抄録

This paper presents a numerical modeling method of two-dimensional magnetostrictions on a non-oriented electrical steel sheet and a grain-oriented electrical steel sheet under alternating and rotating magnetic flux conditions. Non-sinusoidal magnetic flux occurs in a core of electrical machines due to excitation conditions and magnetic anisotropy. Therefore, it is not easy to estimate the magnetostriction under this magnetic flux condition. Principal magnetostrictions of expansion and contraction have been derived from the measured 2-D magnetostriction under sinusoidal magnetic flux conditions. In the suggested modeling method, the principal magnetostrictions have been modeled using the E&S model. Because, coefficients are expressed as waveform, it is possible to model the 2-D magnetostriction on two different kinds of electrical steel sheet. The 2-D magnetostriction under non-sinusoidal magnetic flux condition has been estimated using the suggested modeling. The estimated and measured magnetostriction were in agreement. Thus, the validity of the suggested modeling method was confirmed.
