Thermal modelling of the Synchronous Reluctance Machine
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
In this paper two methods for thermally modelling the Synchronous Reluctance Machine (SynRM) have been developed and compared to measured data. The first is an analytical method for estimating the end winding temperature based on Brostr¨oms formula. Curve fitting to the measured data was done by Gauss-Newton estimation. The second method uses a lumped thermal network for steady state temperature estimation based on machine geometry. Thermal modelling of the machine parts are portrayed. The frame to ambient thermal resistance is derived from measured data. Friction and windage losses are calculated through measurement, the core losses are separated based on finite element calculations. The results for both methods show good agreement. A comparison between the different methods is made.
