方向性けい素鋼板の任意方向の磁化特性測定法

抄録

The measuring method and the experimental results of the magnetic characteristics in any direction for the oriented silicon steel are described in this paper. The single sheet tester for rotational loss has been used in order to simulate conditions existing in real devices. The flux of any direction is induced on specimen by exciting from X and Y directions in the same phase. The flux density was measured by the each search coils. The magnetizing force was measured by a double H-coil method. The outputs of the B-coils and the H-coils were treated by sending from the wave digitizer to the personal computer.
In X and Y directions components of magnetic characteristics, for small values of B all characteristics are the same. Only the saturation value changes, and it depends on the direction of flux.
