摘　　要：针对１５Ｗ电容式两相逆变驱动系统成本高，效率低缺陷，以其效率为目标函数，建立了电机优化设计数学模型，介绍一种新的罚函数法和改进的模式搜索法。运用所介绍的方法对该电机进行了优化设计。结果表明，所用的优化方法可提高优化速度，适当增大电机气隙长，每槽导体数、铁芯长有助于提高系统效率。Concerning the high cost and low efficiency defect of the two phase capacitor type inverter-fed induction motor drive, the mathematics model of the optimum design on its motor is set up, in which its efficiency is the objective function. A new penalty function method and the improved pattern search method are offered. By using these methods, the optimum design on the motor is carried out, which shows that the methods can make the optimum design fast and properly increasing the gap length, the number of conductors per slot and the core length of the motor is helpful to raise the efficiency.
