| Abstract |
Losses analyses of laminated magnetic materials subject to non-sinusoidal magnetic flux arepresented. Comparative analyses on typical Fe-Si oriented and non-oriented grains andnanocrystalline materials are carried out considering the influence of harmonic phase shift andassociated B-H minor loops. Experimental measurements are performed to illustrate the B-Hcharacteristics behaviours. A special experimental effort is given on nanocrystalline material, whereSteinmetz coefficients are experimentally identified to analyse the performances of the improvedGeneralized Steinmetz Equation (iGSE) when phase displaced minor loops occur. It is proven that theiGSE is efficient in predicting nanocrystalline losses versus variable phase displaced harmonics. |
