1. Kodi inductor ndi chiyani:
Inductor ndi gawo lamagetsi lomwe limasunga mphamvu ya maginito. Imavula ndi waya umodzi kapena zingapo, nthawi zambiri zimakhala ngati koyilo. Mphamvu ikadutsa pa inductor, imapanga mphamvu ya maginito, potero imasunga mphamvu. Chikhalidwe chachikulu cha inductor ndi inductance yake, yomwe imayesedwa mu Henry (H), koma mayunitsi ambiri ndi millihenry (mH) ndi microhenry (μH).
2. Zigawo zoyambira za aninductor:
Kolo:Pakatikati pa inductor ndi koyilo yopangira chilonda, yomwe nthawi zambiri imapangidwa ndi waya wamkuwa kapena aluminiyamu. Kuchuluka kwa matembenuzidwe, m'mimba mwake, ndi kutalika kwa koyilo kumakhudza mwachindunji mawonekedwe a inductance ndi magwiridwe antchito a inductor.
Maginito pachimake:Pakatikati ndi maginito omwe amagwiritsidwa ntchito mu inductor kuti apititse patsogolo mphamvu ya maginito. Zida zodziwika bwino zimaphatikizapo ferrite, ufa wachitsulo, nickel-zinc alloy, ndi zina zotero.
Transformer Bobbin:Bobbin ndi membala wamapangidwe omwe amathandizira koyilo, nthawi zambiri amapangidwa ndi zinthu zopanda maginito monga pulasitiki kapena ceramic. Chigobacho sichimangokhala ndi mawonekedwe a koyilo, komanso imakhala ngati insulator kuteteza mabwalo amfupi pakati pa ma coil.
Kuteteza:Ma inductors ena ochita bwino kwambiri atha kugwiritsa ntchito chotchinga chotchinga kuti achepetse kusokoneza kwamagetsi akunja ndikuletsa mphamvu yamagetsi yopangidwa ndi inductor yokha kuti isasokoneze zida zamagetsi zozungulira.
Pokwerera:The terminal ndi mawonekedwe omwe amalumikiza inductor ku dera. The terminal akhoza kukhala mu mawonekedwe a zikhomo, ziyangoyango, etc., kuti atsogolere unsembe wa inductor pa bolodi dera kapena kugwirizana ndi zigawo zina.
Encapsulation:Inductor ikhoza kutsekedwa mu chipolopolo cha pulasitiki kuti ipereke chitetezo chakuthupi, kuchepetsa ma radiation a electromagnetic, ndikuwonjezera mphamvu zamakina.
3. Zina zazikulu za ma inductors:
Inductance:Chikhalidwe chachikulu cha inductor ndi inductance yake, yofotokozedwa mu Henry (H), koma nthawi zambiri mu millihenry (mH) ndi microhenry (μH). Mtengo wa inductance umadalira geometry ya koyilo, kuchuluka kwa matembenuzidwe, zinthu zapakati, ndi momwe zimapangidwira.
DC Resistance (DCR):Waya mu inductor ali ndi kukana kwina, kotchedwa DC resistance. Kukaniza uku kumapangitsa kuti pakali pano kudzera mu inductor apange kutentha komanso kumakhudza magwiridwe ake.
Machulukidwe Panopa:Pomwepo kudzera pa inductor ikafika pamtengo wina, pachimake imatha kukhuta, zomwe zimapangitsa kuti mtengo wa inductance utsike kwambiri. Machulukidwe apano amatanthauza kuchuluka kwapakatikati kwa DC komwe inductor imatha kupirira isanakwane.
Quality Factor (Q):Ubwino wa chinthu ndi muyeso wa kutayika kwa mphamvu kwa inductor pafupipafupi pafupipafupi. Mtengo wapamwamba wa Q umatanthawuza kuti inductor imakhala ndi mphamvu zochepa zotaya mphamvu panthawiyi ndipo nthawi zambiri imakhala yofunikira kwambiri pamagwiritsidwe apamwamba kwambiri.
Self-Resonant Frequency (SRF):The self-resonant frequency ndi pafupipafupi pomwe inductance ya inductor imamveka motsatizana ndi mphamvu yogawidwa. Pazogwiritsa ntchito pafupipafupi, ma frequency odziyimira pawokha ndi gawo lofunikira chifukwa amachepetsa magwiridwe antchito amtundu wa inductor.
Idavoteredwa Panopa: Uwu ndiye mtengo wapamwamba kwambiri womwe woyendetsa amatha kunyamula mosalekeza popanda kuyambitsa kutentha kwakukulu.
Kutentha kwa Ntchito:Kutentha kogwira ntchito kwa inductor kumatanthawuza kusiyanasiyana kwa kutentha komwe inductor imatha kugwira ntchito bwino. Mitundu yosiyanasiyana ya inductors ikhoza kuchita mosiyana pansi pa kusintha kwa kutentha.
Core Material:Zomwe zili pachimake zimakhudza kwambiri magwiridwe antchito a inductor. Zida zosiyanasiyana zimakhala ndi maginito permeability, mawonekedwe otayika, komanso kukhazikika kwa kutentha. Zida zodziwika bwino zimaphatikizapo ferrite, ufa wachitsulo, mpweya, ndi zina.
Kuyika:Mapangidwe a phukusi la inductor amakhudza kukula kwake kwakuthupi, njira yoyikapo, ndi mawonekedwe a kutentha kwa kutentha. Mwachitsanzo, ma inductors apamwamba kwambiri (SMT) ndi oyenera ma board ozungulira kwambiri, pomwe ma inductors okhala ndi dzenje ndi oyenera kugwiritsa ntchito zomwe zimafuna mphamvu zamakina apamwamba.
Kuteteza:Ma inductors ena ali ndi mapangidwe otchinga kuti achepetse kusokonezeka kwa electromagnetic interference (EMI)
