In order to achieve worldwide governmental climate change goals, the concept of automotive traction should be revised. This change can be significantly accelerated by Electric Vehicles (EVs), and can lead to higher well-to-wheel efficiency, as well as lower emissions. Considerable research and development on electric propulsion are currently proceeding to reach these goals. The concept presented herein is based on the notion that by reducing the number of powertrain components in an EV, its efficiency and reliability can be improved.

The characteristics of commercially available electrical machines are not optimized for vehicle traction applications. This dissimilarity is usually resolved by choosing the appropriate machine power for a given application and, by adapting the revolutions and torque range to the required dynamics, by means of field weakening in combination with a mechanical solution. Hence, the machine power and system weight are minimized, and the machine becomes suitable for EV propulsion.

The aim of this project is to minimize the energetic losses, and the complexity of components in the driveline of EVs to maximize the vehicle efficiency and reliability by means of Dynamic Machine Operation (DMO) in cooperation with modular power electronics.
