Loss Distribution Analysis of 250 kW Traction Induction Motor Using Coupled FEM Preisach Model

摘要

This paper deals with the loss distribution analysis of 250 kW traction induction motor 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 condition a 250 kW traction induction motor. Computer simulation and experimental result for the efficiency using dynamometer show the propriety of the proposed method.
