Dab tsi yog qhov sib txawv ntawm servo tsav thiab servo motor?

Lub ntsiab servo tsav txhais:
Servo drives, tseem hu ua" servo controllers" thiab" servo amplifiers" ;, yog hom kev tswj hwm siv los tswj servo motors, uas ua zoo li cov inverters ntawm AC zoo tib yam thiab yog ib feem ntawm servo systems thiab feem ntau yog siv nyob rau hauv high-precision positioning systems. Feem ntau dhau ntawm txoj haujlwm, nrawm thiab lub zog ntawm peb txoj kev ntawm servo lub cev muaj zog tswj, kom ua tiav qhov ua haujlwm siab xa mus rau cov chaw ua haujlwm, tam sim no yog lub siab xa cov khoom siv thev naus laus zis.
Servo lub cev muaj zog txhais:
Servo lub cev muaj zog yog lub cav uas tswj cov kev ua haujlwm ntawm cov khoom siv cav hauv lub cev servo thiab yog cov twj siv hluav taws xob tsis ncaj rau lub tshuab tsav. Servo motors muaj peev xwm tswj kev ceev thiab txoj hauj lwm tseeb kom yog yog li qhov ntsuas hluav taws xob tuaj yeem hloov mus rau hauv torques thiab nrawm rau tsav tswj cov khoom. Servo lub cev muaj zog hlua taws yog tswj los ntawm lub teeb liab tawm tswv yim thiab tuaj yeem hloov kho sai, nyob rau hauv kev tswj tsis siv neeg, ua tus tswj kev ua haujlwm, thiab muaj cov yam ntxwv ntawm cov tshuab me thiab hluav taws xob lub sijhawm tas mus li, cov kab siab siab, tuaj yeem tau txais cov teeb liab hluav taws xob rau hauv lub cev muaj zog. kev khiav tawm lossis ad kaum tawm ceev. Muab faib ua dc thiab AC servo motors, cov yam ntxwv tseem ceeb uas yog thaum lub teeb liab voltage xoom, tsis muaj qhov tig rov qab tshwm sim, thiab qhov nrawm txo ntawm qhov ceev nrog qhov nce ntawm torque.
Yuav ua li cas servo tsav ua haujlwm:
Tam sim no, lub tshuab hluav taws xob servo siv lub teeb liab digital (DSP) ua lub hauv paus tswj, uas tuaj yeem paub qhov kev tswj hwm ntau dhau los, paub qhov digitalization, sib txuas thiab kev txawj ntse. Cov cuab yeej hluav taws xob feem ntau siv cov ntse lub zog hluav taws xob (IPM) raws li lub hauv paus tsim ntawm tsav Circuit Court, IPM integrated tsav Circuit, tib lub sijhawm muaj overvoltage, overcurrent, overheating, undervoltage thiab lwm qhov txhaum nrhiav thiab tiv thaiv Circuit Court, hauv Circuit Court tseem ceeb ntxiv mos muag pib kom txo tau qhov kev cuam tshuam ntawm kev pib txoj haujlwm ntawm kev tsav tsheb. Lub zog tsav ua ntej pib lub tswv yim hluav taws xob peb-theem hluav taws xob lossis lub zog hluav taws xob dhau los ntawm peb-theem tag nrho-tus choj txuas hluav taws xob, thiab tau txais cov hluav taws xob DC sib xyaw. Tom qab lub rectifier ntawm zoo peb-theem hluav taws xob lossis qhov tseem ceeb, thiab tom qab ntawd los ntawm peb-theem sine PWM voltage inverter zaus zaus kom tsav peb-theem haujlwm sib nqus synchronous AC servo lub cev muaj zog. Tag nrho cov txheej txheem ntawm lub zog tsav chav tsev tuaj yeem hais kom yooj yim rau AC-DC-AC cov txheej txheem. Lub ntsiab hluav taws xob sab saum toj ntawm cov xov txuas hluav taws xob (AC-DC) yog peb-theem tag nrho-tus choj tsis txaus.
Servo motors ua haujlwm li cas:
1. Servo mechanism yog kev tswj hwm tsis siv neeg uas ua kom cov khoom tawm ntawm qhov khoom' s txoj hauj lwm, txoj hauj lwm, xwm txheej, thiab lwm yam kom ua raws li kev hloov pauv ntawm cov hom phiaj (los yog muab tus nqi). Servo feem ntau cia siab rau cov pulses mus nrhiav cov chaw, hauv paus nws tuaj yeem nkag siab tias servo lub cev muaj zog txais 1 mem tes, yuav tig 1 mem tes coj lub kaum sab xis, thiaj li ua tiav qhov hloov chaw, vim hais tias servo lub cev muaj nws tus kheej muaj kev ua haujlwm ntawm tawm cov pulses, yog li servo motor txhua qhov kev sib hloov ntawm lub kaum ntse ntse, yuav tawm cov xov tooj sib xws ntawm cov pulses, yog li, thiab cov pulses tau txais los ntawm servo lub cev muaj zog ua lub ncha, lossis kaw lub voj, kom lub kaw lus yuav paub tias muaj pes tsawg tus xa mus rau servo motor, thiab ntawm tib lub sij hawm muaj ntau npaum li cas pulses tau txais rov qab, yog li qhov kev sib hloov ntawm lub cev muaj zog tuaj yeem tswj tau qhov tseeb, kom ua tiav qhov chaw raug, tuaj yeem ncav cuag 0.001mm. DC servo motors tau muab faib ua qhov txhuam hniav thiab txhuam tsis tau. Txhuam lub cev muaj zog tus nqi qis, cov qauv yooj yim, pib loj torque, dav dav ntau yam, tswj tau yooj yim, txij nkawm yog qhov xav tau, tab sis txij nkawm tsis yooj yim (txhuam cov roj), hluav taws xob cuam tshuam, ib puag ncig xav tau. Nws yog li nws tuaj yeem siv rau hauv tus nqi-rhiab dav dav kev lag luam thiab kev thov neeg pej xeem. Brushless lub cev muaj zog me me, lub teeb yuag, lub zog loj, kev teb ceev ceev, kev kub ceev, me me tsis muaj zog, kev sib hloov du, ruaj khov torque. Kev tswj hwm yog qhov nyuaj, yooj yim kom paub cov txawj ntse, nws txoj kev hloov pauv hluav taws xob yog hloov tau, tuaj yeem hloov pauv yoj lossis sine yoj pauv. Lub cev muaj zog tu-dawb, ua haujlwm siab, qis ua haujlwm kub, hluav taws xob hluav taws xob muaj tsawg heev, lub neej ntev, tuaj yeem siv rau hauv ntau qhov chaw ib puag ncig.
2, AC servo motor tseem yog brushless lub cev muaj zog, muab faib ua synchronous thiab asynchronous lub cev muaj zog, kev tswj txav feem ntau siv synchronous lub cev muaj zog, nws lub zog ntau yog loj, tuaj yeem ua tau ntau lub zog. Loj inertia, qhov siab tshaj plaws kev sib hloov ceev, thiab ceev ceev txo thaum lub zog nce. Nws yog vim li no haum rau cov ntawv thov uas khiav ntseeg nkaws ntawm lub nrawm.
3, lub rotor hauv servo lub cev muaj zog yog cov hlau nplaum ruaj khov, tus tsav tsheb tsav U / V / W peb-theem hluav taws xob tsim hluav taws xob hauv lub cev, lub rotor hauv lub luag haujlwm ntawm qhov chaw sib nqus no, thaum lub cev muaj zog' s tus kheej encoder tawm tswv yim teeb liab rau tus neeg tsav tsheb, tus tsav tsheb raws li cov lus pom tus nqi thiab lub hom phiaj tus nqi sib piv, kho lub kaum sab xis ntawm kev sib hloov rotor. Qhov tseeb ntawm servo lub cev muaj zog yog nyob ntawm qhov tseeb ntawm qhov ntsuas ntawm cov xov tooj (cov naj npawb ntawm cov kab). Kev ua haujlwm sib txawv ntawm AC servo lub cev muaj zog thiab lub tshuab hluav taws xob DC servo motor: AC servo zoo dua vim tias nws sine yoj tswj thiab lub zog loj yeej me me. DC servo yog nthwv dej trapezoidal. Tab sis DC servo yog yooj yim dua thiab pheej yig dua.
