Raws li kev sib nqus hluav taws xob, cov hluav taws xob hluav taws xob tau muab faib ua ob hom: qhib hom sib nqus thiab kaw hom sib nqus. Cov kab hluav taws xob ib txwm muaj yog hom qhib sib nqus, thiab nws cov tub ntxhais hlau yog ua los ntawm cov ntaub ntawv silicon steel ntawm li 0.3 hli, thiab cov coils thib ob thiab thawj coils raug mob nyob ib ncig ntawm cov tub ntxhais hlau. Lub kaw sib nqus hom siv cov tub ntxhais hlau zoo ib yam li III los ua cua tshuab thawj kauj, thiab tom qab ntawd cua tshuab thib ob sab nraud, thiab cov kab hlau nplaum sib nqus yog tsim los ntawm cov tub ntxhais hlau los tsim lub kaw sib nqus.
