Abstract: This paper presents measured vector magnetic properties and
two-dimensional magnetostriction of a non-oriented electrical steel sheet
(including a 6.5% SiFe sheet), a grain-oriented electrical steel sheet, an
Fe-based amorphous sheet, and a permendur sheet. These electrical steel sheets
have been widely used as a core material of electrical equipment. Because it is
difficult to reduce a building factor of a practical machine made of stress
sensitive materials, it is therefore important to understand detailed magnetic
properties and magnetostriction characteristics. In order to grasp the basic
magnetic properties, vector magnetic properties and two-dimensional
magnetostriction were measured in the alternating magnetic flux conditions in
the arbitrary direction. In this paper, the relationship among the magnetic
flux density vector, the magnetic field strength vector, and the
two-dimensional magnetostriction in the various electrical steel sheets under
alternating flux condition is clarified.
Keywords: Vector magnetic property, two-dimensional magnetostriction, iron loss, magnetic anisotropy
