Systematic Metamodel-Based Optimization Study of Synchronous Reluctance Machine Rotor Barrier Topologies

Nowadays, due to the confidence in modeling tools and rapid product iteration, electric machine designers primarily rely on simulations. This approach reduces time cost is very useful when comparing different topologies. The prototype stage usually comes after depletion of all simulation resources. When designing a synchronous reluctance machine, first step selection rotor barrier type. literature provides several topologies but does not clearly state which one yields best performance. goal this paper determine variant for six-pole selected requirements using metamodel-based optimization approach. Seven with complexities were derived from circular, hyperbolic, Zhukovsky types (circular concentric, circular variable depth, hyperbolic fixed eccentricity, original Zhukovsky, modified depth equal depth). novelty proposed strategy systematic fair comparison significantly total weeks few days. Additionally, novel topology, merges qualities considered variants, was developed. An identical applied final results prove that type substantially affects performance machine. are achieved by topology. In relation worst (baseline) gain 14.9% power factor increased 0.61 0.67. additional study numbers layers (3, 4, 5) conducted four layers.
