This paper presents the design of the concentrated-winding IPM motor under saliency-based sensorless drive with a high-frequency signal injection. Finite element analysis is used to examine the influence of the IPM rotor geometry on the operating region during the sensorless drive. On the basis of this analysis, a design procedure has been established to obtain a suitable rotor geometry that can maximize the torque capability during the sensorless drive. The 45Nm 5.5kW 6 pole 9 slot IPM motor is optimally designed for general industrial application. The validity of the proposed design is experimentally verified by using the prototype.
