The variation of the self-sensing capability of different type of electrical machines due to parasitic effects is considered in this papers. Thanks to a specific simulation strategy the variations of the machine saliency and the error angle are computed considering different rotor positions and different working points. It is shown that a large variation occurs in particular working points. The presented approach 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 control scheme adopted in the drive.

Abstract
The variation of the self-sensing capability of different type of electrical machines due to parasitic effects is considered in this papers. Thanks to a specific simulation strategy the variations of the machine saliency and the error angle are computed considering different rotor positions and different working points. It is shown that a large variation occurs in particular working points. The presented approach 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 control scheme adopted in the drive.
