Abstract
AbstractThe simulation of eddy current losses in laminated iron cores by the finite element method is of great interest in designing of electrical machines. Modeling each lamination individually by the finite element method requires many elements and leads to an inappropriately large system of equations. A two-scale finite element method is proposed to efficiently compute the losses in laminated media with linear material properties. The approach for the two-scale finite element method based on the magnetic vector potential A is described. Its accuracy and the computational costs are evaluated by a representative linear finite element benchmark.
