Tus thawj sab phenomenon ntawm induction neeg yog Michael Faraday, induction phenomenon yeej yog ib tug kauj ntawm conductive khoom (xws li tooj liab). Tam sim no ntws los ntawm lub kauj, thiab ib tug sib nqus teb yog generated nyob rau hauv thiab ib ncig ntawm lub kauj. Lub peev xwm ntawm lub magnetic teb ua nyob rau hauv lub kauj tsim thiab tus nqi ntawm cov tam sim no los ntawm lub kauj.
Cov kev taw qhia ntawm cov magnetic teb nyob rau hauv cov kev coj ntawm cov tam sim no. Yog li ntawd, qhov kev hloov nyob rau hauv cov kev taw qhia ntawm cov alternating tam sim no los ntawm cov kauj ua cov kev taw qhia ntawm cov magnetic teb yuav hloov, thiab tus nqi ntawm kev hloov no yog tib yam li tus nqi ntawm kev hloov ntawm cov alternating tam sim no. 50 Hz AC ua rau lub magnetic teb hloov 50 lub sij hawm nyob rau hauv ib tug thib ob. 400 kHz AC ua rau lub magnetic teb hloov 400,000 lub sij hawm nyob rau hauv ib tug thib ob.
Thaum ib tug workpiece ntawm conductive khoom muab tso rau hauv ib tug hloov magnetic teb (xws li ib tug sib nqus teb generated los ntawm ib tug alternating tam sim no), ib tug voltage yog generated nyob rau hauv lub workpiece (Faraday txoj cai). Lub ntxias voltage yuav coj tus khiav ntawm electrons: qhov no yog tam sim no! Tus tam sim no los ntawm lub workpiece yog opposite rau cov kev taw qhia ntawm cov tam sim no nyob rau hauv lub kauj. Qhov no txhais tau tias peb muaj peev xwm tswj tau lub zaus ntawm qhov tam sim no nyob rau hauv lub workpiece los tswj cov zaus ntawm qhov tam sim no nyob rau hauv lub kauj.
Thaum tam sim no kis tau los ntawm qhov nruab nrab, lub zog ntawm tus electrons encounters ib co kuj. Qhov no kuj yog manifested los ntawm tshav kub kub (Joule cua kub nyhuv). Txawm hais tias ntau dua cov kuj ntawm cov khoom rau lub khiav ntawm electrons li cov tam sim no kis tau los ntawm cov khoom, lub ntau kub yog generated, nws yog tseem tau mus sov lub mas conductive khoom (xws li tooj liab) siv ib tug ntxias tam sim no. Qhov no tshwm sim yog qho tseem ceeb heev rau induction cua sov.
Feem ntau hais lus, ib tug txheej ntawm induction cua sov system xws li: fais fab mov,
cua sov cev thiab dej txias ib feem.
Foundry, Forging, tempering, Quenching.etc
