Mphete ya maginito ya opanga maginito opangira mphete ndi chingwe cholumikizira chimapanga inductor (waya mu chingwecho amalangidwa pa mphete ya maginito ngati coil inductance). Ndi gawo lomwe limagwiritsidwa ntchito poletsa kusokoneza pamabwalo amagetsi ndipo ndilabwino pamaphokoso apamwamba kwambiri. Mphamvu yotchinga imatchedwa mphete yotengera maginito. Chifukwa nthawi zambiri amapangidwa ndi zinthu za ferrite, amatchedwanso mphete ya maginito ya ferrite (yotchedwa mphete ya maginito).

Pachithunzichi, kumtunda ndi mphete yophatikizika ya maginito, ndipo m'munsi mwake ndi mphete ya maginito yokhala ndi zida zokwera. Mphete ya maginito ili ndi mawonekedwe osiyanasiyana a impedance pama frequency osiyanasiyana. Nthawi zambiri, kutsekeka kumakhala kochepa kwambiri pama frequency otsika, ndipo kutsekeka kwa mphete ya maginito kumawonjezeka kwambiri pamene ma frequency amawonjezeka. Zitha kuwoneka kuti gawo la inductance ndilabwino kwambiri kotero kuti aliyense amadziwa kuti kumtunda kwa ma frequency azizindikiro, ndikosavuta kutulutsa. Komabe, mizere yazizindikiro zonse siyitetezedwa. Mizere yolumikizira iyi imakhala tinyanga zabwino zolandirira malo ozungulira. Mtundu wa zikwangwani zosokoneza kwambiri, ndipo zizindikirozi zimayikidwa pamwamba pa chizindikiro choyambirira chotumizira, komanso kusintha chizindikiro choyambirira chothandizira, chomwe chimasokoneza kwambiri ntchito yamagetsi yamagetsi. Chifukwa chake, kuchepetsa kusokoneza kwamagetsi (EM) kwa zida zamagetsi kwaganiziridwa kale. vuto. Pansi pakuchita kwa mphete ya maginito, ngakhale ngati chizindikiro chothandizira chikuyenda bwino, chizindikiro chosokoneza chapamwamba chikhoza kuponderezedwa bwino, ndipo mtengo wake ndi wotsika.

MD maginito ring inductance idayambitsidwa, gawo la inductance lilinso ndi ntchito zofunika monga zowunikira, phokoso losefera, kukhazikika kwapano komanso kupondereza kusokoneza kwa mafunde amagetsi.

Chachiwiri, gulu la inductance.

Zosankhidwa ndi ma frequency ogwirira ntchito:

Inductance imatha kugawidwa kukhala inductance yapamwamba kwambiri, inductance yapakati pafupipafupi komanso inductance yotsika molingana ndi ma frequency opangira.

Air core inductors, maginito core inductors ndi copper core inductors nthawi zambiri amakhala apakati pafupipafupi kapena ma frequency inductors, pomwe ma iron core inductors nthawi zambiri amakhala otsika pafupipafupi.

Zimagawidwa ndi udindo wa inductance:

Malinga ndi ntchito ya inductance, inductance imatha kugawidwa kukhala oscillation inductance, inductance correction, kinescope deflection inductance, blocking inductance, inductance fyuluta, isolation inductance, inductance compensed, etc.

Oscillation inductance imagawidwa mu TV mzere oscillation koyilo, kum'mawa-kumadzulo pincushion kukonza koyilo ndi zina zotero.

The deflection inductance of the picture chubu imagawidwa mu mzere wokhotakhota wokhotakhota ndi wokhotakhota kumunda.

Choke inductor (chotchedwanso choke) chagawidwa m'mafupipafupi kutsamwitsa, kutsamwitsa kwafupipafupi, kutsamwitsa kwa ballast yamagetsi, kutsamwa kwa TV pafupipafupi ndi kutsamwitsa kwafupipafupi kwa TV, etc.

Fyuluta inductance imagawidwa kukhala magetsi (mphamvu pafupipafupi) fyuluta inductance ndi high frequency fyuluta inductance, etc.
