چکیده

Zusammenfassung Axialflussmaschinen eignen sich mit ihrer scheibenförmigen Bauweise gut dazu, eine hohe Drehmomentausbeute in Bezug auf das eingesetzte Aktivmaterial zu realisieren. Gleichzeitig erlaubt es der planare Aufbau, den Eisenkreis modular und möglichst einfach herstellbar gestalten. In diesem Beitrag wird Maschinenvariante vorgestellt, deren aus U‑Jochen UI-30-Kernblechen Steckspulen aufgebaut ist. Solche genormten Bleche 30 × 40 mm Außenmaß $$\times$$ × 10 Nutausschnitt werden normalerweise zum Bau von Transformatoren eingesetzt. Vorteile dieses Maschinendesigns sind einfache Herstellbarkeit Skalierbarkeit über die Anzahl U‑Joche. Nachteile Wirbelstromverluste Magneten Rotorscheibe, was nutzbaren Drehzahlbereich aufgrund erhöhter Magnettemperaturen einschränkt. Da ebenso PMSM-Radialflussmaschine Außenläufer herstellen lässt, erfolgt ein direkter Vergleich für beide Maschinenvarianten aufgebauten Prototypen anhand Messdaten. Drehmoment ist Radialflussmaschine im Vorteil, während Axialflussmaschine Rotorverluste, Materialbedarf besser abschneidet.
