Cais ruam lub cev muaj zog tus neeg tsav tsheb lub ntsiab cai
Ruam lub cev muaj zog, tseem muaj lub cev muaj zog, yog cov khoom siv kho mob zoo, thiab muaj kev ntseeg siab, cov cuab yeej siv kho mob, cov khoom siv hlau, thiab ntau yam khoom siv hluav taws xob. Nws tsav tsheb yog dab tsi?
1. Tus ua haujlwm ntawm lub cev muaj zog stepper:
Tus txheej txheem ua hauj lwm ntawm state state lub cev muaj zog yog kom pom kev hloov pauv ntawm cov hluav taws xob, yog li kom paub cov meej txheej txheem kev tswj hwm.
2. Tus tsav tsheb ntawm lub cev muaj zog stepper:
Lub hauv paus ntsiab lus ntawm tus tsav ntawm lub cev muaj zog stepper yog hloov cov paib mem tes, thiab tom qab ntawd cov teeb liab tam sim no mus rau lub cev muaj zog tam sim no, lub dav hlau loj tuaj yeem paub qhov kev sib hloov.
3. Tsav daim duab schematic ntawm stepper tsav:
Stepper Lub Cev Muaj Zog Tsav Schematic feem ntau muaj cov teeb tsa kev sib hloov, cov mem tes uas muaj teeb meem tam sim no, thiab tus neeg tsav tsheb thaum kawg nkag mus rau lub teeb liab stepper.
Tus qauv ua hauj lwm ntawm stateper lub cev muaj zog tsav
Qaum lub cev muaj zog muaj ntau cov kev siv hauv cov txheej txheem tswj. Nws tuaj yeem hloov mem tes cim rau hauv Angular qhov chaw tsis zoo, thiab tuaj yeem siv raws li electromagnet pops, electromagnetic stands, lossis angular tsheb ciav hlau.
Qee zaum tshem tawm qee cov cuab yeej qub ntawm lub cev muaj zog stepper (lub cev muaj zog no feem ntau tsis raug puas tsuaj) yuav tsum tau siv rau lwm lub hom phiaj, feem ntau yuav tsum tau tsim lawv tus kheej tsav tsheb. Daim ntawv no nthuav qhia lub cev muaj zog stepper tshem tawm los ntawm cov tshuab luam ntawv Japanese qub thiab tsim ntawm tus neeg tsav tsheb. Daim ntawv no ua ntej nthuav qhia tus ua haujlwm ntawm lub cev muaj zog stepper, thiab tom qab ntawd qhia nws cov software driver thiab kho vajtse.
1. Stepper Lub Ntsiab Lus Lub Ntsiab Lus
Lub cev muaj zog stepper yog plaub -}} phase stepper lub cev muaj zog, powered los ntawm Unipolar DC Lub Cev Khoom Siv DC. Ntev npaum li lub windings ntawm txhua theem ntawm lub cev muaj zog stepper kom energized raws li lub sijhawm tsim nyog, lub zog stepper tuaj yeem tig mus tig kauj ruam los ntawm kauj ruam. Daim duab 1 yog cov qauv schematic ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm no plaub {{}}}} theem reactive stepper tsav.

2. Raws li ntawm At89c 51 stepper lub cev muaj zog tsav tsheb system system kab ke
AT89C51 tswj cov pulses los ntawm P1 Chaw nres nkoj P1.4 ~ P1.7 tawm los ntawm 9014 kev tswj hwm ntawm lub zog ntawm 9014 mus rau 9014 kev ua kom nrov dua, tsav tsheb kauj ruam ntawm cov winder. Ua lub cev muaj zog stepper nrog cov cim mem tes sib txawv rau pem hauv ntej, thim rov qab, ua kom nrawm, deceyerate thiab nres thiab lwm yam kev nqis tes ua. L1 nyob rau hauv daim duab rau lub stepper tsav theem winding. AT89C51 Xaiv Zaus 22MHz Crystal, lub hom phiaj xaiv lub tshuab ua kom tsawg dua ntawm at89c2051 ntawm cov mem tes teeb liab ntawm cov host lub computer nyob rau hauv txoj kev 2.
RL1 ~ RL4 rau kev siv cua tsis muaj zog, yog ib lub luag haujlwm sab nraud los ntawm kev txhawb nqa lub zog
Hauv qhov 50ω sab nraud tsis kam nyob rau hauv parallel nrog lub capsecor tuaj yeem txhim kho cov mem tes tsav tam sim no winding, txhim kho lub siab- zaus ua tau zoo ntawm lub tsheb kauj vab. Lub 200ω resistor txuas rau hauv cov koob nrog kev txuas ntxiv ntawm cov phiaj xwm tsis tu ncua thiab lub luag haujlwm tam sim no, tseem ua rau muaj kev sib tw tam sim no, uas tseem ua tau zoo dua qub {5} {zaus kev ua tau zoo.
3. Software tsim
Tus tsav tsheb raws li cov sib xyaw sib txawv ntawm cov kais dej hloov mus, ky muaj peb hom ua haujlwm xaiv los ntawm:
Hom 1 yog qhov cuam tshuam hom:P3.5 (Int1) Puas yog cov tswv yim tseem ceeb, thiab P3.7 yog cov lus qhia rau pem hauv ntej thiab thim rov qab. Lub computer sab sauv (PC lossis microcontroller) thiab tus tsav tsheb txuas nrog 2 kab nkaus xwb.
Hom 2 yog hom kev sib txuas lus serial:Tus tswv tsev computer (PC lossis microcontroller) xa cov tswj hwm tus neeg tsav tsheb, thiab tus tsav tsheb ua tiav cov txheej txheem kev tswj hwm raws li kev tswj hwm.
Hom 3 yog DIP hloov Met tswj hom:Lub cev muaj zog stepping tau tswj hwm los ntawm kev sib xyaw sib txawv ntawm K1 txog K5.
Thaum lub zog yog nyob rau lossis rov pib dua KR yog nias, AT89C 51 kuaj cov xwm txheej ntawm DIP hloov pauv raws li cov sib txuas ua ke ntawm KX thiab KY. Qhov kev zov me nyuam khiav thaiv kev thaiv thiab cov haujlwm rau hom 1 yog muab hauv qab no.
Nyob rau hauv kev npaj ntawm qhov kev pab cuam, kev tshwj xeeb yog yuav tsum tau them rau kev tuav ntawm lub caij theem nrab thaum lub sijhawm sib tham. Txhawm rau ua kom lub cev muaj zog stepper nyob rau hauv kev sib tw tuaj yeem hloov tau, tsis yog tsim cov kauj ruam tsis yog, yuav tsum teeb tsa hauv txhua kauj ruam ntawm tus chij. Ntawm lawv, txhua qhov ntawm 20H chav tsev yog lub kauj ruam tsav rau pem hauv ntej chij; Txhua tus ntawm 21h chav tsev yog qhov rov qab chij me ntsis. Hauv kev sib hloov rau pem hauv ntej, tsis yog rau pem hauv ntej chij me me tus nqi, tab sis kuj nyob rau tib lub sijhawm rau cov chij ntawm tus nqi me ntsis; hauv kev thim rov qab ntawm tib yam. Nyob rau hauv txoj kev no, thaum lub cev muaj zog stepper hloov, nws tuaj yeem yog tus kawg txoj hauj lwm uas pib kev hloov pauv hloov pauv los ua cov kauj ruam tsis yog.
