Abstract

The self-sensing capability of an inset permanent magnet machine is investigated in this paper. Thanks to a specific simulation strategy, the variations of the machine saliency and the error angle are computed considering different rotor positions and different loading conditions. Parasitic effects as saturation and eddy currents in both permanent magnets and lamination are also included in the analysis. The approach here presented is useful during the design process of the machine in order to assess the self-sensing capability of the machine and its impact on the drive control scheme.
