Innovative E-Motor Technologies for E-Axles and E-Corners Vehicle Architectures Enabling Highly Efficient and Sustainable E-Mobility
摘要
The Horizon Europe projects EM-TECH and HighScape propose innovative solutions for electric traction machines and their WBG-based drives and components, to achieve higher energy efficiency, reduced volume and mass, as well as reduced cost. This paper outlines the main innovations of EM-TECH and HighScape, targeting a wide range of vehicle applications, including passenger cars and commercial vehicles. Specifically, EM-TECH deals with: i) modular designs of on-board axial flux machines (AFMs) for reducing the implementation costs of scalable centralised powertrains for electric axle (e-Axle) solutions; ii) in-wheel motors (IWMs) integrated with electric gearing, for expanding the high efficiency region of electric corner (e-Corner) powertrains; and iii) the use of permanent magnets deriving from recycling processes to improve sustainability. In parallel, HighScape targets the physical and functional integration of the power electronics of WBG-based traction inverters, onboard chargers, DC/DC converters, and electric drives for auxiliaries and actuators.
