Abstract :
In this paper, an analytical method for the calculation of power losses in FeSi laminations, taking into account skin effect and the ferromagnetic material nonlinearity, is used to compute iron losses. The electromagnetic field is assumed to be bidimensional, as it is the case in many applications in electrical engineering. The results of the analytical method used to solve the nonlinear diffusion equation are used as a starting point for the losses computation in the ferromagnetic material, using a losses separation model. The computation assumptions are detailed, and the results are discussed.
