Abstract

In order to analyze magnetic characteristics of magnetic devices, it is necessary to accurately measure magnetic properties of an electrical steel sheet in arbitrary directions. In this paper, we developed a 2-D-single-sheet tester (SST) using diagonal exiting coils in order to improve the measurement accuracy under high flux condition. The measurement region of flux density B and magnetic-field strength H is examined for the accurate measurement. The magnetic properties of grain-oriented electrical steel sheet under alternating magnetic flux and rotating magnetic flux are measured using our system. The accuracy of measurement in the case of grain-oriented sheet is examined by comparing the measured results using 2-D-SST with those by using an ordinary SST under alternating flux excitation. The effect of positioning error of orthogonal B and H coils on measurement accuracy is also discussed.
