Multi-Objective Topology Optimization of Synchronous Reluctance Machines Considering Design for Manufacturability Aspects

Abstract

This work is about optimizing synchronous reluctance machines considering a topology optimization (TO) based approach. This technique gives more design flexibility when comparing with finding ideal parameters for predefined geometries. A consistent implementation is presented that significantly reduces the overall computational effort compared to classical TO. In addition, attention is paid to obtaining designs ready for manufacturing. By contrast to the majority of previous work, the analysis encompasses multiple often conflicting objectives relevant for manufacturers and consequent customers, i.e., efficiency, maximum torque, torque ripple, and power factor. Based on the derived results, an individual tradeoff can be found and new insights into optimal designs for various applications can be gained.
