Abstract

This paper deals with the eddy current loss reduction in a surface mounted permanent magnet synchronous machine. Numerical solution based on 2D finite elements method is used to compute eddy current losses in the permanent magnets. This calculation is integrated in an optimization process by genetic algorithm which aims to minimize eddy current loss in magnets according to stator slot shape. The proposed strategy is applied to the considered machine at no and full load conditions. In the second case, both distributed and concentrated windings are studied.
