Diagnosis of distributed faults in outer race of bearings via Park's transformation method
The Park's transformation method has been used in this paper to analyze distributed defects
in the outer race of the bearing. The existing non-invasive motor current analysis and
instantaneous power analysis methods are unable to detect distributed defects in the
bearings, due the fact that characteristics defect frequencies models are not available for
these type of bearing defects. Thus, this paper proposes a graphical approach based on the
Park's transformation of three phase current to analyze bearing distributed defects. The …
