“…However, existing work mainly focuses on energy and resource efficiency potentials of single phases of the motor's lifecycle, e.g. a resource efficient design [1,2,3,4], energy and resource efficient manufacturing processes [5,6,7] or energy consumption during operation [8,9,10,11], to name just a few. Thus, this paper summarizes sustainability aspects regarding electric motors from various perspectives, namely the market, product and process view.…”

“…This key figure sets the theoretical least energy demand 𝐸𝐸 𝑅𝑅𝑅𝑅 (including efficiency losses of the machine and the technology) of a process in relation to the actual energy consumption 𝐸𝐸 𝐶𝐶 . For example, the REE values of the processes within the stator production vary from 0.2 % to 68.2 % on machine level [5,6]. In the following, optimization approaches for contacting and impregnation processes as well as magnet manufacturing, transport, magnetization and assembly are summarized.…”

There are numerous levers and constraints affecting the sustainability of electric motors. While previous work mostly focuses on individual energy and resource efficiency potentials within single phases of the motor’s lifecycle, this paper summarizes sustainability aspects from three different perspectives, namely from the market, product and process view. The first part of this paper analyzes the electric motor market to emphasize the significance of this industry and to outline the importance of state-regulated efficiency classes. The second part provides an overview of the range of electric motor types and their sustainability characteristics. The third part contains an analysis of manufacturing processes in terms of energy and resource efficiency by pointing out appropriate key figures and optimization approaches. In doing so, the connection of the three perspectives market, product and processes offers a holistic view on sustainability aspects of electric motors.
