This paper estimates inductance profile well adapted to position sensorless control method based on the high frequency signal injection and proposes a direction to design for sensorless control in interior permanent magnet synchronous motor(IPMSM) having a high density output power. In sensorless control, controller calculates the position of rotor at smallest d-axis inductance from high frequency injection. In order to satisfy this characteristic, this paper designs a motor having a large magnetic loading and a small electric loading. Inductance is calculated by the FEM using frozen permeability method and voltage equations of d-q axis are used to analyze characteristics of IPMSM such as torque, output power, current angle and efficiency.
