ABSTRACT

For this aim, an analysis of sources of machinery faults was widely discussed. On the basis of it, the significance of environmental issues on the performance of machinery was shown. Moreover, the investigation of working conditions in the European Union countries was made. In particular, the environment in Polish industrial companies was widely discussed in the period of last five years. It allowed to noticed that in most cases electrical motor faults were related to the most hazardous issues in working environment. Therefore, the machines should be robust design to environmental disturbances which may appear during their manufacturing and operation.
