It is known that the harmonic current of a motor affects torque ripple. Therefore, to take into account the harmonic current in finite element analysis, the voltage input needs to be evaluated however, voltage input analysis is more time-consuming than current input analysis. In this paper, we propose a method to predict the harmonic current and torque ripple of the voltage input analysis of the sine wave by only using the result of the current input analysis of the sine wave in the surface permanent magnet synchronous motor.
