“…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.…”

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.

“…Consequently, drive topologies which use fewer or no REM represent an important subject of current research activities in the field of electric drives, e.g. [6,7,8,9]. The major challenge here is that alternative topologies are often associated with lower power density resulting in reduced efficiency.…”

Despite numerous research activities, guidelines and regulations, the exploitation of energy and resource efficiency potentials at companies in the field of electric drive technology is still lagging behind. Existing catalogues of measures and research results are mostly too generic or too theoretic for companies, especially for small and medium-sized enterprises (SME). Thus, this paper proposes the development of a user-oriented software system that supports the consideration of sustainability aspects within the product and process development of electric drives. The core component of this concept is a knowledge-based system (KBS), which reveals the wide range of energy and resource efficiency potentials along the whole product life cycle. In particular, correlations that exist between the individual saving potentials are to be mapped. By presenting the general solution concept and current stage of development, this paper provides the basis for future research which should focus on the further elaboration and prototypical implementation of the system proposed here.

“…For the shortage of flux regulation capability in the PM machine, the hybrid excited machine is proposed, which add the electric windings based on the PM machines and could adjust the air-gap magnetic field [3][4][5]. The flux regulation capability of the HEM has always been the focus and difficulty, which has attracted many scholars to study it [6,7].…”

To further enhance the speed regulation range of the hybrid excited machine (HEM), the structure of a magnetic ring is optimized using a combination of the magnetic circuit method (MCM) and numerical analysis method in this paper, and a disc magnetic ring (DMR) is proposed. The magnetic density distribution of the proposed disc magnetic ring hybrid excited machine (DMRHEM) is compared to the radial-axial hybrid excited machine (RAHEM), and the superiority of alleviating a saturation problem in the proposed DMRHEM is determined. To improve the power density, the spoke-type permanent magnet (PM) rotor is applied. The influence of the proposed DMR on the HEM is analyzed, and the field adjustment capability of the proposed DMRHEM is better. Based on this, by combining the bypass principle, the analytical expressions for the relations between the rotor pole-pair number and the motor axial length/stator inner diameter (MAL/SID) as well as flux regulation capability are derived to further explore the superiority of the proposed DMRHEM. The influence mechanism of the rotor pole-pair number and the MAL/SID on the proposed DRMHEM is determined. The optimal MAL/SID and pole-pair number are obtained.
