Muab xam cov mis rau induction cua sov rauv

Cov mis rau xam qhov inductance ntawm cov cua-core coil: I = (0.01 * D * N * N) / (I / D + 0.44)

Qhov twg:

(1) Coil inductance I, chav tsev: microhenry;

(2) Coil txoj kab uas hla D, chav tsev: cm;

(3) Tus naj npawb ntawm cov kauj hloov N, chav tsev: tig;

(4) Coil ntev I, chav tsev: cm;

Raws li cov qauv, qhov inductance I yog proportional rau tus naj npawb ntawm lem N ntawm lub kauj.

Lub inductance kuv sawv cev rau cov yam ntxwv ntawm lub kauj nws tus kheej thiab tsis muaj dab tsi cuam tshuam nrog qhov loj ntawm tam sim no. Tsuas yog tshwj xeeb inductance coils (xim code inductance), qhov inductance feem ntau tsis yog cim tshwj xeeb ntawm lub kauj, tab sis cim nrog lub npe tshwj xeeb. Qhov loj ntawm inductor inductance feem ntau yog nyob ntawm seb muaj pes tsawg tus lem (ntau zaus) ntawm lub kauj, txoj kev winding, muaj lossis tsis muaj cov tub ntxhais sib nqus thiab cov khoom ntawm cov hlau nplaum, thiab lwm yam.

Feem ntau, qhov ntau coil tig thiab denser lub coils, qhov ntau dua qhov inductance. Lub coil nrog cov tub ntxhais sib nqus muaj qhov inductance ntau dua li lub kauj tsis muaj cov tub ntxhais sib nqus; Qhov ntau dua qhov permeability ntawm cov hlau nplaum, qhov ntau dua qhov inductance.

Lub hauv paus ntawm inductance yog Henry (Henry luv luv), sawv cev los ntawm tsab ntawv “H”. Cov chav tsev feem ntau siv yog millihenry (mH) thiab microhenry (μH). Kev sib raug zoo ntawm lawv yog: 1H = 1000mH; 1 mH = 1000 mH.
