Proposal of Motor Improvement Design Method under Limited Conditions Using Taguchi Method

Abstract

In this paper, we present a optimal design method that reduces torque ripple, a cause of noise and vibration, when there is a limited condition that the shape of the rotor cannot be changed during the process of planning the improvement design of the motor in the general industrial group. To proceed with such an optimal design, the optimal design is carried out by using the Taguchi method among experimental design methods suitable for carrying out the optimal design under limited experimental conditions. To use the Taguchi technique, each characteristic is simulated by FEM analysis because the characteristic changes whenever an influencing factor is changed.
