In this paper, the shape of the rotor was analyzed to reduce the torque ripple of the traction induction motor. Induction motors have a lot of problems in manufacturing if the rotor has many slots. However, if the number of rotor slots are smaller than the number of stator slots, a relatively large torque ripple occurs. So, we keep the number of existing rotor slots and insert the auxiliary bar. This changes the characteristics of the torque ripple and magnetic flux density distribution. Auxiliary bars are inserted between the rotor slots and the material is copper. The optimization methods applied in this paper to reduce torque ripple and rotor slots are experimental design, response surface method, fast Fourier transform, and total harmonic distortion. As a result, it was analyzed that the torque ripple was reduced by using auxiliary copper bars.
