Static Eccentricity Faults Using Electrical Signature Analysis
Static Eccentricity (air gap) is a fault that is created when the rotor is not in the magnetic center of the stator. Static eccentricity can cause an increase in operating current, overheating, energy losses, and overloading of bearings...

Stator Mechanical Faults Using Electrical Signature Analysis (ESA)
A stator mechanical fault is created when the stator core becomes loose within the motor frame, or if the windings are loose between the stator slots. A loose stator core or winding over a period of time will cause...

Torsional Issues: Stop Guessing and Measure the Problems Directly
Failure mechanisms such as misalignment, balance, or lubrication issues can cause machinery failure. Many of these problems can be identified using standard non-destructive testing (NDT) methods including vibration analysis, infrared thermography, and tribology....

Use HD Technology to Manage the Risk of Bearing Faults
Overall vibration catches bearing damage very late, when there may be 0.1% of the bearing lifetime left. Traditional vibration, let’s say systems with poor signal-to-noise ratio...

Hear Failure from Miles Away
Experienced maintenance professionals can understand if a machine is healthy or not by walking up to it and using their senses – hearing, touch, smell, and sight. But this skill doesn’t scale when there are more plants than experts. This case study – a TechINSIGHT – shows how IoT maintenance solutions are helping machine analysts be in multiple places at once...
