2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:28

Cia peb ua lub tshuab hluav taws xob uas tig siv cov hlau nplaum neodymium thiab xaim. Qhov no qhia pom tias hluav taws xob tam sim no hloov pauv mus li cas.

Peb tab tom tsim lub cav DC uas tsis txhuam txhuam. Nws yuav tsis mus los yeej ib yam efficiency los yog tsim khoom plig, tab sis peb xav ib tug yooj yim piv txwv ua rau nws yooj yim mus saib dab tsi yog yuav mus.

Cov ntaub ntawv xav tau:

-(2) neodymium hlau nplaum

-Rotor (peb siv cov kabmob 608ZZ)

-Magnet hlau

-Steel ntsia liaj qhov rooj

-Breadboard

-Electronics - Reed hloov, transistor, flyback diode, 20ohm resistor, LED, 6V DC fais fab mov. Peb siv 4AA roj teeb hauv pob roj teeb

Kauj ruam 1: DIY Rotor

Ib feem ntawm lub cav hluav taws xob hu ua rotor. Feem ntau cov tshuab tsis txhuam muaj cov hlau nplaum ruaj khov ntawm lub rotor.

Peb lub rotor tig ua tsaug rau 608ZZ cov kabmob daig ntawm tus xaum. Cov kabmob no feem ntau siv hauv yam xws li lub log skateboard thiab fidget spinners.

Peb daig ob 1/4 "x 1/4" x 1/8 "B442 neodymium hlau nplaum nyob rau sab ntug ntawm cov kabmob, 180 degrees sib nrug los ntawm ib leeg. Ob leeg tau taw qhia nrog lawv cov ncej sab qaum teb tig tawm. Qhov no txawv dua li feem ntau BLDC motors uas tau alternating tug txojkev tawm. Qhov no simplification ua peb siv hluav taws xob circuitry ib tug me ntsis yooj yim.

Kauj ruam 2: Tau txav mus

Yuav ua li cas peb thiaj tau txais qhov no tig? Peb tsuas tuaj yeem nplawm nws nrog peb tus ntiv tes, tab sis peb tab tom nrhiav rau lub zog sib nqus. Nqa lwm magnet nyob ze ib tug ntawm cov rotor hlau nplaum, nrog nws tus sab qaum teb ncej txojkev rau sab qaum teb ncej ntawm lub rotor hlau nplaum. Qhov no yuav ua rau cov hlau nplaum tawm tsam, lossis thawb, teeb tsa lub rotor tig.

Yog hais tias peb thawb rau cov hlau nplaum tsis txaus rau saws tus rotor tog nyob ib ncig ntawm, peb yuav ua li cas nws rov mus rau tom ntej no cov hlau nplaum. Yog hais tias peb ceev txaus, peb yuav kom muab cov hlau nplaum nyob ze thiab noj tam sim ntawd, spinning lub rotor tsis tu ncua.

Qhov no yog qhov twg lub electronics tuaj nyob rau hauv. Peb xav los ua ib tug electromagnet uas lem tawm ib rau, thawb lub rotor hlau nplaum.

Kauj Ruam 3: Electromagnet

Ib qho hluav taws xob uas yooj yim muaj cov kauj ntawm cov hlau nplaum hlau qhwv ib ncig ntawm cov hlau hlau. Peb siv 24 gauge, ib strand tooj liab hlau nplaum hlau nrog ib tug nyias, enamel rwb thaiv tsev. Cov ntsia hlau tau dhau los ua cov hlau hlau.

Thaum peb siv qhov hluav taws xob rau nws, nws dhau los ua cov hlau nplaum. Nrog lub tshuab hluav taws xob nyob rau sab xis, nws yuav tsum thawb lub rotor hlau nplaum tam sim ntawd. Tam sim no txhua yam peb yuav tsum ua yog qhib nws thiab tawm ntawm lub sijhawm raug.

Peb xav tig lub electromagnet rau xwb tom qab ib yam ntawm cov rotor magnet kis tus ntsia liaj qhov rooj, thawb nws tam sim ntawd. Tom qab taug kev me ntsis, hais 30 degrees lossis ntau dua, nws yuav tsum tig rov qab. Peb tuaj yeem ua qhov no hloov pauv hluav taws xob li cas?

Kauj Ruam 4: Sib Nqus Sensor

Peb tau xaiv tus pas nrig los qhia peb thaum cov hlau nplaum nyob hauv txoj haujlwm raug. Ib tug reed mus yog ib tug iav-encased sensor, qhov twg ob ferromagnetic ua yog yuav luag kov ub kov no ib leeg. Ua ntawv thov sib nqus rau lub ntsuas cua nrog tsuas yog siv lub zog sib nqus kom raug thiab kev coj ua, thiab nws ua rau ob qho no coj mus kov ib leeg, ua hluav taws xob tiv tauj thiab ua tiav lub Circuit Court.

Nrog tus kav tauj los hloov positioned raws li qhia, nws yuav ua rau hu xwb thaum lub sij hawm qhov tseeb feem ntawm lub rotor txoj kev tig.

Kauj Ruam 5: Kawg Circuit - Txhim Kho

Thaum qhov yooj yim reed hloov teeb tsa ua haujlwm luv luv, peb tau nrawm mus rau hauv cov teeb meem. Peb tau khiav ntau qhov tam sim no los ntawm qhov hloov pauv reed thiab nws txuas ob qhov kev sib cuag ua ke. Qhov no yog vim peb qhov tseem ceeb luv lub roj teeb.

Txhawm rau kho qhov teeb meem no, peb ntxiv cov transistor. Hloov chaw kom muaj tag nrho cov hluav taws xob hluav taws xob tam sim no dhau los ntawm qhov hloov pauv, peb tau siv lub reed hloov mus rau lub transistor qhib thiab tawm, yog li tam sim no mus los ntawm transistor xwb. Lub transistor yog qhov pib-rau hloov uas tuaj yeem ua haujlwm me ntsis ntxiv.

Kev teeb tsa zaum kawg kuj suav nrog lub diode los tiv thaiv rov qab los ntawm lub tshuab hluav taws xob. Qhov no yog hu ua ib tug "Flyback Diode", uas tiv thaiv qhov tam sim no los ntawm kib cov transistor thaum nws puv tawm.

Kauj Ruam 6: Saib Nws Ua Haujlwm

Nrog lub tshuab hluav taws xob hloov pauv tsuas yog dhau los ntawm ib feem me me ntawm kev sib hloov, lub rotor tig tsis tu ncua! Txheeb nws tawm hauv video.

Peb ntxiv ib qho LED uas teeb thaum lub electromagnet yog tshuab txais kev pab pom tau dab tsi yog yuav mus.

Hauv daim duab, koj tuaj yeem pom qhov ntsuas hluav taws xob hla lub kauj, tig thiab tawm!
