“n”型电机最小气隙正态分布计算方法

Normal Distribution Calculation Method on Min. Gap of "n" Type of Motor

简述了"n"型防爆电机的最小气隙限值及影响气隙的主要零部件,利用正态分布法计算最小气隙值,并通过实例,比较该方法与一般方法的计算结果,证明用正态分布方法计算更趋符合实际情况。

Min. Gap limitations specified in national standard and international standards relat- ed to explosion protected motors with type of ＂n＂ are summarized . The minimum gap values are obtained by utilizing the normal distribution method with actual ensamples. Compared the results from normal distribution method and common method used, it is proven that the result from this method is better in line with the actual situation.
