Optimum design of PMA-SynRM for zero inductance of Q-axis and experimental verification

This paper deals with the optimum design of permanent magnet assisted synchronous reluctance motor (PMA-SynRM) for power improvement. The focus of this paper is found firstly a design solution through the comparison of torque density and d, q-axis inductance according to the rotor magnet and flux barrier shape, secondly, a mixed resolution with central composite design (CCD) is introduced and analysis of variance (ANOVA) is conducted to determine the significance of the fitted regression model. The proposed procedure allows the definition of the rotor magnet and flux barrier shape, dimensions starting from an existing motor or a preliminary design according to the rated wattage.
