要約(英語): It is well known that magnetic properties deteriorate in constructed cores due to conditions stressed by riveting and welding during manufacturing process, punching and sharing in cutting process of the electrical steel sheets and so on. Therefore, it is important to know the relationships between the stress and magnetic property of the electrical steel in order to design the electrical machinery. In this paper, the local residual stress distribution on the cross section of the stator core in a rotating machine is measured with a X-ray stress measurement device. As the result, the difference of the residual stress distribution of each component is obtained in the teeth and core back of the stator core. In addition, we estimated the deterioration of the magnetic property in the teeth region. It was clarified that the magnetic properties of the electrical steel sheet is deteriorated due to the residual stress.
