چکیده

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 wpływ parametrów geometrycznych wirnika maszyny reluktancyjnej synchronicznej, na wartość indukcyjności w osiach d i q. Opracowano optymalny sposób doboru tych parametrów w celu ograniczenia asymetrii magnetycznej maszyny. W budowie modelu metodą Taguchiego, wykorzystano model elementów skończonych w 2-D. Wykazano, że parametry maszyny, wyznaczone metodą optymalizacji Taguchiego pozwalają na osiągnięcie lepszych, w porównaniu z oryginalnymi, odpowiedzi prądowych oraz momentu mechanicznego. (Optymalizacja parametrów geometrycznych wirnika w synchronicznej maszynie reluktancyjnej – metoda Taguchiego).
