| Research Abstract |
In this research, we developed a new measurement system of magnetostriction of a electrical steel sheet under stress in order to control vector magnetic properties by applying mechanical stress. Then, a new six-axial strain gauge is developed to measure the stress and magnetostriction in the plane of the electrical steel sheet. In addition, the measurement method of the magnetostriction is examined by using a lock-in amplifier. It is possible to make the database of the two-dimensional magnetostriction under various stress and magnetic flux conditions. In addition, the relationships between the stress and the magnetostriction under the alternating and rotating magneticflux conditions was clarified by measuring the magnetostriction under the tensile and compressive stress.
