Zero-speed sensorless drive capability of fractional-slot inset PM machine

Abstract: This paper investigates the capability of an inset PM motor with concentrated coils fractional-slot winding to be controlled by means of sensorless techniques using high frequency signal injection. The inset PM motor considered is a 12-slot 10-pole motor, whose performance has been obtained by means of both finite elements simulations and experimental measurements. It will be shown that the motor presents good performance to be controlled by sensorless techniques, and the expected performance agree with the ex… Show more

“…Common electromotive-force (EMF) models calculate the position at high speed but do not work at low speed or rather at standstill. At this range most methods base on anisotropic effects [6], [7]. The reliability of these start-up sensorless controls depends on magnetic saturation and reluctance.…”

“…The saliency based position sensorless control performance of the RSMs is compared to that of the FI-PM machines and the FW-IPM machine. Similar investigations are performed in [14] and [15] where individual machines are investigated without comparison to other types of machines. Also highlighted in this work is the saliency shift of different FI-PM machine rotor structures with and without asymmetric rotors.…”
