Experimental identification and accurate model validation of the thermal model of an electric machine based on the finite elements method

The thermal model of the electrical machines is an important parameter in both the design of the drive system and in the optimization of the actual duty cycle of the machine. The thermal model is also useful to compute the actual load margin and for the on-line prediction of the faults into the electrical machine. In this perspective, for the on-line computations, the increase of the accuracy of the thermal model of the machine is important to obtain a consistent prediction of the fault. In this work, the author proposed a finite-elements-based method in purpose to obtain a reduced-order model of the heat process within the dynamic or the steady-state operation of the electrical machine.
