Stepper Tsav Angular Position Detection
Rau kev ua haujlwm ntawm kev ua haujlwm, feem ntau yog siv ob txoj kev nrhiav pom: ib txoj hauv kev yog siv cov qauv ua kom rov qab, qhov sib thooj ntawm tus qauv photocopy. kev cia siab, kev daws teeb meem siab, kev siab tshaj, me me, lub cev nyhav thiab zoo li ntawd.
Thaum siv nws, ua cov cai thiab qhov chaw ua hauj lwm axis coaxial kev twb kev txuas, kev tso zis tso rau lub kaum ntse ntse coding, tso tawm cov lus tso tawm rau microcontroller, tom qab lo seev suab tau txais lub kaum sab xis, tsis muaj ntxiv Circuit Court, xws li A / D conversion, zoom lim. Lub zog tswj qhov kev siv zog ntawm lub tshuab hluav taws xob uas siv cov duab thaij duab tau pom nyob hauv daim duab 1, thiab tso tawm ntawm daim duab ntawm tus qauv photodetric hauv daim duab 1 yog muab rov qab los rau cov khoom siv hluav taws xob.Qhov tswj kev tswj kev kho kom haum rau lub kaum sab xis ntawm lub kauj ruam khiav raws li cov lus tawm tswv yim .
Daim duab 1 siv qhov kev yees duab thaij duab hluav taws xob tswj qhov system
Zuag qhia tag nrho
Lub kauj ruam tsav yog tsav los ntawm lub tshuab hluav taws xob, uas yog tus tsav tsheb tsav uas ua rau lub suab paj nruag khiav los ntawm txoj kev tswj kom tsav tau lub cav ntaiv kev tsav tsheb.Qhov kev khiav ntawm lub cav ntais ntawv yog sib luag rau cov zaus ntawm cov mem tes cov teeb meem. pulse teeb liab ntau zaus kom yog lub cav, tswj cov naj npawb ntawm cov hlab ntsha mus rau qhov tseeb .
Stepper motor tsav tswj muaj peb yam nram qab no:
1.Stepping tswj
2.Stepper tsav;
3. Lub cev muaj zog.
Lub kauj vab stepper yog siv los ntawm cov microcontroller, thaum stepper drives ua kom nrov ntawm lub tshuab pulses los ntawm microcontroller tsav lub cavper tsav.Qhov system ntawm ib leeg-nti tswj stepper motor system daim duab thaiv hauv daim duab 2. Tsis txhob siv DC
los yog AC cov tsheb nqus hlau tsav tsheb, yuav tsum tau siv lub voj voog khiav ntawm kev tsav tsheb, los yog nrog ib qho khoom sib txuas ntawm lub Circuit Court.
Daim duab 2 nris daim duab ntawm cov hlua cav
Raws li kev tsav tsheb pib khiav tam sim no, tus tsav hluav taws xob muab faib rau hauv qhov tsav ntawm qhov tsav tsheb thiab kev tsav tsheb sib tsoo ua ke. Txhuas tsav tsheb kom pom tseeb tias lub cev muaj zog qis hauv ib qho kev taw qhia, tsim kom muaj cov kauj ruam khiav qis dua; , tuaj yeem ua rau lub zog qeeb tam sim no zoo / tsis pom zoo, kom ruaj khov thiab hybrid stepper tsav.
