The parameters and its influence on the winding design of an inductor was investigated, using Taguchi's method, with the aim of selecting an optimum set of parameters. An experimental design was use to determine the optimal combination of parameters corresponding to various contour designs that would result in minimum fall out ratio and minimum machine error processing. An orthogonal array factorial run was employed to determine an optimal set of parameters and to determine the influence of parameters such as wind start post, finishing angle, winding width and winding pitch on the performance. Based on the results from the analysis, it is concluded that the winding width is the most significant parameter related to fall out ratio. Additionally, the parameter winding width will define the optimum contour design in terms of geometry of design shape. © (2014) Trans Tech Publications, Switzerland.
