Novel strategy for the optimal design of induction motors

现有的对电机优化设计方法的研究主要是采用新的数值算法或对原有数值算法进行改进 ,而没有从电机设计公式本身出发做过研究。为了使现有的优化数值算法都能不经修改就应用到电机设计实践中 ,基于新的电机尺寸设计公式 ,提出了一种新的优化设计策略 ,对自变量进行了适当选取 ,解决了传统优化设计中需要考虑的离散变量问题 ,使全局收敛的可能性大大提高。对两个算例的优化计算表明 ,该方法是一种有效的优化设计方法 ,适用于各种优化算法的研究。

Most researching on optimal motor design has focused on new algorithms or improving existing ones. Seldom work has been done to get the improving design equations. This paper presents a new optimal design strategy based on new design equations. Through these equations, a group of continuous variables are selected. Thus the method has good global convergence and can handle discrete variables. It can be directly applied to almost all the optimization algorithms. The results show that the method is reliable and efficient.
