Inductor ndi yophweka ngati gawo lamagetsi lingathe kupeza - ndi waya chabe. Komabe, zikuwoneka kuti koyilo ya waya imatha kuchita zinthu zosangalatsa kwambiri chifukwa cha mphamvu ya maginito ya koyilo.

M'nkhaniyi, tiphunzira zonse za inductors ndi zomwe amagwiritsidwa ntchito.

Inductor Basics

Pachithunzi chozungulira, inductor ikuwonetsedwa motere:

Kuti mumvetsetse momwe inductor angagwirire ntchito dera, chithunzichi ndichothandiza:

Zomwe mukuwona apa ndi batri, babu, waya wozungulira chitsulo (chikasu) ndi chosinthira. Koyilo ya waya ndi inductor. Ngati mwawerenga Momwe Ma Electromagnets Amagwirira Ntchito, mutha kuzindikira kuti inductor ndi maginito amagetsi.

Ngati mutachotsa inductor muderali, zomwe mungakhale nazo ndi tochi wamba. Mumatseka chosinthira ndipo bulb imayatsa. Ndi inductor mu dera monga momwe zasonyezedwera, khalidwe ndi losiyana kotheratu.

Bulu la nyali ndi chopinga (kukana kumapangitsa kutentha kuti ulusi wa babu uwole - onani Momwe Mababu Owala Amagwirira ntchito kuti mudziwe zambiri). Waya wa koyiloyo amakhala ndi kutsika kochepa kwambiri (ndi waya chabe), ndiye zomwe mungayembekezere mukayatsa switch ndikuti babu iziwala mochepera kwambiri. Zambiri zamakono ziyenera kutsata njira yochepetsera kupyola mu lupu. Chomwe chimachitika m'malo mwake ndikuti mukatseka chosinthira, bulb imayaka kwambiri kenako imayamba kuchepa. Mukatsegula chosinthira, babu imayaka kwambiri ndipo imatuluka mwachangu.

Chifukwa cha khalidwe lachilendoli ndi inductor. Koyiloyo ikayamba kuyenda, koyiloyo imafuna kupanga maginito. Pamene munda ukumanga, koyilo imalepheretsa kuyenda kwamakono. Munda ukamangidwa, magetsi amatha kuyenda bwino kudzera muwaya. Chophimbacho chikatsegulidwa, mphamvu ya maginito yozungulira koyiloyo imayendabe mu koyiloyo mpaka gawolo litagwa. Izi zimapangitsa kuti bulb ikhale yoyaka kwa nthawi yayitali ngakhale switchyo ili yotseguka. Mwa kuyankhula kwina, inductor ikhoza kusunga mphamvu mu mphamvu yake ya maginito, ndipo inductor imakonda kukana kusintha kulikonse kwa kuchuluka kwa zomwe zikuchitika panopa.

Ganizilani za Madzi…

Njira imodzi yowonera kachitidwe ka inductor ndiyo kulingalira njira yopapatiza yokhala ndi madzi akuyenda mkati mwake, ndi gudumu lamadzi lolemera lomwe zopalasa zake zikuviika mu ngalandeyo. Tangoganizani kuti madzi mumsewu sakuyenda poyamba.

Tsopano mukuyesera kuyambitsa madzi. Magudumu opalasa amatha kulepheretsa madzi kuyenda mpaka atabwera mwachangu ndi madzi. Ngati mutayesa kuyimitsa kutuluka kwa madzi mumsewu, gudumu lamadzi lozungulira lidzayesa kuti madzi asamayende mpaka kuthamanga kwake kumachepetsanso kuthamanga kwa madzi. Inductor ikuchita chimodzimodzi ndi kutuluka kwa ma electron mu waya - inductor imatsutsa kusintha kwa kayendedwe ka ma electron.

WERENGANI ZAMBIRI

Henry

Mphamvu ya inductor imayendetsedwa ndi zinthu zinayi:

Chiwerengero cha ma coils - Ma coils ochulukirapo amatanthauza kutulutsa kochulukirapo.

Zinthu zomwe ma coils amakulungidwa (pakati)

Malo ozungulira a koyilo - Malo ochulukirapo amatanthauza inductance yambiri.

Kutalika kwa koyilo - Coil yaifupi imatanthawuza zochepetsetsa (kapena zopiringizana), zomwe zikutanthauza kuti inductance yambiri.

Kuyika chitsulo pachimake cha inductor kumapereka mphamvu yochulukirapo kuposa mpweya kapena maziko aliwonse opanda maginito.

The standard unit of inductance ndi henry. Equation powerengera kuchuluka kwa henries mu inductor ndi:

H = (4 * Pi * #Kutembenuka * #Kutembenuka * Malo a coil * mu) / (Utali wa koyilo * 10,000,000)

Dera ndi kutalika kwa koyiloyo ndi mita. Mawu akuti mu ndi permeability wa pachimake. Mpweya umakhala ndi permeability ya 1, pomwe chitsulo chikhoza kukhala ndi permeability 2,000.

Kugwiritsa Ntchito Inductor: Zowunikira Kuwala Kwa Magalimoto

Tiyerekeze kuti mutenga waya wa waya womwe mwina 6 (mamita awiri) m'mimba mwake, wokhala ndi miluko isanu kapena sikisi ya waya. Mumadula mipope mumsewu ndikuyika koyilo m'mizere. Mumangirira mita ya inductance ku koyilo ndikuwona chomwe inductance ya koyiloyo ili.

Tsopano mumayimitsa galimoto pamwamba pa koyilo ndikuwunikanso inductance. Inductance idzakhala yaikulu kwambiri chifukwa cha chinthu chachikulu chachitsulo chomwe chili mu mphamvu ya maginito ya loop. Galimoto yoyimitsidwa pamwamba pa koyilo ikuchita ngati pachimake cha inductor, ndipo kukhalapo kwake kumasintha inductance ya koyilo. Masensa ambiri owunikira magalimoto amagwiritsa ntchito lupu motere. Sensa imayesa nthawi zonse kuyika kwa loop mumsewu, ndipo inductance ikakwera imadziwa kuti pali galimoto yomwe ikudikirira!

Nthawi zambiri mumagwiritsa ntchito koyilo yaing'ono kwambiri. Kugwiritsira ntchito kwakukulu kwa inductors ndikugwirizanitsa ndi ma capacitor kuti apange oscillator. Onani Momwe Oscillators Amagwirira ntchito kuti mudziwe zambiri.
