Kev Sib Tham Txog Kev Tswj Cov Hluav Taws Xob ntawm Kev Tiv Thaiv Tsav Tsheb
Lub cav piv txwv yog ib qho cuab yeej ua rau lub teeb meem hluav taws xob hloov mus rau qhov chaw xa tawm los yog txoj kev xa tawm. Yog tias tsis muaj kev tshaj lij, qhov ceev thiab nrug ntawm qhov kev ua haujlwm ntawm lub cav ntog yog nyob ntawm seb muaj pes tsawg zaus thiab tswj kev tswj hluav taws xob.
Nws cov kev tswj yog raug txiav txim siab los ntawm ob yam:
1. Lub cav ntawm txhua kauj ruam ntawm cov kauj ruam hauv kauj ruam yog coj los piv txwv ntawm 2-phase hybrid stepping motor. Lub kauj ruam ntawm 200 kauj ruam kauj ruam yog: 360 ° / 200 = 1.8 ° yam tsis muaj splitting. Ntawd yog qhov tsawg kawg nkaus nyob deb li cas tias lub kauj vab stepping ib leeg yog 1.8 °. Txawm li cas los xij, hauv kev siv tiag tiag, cov kauj ruam yog feem ntau raug faib. Nqa ob nqe lus me me ua piv txwv. Lub sij hawm no, lub kauj ruam hauv kauj ruam yog ob kauj ruam, uas zoo ib yam li thawj kauj ruam. Tam sim no tus kauj ruam ntawm tus kauj ruam yog: 360 ° / (200 * 2) = 0.9 °; zoo ib yam, nyob rau hauv tshooj 4, Ib kauj ruam: 360 ° / (200 * 4)
= 0.45 °; 8 seem, kauj ruam nkaus xwb: 360 ° / (200 * 8) = 0.225 °; 16 seem, kauj ruam nkaus xwb: 360 ° / (200 * 16) = 0.1125 °; Hauv tshooj 32, cov kauj ruam yog 360 ° / (200 * 32) = 0.05625 °. Yog li, hauv qab ntawm kev tsav tsheb, qhov kev ua qoj hlau yog ib kauj ruam ntawm cov kauj ruam ntawm kauj ruam yog: 360 / (kauj ruam tsav qiv tus naj npawb * qiv zauv).
Nws tuaj yeem pom tau hais tias kom txo tau lub kauj ruam ntawm lub kauj ruam ntawm tus kauj ruam ntawm kev ua haujlwm kom ua tiav siab dua, nws yuav tsum pib ntawm ob qho. Ib qho yog nce lossis txais yuav ib lub kauj vab hlau stepping nrog cov kauj ruam ntxiv mus kom tau ib kauj ruam me me. Lub kaum sab xis pom, xws li 0.9 °. Qhov thib ob yog kom nce qib ntawm kev rhuav tshem.
2. Muab xam qhov tseeb. Thaum tswj lub cav ntiv tes mus ua haujlwm, lub zog yuav tsum xyuas kom meej tias qhov kev xam qhov tseeb yog siab dua qhov theem ntawm lub cav ntaiv cov kauj ruam thaum hloov qhov kev xa tawm los yog txoj kab xa mus rau hauv cov kauj ruam qis. Piv txwv, lub kauj ruam pib ntawm lub kauj ruam ntawm kauj ruam yog 0.1125 ° rau ib kauj ruam, qhov kev xa tawm ntawm qhov yuav tsum tau tsiv yog 143.45 °, thiab cov kauj ruam yuav tsum yog = 143 ° / 0.1125 °, thiab qhov tshwm sim yog 1273.11. .... kauj ruam, Qhov tseeb tshwm sim yog 1275 cov kauj ruam, thiab qhov yuam kev yuam kev yog: 0.11111 * 0.1125
= 0.0125 °. Yog hais tias qhov kev xa tawm ntawm qhov kev sib txig sib luag yog nyob rau hauv 1 °, 143.45 ° = 143 °, qhov khoo feem ntau yog muab pov tseg. 143 / 0.1125 = 1271.1111 kauj ruam, ces muab piv rau yav dhau los, qhov yuam kev yog: (1275-1271) * 0.1125 °
= 0.45 °. Qhov laj thawj yog vim li cas qhov no tau npaj tseg ntawm no yog vim nyob hauv qhov nruab nkag, vim yog qhov kev txwv ntawm cov ntaub ntawv, yog qhov muab xam tsis siv siv ntab los yog ob zaug, feem ntau qhov feem cuam pov tseg, ua rau muaj kev sib tw loj.
Stepper lub cev yuav siv los ua ib lub cav nyiaj txiag, txau tshuab cav, tshuab ntaus ntawv tsav tsheb, kev tswj lub cev muaj zog.
