Abstract Transformer cores are subjected to external stress and high-frequency excitation for a long time during operation, which leads to increasingly severe problems of vibration, noise, and loss. To further study the comprehensive magnetic properties of the grain-oriented silicon steel sheet under different frequencies and stresses, a platform for measuring the comprehensive magnetic properties of soft magnetic material is established. Firstly, the effects of tensile and compressive stress on magnetostriction, hysteresis loop and loss characteristics of the grain-oriented silicon steel at 50Hz are obtained by using a single-sheet tester and a stress-controllable device. Furthermore, the variation of the comprehensive magnetic properties of the grain-oriented silicon steel sheet is studied, and the influence of stress and different incentives on the magnetic, magnetostrictive and acoustic characteristics is analyzed. The measured results show that compressive stress rather than tensile stress greatly influences on the magnetic properties of the grain-oriented silicon steel sheet. Furthermore, the magnetostriction decreases with the increase of frequency under compressive stress, whereas the noise increases with higher frequency, harmonic content, harmonic order, and more immense compressive stress.
