摘要

介绍了直线感应电机的工作原理和电磁计算程序,采用引入惯性权重的粒子群优化算法,以直线感应电机功率因数和同步效率的乘积为优化目标函数,对电机的初级叠片厚度、初级槽深、初级槽宽、槽口宽和气隙大小进行优化.通过MATLAB软件编程运算,得出优化后的目标函数值与参数值,与优化前比较,有效实现了电机功率因数和同步效率的提高.%The working principle and electromagnetic calculation of linear induction motor were introduced. Considering power factor and synchronous efficiency as optimal objective function, using particle swarm optimization algorithm with inertia weigh to optimize the primary laminated thickness, primary groove depth, primary slot width slit width, and air gap size. After MATI.AB software programming operation, there were new objective function values and parameter values. Compared with the previous, the power factor and synchronous efficiency have been improved.
