Coils yawanci sun hada da kwarangwal, winding, Magnetic core da covering cover, da dai sauransu. A lokuta daban-daban, wasu na'urorin ba su da murfin garkuwa, wasu ba su da ma'aunin maganadisu, wasu kuma ba su da tsayayyen firam, iska kawai.

Mataki 1: kwarangwal

Abubuwan da aka saba amfani da su na kwarangwal sune yumbu, robobi, bakelite da kwali na lantarki. Kayan kwarangwal yana da wani tasiri akan inganci da kwanciyar hankali na coil, wanda aka zaba gaba ɗaya bisa ga yanayin aiki.

2. Iska

Yawancin iskoki ana yin su ne da wayoyi masu keɓe da aka raunata a kan bobbin. Ana amfani da keɓaɓɓun wayoyi tare da wayoyi masu ƙyalli da wayoyi na lantarki na ƙayyadaddun bayanai daban-daban. Gabaɗaya magana, mafi girman inductance da ake buƙata ta iska, yawan adadin iskar. Ya kamata a ƙayyade diamita na waya da aka zaɓa bisa ga ƙimar halin yanzu da ke wucewa ta cikin iska da ƙimar Q na coil. Lokacin wucewa na yanzu yana da girma kuma ana buƙatar ƙimar Q ta zama babba, yakamata a zaɓi diamita na waya mai kauri don ya yi kauri. Lokacin da inductance bai wuce ƴan microhenres ba, yawanci ana raunata iskar da tsabar tsabar azurfa da aka ɗora da azurfa don rage juriyar saman waya da haɓaka aikin nada.

3. Garkuwa

Don rage tasirin filin lantarki na waje akan nada da kuma gudunmawar filin lantarki da aka samar da na'urar zuwa kewayen waje, ana amfani da murfin karfe don rufe na'urar a cikin tsarin, kuma yana dogara da shi zuwa ga tsarin. cimma buƙatun warewa daga kewayen waje.

4. Magnetic core

Bayan da aka sanya coil a cikin core, za a iya ƙara inductance na nada, ko idan aka kwatanta da nada ba tare da core tare da wannan inductance, za a iya rage yawan coils tare da core, don haka rage girma da kuma rarraba capacitance. nada da inganta darajar Q na coil. Wani lokaci, don daidaita inductance na coil, ana iya gane shi ta hanyar daidaita matsayi na tsakiya a cikin coil. Ana yin muryoyin maganadisu yawanci da manganese-zinc ferrite ko nickel-zinc ferrite kayan maganadisu, kuma ana iya yin su zuwa siffofi daban-daban bisa ga buƙatun amfani daban-daban.
