Sustainable and Efficient Motor Drive System for E-mobility Applications (SEMDY)
Research Project, 2022 – 2025

More than 70% of the energy losses in the electric vehicle propulsion system occurs in the electrical machine and the inverter. Additionally, elements with high values of Environmental Load Unit (ELU) are used in these two components. In this project, an advanced control of electrical machines toward improving inverter and electrical machine efficiency will be developed. The optimization process will not be limited to purely software and both the inverter and electrical machine hardware optimizations will be investigated. The optimization of the hardware will be done taking into account sustainability aspects of the different design alternatives, so that energy saving, and vehicle range is improved together with the development of a sustainable hardware in both electrical machine and inverter.
