An Investigation Into the Coupling of Magnetic and Thermal Analysis for a Wound-Rotor Synchronous Machine

Abstract

This paper is dealing with magnetic and thermal analysis coupling of a wound-rotor synchronous machine (WRSM) based on the equivalent circuit methods. The main objective of this work is to introduce the principles of both magnetic equivalent circuit (MEC) and thermal equivalent circuit (TEC) models, as well as the importance of their coupling. The results of nonlinear MEC are compared to 2-D finite-element analysis results obtained by the magnetic field analysis software JMAG while the results of TEC coupled with MEC are compared with the experimental thermal test results.
