Cover Story: A highly integrated electric drivetrain module is presented which incorporates novel technologies in the fields of transmissions, electric machines, and power electronics. The chosen high-speed electric machine concept makes the module small, powerful, and efficient. Combining all components in one single housing leads to flexibility in terms of vehicle integration and makes it possible to combine the module with conventional or alternative propulsion technologies. Additionally, a holistic drive module design process is introduced which identifies those component specifications which result in the cheapest, most efficient or smallest module assembly.
