Abstract

For the design of miniature electrical machines of high power density, it is necessary to measure magnetic properties of electrical s sheet at high magnetic flux density. The JIS standard single-sheet tester (SST) is insufficient to measure magnetic properties at h magnetic flux density around 2.0 T. In this paper, we have designed and developed an SST, which can excite high magnetic strength fi up to about 58 000 A/m. The accuracy of measurement of alternating current (ac) loss at high magnetization (55 000 A/m) is veril by measuring the eddy current loss of a copper plate comparing with the theoretical value. It is shown that the magnetic propertie nonoriented electrical steel sheet can be measured until 2.1 T.).
