This paper deals with induction machines analysis by finite element analysis (FEA) for position sensorless control drives based on rotating voltage carrier injection. In details, it focuses the analysis of the supply conditions of the machine, both the high frequency rotating voltage carrier and the fundamental frequency supply, for the optimal detection of the rotor slotting saliency effects. With...
The doubly-salient permanent magnet (DSPM) motor employing straight rotor and concentrated windings is conventionally operated by means of current chopping control in constant-torque region and angle-position control in constant-power region due to the trapezoidal back-EMF waveform. However, the rotor-skewing method can be used to improve back-EMF and inductances waveforms to be sinusoidal significantly...
This study investigates the dynamic characteristics of synchronous reluctance motor (SynRM), with segmental rotor structure, using finite element method in which the moving mesh technique is considered. The focus of this paper is the effective of on-line parameter identification system for position sensorless control of a SynRM under saturation and iron loss. Comparisons are given with angle of the...
