Abstract: As the complex space shape of stator coil of hydrogenerator and the difficulty of design and modification,a knowledge template based and skeleton based parametric design plan is proposed.The template library of knowledge templates is classified,which is divided into standard parts template library and structure template library.To research the process of this design method,a design specification for series products is presented.Design based on skeleton technologe is studied.Though introducing skeleton and template,the rapid design of structure template parts is realized.Based upon summarizing the design knowledge of a stator coil of hydrogenerator die,the experiment shows the design is practical and effective.

Key words: knowledge template, skeleton, parametric design, stator coil
