Element of slot thermal modelling

In this paper we present winding thermal model in electrical machine. To predict the temperature distribution accurately in the complex system winding, we propose to consider winding as a homogeneous and to simplify the model in using an equivalent thermal conductivity. To determine the value of this coefficient, we propose an experimental device that reproduces only the physical phenomena of heat transfer located in the slot. For the coupling between experimental measurements and calculations, we propose to use finite element analysis (FEA) to model conduction heat transfer.
