Design and experimental verification of saliency-based sensorless controlled ipmsm with concentrated winding for general industrial application

This paper presents the design and experimental verification of a saliency-based sensorless controlled IPMSM with concentrated windings for general purpose industrial drives. The IPMSM is designed by the proposed procedure so as to meet the torque ripple requirement with the required maximum torque. The designed rotor has a V-shape-magnet arrangement and circular flux-barrier which is placed at the center of a rotor yoke between N- and S-poles. An experimental IPMSM has been constructed based on the resulting design. The experimental studies using the prototype have proved the validity of the proposed design procedure and the expected drive characteristics.
