Abstract :
This paper presents a more accurate method to estimate the temperature distribution of the induction motor. Distributed heat sources are calculated by solving the voltage source eddy current problem. The analyzed model has several equivalent layers replacing the very narrow region such as the contact of frame and stator core. The numerical results shows the heat sources and temperature distribution well in a full FE analysis model
