Abstract

In this paper the design, the construction and measurements of a permanent magnet excited Flux-Switching-Machine (FSPM) are summarized. The special features of the presented 28-pole, three-phase permanent magnet Flux-Switching-Machine as variable-speed industrial drive for 400 V Y, 45 kW, 1000 … 3000 rpm are a slotted ferromagnetic rotor with no windings and no magnets, twelve stator tooth coil windings and in circumferential direction magnetized stator magnets. Special attention is paid to the manufacturing of the FSPM as it has a very simple and robust rotor, however, requires a special construction for the stator.

Finally, measurement results of the designed FSPM machine are shown and compared to measurements of an already built permanent magnet synchronous machine (PMSM) of the same size and rating with segmented rotor surface mounted magnets.

Zusammenfassung

In diesem Beitrag werden die Auslegung, die Konstruktion sowie Messergebnisse einer permanentmagneterregten Flux-Switching-Machine (FSPM) zusammengefasst. Die Besonderheiten der hier vorgestellten 28-poligen, dreiphasigen permanentmagneterregten Flux-Switching-Machine als drehzahlveränderbarer Industrieantrieb für 400 V Y, 45 kW, 1000 … 3000 U/min sind ein wicklungsloser genuteter ferromagnetischer Läufer ohne Magnete, zwölf Statorzahnspulen und in Umfangsrichtung magnetisierte Stator-Magnete. Besondere Aufmerksamkeit wird auf die Konstruktion der FSPM gelegt, da diese einen einfachen und robusten Rotor besitzt, aber eine spezielle Konstruktion für den Stator benötigt.

Außerdem werden erste Messergebnisse der ausgelegten FSPM-Maschine beschrieben und mit den Messergebnissen einer bereits erprobten permanentmagneterregten Synchronmaschine (PMSM) gleicher Baugröße und Bemessungsdaten mit segmentierten Läufer-Oberflächen-Permanentmagneten verglichen.
