I-inductor imalunga nokulula njengoko icandelo le-elektroniki linokufumana - yicoil nje yocingo. Nangona kunjalo, kuvela ukuba i-coil yocingo inokwenza izinto ezinomdla kakhulu ngenxa yeempawu zemagneti zekhoyili.

Kweli nqaku, siza kufunda konke malunga nee-inductors kunye nokuba zisetyenziselwa ntoni.

I-Inductor Basics

Kumzobo wesekethe, i-inductor iboniswa ngolu hlobo:

Ukuqonda ukuba i-inductor inokusebenza njani kwisekethe, lo mzobo uluncedo:

Into oyibonayo apha yibhetri, ibhalbhu yesibane, ucingo olujikeleze intsimbi (etyheli) kunye nesitshixo. Ikhoyili yocingo yi-inductor. Ukuba uyifundile indlela i-Electromagnets eSebenza ngayo, unokuqonda ukuba i-inductor yi-electromagnetic.

Ukuba ubunokukhupha i-inductor kule sekethe, obuya kuba nayo sisibane esiqhelekileyo. Uvala iswitshi kwaye ibhalbhu ilayite. Nge-inductor kwisekethe njengoko kubonisiwe, ukuziphatha kuhluke ngokupheleleyo.

Ibhalbhu yesibane sisixhathisi (ukuxhathisa kudala ubushushu ukwenza i-filament kwibhalbhu ikhazimle - bona indlela iiBhalbhu zokuKhanya ezisebenza ngayo ngeenkcukacha). Ucingo olukwikhoyili lunoxhathiso olusezantsi kakhulu (lucingo nje kuphela), ngoko unokulindela xa ulayita iswitshi kukuba ibhalbhu ikhanyise kancinane kakhulu. Uninzi lwangoku kufuneka lulandele indlela ephantsi yokumelana ne-loop. Kwenzeka ntoni endaweni yoko kukuba xa uvala iswitshi, ibhalbhu ivutha ngokuqaqambileyo ize ke ibe luzizi. Xa uvula iswitshi, ibhalbhu ivutha ngokuqaqamba kakhulu ize iphume ngokukhawuleza.

Isizathu sokuziphatha okungaqhelekanga yi-inductor. Xa yangoku iqala ukuhamba kwikhoyili, ikhoyili ifuna ukwakha intsimi yamagnetic. Ngelixa intsimi yakha, i-coil inqanda ukuhamba kwangoku. Emva kokuba intsimi yakhiwe, umsinga unokuhamba ngokuqhelekileyo ngocingo. Xa iswitshi ivulwa, intsimi kazibuthe ejikeleze ikhoyili igcina iqukuqela yangoku kwikhoyili de intsimi idilike. Le yangoku igcina ibhalbhu ilayitiwe kangangexesha elithile nangona iswitshi ivuliwe. Ngamanye amazwi, i-inductor inokugcina amandla kwintsimi yayo yamagnetic, kwaye i-inductor ivame ukuchasana naluphi na utshintsho kwixabiso langoku elihamba ngalo.

Cinga Ngamanzi...

Enye indlela yokubona ngeso lengqondo isenzo se-inductor kukuba nomfanekiso-ngqondweni womjelo omxinwa onamanzi aqukuqelayo kuwo, kunye nevili elinzima lamanzi elinamapheyile alo antywila kumjelo. Khawucinge ukuba amanzi kumjelo akahambi ekuqaleni.

Ngoku uzama ukuqalisa ukuqukuqela kwamanzi. Ivili lokubheqa liya kuthambekela ekuthinteleni amanzi ukuba angahambi ade afikelele kwisantya samanzi. Ukuba emva koko uzama ukumisa ukuhamba kwamanzi kumjelo, ivili lamanzi elijikelezayo liya kuzama ukugcina amanzi ahamba de isantya salo sokujikeleza sihlehlise umva ukuya kwisantya samanzi. I-inductor yenza into efanayo kunye nokuhamba kwee-electron kwi-wire - i-inductor imelana nokutshintsha ukuhamba kwee-electron.

FUNDA NGOKUGQITHISILEYO

Henry

Umthamo we-inductor ulawulwa zizinto ezine:

Inani leekhoyili - Iikhoyili ezininzi zithetha ukuthotywa okungaphezulu.

Izinto ezibhijelwe ngeekhoyili (undoqo)

Ummandla we-cross-sectional of coil - Indawo engaphezulu ithetha i-inductance.

Ubude bekhoyili - I-coil emfutshane ithetha i-coil encinci (okanye i-overlapping) iikhoyili, oku kuthetha ukuba inductance ngaphezulu.

Ukubeka intsimbi kumbindi we-inductor kuyinika inductance ngakumbi kunomoya okanye nawuphi na undoqo ongenamagnetic.

Iyunithi esemgangathweni ye-inductance yi-henry. Inxaki yokubala inani le-henries kwi-inductor yile:

H = (4 * Pi * #Jika * #Jika * Indawo yekhoyili * mu) / (coil Ubude * 10,000,000)

Indawo kunye nobude bekhoyili buziimitha. Igama elithi mu kukungeneka kondoqo. Umoya une-permeability ye-1, ngelixa intsimbi ingaba ne-permeability ye-2,000.

Isicelo se-Inductor: IiSensors zokukhanya kweTrafiki

Masithi uthatha ikhoyili yocingo mhlawumbi iimitha ezi-6 (iimitha ezi-2) ububanzi, equlathe amaqhina amahlanu okanye amathandathu ocingo. Unqumle iigrooves endleleni kwaye ubeke ikhoyili kwimijelo. Ufakela imitha ye-inductance kwi-coil kwaye ubone ukuba yintoni i-inductance ye-coil.

Ngoku upaka imoto phezu kwekhoyili kwaye ujonge i-inductance kwakhona. I-inductance iya kuba nkulu kakhulu ngenxa yento enkulu yensimbi ebekwe kwintsimi yamagnetic ye-loop. Imoto emiswe phezu kwekhoyili isebenza njengeyona nto iphambili ye-inductor, kwaye ubukho bayo buguqula ukunyanzeliswa kwekhoyili. Uninzi lwezinzwa zokukhanya kwezithuthi zisebenzisa i-loop ngale ndlela. I-sensor ihlala ivavanya i-inductance ye-loop endleleni, kwaye xa i-inductance iphakama iyazi ukuba kukho imoto elindileyo!

Ngokuqhelekileyo usebenzisa ikhoyili encinci kakhulu. Olunye usetyenziso olukhulu lwee-inductors kukubambisana kunye ne-capacitors ukwenza i-oscillators. Jonga indlela ii-oscillators ezisebenza ngayo ngeenkcukacha.
