摘　　要：永磁直线同步电动机在远距离、大推力应用场合中需要的中枢绕组和永磁体多,系统造价较高。针对该问题,文章以经济指标为目标,采用自适应参数调整和适应值定标相结合的改进遗传算法,通过选取优化变量、确定约束条件及目标函数,实现了永磁直线同步电动机的优化设计。对优化前后的电动机各性能指标进行分析比较后得出,该优化方法能够改善电动机的综合性能指标,提高电动机的推力,减小电动机的体积,从而降低了电动机的制造成本。Cost of permanent magnet linear synchronous motor is high in application situations of long distance and large thrust because it needs many central windings and permanent magnets. Aiming at the problem, the paper took economy index as target, adopted improved genetic algorithm which was combined with adaptive parameter adjusting and adaptive value calibration, and realized optimization design of permanent magnet linear synchronous motor through selecting optimization variable and determining constraint condition and objective function. After analyzing and comparing each performance index of motor before and after being optimized, it was gotten that the optimization method can improve comprehensive performance index of motor, enhance its thrust and decrease its volume, so as to reduce product cost of motor.
