In recent years the thermal behavior of electric machines is an attractive research topic. Due to the complexity of the problem, several approaches that exploit FEM analysis have been developed and presented in literature. In this research a 3D thermo-fluid dynamic simulation of an electric machine equipped with rubber belts directly applied on its shaft has been performed through COMSOL Multiphysics software. Aim of this investigation is the temperature distribution map of the whole motor, especially on the shaft and on the finned heat exchanger that is mounted on it.
