Gear Box Failure on Cooling Tower Induction Motor Fan
The large motors in this power plant are attached to a gear box, which is attached to a cooling fan inside the cooling tower. All components are enclosed inside a shroud, making a visual inspection difficult and costly. A knocking noise, possibly coming from inside the shroud, was detected. But was it the motor or the gear box? Watch the video to learn how the problem was analyzed without disassembling the shroud.

Reducing Costs with ESA and MCA™ Technology
More than 300 million electric motors are used in infrastructure, large buildings, and industry globally. These motors account for about 2/3rds of the industrial power consumption. Electricity is required in almost all areas of the plant to provide the driving force that either operates the equipment that produces the products or provides the services that the plant’s equipment was built to perform..

Why MEMS Accelerometers Are Becoming the Designer’s Best Choice for CbM Applications
A small number of semiconductor manufacturers have overcome the noise, bandwidth and g-Range shortcomings commonly associated with MEMS sensors used in Condition-based Monitoring (CbM) by producing several medium and high-performance MEMS vibration sensors with the latter being comparable to piezo accelerometers.

Rotor Bar Fault Maintenance Issue: Vibration Sensor Alert
A 398 KW MV motor that runs a blower fan in a cement plant was showing strange behavior. The vibration equipment indicated vibration amplitudes that became chronic with the passage of time. The maintenance team, not knowing what the issue was, ran the motor until the bearings had to be replaced...

Using Motor Current Signature To Detect The Number Of Cracked Rotor Bars In Induction Motors
This presentation will not only focus on collecting current signature , but also will cover the analysis part of spectral data to determine the number of cracked/broken bars along with the severity level and needed corresponding corrective actions . This will be clearly shown through two real case studies in my plant for two 1.2 MW induction motors.
