Abstract (English): High-speed drives play a key role in many modern technologies, particularly in the field of fuel cells. However, the development of these drives represents a major technical challenge. The interactions between electromagnetic design, thermal conditions, rotor dynamics and strength must be considered. The development therefore requires close cooperation between different physical disciplines. Due to the high speeds and the required power density, the losses that occur must be modeled accurately. In addition, the development of efficient calculation methods poses a challenge with regard to computing time and optimizability. This paper provides an overview of the key components for efficient modelling of losses in high-speed drives and shows how advanced simulation techniques can contribute to the optimization of this complex system technology.

Abstract (German): Zusammenfassung: In vielen modernen Technologien, insbesondere im Bereich der Brennstoffzellen, spielen Hochgeschwindigkeitsantriebe eine Schlüsselrolle. Die Entwicklung dieser Antriebe stellt jedoch eine große technische Herausforderung dar. Insbesondere müssen die Wechselwirkungen zwischen elektromagnetischem Aufbau, thermischen Bedingungen, Rotordynamik und -festigkeit berücksichtigt werden. Die Entwicklung erfordert daher eine enge Zusammenarbeit verschiedener physikalischer Disziplinen. Aufgrund der hohen Drehzahlen und der geforderten Leistungsdichte müssen die auftretenden Verluste besonders genau modelliert werden. Darüber hinaus stellt die Entwicklung effizienter Berechnungsmethoden eine Herausforderung dar, insbesondere im Hinblick auf Rechenzeit und Optimierbarkeit. Dieses Paper gibt einen Überblick über die Schlüsselkomponenten für eine effiziente Modellierung der Verluste in Hochgeschwindigkeitsmotoren und zeigt, wie fortschrittlich Simulationstechniken zur Optimierung dieser komplexen Systemtechnologie beitragen können.
