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 this paper. The procedures for the thermal model setup 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 modeling have also been reported and discussed. The accuracy of the proposed thermal model with less than 7% incidence of error is considered more than reasonable, taking into account the complexity of the system under analysis.
