Indorerezini ibikoresho bya electromagnetic induction bigizwe na I-magnetique core skeleton hamwe ninsinga z'umuringa zometseho, zishobora guhindura ibimenyetso byamashanyarazi mubimenyetso bya magneti.

Induction I-I ubwayo ni inductor. Bikomoka kumiterere ya skeleton, isa na I-shusho yumuyaga hamwe numuyaga wa coil mumwanya wa "I". Inductors dusanzwe niindimuInductors ya RF,amashanyarazi, uburyo busanzwe bwa inductors, magnetic loop inductor, nibindi. Uyu munsi, ntabwo tugiye kumenyekanisha izo inductor. Ni ubuhe bwoko bwa inductors? Ngiyo inductor ya I.

I-shusho ya Inductor Core ifoto

Nka kimwe mu byacometse mu bikoresho, inductor ya I-ntabwo iri mu bunini buto, ariko kandi biroroshye kuyishyiraho, ikaba ari imashini icomeka kandi igafata umwanya muto; Ikintu kinini Q; Ubushobozi bwagabanijwe ni buto; Kwiyunvikana cyane; Imiterere yihariye y'urushinge, ntabwo byoroshye kubyara ibintu bifunze.

UwitekaIndorereziikoresha kiyobora kugirango inyuze AC voltage nubu. Induction ya I-ni igipimo cya magnetiki flux ya kiyobora nuyumuyaga utanga imbaraga za magnetiki zigenda zihindagurika ziyobora iyo kiyobora inyuze kuri AC. I-shusho ya inductor ikoreshwa muburyo bwo guhuza imirongo no kugenzura ubuziranenge bwibimenyetso, kandi muri rusange bifitanye isano no gutanga amashanyarazi.

Ihungabana rya I-shusho ya inductor irarenze iyo muri inductor rusange. Ibiriho byanyuze mumuzunguruko birasa neza, kandi imikorere nayo iratera imbere cyane. Igikorwa nyamukuru cya inductor ya I ni ugushungura ibimenyetso, gushungura urusaku, guhagarika ikigezweho no kugenzura imiyoboro ya electromagnetic, ikaba ari uburyo bwiza bwo guhangana na EMI. Uyu munsi, ndashaka gusangira nawe kubyerekeye imiterere n'ibiranga inductor ya I.

Imiterere nibigize I-shusho ya inductor

Urwego rwa I-shusho ya inductor ikorwa ninkunga ihindagurika yumuringa wumuringa. I-shusho ya I-imwe ni imwe mu miterere yumuzunguruko wa elegitoroniki cyangwa igikoresho, yerekeza kuri: mugihe impinduka zubu, inductors nini nini zihamye cyangwa inductors zishobora guhinduka (nka coil oscillating coil, coil resistance coil, nibindi) bizabyara ingufu za electronique zo kurwanya impinduka zubu kubera induction ya electromagnetic.

Indorerezi ikoreshwa cyane I-ifatwa nka verisiyo ihagaritse ya inductor ya axial, isa na inductor ya axial muburyo bworoshye bwo kuyikoresha. Nyamara, ibisanzwe bikoreshwa I-inductor irashobora kugira ubwoko bunini bwa inductance, kandi ibyubu birashobora kunozwa mubisabwa;

Mu bihe byinshi, insinga zometseho (cyangwa insinga zipfunyitse umugozi) zirakomeretsa kuri skeleton, hanyuma intangiriro ya magnetiki, umuringa wumuringa, icyuma cyuma, nibindi bishyirwa mumyanya yimbere ya skeleton kugirango irusheho kwiyegereza.

Igikanka gisanzwe gikozwe muri plastiki, bakelite na ceramika, kandi gishobora gukorwa muburyo butandukanye ukurikije ibikenewe. Utubuto duto duto duto (nka inductors I-I) muri rusange ntabwo dukoresha skeleti, ahubwo duhinduranya insinga zometse kumurongo wa magneti.

Igishushanyo cya I-inductor

Ibiranga inductor ya I.

1. Indorerezi ntoya ihagaritse, ifata umwanya muto wo kwishyiriraho;

2.

3. Imiyoborere idasanzwe pin imiterere ntabwo yoroshye gutera uruziga.

4. Kurinda hamwe na PVC cyangwa UL ubushyuhe bugabanuka.

5. Kuyobora kurengera ibidukikije ku buntu.

Ibiranga inductor ya I.

1. Indangagaciro zindangagaciro: 1.0uH kugeza 100000uH.

2. Ikigereranyo cyagenwe: ukurikije izamuka ryubushyuhe, ntirishobora kurenga 200C.

3. Gukoresha ubushyuhe bwubushyuhe: - 20oC kugeza 80oC.

4. Imbaraga zanyuma: zirenga kg 2,5.

Imikorere ya inductor ya I.

1. Kubika ingufu no kuyungurura mumashanyarazi bituma isoko yerekana amashanyarazi ihagaze neza.

2. Oscillation, ikora ikintu kinyeganyega mukuzunguruka kugirango uzamure voltage

3.

Ibikoresho byinshi bya elegitoronike birimo inductors ya RF. Maria del Mar Villarrubia, inzobere mu bushakashatsi n’iterambere ry’isosiyete ya Plummer yagize ati: "Mu rwego rwo gukurikirana inyamaswa, umuyoboro w’ikirahure washyizwe mu ruhu rw’amatungo yacu yo mu rugo urimo indimu imbere." Ati: "Igihe cyose imodoka itangiye, itumanaho ridafite insinga rizakorwa hagati ya inductor zombi, imwe imbere mu modoka indi imbere mu rufunguzo."

Ariko, nkuko ibice nkibi biboneka hose, inductors ya RF nayo ifite porogaramu zihariye. Mu muzunguruko wa resonant, ibyo bintu bisanzwe bikoreshwa bifatanije nubushobozi bwo guhitamo inshuro runaka (nkumuzunguruko uhindagurika, voltage igenzurwa na oscillator, nibindi).

Inductors ya RF irashobora kandi gukoreshwa muguhuza porogaramu kugirango ugere kuburinganire bwumurongo wohereza amakuru. Ibi birakenewe kugirango amakuru yimikorere neza hagati ya IC.

Iyo ikoreshejwe nka RF choke, inductors zihujwe murukurikirane mukuzunguruka kugirango zikore nka filteri ya RF. Muri make, RF choke numuyoboro muto-wo kuyungurura, uzahuza imirongo myinshi, mugihe imirongo yo hasi izabangamirwa.

Q agaciro ki?

Mugihe muganira kumikorere ya inductance, Q agaciro nigipimo cyingenzi. Q agaciro ni indangagaciro yo gupima imikorere ya inductance. Nibipimo bitagira urugero bikoreshwa mukugereranya inshuro zinyeganyega nigipimo cyo gutakaza ingufu.

Hejuru ya Q agaciro, niko hafi yimikorere ya inductor nicyiza cyiza kitagira igihombo. Nukuvuga ko, ifite amahitamo meza mumurongo wa resonant.

Iyindi nyungu yo hejuru Q ifite agaciro ni igihombo gito, ni ukuvuga imbaraga nke zikoreshwa na inductor. Agaciro Q gaciro kazavamo ubugari bwagutse hamwe na resonance yo hasi ya amplitude kuri no hafi yinyeganyeza.

Agaciro k'induction

Usibye Q ibintu, ibipimo nyabyo bya inductor nukuri agaciro kayo. Kubikorwa byamajwi nimbaraga, agaciro ka inductance mubusanzwe ni Henry, mugihe porogaramu nyinshi zikoreshwa mubisanzwe bisaba inductance ntoya cyane, mubisanzwe murwego rwa milihenry cyangwa microhenry.

Agaciro ka inductance gashingiye kubintu byinshi, harimo imiterere, ingano yibanze, ibikoresho byibanze hamwe na coil ifatika. Inductance irashobora gukosorwa cyangwa guhinduka.

Gushyira mu bikorwaInductor

Induction I-isanzwe ikoreshwa muri: ibikoresho bya TV n'amajwi; Ibikoresho by'itumanaho; Buzzer n'impuruza; Umugenzuzi w'amashanyarazi; Sisitemu isaba umurongo mugari hamwe na Q indangagaciro.

Binyuze mu gusobanukirwa haruguru imikorere, ibiranga n'imikorere ya inductor ya I, dushobora kumenya ko inductor ya I ikoreshwa cyane mumodoka yashizwemo GPS, ibinyabiziga byashyizwe kuri DVD, ibikoresho bitanga amashanyarazi, ibyuma bifata amashusho, kwerekana LCD, mudasobwa , ibikoresho byo murugo, ibikinisho, ibicuruzwa bya digitale, ibikoresho byikoranabuhanga byumutekano nibindi bicuruzwa bya elegitoroniki.

Niba ushishikajwe nibisobanuro birambuye, nyamuneka wumve nezatwandikire.
