We have focused on stress magnetic anisotropy in various magnetic anisotropy of motor core materials. We have been developed a system for measuring the magnetic property vector under the various magnetic flux and stress conditions in order to clarify the between the stress and magnetic property. In this paper, we will measure the vector magnetic properties of a non-oriented electrical steel sheet under alternating and rotating magnetic flux conditions by applying the uniaxial and biaxial tensile stress. It was clear that the stress magnetic anisotropy changes by applying the uniaxial and biaxial tensile stress. In addition, a method for controlling the magnetic properties of the core material is presented with a high-frequency induction heating.
