Vim li cas siv Silicon Steel Sheets

Piv txwv tias qhov sib nqus induction lub zog hauv cov tub ntxhais hlau yog B, lub peev xwm tsim los ntawm Faraday txoj cai induction yog E, thiab qhov eddy tam sim no poob generated yog, qhov twg R yog qhov tsis kam ntawm cov tub ntxhais hlau.

Yog hais tias raws li cov duab hauv qab no, nyob rau hauv cov kev taw qhia ntawm ntsug magnetic teb, cov tub ntxhais hlau yog muab faib ua N daim, thiab cov hluav taws xob rwb thaiv tsev yog nqa tawm ntawm txhua daim, ces cheeb tsam ntawm txhua daim yog 1 / N, thiab induced. muaj peev xwm generated yog E/N. Raws li eddy tam sim no kev taw qhia, qhov cross-sectional cheeb tsam ntawm txhua daim hlau tub ntxhais yog txo mus rau 1 / N ntawm qhov qub, yog li raws li cov qauv tsis kam, qhov tsis kam ntawm txhua daim nce mus rau N lub sij hawm ntawm qhov qub (tsis quav ntsej qhov kev hloov pauv. nyob ntev).

Tom qab ntawd qhov eddy tam sim no poob rau ib feem ntawm cov tub ntxhais yog:

Tag nrho qhov poob ntawm N core yog:

Yog li ntawd, lub thinner cov tub ntxhais yog muab faib, ntau qhov ntau ntawm daim, qhov ntau pom tseeb cov nyhuv ntawm eddy tam sim no poob.

Tau kawg, cuam tshuam los ntawm cov txheej txheem tsim khoom, cov ntawv tuab ntawm silicon steel tsis tuaj yeem ua tsis tiav.
