Energy and Environment Impact from Machine Defects with EMPATH ESA
Electrical and Mechanical Defects in an electrically driven machine have a direct impact on energy consumption. This can be from sub-standard maintenance practices, such as misalignment or belt tension, or degrading components such as bearings, belts, impellors, gears, and other parts. In this article we will discuss a simple motor/pump combination on a Variable Frequency…
Setting Up a Pump Motor In EMPATH and EmpathCMS
This is example is long so that we can demonstrate the databases built into the EMPATH Electrical Signature Analysis software.
Winding Stress Detection with Electrical Signature Analysis
Low voltage and VFD driven electric motors will often have voltage stresses between conductors. In cases where this is severe, it is detectible as discharges in the airgap of the machine. In this paper we will review one of the applications associated with turn faults stresses in stator windings of induction. The discovery was originally…
Case Study Evaluation of a Cooling Tower Motor, Gearbox, Blades and Power Quality with EMPATH
The issues identified in this case study include a high 1X RPM which would be related to the misalignment found across the drive shaft from the motor to the gearbox. The peaks on either side of line frequency are at the output speed of the gearbox and the red arrows are indicators of blade issues. …
Rotor Bar Fault Trend with EMPATH Electrical Signature Analysis
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…
Wind Turbine Analysis with EMPATH and EmpathCMS Case Study
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!
