N2 - This paper presents a method for optimizing the efficiency of a surface permanent magnet (SPM) motor taking into account the carrier harmonics based on magnetic and electric networks. The eddy current loss in the magnets of the SPM motor, including carrier harmonics, is calculated with an electric network model. Then, an efficiency map of the SPM is created by using the proposed electric and magnetic network models to evaluate the motor efficiency. Finally, the efficiency of the SPM motor is optimized by changing the stator structure.
