- Abstract:
- Recently many articles discussing about shaft voltage and bearing currents and about their influence on operating life and reliability of sliding and anti-friction bearings appeared. Negative influence of electric current passing through bearings is known from beginning of the last century but new problems were occured with assotiation of electric machines feeding from static frequency converters. And just this problem is described in the article. We want to show our results of laboratory experiments and mathematical analysis of bearings damage in this paper.
