This paper investigates the internal shape correctness of alternator stators occurring in high and low temperature storage tests. This kind of failure can affect the adequate operation of alternators since vibrations can occur during rotation of the other part of the alternator, the rotor. This error can reduce the efficiency of the alternator. The aim of this study is to examine the influence of different testing parameters, such as the temperature and the running time of the test, and whether or not the stator is equipped with a damping element. For the experiments we used the full factorial experimental design method. The measurement of the cylindricity of the specimens was done with a circular and position error measuring machine. From the measured data, special improvement ratios can be calculated in order to define the appropriate range of testing parameters that resulting greater deformity. A further aim is to compare the different cylindricity parameters and the features of theirs measured values.

本文研究了在高温和低温存储测试中交流发电机定子的内部形状正确性。这种故障可能会影响交流发电机的正常运行，因为在交流发电机的另一部分（转子）旋转过程中可能会发生振动。该误差会降低交流发电机的效率。这项研究的目的是检查不同测试参数的影响，例如温度和测试的运行时间，以及定子是否装有阻尼元件。对于实验，我们使用了完整的阶乘实验设计方法。用圆和位置误差测量机进行样品圆柱度的测量。根据实测数据 为了确定导致更大变形的测试参数的适当范围，可以计算特殊的改善率。另一个目的是比较不同的圆柱度参数及其测量值的特征。
