Comparison Of Two-Dimensional Single Sheet Testers For The Measurements Of Vector Hysteresis And Magnetostriction Characteristics

The hysteresis properties of electrical steel sheet (ESS) is very helpful to develop new type electrical machines and improve their performance. Therefore, two-dimensional steel sheet tester (SST) is required to measure the hysteresis properties of ESS. This paper introduces a kind of square type SST, but this SST can only measure the non-oriented and grain-oriented ESS because the size of the specimen is not large enough. To measure highly grain-oriented ESS, a new round type SST which is designed to have broader region of uniform field and allows a larger specimen is proposed in this paper. Meanwhile, magnetostriction properties also can be measured by this round type SST.
