尽管直线电机（LM）越来越多地用于工业中以发展直线运动，但它们遭受两个主要缺点：低效率和低功率因数。这些缺点导致高能量消耗和输入电流的上升，并且占用传输线容量。本文提出了一种多目标优化方法，同时提高效率和功率因数。我们的方法使用机器的分析模型来计算效率和功率因数。它使我们能够研究各种电机规格对效率和功率因数的影响。电机参数和尺寸，然后可以通过使用遗传算法在适当的目标函数进行优化。结果表明，在电机性能的增强。我们已经使用了2-D和3-D的时间步进有限元方法来评估分析结果。结果的比较验证了我们的优化方法。
Although linear electrical motors (LMs) are increasingly used in industry to develop linear motion, they suffer from two major drawbacks: low efficiency and low power factor. These drawbacks cause high energy consumption and a rise in input current, and occupy transmission line capacity. We present a multiobjective optimization method to improve both efficiency and power factor, simultaneously. Our method uses an analytical model of the machine to calculate the efficiency and power factor. It allows us to investigate the effects of various motor specifications on the efficiency and the power factor. Motor parameters and dimensions can then be optimized by using a genetic algorithm in an appropriate objective function. The results show an enhancement in motor performance. We have used 2-D and 3-D time-stepping finite-element methods to evaluate the analytical results. A comparison of results validates our optimization method.
