Iron-Loss Computation Using Matlab and Comsol Multiphysics

In this paper, which is tutorial in nature, a description together with associated code samples is presented for predicting iron losses from a two-dimensional, finite-element model implemented using Comsol Multiphysics and Matlab. Two different conventional iron-loss models are presented and compared. The parameters for the adopted loss models are determined for an M250-35A-type steel and sample loss-density distributions are presented for different electric machine geometries.
