Modelling of iron losses in salient pole permanent magnet synchronous motors

Today, for the same rated power and speed electrical drives we have a strong competitor to the induction motors. This one it is represented by permanent magnet synchronous motors (PMSM) with salient pole rotors. In this paper are presented dedicated analytical and numerical models for the iron loss effect over the motor performance. It is presented a comprehensive comparison between no-load and loaded conditions test data for all the models presented.
