1 stepper lub cev yog ib qho qhib-loop servo suab lus uas siv ntawm cov ntsiab lus tswj cov mem tes, qhov tso tawm sab nrauv. Piv nrog rau AC servo tsav thiab DC servo lub cev, nws qhov zoo tshaj plaws yog tus nqi qis, thiab tsis muaj txuam nrog kev yuam kev. Txawm li cas los xij, lub cav tsheb khiav hauv tsev muaj ntau qhov kev tsis txaus, xws li qeeb oscillation, suab nrov, kev daws teeb meem tsis siab, tab sis kuj tseem txwv tsis pub muaj cov ntaub ntawv ntawm kev tsav tsheb.
Qhov kev ua tau zoo ntawm tus tsav tsheb yog ze ze rau nws tus neeg tsav tsheb stepper, uas yuav muaj peev xwm kov yeej cov kev tsis haum ntawm lub cav ntaiv los ntawm kev txhim kho kev tsav tsheb. Piv nrog rau lwm txoj kev tsav tsheb, kev tsav tsheb me me tsis tuaj yeem txo qhov Stepper Tsav Nqus Tshem Tawm, txhim kho qhov kev daws teeb meem, thiab txo tau lossis tshem tawm qis qis qis, lub cev qis dua tus khauj khaum thiab khov kho.
Feem ntau, qhov kev tswj hwm ntawm kev tsav yog qhov zoo tshaj plaws. Vim tias nquag siv cov tshuab tsis tshua muaj zog stepper servo system tsis muaj kev tawm tswv yim los ntawm cov lus taw qhia, yog li ntawm qhov tsav lub zog nce nws cov kev tswj tam sim no sib txuas txo, ua rau muaj qhov tshwm sim tsis zoo. Li ntawd, qhov ceev thiab raug raws ntawm lub teb yog tsis siab, nws daim ntawv thov yog ntau heev
Kev tsav tsheb yog qhov kev txiav txim siab, lub subdivision yog tus neeg tsav tsheb yuav muab los ntawm lub siab tshaj plaws rau txhua tus mem tes raws li tus tsav teeb ntawm qhov kev sib tshooj coefficient muab faib rau cov coefficient pulse cov zis, ua piv txwv hais txog theem ob hom ntawm 200 pulses, yog tus tsav tsheb tsav Subdivided rau hauv 32, ces tus neeg tsav tsheb stepper tsav tsheb yuav tsum tau tso tawm 6400 pulse stepper motor tig ib ncig. Feem ntau raug faib ua 2,4,8,16,32,62,128,256,512 ....
Hauv cov teb chaws txawv teb chaws, rau qhov kev ua theem tshiab, feem ntau yog siv ob theem zuj zus thiab cov tsav tsheb sib luag. Tab sis nyob hauv lub tebchaws, feem ntau ntawm cov neeg siv ntawm "kev puas tsuaj" tsis yog kev to taub tshwj xeeb, thiab qee cov neeg xav tias qhov kev sib tawg yog txhawm rau txhim kho qhov tseeb, nws tsis yog qhov tseeb, qhov kev sib tawg yog qhov ua kom zoo dua qub.
Nws yog piav raws li nram no: tus tsav tsheb khiav tswj hwm yog tswj tau los ntawm tus neeg tsav tsheb mus rau stepper motor theem tam sim no kom ua tiav, mus rau ob theem phom, piv txwv li, yog tias lub tshuab ntsuas phom tam sim no 3A, yog hais tias siv cov khoom nruab nrog (xws li (feem ntau yog siv cov chopping tam sim no tam chopping hom) tsav tsav, lub cav khiav txhua theem, qhov tam sim no hauv qhov kev sib tw yuav hloov ntawm 0 mus rau 3A los yog los ntawm 3A rau 0, hloov tam sim no, yuav tsis ua kom lub cav khiav lub vibration thiab suab nrov.
Yog tias siv lub tshuab tsav, qhov kev tsav tsheb yog tsav hauv 10-lub xeev. Lub tshuab muaj hloov me ntsis tam sim no hauv kev sib tw ntawm 0.3A tsuas yog siv 3A, thiab cov kev hloov tam sim no nrog cov teebmeem sinusoidal. Txhim kho lub zog thiab lub suab nrov, yog li ntawd, qhov kev ua tau zoo dua yog qhov ua kom zoo dua ntawm cov khoom me me. Ua tus tsav tsheb kom ncaj nraim tswj lub tsheb theem tam sim no, yog li tus neeg tsav tsheb stepper tsav tsheb kom muaj cov txheej txheem heev thiab cov txheej txheem yuav tsum tau, tus nqi yuav siab dua.
tias qee tus tsav tsheb yuav siv "tus" los hloov cov khoom me me, thiab qee leej kuj paub tias kev rhuav tshem, tab sis qhov no tsis yog qhov kev sib tawg, vam tias feem ntau cov neeg siv yuav tsum paub qhov txawv ntawm ob qhov sib txawv:
1. "Smooth" tsis precisely tswj lub cav theem tam sim no, tab sis qhov hloov ntawm qhov tam sim no tus nqi ntawm qeeb qeeb, yog li "tus" tsis tsim cov micro-kauj ruam, thiab qis me ntsis ntawm cov kauj ruam yuav siv tau kom yog nrhiav.
2. Lub cav xaib tam sim no yog sib npaug, yuav ua rau lub cev muaj zog lub zog kom poob, thiab qhov kev tswj hwm tswj yuav tsis tsuas ua rau lub cev qeeb poob, ntawm qhov tawm tsam, lub zog yuav nce
