Abstract
The purpose of this study, optimization of a light weight structure was carried out for the vertical-type motor stator frame. In this study, in order to increase the accuracy of FEM model, conformity with the natural frequency doing research was performed by the basis vector method. Then, after carrying out the sensitivity analysis of a natural frequency and thickness change of each part material, , optimization analysis aiming at weight minimization was carried out. Consequently, as compared with the configuration, about 18% of weight reduction was attained conventionally.
