Abstract

This paper shows the results of permanent magnet eddy current loss, iron core loss and Copper loss of a surface permanent magnet synchronous machine. A thermal model for the temperature of all motor components is also presented in the paper. This PMSM will be operated at the voltage 700-1000V powered by the battery pack. So the losses are calculated separately at four different DC link voltages (700V, 800V, 900V, 1000V). The analysis shows that this motor should stop working to avoid damage at very low voltage.
