Sensorless speed control of inset type axial gap self-bearing motor using extended EMF

The goal of this paper is utilization of the state observer to research a new capability of controlling the axial gap self-bearing motor. Analytical and experimental evaluation for a sensorless speed vector control of a salient axial gap self-bearing motor is presented. The approach is based on the estimation of the extended electromotive force (EEMF) through a Luenberger Observer (LO) with help of reference voltages, measured stator currents and measured displacement. Experiment has been implemented based on dSpace1104 with two three phase inverters. The result is destined for introduction in this conference.
