This paper presents the reasons for error resulting from the position estimation method of sensorless control, and presents the proper inductance distribution of the Interior Permanent Magnet Synchronous Motor (IPMSM) for sensor-less-oriented design based on high-frequency voltage signal injection. In order to find a solution to this problem, the cause of the estimating position error is established, and the concept of IPMSM for sensor-less oriented design is proposed. In this concept, as the Total Harmonic Distortion(THD) of the phase inductance in specific load conditions is decreased, the rotor position is better estimated. The inductance distribution based on the high-frequency voltage signal injection is compared with the test results. Both the simulation error patterns and the experiments are presented to verify the validity of the established method.
