This paper presents a torque ripple reduction design of a concentrated-winding IPMSM with a new flux barrier for saliency-based sensorless drives. The proposed IPMSM is designed for use in general-purpose sensorless industrial drives. In order to reduce torque ripple, its rotor employs a V-shape-magnet arrangement and circular flux barrier which is placed at the center of a rotor yoke between N- and S-poles. A 45-Nm 5.5-kW IPMSM is manufactured as a prototype in order to confirm the design validity, and experimental studies using the prototype demonstrate the expected drive characteristics and validate the proposed design procedure.
