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.
MotorDoc LLC presents the EMPATH, ECMS-1, and ECMS line of data collectors and continuous monitoring Electrical Signature Analyzers (ESA) for on and off-shore wind turbine generator, transformer, and powertrain analysis. With two decades of windpower experience on all major platform types. For information on how we detect wye ring fractures, go to Windpower Generation…

With the motor and pump located elsewhere data was collected from a VFD prior to entering motor or pump information. A loose connection was detected and corrected immediately with post-confirmation.
In this case study white paper we show the basics of trending a rotor bar fault and the various conditions surrounding the problem plus a view at the capability to look further than just the motor. The motor in question is a 4000hp, 1790 RPM, 4160 Vac, induction motor, gearbox and compressor. The fault was…
In this first case study we will review the capability of EMPATH ESA technology to detect a complex wind generator system from generator to blades. Contact us NOW at info@motordoc.com for more information!
