To reduce the significant impact of the transportation sector on the environment, developed countries worldwide have started a massive electrification of their car fleets with a high-volume production of the main components of the electric vehicle powertrain: the battery, the inverter, the electric motor, and the mechanical transmission elements. The electric motor is a central component of the powertrain, generally made of rare-earth magnets, copper, magnetic iron sheets (FeSi), aluminum and steel. Their massive production on a global scale will therefore have a considerable impact on greenhouse gases and on the depletion of resources. Moreover, the growth of energy costs and its probable scarcity in the future will constrain us to consider the energy consumed during the life cycle of the electric motor, especially during its design and its potential recycling.
The purpose of this thesis is to develop an eco-design methodology for electric motors by considering the entire life cycle. We will start by setting up a multi-objective and multi-physical eco-design methodology (with aging models) with iso-process considering the life cycle assessment (LCA) of an electrical machine. Then, we will work on reducing our 2D finite element calculation models to gain speed. We will end with different sensitivity studies to test the robustness of the developed methodology.
