Characteristic Analysis of Permanent Magnet Assisted Synchronous Reluctance Motorfor High Power Application

고출력 응용을 위한 영구자석 매입형 동기 릴럭턴스 전동기의 특성해석

In this paper, finite element analysis for a PMASynRM is presented and the characteristic analysis of inductance and torque is performed under the effect of saturation. The focus of this paper is characteristic analysis of d and q-axis inductances and torque according to magnetizing quantity of interior permanent magnet for PMASynRM. The d and q-axis current component ratios, load angles of a PMASynRM are investigated quantitatively on the basis of the proposed analysis method and the experimental test. Comparisons are given with output characteristic curves of normal SynRM and those according to the load in PMASynRM, respectively. And it is confirmed that the proposed model results in high output power performance.
