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…
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. …
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!
Effective October, 2018, MotorDoc LLC and Framatome have entered into an agreement providing Continuous Monitoring Electrical Signature Analysis in the form of the EmpathCMS (EMPATH Continuous Monitoring System). EmpathCMS provides the ability to monitor your entire electric motor system from the inside out using the electric machine as the transducer covering incoming power to driven…
