Influences of Design and Manufacturing on the Performance of Electric Traction Drives

摘要

The transformation to electric mobility is a major challenge for automotive manufacturers and suppliers, as their research and development departments are mainly familiar with conventional combustion-based powertrains and the experience has grown over the last century, but electric machines and the corresponding technologies are often unknown. To meet these requirements, this paper is intended as a guideline for developers facing the new field of electric traction drives. First, the known winding technologies are resumed. Subsequently, the influences of design and manufacturing on the performance of electric traction drives are discussed, based on a previous literature research. Thereby, the focus of this paper is on state of the art winding technologies, traction drive designs and powertrains, so some simplifications are made for these cases of application.
