Abstract

This paper analyzes the effects of fractional pitch and distributed winding stators on the self-sensing performance of permanent-magnet machines. Three rotor configurations (i.e., a flux-weakened interior permanent-magnet synchronous machine (IPMSM) and two flux-intensified IPMSMs) and two stator designs (i.e., 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 has been used to obtain a detailed understanding of the self-sensing performance of these machines.
