    This paper presents an eddy current non-destructive evaluation system that can detect the thinning
    defect on metal specimen.
    We studied on an ECT for radiator structures, and concluded that in case of such structures, it is comparably easy for detecting thinning defect[1]. We clarified that the frequency characteristics of signal of single fin showed valid
    dependencies on the radiator thicknesses. Finally, we determined a thinning detection method using an additional metal bar, instead of single fin.
    A small piece of metal bar, namely called marker, is mounted opposite side of specimen, then ECT evaluations are performed. Multi-Frequency Excitation and Spectrogram Method (MFES) is used.

    変圧器や電動機など電気機器の鉄心材料であるケイ素鋼板の部分的な二次元ベクトル磁気特性を 計測する「ベクトル磁気特性測定プローブ」を開発する。電気機器の鉄損を低減させるには製造工程でモータのケイ素鋼板に加わる磁気特性劣化を回復/改善させる製造支援システムの導入が有意義である。そのためには内部応力により部分的に生じる磁気特性の劣化を正確に測定できる計測方法が必要である
