The evolution of transportation systems is an inevitable process, driven by technologies advancements and sustainability demands. As a result, the development of innovative powertrain solutions plays a crucial role into the automotive field, especially in an environment like the heavy-duty vehicles one. This study is based on a real case in collaboration with Iveco Group. The main goal of this work is to model and simulate a patented dual motor eAxle specifically designed for HDVs applications. This technology aims to integrate a Permanent Magnets Synchronous Motor with an Asynchronous Induction Motor. Since this is a beginning phase of this Iveco project, the primary objective is to assess the feasibility of this technology within the company's strategic plans for the near future and to identify potential modifications or integrations if necessary.
