog muab tus nqi). Nws lub luag haujlwm tseem ceeb yog txhawm rau nthuav dav, hloov pauv thiab tswj lub zog raws li qhov yuav tsum tau ua ntawm kev tswj hwm cov lus txib, kom lub zog torque, ceev thiab txoj haujlwm tso tawm los ntawm lub tshuab tsav tuaj yeem tswj tau yooj yim thiab yooj yim. Lub servo system muaj peb yam: xws li, lub zog tsav ntaus ntawv thiab lub cev muaj zog.
Dab tsi yog servo tsav?
Servo drives (servo drives), tseem hu ua "servo controllers" thiab "servo amplifiers", yog ib hom ntawm cov maub los siv los tswj servo motors. Nws muaj nuj nqi zoo ib yam li cov zaus converter ntawm ib qho yooj yim AC lub cev muaj zog. Nws yog ib feem ntawm lub servo system thiab feem ntau yog siv nyob rau hauv high-precision positioning systems. Feem ntau, servo lub cev muaj zog yog tswj los ntawm peb txoj haujlwm ntawm txoj haujlwm, ceev thiab lub zog kom ua tiav qhov kev ua haujlwm siab ntawm cov kab ke sib kis. Tam sim no nws yog ib qho khoom siv high-end ntawm kev sib kis technology.

Tam sim no, mainstream servo drives siv cov teeb liab digital processors (DSP) raws li cov tub ntxhais tswj, uas tuaj yeem paub txog kev tswj cov txheej txheem nyuaj thiab paub txog digitization, networking thiab txawj ntse. Cov cuab yeej hluav taws xob feem ntau siv cov tsav hluav taws xob tsim nrog lub tshuab hluav taws xob ntse (IPM) ua lub hauv paus. Pib lub voj voog kom txo tau qhov cuam tshuam rau tus neeg tsav tsheb thaum lub sijhawm pib.
Lub hwj chim tsav tsev ua ntej kho cov tswv yim peb-theem fais fab lossis lub zog loj los ntawm peb-theem puv-bridge rectifier circuit kom tau txais DC lub zog sib xws. Tom qab kho peb-theem hluav taws xob lossis hluav taws xob tseem ceeb, peb-theem ruaj khov hlau nplaum synchronous AC servo lub cev muaj zog yog tsav los ntawm kev hloov pauv zaus ntawm peb-theem sinusoidal PWM voltage hom inverter. Tag nrho cov txheej txheem ntawm lub zog tsav tsheb tuaj yeem hais tau yooj yim yog cov txheej txheem ntawm AC-DC-AC. Lub ntsiab topological Circuit Court ntawm lub rectification unit (AC-DC) yog ib tug peb-theem puv-bridge uncontrolled rectification circuit.
