Examination of Mechanism to Apply Stress in Vector Magnetic Property Measurement System under Biaxial Tensile Stress

Abstract

It is well known that magnetic properties of electrical steel sheet deteriorate due to stress in process of electrical apparatus. Therefore, it is important to clarify the relationship between the stress and the magnetic property of the electrical steel sheet. We develop new measurement system, which can evaluate the vector magnetic property under the biaxial stress. In this paper, the mechanism to apply the biaxial tensile stress is examined by measuring the principal stress. In addition, the vector magnetic property under the tensile stress of x and y direction is measured with the developed system.
