N2 - Most conventional design methods for electric machines focus on single-point performance optimization based on empirical data and standard procedures using expert knowledge. This results in high safety margins leading to a reduction in performance and efficiency, higher costs as well as an over-or underdesign of the electric machine. In the process, the driving behavior and real operating points during the actual operation are not considered. Therefore, it is essential to consider real driving behavior, real operating points and application specific requirements in the overall design process of electric machines. The machine efficiency is defined by the different loss types in the efficiency diagram of the machine and the specific operating points are set using a specified driving cycle or real driving behavior. The so-called cycle efficiency is significant in considering the overall machine efficiency and the actual operating points of the machine. In this paper, an analysis of specific machine design levers is conducted that aims at increasing the overall cycle efficiency. It is based on different driving cycles for a specific application using the characteristics of different loss types during operation.
