摘要：针对多因素、有误差、周期长的试验，正交试验法是一种行之有效的试验安排方法。将正交试验法应用于微电机的设计改进，不仅可以减少试验次数，缩短试验周期，而且大大节约了试验经费，提高了电机设计质量。通过实例说明了正交试验法在微电机设计中的应用。

Abstract:For many factors，error and long period experiment，orthogonal experiment is a kind of effective method.The application of orthogonal experiment can reduce the time of experiment，and  shorten the period of experiment，and retrench the expense of experiment and improve the quality of motor design.Through the examples,explained the design application of the orthogonal experiment in micro-motor in this paper.
