TWO-DIMENSIONAL FEM-ANALYSIS OF EDDY CURRENTS LOSS IN LAMINATED MAGNETIC CIRCUITS

Purpose. One of the solutions of the problem of taking into account losses in laminated magnetic circuits caused by eddy currents was examined. The proposed solution is intended for use in specialized mathematical models, which are based on a two-dimensional description of the electromagnetic field....
