Rotor Geometry Parameter Optimization of Synchronous Reluctance Motor Using Taguchi Method

In this paper the effect of rotor geometry parameters on the d-axis and q-axis inductance of synchronous reluctance machines is investigated and an optimum design parameter combination is achieved to improve the saliency ratio as well as the performance of drive system. The 2D finite-element model of synchronous reluctance machine is used to construct the Taguchi design of experiments. The level of importance of each design parameter on the response surface is determined by using the Taguchi algorithm and analysis of variance results. The confirmation FEM simulation results indicated that the torque to current ratio and steady state performance of synchronous reluctance machines are improved appropriately in comparison with initial design, by using the proposed Taguchi optimization methodology. Streszczenie. W artykule opisano wplyw parametrow geometrycznych wirnika maszyny reluktancyjnej synchronicznej, na wartośc indukcyjności w osiach d i q. Opracowano optymalny sposob doboru tych parametrow w celu ograniczenia asymetrii magnetycznej maszyny. W budowie modelu metodą Taguchiego, wykorzystano model elementow skonczonych w 2-D. Wykazano, ze parametry maszyny, wyznaczone metodą optymalizacji Taguchiego pozwalają na osiągniecie lepszych, w porownaniu z oryginalnymi, odpowiedzi prądowych oraz momentu mechanicznego.
