Abstract :
A thermal model of a totally enclosed water-cooled induction machine is presented. The axially and radially discretized physical regions of the machine are modeled in the object-oriented language Modelica. Additionally, the water-cooling jacket is modeled. The parameters of the thermal network are derived from geometric, physical, and empirical data. The main focus of the presented highly extensible model was to achieve a good compromise between accuracy and simulation performance. Simulation and measurement results of a 6-kW prototype induction machine are presented and compared.
