Kev ua tau zoo yog feem ntau touted thiab feem ntau hu ua cliché, thiab txawm tias thaum nws siv los ua ib lo lus buzz, ntau tus engineers pov lub tswv yim tawm ntawm txoj kev ua ntej delving rau hauv qhov teeb meem.Txhua lub tuam txhab xav siv lo lus no, tab sis muaj pes tsawg leej txaus siab siv nws?Kev zoo yog tus cwj pwm thiab kev ua neej.Kev ua tau zoo yog ib qho yooj yim hais, tab sis nyob rau hauv cov ntaub ntawv no nws kuj yog ib yam dab tsi uas yuav piav nyob rau hauv txhua txhua kauj ruam ntawm tus tsim.Kev ua tau zoo, ua ntej thiab qhov tseem ceeb, yuav tsum tau ua tib zoo saib ntawm sab saum toj.Cov khoom tsim nyog lub cev muaj zog xav tau kev saib xyuas: zoo, kev xa khoom, thiab tus nqi (hauv lub xeev tsim), thiab yog tias koj tsom rau tus nqi, koj tuaj yeem muab cov neeg siv khoom zoo tshaj plaws yam tsis muaj kev tshaj lij.Qhov no txhais tau tias muaj ib qho kev daws teeb meem uas yooj yim dua los tsim thiab xa tawm.Tag nrho cov khoom yuav tsum tau sib xyaw ua ke thiab tus neeg muag khoom lub cev yuav tsum nkag siab lub hom phiaj thiab lub hom phiaj ntawm tus neeg siv tsim.
Cov neeg muag khoom lub cev muaj zog 'cov kev tswj hwm sab hauv feem ntau siv 4.5 sigma mus kom ze, thiab 6 sigma tsis yog qhov txaus siab rau cov neeg siv khoom tau paub los ntawm lawv cov khoom.Tsuas yog los ntawm kev tswj hwm nruj heev tuaj yeem ua kom ntseeg tau tias cov khoom xav tau, tsis yog rau kev tsim qauv.Nrog rau qhov system no tus neeg siv tau txais "lub cev muaj zog uas tsis tu ncua thiab ntseeg tau raws li cov kev xav tau tshwj xeeb hauv lub neej ntawm lub cev muaj zog".Lub hom phiaj no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv high-volume ntau lawm, qhov twg tag nrho cov kab sib dhos tuaj yeem yooj yim tuaj yeem nres vim cov khoom tsis xws luag.Txhawm rau kom ntseeg tau qhov zoo ntawm lub tuam txhab stepper motors, lawv tsom mus rau peb qhov tseem ceeb, cov khoom zoo, tsim zoo thiab kev tsim khoom zoo.
Kev xaiv ntawm cov neeg muag khoom ua lub luag haujlwm tseem ceeb hauv kev ciaj sia thiab kev loj hlob ntawm kev lag luam kev lag luam thiab kev tsim khoom, thiab yog ib feem tseem ceeb ntawm kev tswj cov saw hlau.Thaum xav txog cov khoom zoo, cov txheej txheem tsim khoom muaj ntau qhov sib dhos: stators, rotors, shafts, bearings, kawg caps, windings, leads, connectors, thiab lwm yam.Tsis tas li ntawd, txhua lub rooj sib txoos tuaj yeem muab faib ua cov khoom sib dhos xws li cov xov hlau, rwb thaiv tsev, vaj tse thiab cov ntsaws ruaj ruaj, cov khoom sib txuas, thiab lwm yam. Tsis muaj leej twg xav tsis thoob thaum peb tawm tswv yim tias qhov zoo ntawm txhua yam tseem ceeb, los ntawm hauv qab mus rau sab saum toj, txhua lub Cheebtsam yuav tsum. tag nrho yog cov khoom zoo tshaj plaws kom cov khoom kawg yuav dhau mus.
Rau cov motors, qhov tseeb qhov tseeb thiab concentricity ntawm lub rotor, stator thiab kawg lub kaus mom yog qhov tseem ceeb tshwj xeeb, ua kom txoj kev flux hla ntawm stator thiab rotor cov hniav thaum txo qis kev tsis txaus siab.Rau qhov no, qhov sib txawv ntawm huab cua lossis qhov sib txawv ntawm lub rotor thiab stator yuav tsum tsawg.Qhov me me ntawm qhov sib txawv ntawm huab cua, qhov me me ntawm cov khoom siv machining qhov chaw yuam kev.Qhov no suab yooj yim to taub, tab sis yog hais tias ob qho tib si los yog ob qho tib si tsis zoo concentric, ua rau cov huab cua tsis sib xws yuav ua rau kev ua haujlwm tsis zoo.Hauv qhov phem tshaj plaws, yog tias muaj kev sib cuag tshwm sim, lub cev muaj zog yuav tsis muaj txiaj ntsig.
Rotor inertia cuam tshuam rau tag nrho kev ua haujlwm ntawm lub cev muaj zog stepper. Tsawg inertia rotors tuaj yeem teb sai dua thiab muab cov neeg siv nrog kev nrawm dua thiab siab dua dynamic torque. Tsim nyog kawg cap tsim kom muaj qhov siab tshaj plaws sab hauv ntim tso rau hauv lub rotor loj.Cov kaus mom kawg yog lub luag haujlwm rau kev sib raug zoo ntawm rotor.Misalignment tuaj yeem ua rau muaj kev cuam tshuam loj rau qhov zoo ntawm cov khoom kawg, thiab rotor misalignment tuaj yeem ua rau huab cua tsis sib xws thiab ua rau kev ua haujlwm tsis zoo.
Qhov tsis sib haum xeeb concentricity no yog them rau los ntawm kev nce qhov loj ntawm cov pa sib txawv ntawm lub rotor thiab stator, txo qhov muaj feem ntawm lawv cov kev sib cuag.Qhov no tsuas yog siv tau rau kev tshem tawm qhov yuam kev.Txoj kev no ua rau muaj kev cuam tshuam loj rau kev ua haujlwm ntawm stepper motors, thiab qhov ntau dua qhov sib txawv ntawm qhov chaw, qhov kev ua haujlwm tsis sib haum yuav ntau dua.Txawm tias cov kev hloov me me tuaj yeem muaj qhov cuam tshuam loj rau inertia, tsis kam, inductance, dynamic torque tso zis thiab resonance (tsis xav tau kev co).Kev tsim ntawm lub rotor yog qhov tseem ceeb rau kev ua kom zoo tshaj plaws ntawm lub cev muaj zog, lub rotor yuav tsum nthuav tawm cov hlau nplaum txaus thaum tseem tshuav li lub teeb kom txo tau qhov inertia ntawm lub rotor.
Lub stator tuaj yeem hloov kho raws li lub hom phiaj kawg ntawm kev tsim: siab raug, smoothness los yog siab torque tso zis, thiab tus tsim ntawm tus ncej txiav txim siab npaum li cas winding khoom yuav haum ntawm stator ncej.Tsis tas li ntawd, tus naj npawb ntawm cov ncej feem ntau yog 8, 12 lossis 16 sib cuam tshuam nrog qhov tseeb thiab lub zog tso tawm ntawm lub cev muaj zog.Cov ncej yuav tsum muaj zog txaus los tiv thaiv rov qab torque loads thiab axial rog yam tsis muaj deformation lossis degradation dhau sijhawm.Ib yam li ntawd, bearings yuav tsum phim qhov kev ua tau zoo thiab lub neej expectancy ntawm cov khoom kawg.Raws li cov khoom siv uas txiav txim siab lub neej ntawm lub cev muaj zog, bearings feem ntau ntsib qhov hnav tshaj plaws.
Lwm yam tseem ceeb xws li lub kaus mom kawg, uas tuav cov bearings nyob rau hauv qhov chaw thiab xyuas kom meej kev sib raug zoo ntawm stator thiab rotor.Cov bearings lawv tus kheej kuj yuav tsum tau ua kom zoo tshaj plaws los tswj thiab ua kom lub neej ntev ntawm lub tshuab stepper.Txhua tus ncej yog qhov tseem ceeb ntawm electromagnet, uas yuav tsum muaj qhov sib npaug ntawm txhua tus ncej siv cov xaim qib siab tshaj plaws.Variations nyob rau hauv txoj kab uas hla yuav ua rau ib tug ncej winding sib xws teeb meem, uas yuav ua rau cov tsis zoo torque specification, muaj zog resonance los yog vibration, thiab kev daws teeb meem tsis zoo nyob rau hauv cov khoom kawg.
nyob rau hauv xaus
Yuav ua li cas xaiv cov khoom lag luam zoo thiab yeej-yeej yuav tsum muaj cov txheej txheem kev soj ntsuam zoo thiab cov cuab yeej tshawb fawb tau zoo los txhim kho cov khoom lag luam kev tswj hwm kev muaj peev xwm thiab txhawb kev txhim kho kev lag luam lub cev muaj zog.Txhawm rau kom ntseeg tau tias cov motors zoo, txhua lub cev muaj zog raug kuaj ua ntej xa khoom kom tau raws li qhov yuav tsum tau muaj hluav taws xob (kuj, inductance, to tam sim no), torque specifications (tuav thiab nres torque), mechanical specifications (pem hauv ntej qag extension thiab lub cev ntev) thiab lwm yam tshwj xeeb nta.
