ANALYSIS OF HETEROGENEITY OF ELECTRICAL STEEL

Slawomir Tumanski – Slawomir Baranowski

   The paper presents the methods of analysis magnetic field strength distribution above magnetized electrical steel: scanning method, sensors array or measuring magnetic field strength along one line. Various methods of analysis of obtained results are discussed: statistical analysis, digital signal processing – FFT analysis, digital image processing - pattern recognition methods or morphology based operations.

Keywords: electrical steel, material evaluation, steel homogeneity, scanning of magnetic field
