A property of the motor is produced by forming a harmonic frequency equivalent circuit as applying the extracted parameter. Efficiency and a maximum torque are verified by using the efficiency and the maximum torque as an object function. The shape of the rotor is optimized by repeating a verification step until the object function satisfies the required condition by resetting the shape of the rotor.
