Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm DC Servo Motors?

DC servo motors kuj tau dhau los ua ntau dua tam sim no, thiab lawv cov kev siv tau dav heev. Yog li dab tsi zoo nws muaj rau ntau lub lag luam xaiv? Dab tsi yog qhov tsis zoo?

DC servo lub cev muaj zog muaj cov yam ntxwv hloov kho tau zoo thiab lub sijhawm teb ceev ceev. Qhov zoo: Kev tswj ceev ceev, cov yam ntxwv nyuaj torque-ceev, yooj yim tswj txoj cai, siv tau yooj yim thiab pheej yig. Qhov tsis zoo: Cov kev tswj xyuas yog qhov nyuaj dua, cov tsav tsheb yuav tsum tau hloov kho ntawm qhov chaw los txiav txim siab PID tsis, thiab yuav tsum muaj kev sib txuas ntxiv.

Qhov zoo:

1) Qhov loj me me / lub teeb yuag, thiab kev ua haujlwm siab, lub teeb lub teeb tuaj yeem nyob ze li ntawm 90 feem pua;

2) tuaj yeem ua haujlwm nyob rau hauv qis qis, ua kom yooj yim;

3) Siv cov hlau nplaum ua haujlwm ruaj khov kom muaj peev xwm ncav cuag tus nqi / siab zog;

4) Tus nqi ntawm servo lub cev muaj zog thiab servo tsav yog pheej yig;

5) Cov haujlwm tseem ceeb xws li kev sib hloov qhov tseeb ntawm cov tshuaj tiv thaiv thiab qhov chaw ua haujlwm yog siab heev.

6) Resonant thiab vibration-dawb ua haujlwm. Lub inertia torque piv yog qhov loj, uas tuaj yeem nrawm nrawm nrawm. "Reserved" muaj peev xwm muaj zog, txuas ntxiv 2-3 lub sijhawm ntawm lub zog, lub sijhawm luv; nrog "tso tseg" torque, 5 mus rau 10 npaug ntawm qhov ntsuas torque hauv lub sijhawm luv luv. cia txias

7) Lub cev muaj zog yog proportional rau lub load tam sim no noj. suab nrov

8) Kev pib ua haujlwm tau zoo thiab kev tswj xyuas ceev, kev tswj ceev nrawm, ruaj khov, muaj peev xwm ntau dua, cuam tshuam los ntawm electromagnetic cuam tshuam.

9) DC ntawm DC lub cev muaj zog yog qhov txuag hluav taws xob ntau dua thiab ib puag ncig zoo dua li AC.

Qhov tsis txaus:

1) Nws yog ib qho tsim nyog los kho cov servo raws li qhov xav tau ntawm cov khoom thauj;

2) Yuav muaj cov hmoov txhuam txhuam thiab siv tsis tau rau hauv ib puag ncig huv;

3) Cov txhuam hniav yuav tsum tau noj thiab yuav tsum tau saib xyuas: cov txheej txheem nyuaj txwv qhov kev txo qis ntxiv ntawm qhov ntim thiab qhov hnyav ntawm DC lub cev muaj zog, tshwj xeeb tshaj yog cov zawv zawg sib cuag ntawm cov txhuam hniav thiab cov commutator ua rau txhua yam hnav thiab sparks, ua rau DC lub cev muaj zog ntau faulty. , Tsis tshua muaj kev ntseeg siab, lub neej luv, kev ua haujlwm hnyav. Lub commutation spark tsis tsuas yog ua rau hluav taws xob corrosion ntawm lub commutator, tab sis kuj yog ib qhov chaw ntawm xov tooj cua cuam tshuam, uas yuav muaj teeb meem rau cov khoom siv hluav taws xob nyob ib puag ncig. Qhov loj dua lub peev xwm ntawm lub cev muaj zog thiab qhov siab dua, qhov teeb meem loj dua yuav yog

Txawm hais tias DC servo lub cev muaj qhov tsis xws luag los ntawm kev sib cuag ntawm cov txhuam hniav thiab cov commutator, qhov kev ua haujlwm yooj yim tuaj yeem phim cov kev sib txuas lus servo lub cev muaj zog, thiab cov khoom siv hluav taws xob kuj zoo sib xws. Tsis tas li ntawd, kev paub thiab kev tsim tshuab ntawm DC servo motors thiab servo amplifiers muaj ntau yam sib xws nrog AC servo motors. Nws tseem tsim nyog xaiv DC servo lossis AC servo raws li lawv tus kheej xav tau.
