要約(英語): In estimating the iron loss of motor cores, it is important to grasp the magnetic properties of electrical steel sheets under applied stress and arbitrary flux conditions. We developed the apparatus to measure 2-D magnetic properties (properties under the arbitrary alternating and rotating flux conditions) of an electrical steel sheet in applying compressive stress normal to the surface. This paper describes the measured iron loss results of the electrical steel sheets with different grades under compressive stress normal to the surface, by using our developed apparatus. According to the measured results, it can be confirmed that the electrical steel sheet with low grade, whose iron loss is bigger, has a possibility to improve its iron loss by applying compressive stress normal to the surface.
