New method for experimental modal analysis of hydrogenerator's stator core using the excitation from the Poles

New method for experimental modal analysis of hydrogenerator's stator core using the excitation from the Poles

The study of stator core vibrations generated by electromagnetic forces in electrical machines is of great practical and theoretical interest. An important part of the problem is the correct determination of mode shapes and eigen frequencies of the mechanical system. This work brings to discussion a...
