Abstract :
This paper analyzes the effects of fractional pitch and distributed winding stators on self-sensing performance of PM machines. Three rotor configurations, an FW-IPMSM and two FI-IPMSMs, and two stator designs, distributed and concentrated windings, are presented to analyze the cross-saturation, secondary saliencies, saturation-induced saliencies and saliency ratio depending on the possible rotor and stator configurations. Finite element modeling (FEM) has been used to obtain a detailed understanding of the self-sensing performance of these machines.
