2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31

Tam sim no koj tuaj yeem muaj lub zog tswj hwm tas li ntawm koj lub ntsis ntiv tes nrog Tsis muaj roj teeb los hloov lossis rov ua dua! Cov Lus Qhia no qhia koj yuav hloov kho lub teeb nyem lub teeb nyem rau hauv lub zog txhais tau li cas uas tuaj yeem hloov roj teeb rau txhua txoj haujlwm xav tau nrawm 5 volt ncaj qha-tam sim no (5V DC) lub zog.

Yog tias koj tau suav nrog cov lej digital, analog chips, lossis microcontroller rau hauv txoj haujlwm muaj txoj hauv kev zoo koj yuav tsum tau nrhiav txoj hauv kev los muab 5V DC rau koj qhov Circuit. Muaj ob peb qhov chaw tseem ceeb ntawm 5V, yog li koj tuaj yeem siv phab ntsa wart los hloov AC zog (uas pom tseeb txwv qhov twg koj tuaj yeem nqa koj lub cuab yeej tshiab) lossis koj tuaj yeem siv sijhawm ntxiv los tsim kev tswj hwm Circuit kom tau ntau lub roj teeb 1.5V rau qhov xav tau. qhov hluav taws xob Cov kev daws teeb meem no xav tau rau qee qhov kev siv hluav taws xob, tab sis rau cov cuab yeej me dua, puas yog nws tsis zoo kom muaj cov khoom siv tas li yog li koj tuaj yeem ncaj qha mus ua haujlwm ntawm lwm yam ntawm txoj haujlwm? Los ntawm kev ntxiv ob peb yam khoom siv hluav taws xob mus rau qhov dav dav siv lub teeb nyem, koj tuaj yeem siv lub zog me me rau lub sijhawm luv luv yam tsis siv lub qhov hluav taws xob lossis roj teeb. Kev txhim kho dynamo yog qhov zoo rau lub rooj ua haujlwm lossis qhia tawm cov haujlwm tshiab tsuas yog nyob txhua qhov chaw. Cov lus qhia no yuav qhia txog yuav ua li cas sib sau ua ke thiab teeb tsa theem-nce DC-DC hloov pauv uas hloov pauv qhov sib txawv qis ntawm qhov tseem ceeb dynamo lub tshuab hluav taws xob rau hauv 5V tas li. Cov theem hluav taws xob them nqi hluav taws xob loj uas muab lub zog cia thiab qee lub zog txawm tias lub zog tsis tig. Los ntawm ua raws cov kauj ruam hauv Cov Lus Qhia no, koj tuaj yeem ua tiav txhua qhov no yam tsis tau tsim khoom tshwj xeeb hauv pawg thawj coj saib lossis siv cov khoom nyuaj rau-rau-solder nto mount Cheebtsam. Txhawm rau kom tau txais cov khoom siv hluav taws xob sab hauv cov ntaub ntawv tseem ceeb yuav tsum muaj qee qhov hluav taws xob hauv origami, tab sis tom qab kwv yees li ib teev ntawm tinkering koj yuav muaj cov cuab yeej zoo uas tuaj yeem siv txog li 50 milliamps ntawm tam sim no ntawm qhov tsis tu ncua 5V DC thaum winding thiab milliwatts ntawm lub zog rau feeb tom qab. !

Kauj Ruam 1: Nws Ua Haujlwm Li Cas

Lub tshuab hluav taws xob tam sim no ntws mus rau hauv lub cev muaj zog tsim cov hlau nplaum hauv cov coils txuas rau lub taub hau, uas tig los ntawm qhov muaj cov hlau nplaum los ntawm cov hlau nplaum ruaj khov. Thaum lub cav khiav rov qab - lub zog tau thov los ntawm kev tig lub ncej - qhov hluav taws xob tau ua rau hauv lub kauj. Faraday txoj cai hais tias qhov hluav taws xob no yog sib piv rau tus nqi sib nqus hloov pauv hauv cov kauj. Yog li tus ncej tau tig nrawm dua, qhov ntau dua qhov hluav taws xob. Qhov kev sib piv Cov zog ntawm cov zog tau siv nyob rau hauv qhov tseem ceeb kom tau txais lub tshuab hluav taws xob tig nrawm li sai tau. Thaum koj crank tus kov, nws teeb tsa peb lub zog sib zog ua zog. Ib nrab ntawm txhua qhov sib xyaw iav muaj lub vojvoog me me thiab lwm qhov ib nrab muaj lub vojvoog loj. Thaum lub vojvoog me me tig, cov hniav ntawm ntug ntawm lub vojvoog loj dua hloov chaw ntawm qhov feem cuam nrawm dua. Los ntawm cascading cov khoom sib xyaw no, cov cranking tus nqi tuaj yeem sib tw ob peb zaug thiab lub tshuab hluav taws xob tuaj yeem tig nrawm dua li tib neeg tuaj yeem tig nws. Qhov xav tau hloov pauv hloov pauv thiab khaws cov peev txheej Lub zog ntawm lub zog sib piv tuaj yeem tsim ob peb volts nrog tsim nyog cranking, tab sis qhov hluav taws xob tsis siab txaus kom mus txog 5V. Qhov hluav taws xob no kuj sib txawv sai raws li tus ncej kev sib hloov. Txhawm rau kom tau txais qhov ruaj khov 5V, yuav tsum tau hloov pauv qib. Cov kev sib txuas tshwj xeeb tau xaiv - MAX756 - tuaj yeem hloov qhov hluav taws xob qis li 0.7V rau 5V thiab los ua ke 8 tus lej pob. Cov theem hluav taws xob txuas ntxiv yog ua raws daim ntawv thov hluav taws xob hauv MAX756 cov ntawv teev tseg. https://datasheets.maxim-ic.com/en/ds/MAX756-MAX757.pdf Txawm hais tias cov dynamo keychain teeb nyem tau tshaj tawm tias tsis xav tau roj teeb, lawv zoo li muaj peb lub roj teeb me me hauv. Lub tshuab hluav taws xob tau muab muag rau cov nyiaj npib no hauv cov khoom me me uas tsis zoo. Txawm li cas los xij, Kuv tsis xav tias cov roj teeb no xav tau rov ua dua, thiab lawv zoo li tso dej sai tom qab tso tawm thawj zaug. Cov Lus Qhia no hloov pauv cov nyiaj npib no nrog lub peev xwm loj uas tuaj yeem rov ua tau ntau dua thiab ua haujlwm tau zoo dua. Cov khoom tshwj xeeb tau xaiv rau kev siv tes yooj yim thaum ua qhov loj me me uas tseem tau ntsuas rau qhov hluav taws xob hauv Circuit Court. Nco tseg: MAX756 cov ntawv muaj C3 ua 150 uF capacitor. Lub 150 uF capacitors Kuv pom muaj lub cev loj dua li 100 uF sawv daws yuav thiab tsis haum rau hauv cov saw me me. Yog li kuv hloov C3 nrog 100 uF capacitor thiab nws zoo li ua haujlwm tau zoo.

Kauj Ruam 2: Qhov Chaw thiab Cov Cuab Yeej

Yog tias koj tsis ntsib ib qho kev tawm tsam thiab pom meej tias tsis ua haujlwm, nws muaj peev xwm muaj qhov luv luv nyob ntawm qhov hloov pauv hloov pauv Circuit.

Kauj ruam 16: Daim ntawv thov

Kuv siv lub tshuab dynamo los txhawb lub Luminary LM3S811 Lub Rooj Tswj Xyuas Kev Ntsuam Xyuas uas luam tawm "5V - tsis muaj roj teeb!" rau OLED zaub. Vim tias cov chips siv ntawm lub rooj tsavxwm no, nws thim qhov ncaj ncees ntawm tam sim no … txog 80 mA. Thiaj li nws tsis ua haujlwm ntev heev ntawm lub zog hluav taws xob kom txog thaum xav tau qee qhov cranking, tab sis nws ua haujlwm ntev txaus rau nyem cov ntawv sib txawv ntawm lub vijtsam. Lub tshuab fais fab dynamo yuav ua haujlwm zoo tshaj plaws nrog cov hluav taws xob uas kos ob peb mA tam sim no. Kev siv hluav taws xob tuaj yeem ua haujlwm ntev txog 10 feeb yam tsis muaj cranking, nyob ntawm lawv qhov kev ua haujlwm yam tsawg kawg nkaus.

Kuv kuj tau sim cov khoom siv dynamo nrog lub cav ua haujlwm. Thaum cranking, lub cav tau ua suab nrov nrog 50 mA ntawm tam sim no.
