Efficiency evaluation of PMASynRM vs. SynRM using coupling FEM & Preisach modeling

In high-speed applications of a SynRM, hysteresis loss can become the major cause of power dissipation. The focus of this paper is the efficiency evaluation relative to hysteresis loss, copper loss, etc. on the basis of load condition in a SynRM and PMASynRM. Also, TMS320C31 DSP installed experimental device and dynamometer are equipped and experiments are performed. Computer simulation and experimental results for efficiency show the propriety of the proposed a coupled a coupled finite element analysis arid Preisach model.
