In this study the effect of parametric variatıon of the pole-arc offset distance on the performance of a permanent-magnet synchronous generator (PMSG) used in wind energy applications has been investigated. Fourier analyses of the voltage wave-shapes that are obtained by the parametric variation of the pole-arc offset value have been made. The THD is determined for each voltage wave-shape. As a result of optimization study the efficiency and the output power have been kept approximately constant. The THD of the output voltage has been decreased
