Abstract
A dynamic hysteresis model is used with a 2-D magnetic vector potential finite element formulation. The scheme models traditional eddy current, static BH and anomalous losses. The model is used to predict the BH trajectory and hence the losses for a FeSi lamination with a PWM type excitation. The experimental results show good agreement with the finite element predictions
