电磁钢板广泛用于电动机等的铁芯。电动机铁芯的磁性能受到由螺栓束等引起的厚度方向上的压缩应力引起的变形的影响。系统地研究磁性能的报道很少，尽管详细检查磁性能的行为对于电动机的精确设计很重要，在本文中，无取向电工钢板的压缩应力和它的磁性能之间的相关性进行了测量，使用单片压缩在厚度方向上。此外，磁滞损耗和涡流损耗在厚度方向上的压应力下的行为进行了检查。
The electrical steel sheet is widely used in iron cores of motors, etc. The magnetic properties of a motor core are affected by the distortion due to the compressive stress in the thickness direction caused by bolt bundles, etc. There have been few reports of magnetic properties being investigated systematically, although the detailed examination of the behavior of magnetic properties is important for the precise design of motor, etc. In this paper, the correlation between the compressive stress and its magnetic properties of a nonoriented electrical steel sheet is measured, using a single sheet compressed in the thickness direction. Moreover, the behavior of hysteresis loss and the eddy current loss under the compressive stress in the thickness direction is examined.
