Abstract: This paper presents a simplified thermal model for a wound rotor induction machine. The thermal model is based on lumped parameters and the analytical equations for their computation are provided in the paper. The procedures for the thermal model set up have been discussed and validated on a 3.8 hp wound rotor machine, comparing the predicted and measured temperature. Due to the complex cooling system adopted for the tested machine, the techniques for its modelling have also been reported and discussed. The accuracy of the proposed thermal model with a less than 7 percent incidence of error is considered more than reasonable, taking into account the complexity of the system under analysis.
