Abstract

It is known that the iron loss of the motor core made from laminated electrical steel sheets becomes worse due to compressive stresses applied in the manufacturing process. In order to perform quantitative analyses, we developed an apparatus that can measure the iron loss considering the compressive stress effect of an electrical steel sheet. In addition, we measured the iron loss by using the apparatus and evaluated the measured results. In this presentation, I will show the features of the measurement apparatus, and measurement results.
