Case Study Slightly Loose Bearing Fits and VFD Issues in Vertical Motor with EMPATH Electrical Signature Analysis

In-place testing was performed on a 350 horsepower, 460 Vac, 1780 RPM vertical motor (Figure 1) and EMPATH detected conditions associated with bearings, rotor and early winding stress were indicated.  The motor was removed for routine overhaul and the defects were investigated.
