Tseem ceeb heev rau kev hloov pauv servo
Feem ntau, peb yuav tsum tau siv cov khoom siv hloov khoom pauv, xws li hloov lub cav uas twb muaj lawm nrog lub cav tshiab. Cov laj thawj yuav muaj xws li: cov khoom seem, cov nqi khaws nyiaj, tus me nyuam lub sij hawm , los yog kev hloov kho tshiab. Ntau qhov tseem ceeb yuav tsum tau xav txog thaum nws tuaj txog ntawm cov ntsiab lus ntawm txhua daim ntawv thov.
1. Kev noj qab nyob zoo
Txawm yog vim li cas koj thiaj xav hloov lub khoom muag, koj yuav tsum to taub thiab nco ntsoov ua ntej tshaj plaws: txo kev pheej hmoo. Ib qho kev hloov zoo tshaj plaws yuav txo tau txoj kev tuaj yeem ntsib thaum txheej txheem kev nce qib
tej zaum muaj teeb meem. Yog tias muaj kev pheej hmoo hauv kev hloov txoj haujlwm tsis zoo kiag li, qhov tsis zoo ntawm qhov system tsis ua haujlwm nce ntxiv. Yog li no, tus nqi yuav tsum tsis yog qhov kev txiav txim siab hauv qhov kev pab cuam hloov tshiab! Ib qho kev hloov zoo zoo tsis tsuas yog txo qhov kev pheej hmoo, tab sis kuj txo cov nuj nqi zog, es tsis txo cov nqi, tiam sis txais ntau dua cov kev pheej hmoo.
2. qhov phom sij ruaj khov
Inertia txuam yog qhov tseem ceeb heev, tab sis feem ntau nws tsis pom kev. Qhov kev siv rau kev hloov khoom siv yuav tsum muaj tib lub rotor inertia ua tus thawj servo, lossis ua kom zoo li zoo tau. Lub hom phiaj yog ua kom lub cev tom qab siv qhov kev pab tshiab
kev ruaj ntseg. Ntawm cov hoob kawm, qhov kev ntseeg no yog qhov tseemceeb tau mus txog qhov yuav tsum tau muaj kev ruaj ntseg. Yog tias koj xav hloov qhov kev daws teeb meem tsawg dua (xws li tus tachometer, thim rov qab encoder, los yog qub qub resolver hom system), feem ntau yog qhov kev daws teeb meem loj heev ntawm lub cev xauv (sinusoidal encoder feedback device) uas tsis muaj tsawg tshaj 220 kab ntawm ib kiv puag ncig (CPR). Flexibility yuav ntxiv nrog rau kev sib piv rotor inertia. Feem ntau, thaum siv cov cuab yeej siv high-resolution los txhim kho cov kev daws teeb meem, qhov kev hloov ntawm qhov kev hloov tshiab yuav tsum yog tsawg tshaj li ntawm ib feem peb ntawm thawj lub cav. Ntawm chav kawm, nws yog zoo dua mus ua ib nrab. Txoj kev no tau siv nyob hauv ntau qhov chaw.
3. ceev thiab torque
Kev ceev thiab lub zog sib txuas yog qhov sib npaug tseem ceeb. Kev ua tiav ntawm kev hloov lub cev yuav tsum ua kom tau lossis tshaj qhov kev ua tiav ntawm lub cav thawj. Tshawb nrhiav ob qhov catalog parameter qhov tseem ceeb (piv txwv li kev ua kom nrug, ceev ceev) kom paub tseeb tias tsis muaj qhov tsis xws luag.
Lub zog ntawm tus qauv yuav tsum piv rau ntau zog ntawm txhua lub cav. Comparing graphics yog ib qho kev pab cuam zoo heev los ntawm kev sib piv lub cev muaj zog / nqhuab curves thiab manually nyob rau hauv spreadsheets thim cov nqi yam. Piv txwv, lub ntsiab lus ntawm qhov sib nrauj ntawm 1000 PRM, Tsav A = X Nm thiab lub cev muaj zog B = Y Nm, thiab tib lub lag luam yog ua tiav tag nrho kev khiav ceev.
4. cav loj
Txawm hais tias qhov loj me me tsis tseem ceeb rau kev ua tiav ntawm lub cav, thaum lub sijhawm hloov txoj kev hloov, yog tias qhov kev pabcuam tshiab raug muab txuas rau qhov loj tib yam li lub cav thawj, nws yuav pab ua kom tiav qhov khiav. Yuav tsum tau soj ntsuam cov qauv kev kos duab ntawm ob lub tshuab kom paub meej. Txawm tias hloov lub cav uas siv cov qauv kev lag luam (xws li NEMA los yog ICE) yog txoj kev zoo. Cov kev cai tswjfwm feem ntau qhia txog qhov kev qhia ntawm qhov qhia txog qhov luaj li cas thiab lub nplhaib ciaj pua, tab sis feem ntau ntawm cov ncej loj feem ntau tsis ruaj. Piv txwv li, txawm tias koj hloov lub NEMA 34 lub cev, cov ntsiab lus tsim ntawm txhua lub chaw ua haujlwm yuav txawv heev!
5. lwm yam
Puas yog lub cev qev xwb uas tau hloov hauv lub tshuab? Feem ntau, hloov qhov kev pab cuam txhais tau hais tias hloov qhov tsav, cable, thiab qee tus neeg txawm hloov qhov xws li. nyob rau hauv cov xwm txheej no, kev sib txawv ntawm kev sib txawv kuj yog ib qho kev txiav txim siab thib ob yog tias ua raws li cov khw tsim nyog.
Txawm li cas los xij, yog tias hloov lub cav yuav raug siv nrog tus tsav qub, nws yuav tsum ua tib zoo kuaj xyuas. Piv txwv, rau cov ntaub ntawv khaws tseg (xws li lub cev muaj zog: Kt thiab Ke), cov hom khoom siv tswv yim thiab kev daws teeb meem thiab kab hlau txuas rau sab nraud, thiab lwm yam yuav tsum tau ua tib zoo kuaj thiab sib phim. Tsis tas li ntawd, txawv servo motor manufacturers feem ntau siv cov chav nyob thiab kev hloov dua siab tshiab rau cov ntsiab lus tseem ceeb no. Qhov no yuav tsis yooj yim kom paub qhov txawv ntawm qhov txhais thiab lub cav ntawm lub cav thaum sib piv cov txheej txheem. Tsab ntawv xov xwm no muab qee cov lus qhia pabcuam ntxiv rau qhov no, thiab qhia txog qee qhov kev xav hauv kev hloov pauv hloov.
