在大规模生产中，电机的制造过程不能随时间完全重复，导致尺寸上的分散不等于其标称值。然后，问题是将尺寸上的分散体联系起来，这对电机的性能是不确定的，以便评估它们的影响。为了处理不确定性问题，人们对随机方法越来越感兴趣，该方法包括用随机变量对不确定参数进行建模。事实上，这种方法使我们能够量化的不确定参数的可变性对感兴趣的数量的可变性的影响。在本文中，一个随机的方法与三维有限元模型耦合使用的爪极同步电机的性能上的制造工艺缺陷，如转子偏心和定子变形的影响进行了研究。
In mass production, fabrication processes of electrical machines are not perfectly repeatable with time, leading to dispersions on the dimensions which are not equal to their nominal values. The issue is then to link the dispersions on the dimensions, which are uncertain to the performance of electrical machines in order to evaluate their influence. To deal with uncertainty, there is a growing interest in the stochastic approach, which consists of modeling the uncertain parameters with random variables. In fact, this approach enables us to quantify the influence of the variability of the uncertain parameters on the variability of the quantities of interest. In this paper, a stochastic approach coupled with a 3-D finite-element model is used to study the influence of the fabrication process imperfections, such as the rotor eccentricity and the stator deformation, on the performance of a claw pole synchronous machine.
