Abstract

Permanent magnet synchronous machines with fractional slot stator windings using the tooth coil technology require detailed investigations on the electromagnetic parameters due to a very low number of slots per pole and phase. Finite element analyses of such machines can provide many results and even allow for a comparison of both Y- and Δ-connected stator windings. However, a subsequent application of the frozen permeabilities method allows for a more detailed discussion of effects caused by both permanent magnets and armature stator currents in conjunction with angular rotor position and also different saturation levels. In particular, such detailed analyses are required for high performance electrical drive systems which operate under very fast changing load conditions and run in deep field weakening ranges additionally.

Zusammenfassung

Permanentmagnet-Synchronmaschinen mit Bruchloch-Zahnspulenwicklungen erfordern wegen der sehr geringen Anzahl von Nuten pro Pol und Strang detaillierte Untersuchungen zu deren elektromagnetischen Parametern. Numerische Analysen mit der Methode der Finiten Elemente liefern solche Ergebnisse und erlauben in Bezug auf diese auch den Vergleich von Stern- und Dreieckschaltung der Statorwicklung. Eine tiefergehende Behandlung dieser Ergebnisse kann durch die Anwendung der Methode der festgehaltenen Permeabilitäten oder Reluktivitäten erfolgen. Damit lassen sich die Einflüsse der Permanentmagnete und der Statorströme in Abhängigkeit von Rotorwinkellage und unterschiedlichen Sättigungszuständen näher darstellen. Insbesondere sind solche Detailanalysen bei hochausgenutzten Synchronmaschinen für die elektrische Antriebstechnik notwendig, wenn diese unter rasch wechselnden Belastungen auch im tiefen Feldschwächbereich mit dementsprechend immer anderen Sättigungszuständen betrieben werden.
