Method of nonlinear magnetic field analysis taking into account eddy current in laminated core

In this paper, the method for modeling laminated core by a solid one is investigated. The method for taking into account eddy current in each steel plate used for laminating, which has already been developed in linear analysis, is expanded to nonlinear analysis by using one-dimensional finite-element analysis and the step-by-step method instead of the analytical solution and the phasor method, respectively. The effectiveness of the proposed method is shown by using a simple model.
