Effect of Variation of B-H Properties on Loss and Flux Inside Silicon Steel Lamination

The effect of the variation of B-H properties obtained by different means and data access modes on iron loss and flux in grain oriented (GO) silicon steel laminations is investigated under different exciting frequencies in order to determine an efficient numerical approach to model the lamination configurations. The computational and experimental results are demonstrated on benchmark models in which the 3-D excitation and skin effect play a significant role.
