Abstract:

We present a topology optimization framework for electric motors that maximizes the torque under the constraint of the torque ripple and the rotor weight. By projecting the rotor design onto a static background mesh at various orientations, the proposed method eliminates the need for remeshing, simplifying the handling of the relative motion between the stator and rotor. Furthermore, we explore interpolation factors that improve design exploration during optimization. A synchronous reluctance motor (SynRM) is optimized to achieve substantial torque improvement and ripple reduction, demonstrating strong potential for advancing high- efficiency SynRM design.
