Abstract:

A computationally feasible methodology has been studied for the eddy current problem (ECP) in laminated iron cores of electrical devices. The multiscale finite element method (MSFEM) based on the magnetic vector potential has been exploited using the harmonic balance method (HBM) and a simple model order reduction (MOR) method. Several simulations by means of a numerical problem are presented demonstrating efficiency and accuracy of the proposed methodology.
