The three-dimensional parametric design of motor based on visual basic

With the rapid development of science and technology and increasingly competitive global market, the speed of products replacement is being accelerated and customers´ demands for the products become more diversified. Parametric Design of computer technology is the necessary measures which meet the demand of products diversification. What the designers need to do is just to make some changes in the design of different sizes of the same series on the basis of the similar design. Through the feature size of these parts are changed visually and rapidly, the three-dimensional part models of new products can generate. And then we can get the three-dimensional assembly models of new products by re-assembly. In addition, although a motor is taken as an example in this paper, the research method is also applicable to standard parts and other mechanical products with serial production.
