Abstract :
This paper presents an improved modeling of vector magnetic property of electrical steel sheet based on Fourier series of measured B and H waveforms in the viewpoint of engineering application. In order to obtain smooth approximation of measured data, the B-spline interpolation is adopted to obtain the reluctivity coefficients in the proposed model. The accuracy of proposed model is verified with the experimental measurement data.
