This paper is dealing with magnetic and thermal analysis coupling of 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 two-dimensional (2-D) finite-element analysis (FEA) 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.
