Lub servo tsav ua haujlwm li cas:
Tam sim no, mainstream servo drives siv cov teeb liab teeb liab processors (DSP) raws li lub hauv paus tswj, uas muaj peev xwm paub txog cov complex tswj algorithms thiab paub digitization, networking thiab txawj ntse. Cov khoom siv hluav taws xob feem ntau txais yuav 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 zog tsav lub zog ua ntej kho cov tswv yim peb-theem fais fab lossis lub zog hluav taws xob 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.
Nrog rau daim ntawv thov loj ntawm servo systems, kev siv servo drives, servo tsav debugging, thiab servo tsav txij nkawm yog txhua yam teeb meem tseem ceeb rau servo drives niaj hnub no. Ntau thiab ntau lub tuam txhab tswj kev lag luam thev naus laus zis tau ua qhov kev tshawb fawb tob tob ntawm servo drives.
Servo drives yog ib feem tseem ceeb ntawm kev tswj cov lus tsa suab niaj hnub no thiab tau siv dav hauv cov khoom siv automation xws li kev lag luam robots thiab CNC machining chaw. Tshwj xeeb tshaj yog cov servo tsav siv los tswj AC mus tas li hlau nplaum synchronous lub cev muaj zog tau dhau los ua kev tshawb fawb hotspot hauv tsev thiab txawv teb chaws. Tam sim no, ceev, thiab txoj hauj lwm 3 kaw-voj tswj algorithms raws li vector tswj feem ntau yog siv rau hauv kev tsim ntawm AC servo drives. Txawm hais tias qhov ceev kaw-loop tsim nyob rau hauv no algorithm yog tsim nyog los yog tsis plays lub luag hauj lwm tseem ceeb nyob rau hauv kev ua tau zoo ntawm tag nrho cov servo tswj system, tshwj xeeb tshaj yog cov ceev tswj kev ua tau zoo.
Servo tsav system xav tau:
1. Dav ceev ntau yam
2. High positioning raug
3. Txaus kis tau tus mob rigidity thiab kev kub ceev stability.
4. Txhawm rau kom muaj txiaj ntsig zoo thiab ua haujlwm zoo,Ntxiv nrog rau qhov yuav tsum tau muaj qhov tseeb ntawm qhov chaw siab, cov yam ntxwv zoo teb ceev kuj tseem yuav tsum tau, uas yog, cov lus teb rau kev taug qab cov lus txib yuav tsum ceev ceev, vim tias CNC system yuav tsum tau ntxiv thiab rho tawm thaum pib thiab nres. Lub acceleration yog loj txaus kom shorten lub sij hawm hloov pauv ntawm lub feed system thiab txo cov contour hloov yuam kev.
5. Tsawg ceev thiab siab torque, muaj zog overload muaj peev xwm
Feem ntau hais lus, tus neeg tsav tsheb servo muaj lub peev xwm tshaj 1.5 zaug hauv ob peb feeb lossis ib nrab teev, thiab tuaj yeem dhau los ntawm 4 mus rau 6 zaug hauv lub sijhawm luv luv yam tsis muaj kev puas tsuaj.
6. Kev ntseeg siab
Nws yuav tsum tau hais tias lub tshuab pub tsav ntawm CNC tshuab cuab yeej muaj kev ntseeg siab, kev ua haujlwm zoo, muaj zog ib puag ncig hloov mus rau qhov kub, av noo, kev co, thiab muaj zog tiv thaiv kev cuam tshuam.
Cov kev xav tau ntawm servo tsav rau lub cev muaj zog:
1. Lub cev muaj zog tuaj yeem ua haujlwm tau zoo los ntawm qhov qis tshaj plaws mus rau qhov siab tshaj plaws, thiab qhov hloov pauv ntawm lub zog yuav tsum me me, tshwj xeeb tshaj yog nyob rau hauv qis qis xws li 0.1r / min lossis qis dua, tseem muaj qhov ceev ruaj khov yam tsis tau nkag.
2. Lub cev muaj zog yuav tsum muaj lub peev xwm loj dhau lub sijhawm ntev kom ua tau raws li qhov yuav tsum tau muaj ntawm kev ceev ceev thiab siab torque. Feem ntau, DC servo motors yuav tsum tau overloaded 4 mus rau 6 zaug hauv ob peb feeb yam tsis muaj kev puas tsuaj.
3. Yuav kom ua tau raws li qhov yuav tsum tau ua ntawm cov lus teb ceev ceev, lub cev muaj zog yuav tsum muaj lub sijhawm me me ntawm inertia thiab lub rooj muag khoom loj, thiab muaj lub sijhawm me me thiab pib voltage raws li qhov ua tau.
4. Lub cev muaj zog yuav tsum muaj peev xwm tiv taus ntau zaus pib, braking thiab thim rov qab.
