This paper aims to improve the impact noise generated by the motor rotation cycle due to the dynamic imbalance of the connection axis between the motor and the reducer, which is the driving part of the column-type electric power steering system (CEPS). In general, there are regulations on the roundness and concentricity of the rotating shaft to reduce static imbalance, and a rubber damping coupler is applied between the motor's rotating shaft and the reducer's worm shaft to absorb dynamic imbalance, but this study confirmed impact noise according to motor design specifications and production line assembly conditions. The impact on the design factor was reviewed according to the stiffness conditions of the bearing supporting the motor and reducer worm shaft and the damping coupler rigidity, and the impact on the assembly factor was reviewed by randomly implementing the Parallel, axial, and angular misalignment conditions that may occur during assembly between the column and motor. As a result, noise-disadvantageous influencing factors were improved in design, allowing more robust design specifications to be applied to impact noise.
