4. Conclusion

The information presented in this article is primarily intended to help the reader in the preparatory phase of machine dimensioning.

Analysis of the thermal behavior of a rotating electrical machine today requires numerical modeling of the entire system and the phenomena operating within it. The temperature level reached by critical elements, in particular the winding insulation, depends on the heat sources generated in the system and the cooling technique used. It is therefore a priori necessary to simultaneously determine the dissipation generated and the temperatures that result from it, by integrating the cooling processes into this approach. For certain applications involving open machines in particular, the difficulty of this task leads us to decouple the approaches and proceed in successive stages. The complete thermal calculation is one such step....
