Abstract：A novel stress dependent vector magnetic properties measurement method of electrical steel sheet is proposed. The tension or compressive stress is applied by Linear Actuator along rolling and transverse direction. The uniformity of magnetic flux density is guaranteed by optimizing the dimension of magnetic yoke and its arrangement so that the measurement accuracy can be improved. In order to measure the vector magnetic flux density and magnetic field intensity, B probe and double compound H-coil are introduced and assembled inside a frame of bakelite. According to pointing’s theorem, the total specific iron loss of electrical steel sheet under different magnetization conditions can be calculated. Based on the proposed method, the vector magnetic properties of different magnetization angles, axial ratio and magnetic flux density level of the specified non-oriented electrical steel are measured respectively by applying tension or compressive stress along magnetization direction. According to the measurement results, the evolution rule of stress dependent vector magnetic properties of electrical steel sheet is summarized.
