Loss Analysis and Efficiency Evaluations of Synchronous Reluctance Motor Using Coupled FEM & Preisach Modelling

유한요소법과 프라이자흐 모델을 이용한 SynRM의 손실해석과 효율평가

This paper deals with the loss analysis and efficiency evaluations in a synchronous reluctance motor (SynRM) using a coupled transient finite element method (FEM) and Preisach modeling, which is presented to analyze the characteristics under the effect of saturation and hysteresis loss. The focus of this paper is the efficiency evaluation relative to hysteresis loss, copper loss, etc. on the basis of speed, load condition in a SynRM. Computer simulation and experimental result for the efficiency using dynamometer show the propriety of the proposed method.
