“…With the new system, complexity is taken from the hardware to the software and costs over the whole live-cycle can be easily saved. In addition to that the ISCAD is intrinsically electrically safe due to the low voltage level of 48 V [6].…”

Through its new technology the ISCAD system provides up to 300 kW with a safe-to-touch 48 Volt battery. This results in a high-performance drive that is intrinsically electrically safe. The novel machine design requires new concepts for power electronics, control systems, and integration strategies. Further degrees of freedom yield to challenges and even more important to possibilities for all kinds of applications. The innovation of the design will be explained and adjustments for power electronics and control will be worked out. The focus of this paper is the 3 rd generation of Intelligent Stator Cage Drive (ISCAD) prototypes. This first integrated and compact prototype has been used to re-equip a Geely Emgrand EV. The entire system and the mentioned process are described in detail. In addition, the in-house designed 48 V battery is highlighted. Simulations and measurements give an overall demonstration of the potential and the current status of the drive.

“…A conventional squirrel cage rotor is used, while the operating principle is that of an ASM. [37] By being able to adjust the pole pair number depending on the speed range, the ISCAD manages to keep slip low and to achieve notably better results in energy efficiency over a broad speed range than the ASM. Further advantages are high power density and good resource efficiency, as no PM are deployed and the wear is low.…”

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.

“…ultiphase induction machines have shown great advantages regarding torque density which can be improved thanks to simultaneous injection of different harmonics of stator current (non-sinusoidal currents) [1]- [4], and speed range which can be extended thanks to the polechanging technique (sequential injection of harmonics) [5]- [9]. Furthermore, multiphase machines are more adapted for A .…”

Multiphase induction machines are advantageous regarding speed range extension in comparison with three-phase induction machines. This paper investigates how to choose the connection between stator phases for a multiphase induction machine allowing to extend the Torque-Speed characteristic of the machine, for traction application. A nineteen-phase induction machine with special phase connection is proposed. This topology is compared to a three-phase machine, with the same global volume, using a Finite-Element approach. The results show a significant extension of the Torque-Speed characteristic horizontally, by speed range extension, and vertically, by maximum torque enhancement, thanks to the pole-changing operation with the chosen phase connection.
