Abstract
In recent years the permanent magnet synchronous machine has become the state-of-the-art for various traction applications. A fast and accurate analysis methodology, using both the analytical and finite element method, that is suitable for use in an everyday design environment is required. Furthermore, collaboration between different locations and engineering groups mean that existing design tools need to be integrated into an existing tool-chain. A framework architecture that supports distributed system engineering, single component design processes as well as an engineering to order business approach is presented. Special attention is given to the critical sudden terminal short circuit fault condition.
Zusammenfassung
In den letzten Jahren ist die permanent erregte Synchronmaschine Stand der Technik in verschiedenen Traktionsanwendungen geworden. Dafür sind schnelle und genaue Berechnungsmethoden – sowohl analytische als auch Finte Elemente – erforderlich, die für eine Anwendung in der täglichen Arbeit geeignet sind. Um die Zusammenarbeit zwischen verschiedenen Entwicklungsstandorten und Abteilunge weiterhin zu gewährleisten, muss sich das Auslegungsprogramm in die existierende Toollandschaft eingliedern lassen. Es wird eine Arbeitsumgebung vorgestellt, die für arbeitsteilige Systemauslegung, Komponenten- und Auftragsentwicklung geeignet ist. Besonders wird auf den dreipoligen Stoßkurzschluss eingegangen.
