Theoretical Analysis of Synchronous Machines with Displaced Reluctance Axis

Winzer, Patrick; Doppelbauer, Martin

This paper examines synchronous machines, whose excitation axis and reluctance axis can have an arbitrary angle. Basic equations for this machine type are set up and control strategies for maximum torque are derived. By using a normalized representation, it will be shown that machines with displacement angles of about 60° need up to 10% less permanent magnet material than conventional machines while yielding comparable motor performance.
