Abstract :
This work deals with the influence of magnetic saturation on machine´s parameters of a surface mounted permanent magnet synchronous machine driven by an ideal six-step three-phase inverter. In order to investigate and describe each machine´s parameter, a review on Frozen Permeability Method is developed. Further, a general machine design characteristics are presented. At last, some simulation by means of finite element method with Frozen Permeability Method are carried out taking into account that the machine is driven by an ideal square current waveform. The results for line inductance, flux-linkage waveform and its harmonic contents are shown and analyzed.
