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.
During a site visit along with Scott Burkhardt of #RDI, we were asked to investigate the cause of a noise from a casting mill. The DC motor operated the mill through two gearboxes then a slow speed shaft. Following #motionamplification on the first day, data was collected with an #EMPATH #electricalsignatureanalyzer from the DC drive. A comparison of operating speeds from the customer…
After putting EMPATH through months and months of trials in wind turbines for transformer to complete powertrain: Utility-scale solar plant drives and transformers: Riding the rails testing locomotive generators and traction machines: Complex pipeline troubleshooting: Even evaluating commercial transformers, lighting systems and power quality issues: A well-deserved rest testing a good old pump motor running…

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!
