The previous study of PM motor torque ripple is generally considered that the current distortion is the root cause of torque ripple of PMDC motor, and it is AC motor or brushless motor, not considered the effect of EMF and PMDC motor. To solve the problem, using the voltage harmonic injection method to suppress the PMDC motor torque ripple, considered the effect of EMF and PMDC motor. Base on the theory model of round square PMDC torque ripple suppression method, apply the FEM method to analyze the current and torque ripple, the improvement target is the minimum of torque and current ripple, compare the injection voltage harmonic with different optimization targets, The study provide theoretical and simulation basis to make round square torque ripple suppression sample and achieve the torque ripple suppression target.
