Abstract :
This paper presents a novel flux barrier design of a torque ripple reduction in a saliency-based sensorless drive concentrated-winding interior permanent magnet synchronous motor (IPMSM). The motor is designed for general-purpose sensorless industrial drives and to fulfill the torque ripple requirement with the required maximum torque under the sensorless drive. The designed rotor has a V-shape magnet, and a circular flux barrier at the rotor yoke in the center of N- and S-poles. A 45-N · m-5.5-kW IPMSM has been manufactured to check the design validity. The validity of the proposed design procedure and the expected drive characteristics are experimentally verified by using the prototype.
