Txawm hais tias tus neeg xav tau cov hlau nplaum dab tsi, nws tuaj yeem ua tau yooj yim hauv tsev. Thaum zoo li no nyob ntawm tes, nrog nws cov kev pab koj tuaj yeem tsis tsuas yog muaj kev lom zem, khaws ntau yam me me ntawm cov hlau los ntawm lub rooj, tab sis kuj nrhiav kev siv tau zoo rau nws, piv txwv li, nrhiav ib rab koob poob rau ntawm cov ntaub pua plag. Los ntawm kab lus no koj yuav kawm paub tias nws yooj yim npaum li cas los ua ib lub tshuab hluav taws xob nrog koj tus kheej tes hauv tsev.
me ntsis ntawm physics
Raws li peb nco ntsoov (lossis tsis nco qab) los ntawm cov lus qhia physics, txhawm rau hloov hluav taws xob mus rau hauv qhov chaw sib nqus, koj yuav tsum tsim qhov induction. Lub inductance yog tsim los ntawm ib tug dog dig kauj, nyob rau hauv uas lub teb no tshwm sim thiab kis mus rau ib tug hlau core, nyob ib ncig ntawm lub coil yog mob.
Yog li, nyob ntawm qhov polarity, ib qho kawg ntawm cov tub ntxhais yuav tawm ib daim teb nrog lub cim rho tawm, thiab qhov rov qab kawg nrog lub cim ntxiv. Tab sis rau kev pomLub peev xwm sib nqus ntawm polarity tsis muaj kev cuam tshuam. Yog li, thaum lub physics dhau lawm, koj tuaj yeem txiav txim siab los tsim cov electromagnet yooj yim nrog koj tus kheej tes.
Khoom siv los ua cov hlau nplaum yooj yim
Ua ntej tshaj plaws, peb xav tau ib qho inductor nrog tooj liab hlau qhov txhab nyob ib ncig ntawm cov tub ntxhais. Nws tuaj yeem yog ib qho transformer zoo tib yam los ntawm txhua lub hwj huam mov. Ib qho cuab yeej zoo tshaj plaws rau kev tsim cov hlau nplaum yog winding nyob ib ncig ntawm lub nraub qaum ntawm lub kinescopes ntawm cov saib qub lossis TV. Cov strands ntawm cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob muaj kev tiv thaiv los ntawm kev rwb thaiv tsev, uas muaj cov txheej txheem yuav luag tsis pom ntawm cov kua roj vanish tshwj xeeb uas tiv thaiv kev hla ntawm hluav taws xob tam sim no, uas yog qhov peb xav tau. Ntxiv nrog rau cov khoom qhia, txhawm rau tsim lub tshuab hluav taws xob nrog koj tus kheej tes, koj kuj yuav tsum tau npaj:
- Lub roj teeb ib txwm rau ib thiab ib nrab Volts.
- daim kab xev los yog daim kab xev.
- riam ntse.
- Npaj weave.
txheej txheem ntawm kev ua cov hlau nplaum yooj yim
Pib los ntawm kev tshem cov xov hlau los ntawm lub tshuab hloov pauv. Raws li txoj cai, nws nruab nrab yog nyob rau hauv lub steel ncej. Nws yog ib qho ua tau, tshem tawm cov rwb thaiv tsev saum npoo ntawm lub kauj, kom yooj yim unwind cov hlau, rub nws ntawm cov thav ntawv thiab cov kauj. Txij li thaum peb tsis xav tau ntau cov hlau, cov qauv no yog qhov zoo tshaj plaws ntawm no. Thaum peb tso cov hlau txaus lawm, peb ua cov hauv qab no:
- Peb cua cov hlau tshem tawm ntawm lub tshuab hloov pauv ib puag ncigib tug ntsia hlau uas yuav ua ib tug hlau core rau peb electromagnet. Nws yog ib qho tsim nyog yuav tau ua kom tig ntau li ntau tau, nias lawv nruj nreem rau ib leeg. Tsis txhob hnov qab tawm qhov ntev ntawm cov xaim ntawm qhov pib tig, dhau los ntawm peb lub tshuab hluav taws xob yuav raug xa mus rau ib tus ncej ntawm lub roj teeb.
- Thaum peb mus txog qhov kawg ntawm tus ntsia thawv, peb kuj tso ib tug ntev conductor rau lub hwj chim. Txiav tawm cov hlau ntau dhau nrog rab riam. Txhawm rau tiv thaiv cov kab mob kis los ntawm peb los ntawm kev tsis sib haum, koj tuaj yeem qhwv nws nrog daim kab xev lossis daim kab xev hluav taws xob.
- Peb ntxuav ob qhov kawg ntawm cov hlau los ntawm cov ntsia hlau qhov txhab los ntawm cov kua roj vanish nrog rab riam.
- Peb lean ib kawg ntawm cov stripped conductor mus rau ntxiv ntawm lub roj teeb thiab tuav nws nrog daim kab xev los yog daim kab xev kom qhov kev sib cuag tau zoo.
- Lwm kawg yog txuas rau tus rho tawm tib yam.
Lub tshuab hluav taws xob npaj mus. Los ntawm tawg cov ntawv hlau los yog cov nyees khawm ntawm lub rooj, koj tuaj yeem tshawb xyuas nws qhov kev ua tau zoo.
Yuav ua li cas thiaj ua tau cov hlau nplaum muaj zog?
Yuav ua li cas thiaj ua tau lub tshuab hluav taws xob nrog cov khoom sib nqus muaj zog dua nrog koj tus kheej txhais tes? Lub zog ntawm cov hlau nplaum yog cuam tshuam los ntawm ntau yam, thiab qhov tseem ceeb tshaj plaws ntawm lawv yog lub zog hluav taws xob ntawm lub roj teeb uas peb siv. Piv txwv li, tau ua ib qho electromagnet los ntawm ib lub roj teeb square ntawm 4.5 volts, peb yuav triple lub zog ntawm nws cov khoom sib nqus. Lub kaus mom 9-volt yuav muab cov txiaj ntsig zoo dua.
Tab sis tsis txhob hnov qab tias qhov hluav taws xob muaj zog dua, ntau duaKev hloov pauv yuav tsum tau ua, txij li qhov kev tawm tsam nrog tus lej me me ntawm cov lem yuav muaj zog heev, uas yuav ua rau muaj zog cua sov ntawm cov conductors. Yog hais tias lawv yog rhuab heev, lub insulating kua roj vanish yuav pib yaj, lub lem yuav pib luv luv ntawm ib leeg los yog nyob rau hauv lub steel core. Ob leeg yuav sai lossis tom qab ntawd ua rau luv luv.
Tsis tas li ntawd, lub zog ntawm cov hlau nplaum nyob ntawm tus naj npawb ntawm cov lem nyob ib ncig ntawm lub hauv paus ntawm cov hlau nplaum. Qhov ntau muaj, qhov muaj zog qhov induction teb yuav muaj zog, thiab cov hlau nplaum yuav muaj zog dua.
Ua kom muaj zog hlau nplaum ntau dua
Cia peb sim ua 12 volt electromagnet nrog peb tus kheej tes. Nws yuav siv tau los ntawm 12-volt AC adapter lossis 12-volt tsheb roj teeb. Yuav kom ua tau nws, peb xav tau ntau npaum li cas ntawm tooj liab conductor, thiab yog li ntawd peb yuav tsum pib tshem tawm lub internal coil nrog tooj liab hlau los ntawm lub npaj transformer. Bulgarian yog txoj hauv kev zoo tshaj plaws los rho tawm nws.
Yuav ua li cas peb yuav tsum ua:
- Steel horseshoe los ntawm lub xauv loj, uas yuav ua haujlwm raws li peb lub hauv paus. Nyob rau hauv cov ntaub ntawv no, nws yuav ua tau rau magnetize tej daim hlau nrog ob hnub, uas yuav ntxiv lifting peev xwm ntawm cov hlau nplaum.
- Cov coil nrog varnished tooj liab hlau.
- Insulating daim kab xev.
- Knife.
- Tsis tsim nyog 12 volt fais fab mov lossis tsheb roj teeb.
txheej txheem ua kom muaj zog 12-volt hlau nplaum
Tau kawg, lwm yam hlau hlau loj tuaj yeem siv los ua cov tub ntxhais. Tab sis tus nees nees yog los ntawm lub tsev qub qubhaum zoo kawg nkaus. Nws khoov yuav ua haujlwm zoo li tus kov yog tias peb pib nqa cov khoom uas muaj qhov hnyav hnyav. Yog li, nyob rau hauv cov ntaub ntawv no, txheej txheem ntawm kev ua ib tug electromagnet nrog koj tus kheej txhais tes yog raws li nram no:
- Peb cua cov hlau los ntawm lub tshuab hloov pauv ib ncig ntawm ib tus nees nees. Peb muab cov coils kom nruj li sai tau. Lub horseshoe khoov yuav nkag mus rau hauv txoj kev me ntsis, tab sis tsis ua li cas. Thaum qhov ntev ntawm sab ntawm horseshoe xaus, peb nteg lub lem nyob rau hauv lub opposite kev taw qhia, nyob rau sab saum toj ntawm thawj kab ntawm lem. Peb ua tag nrho ntawm 500 lem.
- Thaum lub winding ntawm ib nrab ntawm cov horseshoe npaj txhij, peb qhwv nws nrog ib txheej ntawm daim kab xev hluav taws xob. Thawj qhov kawg ntawm cov hlau npaj rau kev pub noj los ntawm qhov chaw tam sim no yog coj mus rau sab saum toj ntawm lub neej yav tom ntej. Peb qhwv peb lub kauj rau ntawm ib lub horseshoe nrog lwm txheej ntawm hluav taws xob daim kab xev. Peb cua qhov kawg ntawm tus neeg xyuas pib mus rau qhov khoov ntawm tus kov thiab ua rau lwm lub kauj ntawm sab nraud.
- Khawb cov hlau ntawm sab nraud ntawm tus nees nees. Peb ua txhua yam nyob rau hauv tib txoj kev raws li nyob rau hauv rooj plaub ntawm thawj sab. Thaum 500 tig, peb kuj coj tawm qhov kawg ntawm cov hlau rau lub zog los ntawm lub zog. Rau cov neeg tsis nkag siab, cov txheej txheem qhia tau zoo hauv daim video no.
theem kawg ntawm kev ua ib lub tshuab hluav taws xob nrog koj tus kheej txhais tes yog pub rau lub zog. Yog tias qhov no yog lub roj teeb, peb tsim qhov kawg ntawm cov stripped conductors ntawm peb cov electromagnet nrog kev pab los ntawm cov xov hlau ntxiv uas peb txuas rau lub roj teeb terminals. Yog tias qhov no yog lub zog hluav taws xob, txiav tawm lub ntsaws uas mus rau cov neeg siv khoom, rub cov xov hlau thiab txuas rau txhua tushlau los ntawm electromagnet. Cais nrog daim kab xev. Peb qhib lub hwj huam mov rau lub qhov (socket). Nrog koj zoo siab. Koj tau ua lub zog 12 volt electromagnet nrog koj tus kheej tes, uas tuaj yeem nqa tau ntau tshaj 5 kg.
