Rotor Parameter optimization of Synchronous Reluctance Machine by Using Taguchi Method

This paper proposes the use of Taguchi method to optimize the rotor parameter to improve the saliency ratio of synchronous reluctance machine. The effect of rotor geometryparameters on the d-axis and q-axis inductance of synchronous reluctance machines is investigated and an optimum design parameter combination is achieved to improvethe saliency ratio as well as the performance of synchronous reluctance machine. The 2D finite-element model ofsynchronous reluctance machine is used to construct the Taguchi design of experiments. The level of importance of the each design parameter on the response surface is determined by using the Taguchi algorithm and analysis of variance results. The confirmation FEM simulation results indicatedthat the torque to current ratio and steady state performance of synchronous reluctance machines improved significantly incomparison with initial design, by using the proposed Taguchi optimization methodology.
