Coil ya air core
Mapangidwe apakati ndi kapangidwe kake
Zida zamawaya:nthawi zambiri waya wamkuwa kapena aluminiyamu (kukana otsika, kutsika kwapamwamba), pamwamba pakhoza kukhala siliva-wokutidwa kapena wokutidwa ndi utoto wotsekereza.
Njira yokhotakhota:mapiringa ozungulira (osanjikiza amodzi kapena angapo), mawonekedwewo amatha kukhala ozungulira, osalala (PCB koyilo) kapena mphete.
Coreless Design:koyiloyo imadzazidwa ndi mpweya kapena zinthu zopanda maginito zothandizira (monga chimango cha pulasitiki) kuti mupewe kutayika kwa hysteresis ndi kukhutitsidwa komwe kumachitika chifukwa chachitsulo chachitsulo.
Zofunikira zazikulu ndi magwiridwe antchito
Inductance:m'munsi (poyerekeza ndi zitsulo zapakati pazitsulo), koma zikhoza kuwonjezereka powonjezera chiwerengero cha matembenuzidwe kapena malo ozungulira.
Quality factor (Q mtengo):Q mtengo ndi wokwera pama frequency apamwamba (palibe iron core eddy yotayika pano), yoyenera kugwiritsa ntchito ma radio frequency (RF).
Kugawidwa kwapang'onopang'ono:Kuthekera kotembenuka kwa ma coil kumatha kukhudza magwiridwe antchito apamwamba kwambiri, ndipo mipata yokhotakhota iyenera kukonzedwa bwino.
Kukana:Kutengera mawaya ndi kutalika kwake, kukana kwa DC (DCR) kumakhudza kugwiritsa ntchito mphamvu.
Ubwino ndi kuipa kwake
Ubwino:
Kuchita bwino kwambiri pafupipafupi: palibe kutayika kwachitsulo, koyenera ma RF ndi ma microwave.
Palibe maginito maginito: inductance yokhazikika pansi pamakono apamwamba, oyenera kugunda ndi zochitika zapamwamba kwambiri.
Opepuka: kapangidwe kosavuta, kulemera kochepa, mtengo wotsika.
Zoyipa:
Low inductance: mtengo wa inductance ndi wocheperako kuposa wazitsulo zapakati pachitsulo pa voliyumu yomweyo.
Mphamvu ya maginito yofooka: imafunika matembenuzidwe okulirapo kapena ochulukirapo kuti apange mphamvu ya maginito yomweyi.
Zochitika zofananira ndikugwiritsa ntchito
Ma frequency apamwamba:
RF choke, LC resonant circuit, antenna yofananira network.
Zomverera ndi kuzindikira:
Zowunikira zitsulo, masensa apano osalumikizana (Rogowski coils).
Zida zamankhwala:
Zopangira ma gradient pamakina a MRI (kupewa kusokoneza maginito).
Zamagetsi zamagetsi:
Ma transfuriferi apamwamba kwambiri, ma coil oyitanitsa opanda zingwe (kupewa kutentha kwa ferrite).
Zofufuza:
Helmholtz coils (kupanga maginito ofanana maginito).
FAQ
Yankho: Ndife fakitale.
A: Tili ndi zaka 20 zopanga masika ndipo tikhoza kupanga mitundu yambiri ya akasupe. Kugulitsidwa pamtengo wotsika kwambiri.
A: Nthawi zambiri 5-10 masiku ngati katundu ali katundu. Masiku 7-15 ngati katunduyo alibe, ndi kuchuluka kwake.
