Some Like it Hot, But Not This Hot!

Hot? How hot is too hot? What happens to insulation when the motor gets too hot? What happens to the motor life when the motor gets too hot? How do you determine if it’s too hot? Answer: Testing, trending, and taking necessary action. Watch this case study to see the effect heat has on insulation and motors and how to be pro-active in order to reduce lost dollars.

Two to Tango

It takes two to tango and it takes two motors running at all times to avoid reducing capacity for this energy producing facility. This case study shows how an MCEMAX® tester was used to diagnose and monitor one motor with rotor bar damage until repairs could be made. Click on the button below to view this case study.

Multi-Technology Fault Identification
By Reggie Fett, MCA/IR Analyst
Reprinted with permission of Allied Reliability

This case study by Reggie Fett in inspired Source May 2013, Allied Reliability’s online newsletter, highlights the value of using multi-technology for motor analysis. The pump in question cannot be off line for more than three hours without causing production issues, making it imperative to quickly analyze and react to any test result anomalies. After routine testing the motor exhibited current and impedance imbalances. Read how multiple technologies were used to diagnose the problem.



Send This Motor to the "Clink"?
To get higher quality clinker, you need faster cooling. How do you assure that your clinker  IS cooled faster? Click on the image below to watch this case study about a hydraulic motor that is critical to the clinker cooling process and learn how an Egyptian cement company diagnosed problems with the motor, took action, and averted a costly, catastrophic failure.

Motor Repair or Replacement? The Green Solution
The ever present emphasis on technological efficiency is just one of several forces behind the pressure on companies to "go green" despite a trying economy. The ultimate criterion that determines whether a motor is truly green is energy efficiency. Technology, long the key to efficiency, can help resolve this issue through detailed computerized analysis of the motor, the power environment in which it operates, and even its reliability.

Platinum Plus - A South African Success Story
How do you prevent water from rising in a deep underground South African platinum mine? Answer: Make sure your pump motors are in good health. But what if one of the pumps is experiencing intermittent trips, creating fear that the mine will flood and shut down production? Watch this Case Study to learn how MCEMAX® prevented catastrophic motor failure. Click on the image below.

Case Study – Preventing Catastrophic Pump Failure
In-Rush/Start-Up test results were not normal. Demod test results compared to prior test results showed a ten times increase in noise level. Comparing test results from a like motor indicated something was wrong with the pump motor. To watch a video and learn how an alert CBM specialist at an electric utility prevented a catastrophic pump failure, click on the image below.

The Case of the Broken Bolt
The problem: A high current imbalance showed up during routine EMAX testing. The motor in question is important to operating the petrochemical facility at full capacity. Further evaluation of the motor by the technicians was needed. Click on the button below to watch a short video to learn how they responded to the test results and what they found.

Safe and Easy
It is safe, but there is nothing easy about donning all of the required personal protection equipment necessary to perform online electric motor testing. Helmet with face shield, goggles, two pair of gloves (rubber and leather), long-sleeves these all take time to put it on and they are bulky when you try to maneuver in small, cramped spaces.

Are you interested in an easier, quicker, but still safe, way to test electric motors online that doesn’t involve suiting up? Click on the Electrical Safety image below to view our safety presentation for an answer.
