Inductor yooneka ngati inendi chigawo cha electromagnetic induction chopangidwa ndi maginito opangidwa ndi maginito amtundu wa I ndi waya wamkuwa wa enamelled, omwe amatha kusintha ma sign amagetsi kukhala maginito.

Inductor yooneka ngati I yokha ndi inductor. Amachokera ku mawonekedwe a chigoba, omwe ali ofanana ndi mawonekedwe a I, ndi mphepo ya coil mu kagawo ka "I". Ma inductors athu wamba ndichip inductors, RF inductors,magetsi inductors, ma inductors amtundu wamba, maginito loop inductors, ndi zina zambiri. Lero, sitiyambitsa ma inductors awa. Ndi ma inductors otani? Ndiye inductor yooneka ngati I

Chithunzi chojambula cha Inductor Core

Monga imodzi mwa plug-in inductors, inductor yooneka ngati I siing'ono chabe, komanso yosavuta kuyiyika, yomwe ndi inductor yamtundu wa plug-in ndipo imatenga malo ochepa; High Q factor; The anagawira capacitance ndi yaing'ono; High self resonance pafupipafupi; Special kalozera singano kapangidwe, si kophweka kutulutsa chatsekedwa dera chodabwitsa.

TheInductor yooneka ngati ineamagwiritsa ntchito kondakitala kuti adutse voteji ya AC ndi yapano. I-woboola pakati inductance ndi chiŵerengero cha maginito flux ya kondakitala kwa panopa kutulutsa alternating maginito flux kuzungulira kondakitala pamene kondakitala akudutsa AC panopa. Inductor yooneka ngati I nthawi zambiri imagwiritsidwa ntchito pofananiza madera ndi kuwongolera khalidwe lazizindikiro, ndipo nthawi zambiri imalumikizidwa ndi magetsi.

Kukhazikika kwa inductor yofanana ndi I ndipamwamba kuposa ya inductors. Kudutsa kwaposachedwa kwa dera kumakhala kokhazikika, ndipo magwiridwe antchito amawongoleredwa kwambiri. Ntchito yayikulu ya Inductor yooneka ngati I ndikusefa ma siginecha, phokoso losefera, kukhazikika kwapano ndikuwongolera kusokoneza kwamagetsi, komwe ndi njira yabwino yothanirana ndi EMI. Lero, ndikufuna kugawana nanu za kapangidwe kake ndi mawonekedwe a Inductor wooneka ngati I.

Kapangidwe ndi kapangidwe ka I-shape inductor

Mapangidwe a Inductor wooneka ngati I amapangidwa ndi kuthandizira kokhotakhota kwa koyilo yamkuwa yamkuwa. Inductor yofanana ndi I ndi imodzi mwazinthu zamagetsi zamagetsi kapena chipangizo, chomwe chimatanthawuza: pamene kusintha kwamakono, ma inductors akuluakulu osasunthika kapena ma inductors osinthika (monga oscillating coil, koyilo yamakono yotsutsa, etc.) adzapanga mphamvu ya electromotive kukana. kusintha kwaposachedwa chifukwa cha induction ya electromagnetic.

Inductor yomwe imagwiritsidwa ntchito nthawi zambiri imawonedwa ngati yowongoka ya axial inductor, yomwe ili yofanana ndi axial inductor mosavuta kugwiritsa ntchito. Komabe, inductor yomwe imagwiritsidwa ntchito kwambiri ngati I-inductor imatha kukhala ndi mtundu wokulirapo wa inductance, ndipo yapano ikhoza kusinthidwa mwachilengedwe pakugwiritsira ntchito;

Nthawi zambiri, waya enamelled (kapena ulusi wokutidwa waya) mwachindunji bala pa chigoba, ndiyeno maginito pachimake, mkuwa pachimake, chitsulo pachimake, etc. amaikidwa mkati mkati mwa mafupa kuti apititse patsogolo inductance.

Mafupawa nthawi zambiri amapangidwa ndi pulasitiki, bakelite ndi zoumba, ndipo amatha kupangidwa mosiyanasiyana malinga ndi zosowa zenizeni. Ma coil ang'onoang'ono (monga ma inductors ooneka ngati I) nthawi zambiri sagwiritsa ntchito chigoba, koma amawonjeza waya wa enamelled pakatikati pa maginito.

Chithunzi cha inductor yooneka ngati I

Mawonekedwe a I-shape inductor

1. Yaing'ono ofukula inductor, akugwira yaing'ono unsembe danga;

2. Small anagawira capacitance ndi mkulu kudzikonda resonance pafupipafupi;

3. Mapangidwe apadera a pini ya kalozera sikophweka kuyambitsa dera lotseguka.

4. Tetezani ndi manja a PVC kapena UL omwe amatha kutentha kutentha.

5. Kutsogolera chitetezo chaulere cha chilengedwe.

Mawonekedwe a I-shape inductor

1. Mtengo wa inductance: 1.0uH mpaka 100000uH.

2. Chovoteledwa panopa: kutengera kutentha kutentha, si upambana 200C.

3. Kutentha kwa ntchito: - 20oC mpaka 80oC.

4. Pomalizira mphamvu: kuposa 2.5 makilogalamu.

Ntchito ya I-shape inductor

1. Kusungirako mphamvu ndi kusefa mu mphamvu zamagetsi kumapangitsa kuti gwero lowonetsera magetsi likhale lokhazikika.

2. Oscillation, yomwe imapanga gawo la oscillation mu gawo losinthira kuti liwonjezere mphamvu yamagetsi

3. Anti interference and anti interference: imakhala ngati kutsamwitsa kwa magetsi ndi njira yosiyana siyana inductor kuti ateteze zigawo za harmonic mu mphamvu yamagetsi kuti asawononge gridi yamagetsi ndi kusokoneza magetsi, akugwira ntchito yokhazikika.

Zida zambiri zamagetsi zimakhala ndi RF inductors. "Kuti tiyang'ane nyama, chubu lagalasi lomwe limayikidwa pakhungu la ziweto zathu limakhala ndi inductor mkati," adatero Maria del Mar Villarrubia, katswiri wofufuza ndi chitukuko wa Plummer Company. "Nthawi zonse galimoto ikayambika, kulumikizana kwa zingwe kumapangidwa pakati pa ma inductors awiri, imodzi mkati mwagalimoto ndi ina mkati mwa kiyi."

Komabe, monga momwe zida zotere zilili ponseponse, ma inductors a RF alinso ndi ntchito zenizeni. Mu dera lozungulira, zinthuzi zimagwiritsidwa ntchito limodzi ndi ma capacitors kuti asankhe pafupipafupi (monga oscillating circuit, oscillator controlled oscillator, etc.).

Ma inductors a RF amathanso kugwiritsidwa ntchito pofananiza mapulogalamu kuti akwaniritse mizere yotumizira ma data. Izi ndizofunikira kuti muwonetsetse kufalikira kwa data pakati pa ma IC.

Akagwiritsidwa ntchito ngati RF choke, ma inductors amalumikizidwa motsatizana kuti azikhala ngati zosefera za RF. Mwachidule, RF choke ndi fyuluta yotsika pang'ono, yomwe imachepetsa ma frequency apamwamba, pomwe ma frequency otsika sadzakhala opanda cholepheretsa.

Kodi mtengo wa Q ndi chiyani?

Pokambirana za momwe inductance imagwirira ntchito, mtengo wa Q ndi muyeso wofunikira. Q mtengo ndi index yoyezera momwe inductance imagwirira ntchito. Ndi gawo lopanda malire lomwe limagwiritsidwa ntchito kufananiza ma frequency oscillation ndi kutayika kwa mphamvu.

Kukwera kwa mtengo wa Q, kuyandikira kwa inductor kumayenderana ndi inductor yabwino yosatayika. Ndiko kuti, ili ndi selectivity bwino mu dera resonant.

Ubwino wina wa mtengo wapamwamba wa Q ndikutayika kochepa, ndiko kuti, mphamvu zochepa zimadyedwa ndi inductor. Mtengo wotsika wa Q umapangitsa bandwidth yayikulu komanso kutsika kwa resonance amplitude pafupi ndi ma frequency oscillation.

Mtengo wa inductance

Kuphatikiza pa Q factor, muyeso weniweni wa inductor ndiye kuti mtengo wake wa inductance. Pogwiritsa ntchito ma audio ndi mphamvu, mtengo wa inductance nthawi zambiri umakhala Henry, pamene maulendo apamwamba nthawi zambiri amafunikira inductance yaying'ono, nthawi zambiri mu millihenry kapena microhenry.

Mtengo wa inductance umatengera zinthu zingapo, kuphatikiza kapangidwe kake, kukula kwapakati, zida zapakati ndi kutembenuka kwenikweni kwa koyilo. Inductance imatha kukhazikika kapena kusinthidwa.

Kugwiritsa ntchito kwaInductor woboola pakati

Inductor yooneka ngati I nthawi zambiri imagwiritsidwa ntchito mu: TV ndi zida zomvera; Zida zoyankhulirana; Buzzer ndi alarm; Wowongolera mphamvu; Makina omwe amafunikira Broadband ndi ma Q apamwamba kwambiri.

Kupyolera mu kumvetsetsa pamwamba pa ntchito, makhalidwe ndi ntchito za Inductor yooneka ngati I, tingaphunzire kuti Inductor yooneka ngati I imagwiritsidwa ntchito kwambiri pa GPS yokhala ndi galimoto, DVD yokhala ndi galimoto, zipangizo zamagetsi, chojambulira kanema, kuwonetsera kwa LCD, kompyuta. , zida zapakhomo, zoseweretsa, zinthu za digito, zida zaukadaulo wachitetezo ndi zinthu zina zamagetsi.

Ngati mukufuna zambiri, chonde omasukaLumikizanani nafe.
