Abstract

This paper presents the design of saliency-based sensorless drive interior permanent magnet (IPM) motor for the general industrial application. To design accurately, considering magnetic saturation and cross-coupling effects are in FEA-based performance predictions. The reliability of the FE simulation is verified by experiment using a prototype. Then, the influence of the IPM rotor geometry on the feasibility region is examined. Consequently, the design guideline is established to obtain a suitable rotor geometry which can maximize the torque capability under the sensorless drive. Under the restricted specifications of dimensions and requirements, the 45Nm-5.5 kW 6-pole-9slot IPM motor is optimally designed. The validity of the proposed design is experimentally verified using the prototype.
