要約(英語): In recent years, the precise magnetic properties of electrical steel sheet are needed to develop high efficiency electromagnetic devices. An IEC standard single sheet tester is often used for the magnetic property measurement, especially for commercial transactions. But it is not accurate, so is not proper for the material evaluation based on its precise properties data. Therefore, we developed the measurement technique for the precise magnetic properties of electrical steel sheet. In this paper, two single sheet testers are shown. One is according to IEC standard (IEC-SST), and the other, the Stress load type-Single Sheet Tester (S-SST) is originally designed with our measurement technique for the precise magnetic properties. The key technology for evaluation of electrical steel sheet is proposed, using the S-SST and the IEC-SST. In particular, magnetic field strength distribution in measurement area inside exciting coil and solution of H coil specification difference are studied. And the magnetic properties of the S-SST and the IEC-SST are compared.
