Given that nearly 23% of the global CO2 emissions is blamed on the transport sector, its electrification becomes crucial for reaching the 2050 Net Zero Emissions scenario. The key enabler to this purpose is a sustainable design and development of electric powertrain systems, aiming at cutting the overall greenhouse gases emissions during each of the different life-cycle stages of the design, including procurement, manufacturing, use, and recycle or disposal. To improve the electric drive sustainability, alternative solutions are considered, which partially or completely reduce the utilization of materials having high environmental load, e.g., aluminum for replacing copper in the windings and wound field rotor topologies as substitute to rare-earth permanent magnets. These aspects open up fresh challenges on the performances during operation of electric drives, which necessitate high power density and efficiency designs. Consequently, much attention is drawn to the co-design of motors and power electronics, using integrative optimization techniques, innovative cooling systems, and advanced control methodologies, thus increasing the overall system efficiency and power density and reducing the energy consumption during operation. Finally, the most recent manufacturing technologies, such as robotics for process automation and additive manufacturing for fast prototyping, can potentially contribute to cutting the CO2 emissions during the production, recycling and disposal life-cycle phases.


This special section aims to comprehensively contribute in the latest research advancements on the field of sustainable electric drives for transportation electrification.
