A metric for evaluation of the performance of saliency-tracking self-sensing control of PM motor

Abstract

This paper presents a study on the performance of saliency-tracking self-sensing method for a permanent-magnet synchronous motor. It is shown that the high speed limit is a function of modulation harmonics and the extraction of the rotor information contained in the HF currents envelope as rotor speed increases. These effects degrade the rotor position… (More)
