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 magnetic property measurement, especially for commercial transactions. But it is not proper for the material evaluation based on its precise properties data. Therefore, we developed measurement techniques for the precise magnetic properties of electrical steel sheet. In this paper, the key technology for evaluation of electrical steel sheet is proposed. The single sheet tester based on evaluation measurement technique is useful for adequate choice of electrical steel sheet for high efficiency electrical devices and evaluation of high performance power magnetic materials, etc.
