Acta Medica Okayama 35 5 1999 Improvements of single sheet testers for measurement of 2-D magnetic properties up to high flux density 3965 3967 EN Masanori Nakano Hidehiko Nishimoto Koji Fujiwara Norio Takahashi <p>Due to structural limitation, the currently proposed apparatus based on a single sheet tester (SST) cannot measure magnetic properties along arbitrary directions (so-called 2-D magnetic properties) of silicon steel at high flux densities. In this paper, significant improvements are carried out on magnetizing windings and auxiliary yokes of a double excitation type of SST. Furthermore, crosswise overlapped H-coils are introduced so that even an ordinary single-excitation type of SST can be applicable to the measurements of 2-D properties. It is demonstrated that 2-D magnetization property up to 1.9 T can be measured by using the newly developed SST's</p> No potential conflict of interest relevant to this article was reported.
