The paper analysis the changing of internal roundness of alternator stators which is caused by different (relatively higher and lower) temperature storage tests and calculated with statistic method. The specific power and efficiency of the automotive alternator can be significantly decreased due to this kind of failure as the extending stator points crash to the rotor, which cannot rotates adequate speed. The main purpose of this publication is to investigate the effect of thermal testing parameters (temperature, running time, set or not with damping element) on shape correctness. In this investigation, a specific algorithm and the full factorial experimental design method are used to plan and execute the experiment. The measurement of the roundness of the specimens is done with a circular and position error measuring equipment. Special improvement ratios are determined from the measured data to clarify the suitable range of testing parameters which results in greater deformity.
