ABSTRACT:
A process is performed for testing the quality of a unit such as an electromotor, which has at least one mobile part, which is mobile within a given frequency range with varying frequencies and is capable of exciting the unit to oscillate. In the method, a frequency of the mobile part at least within a first interval of the frequency range is varied with a first rate of change. The frequency of the mobile part within at least a second interval of the frequency range is varied with a second rate of change. The second rate of change is lower than the first rate of change. The oscillation amplitude of the unit is recorded and the unit is assessed as useful or unusable by evaluation of the recorded oscillation amplitude.
