N2 - Synchronous Reluctance machines are on the line to significant torque ripple development if they are not carefully designed. Since torque ripple causes vibrations and noise in electrical machines it is generally unwanted. In servo-applications with a great speed and position control importance, the torque ripple of the motor also is a main performance criterium and its reduction needs to gain special attention. In this paper the influence of the flux barrier shape and width as well as the flux barriers position on the torque ripple is studied. In order to reduce torque ripple, the effect of continuous and discrete rotor skewing of multiple flux barrier rotor is investigated by means of finite element method investigations which include all saturation and cross magnetization effects. As a result a design method to significantly reduce the torque ripple with slight effect on the average torque is shown.
