October 13, 2005 Motor Testing Tip
Synchronous Motor Testing
One of the most challenging areas to test on a synchronous motor are the rotor coils. Traditionally, the most effective method was to apply AC voltage (normally 120 Volts) across the coils and measure the voltage drop across each coil. Variations greater than 5% are considered poor and the coil(s) can be replaced. The problem has been the danger of applying the AC voltage, the requirement to disassemble the machine and time.
Modern Motor Circuit Analysis (MCA) technology utilizing phase angle (Fi) and current/frequency response (I/F) can provide a rapid fault detection. With this MCA test, all testing is performed directly through the stator windings. When testing, if the Fi phase tests vary more than +/- 1 point from average and/or the I/F phase tests vary more than +/- 2 points from average, turn the shaft at least 10 degrees. If the test results rotate, then a short exists in the rotating fields. If the test results show the original pattern, then the fault exists in the stator.
Once a fault is detected in the rotating fields, in order to detect which coil(s) are bad, an MCA impedance test is performed across each coil. Any impedance more than 5% different from an average coil indicates a shorted coil. While it is recommended that all of the coils are rewound, replacement of bad coils can allow the machine to be operated through to a planned shutdown.

October 13, 2005 Integration: A Reliability “Buzzword”?
We seem to be hearing more talk about “Integrated Reliability” – why?
DMSI has prepared a short article that explains why and breaks down the elements of an integrated reliability program. Learn about integrated reliability to ensure you make the correct choices.

October 13, 2005 Root Cause Analysis (RCA) Tip
IS RCA INDUSTRY SPECIFIC?
Many people believe that their choice of RCA methods will vary depending on the industry they are in. These people do not realize that true RCA has nothing to do with the environment, but its common denominator is the human being. The nature of the event is irrelevant. What is important is the logical, deductive discipline of the human thought process. The same thought process will be used whether a person is investigating an explosion of a crude unit in a refinery or an unexpected death in a hospital.

October 13, 2005 Pulley Alignment Tip
Laser Pulley Alignment
Always mount your laser line emitter on the smaller pulley, and put your magnetic targets on the larger pulley. This will give you better visual resolution and result in a more accurate alignment.

October 13, 2005 (Asset) Health Tip
Don’t overlook the daily walk around your plant and what it can pick up.
As well as the condition monitoring of selected critical machines for problems I walk around the plant on a pre set route Monday, Wednesday and Friday mornings first thing and take a “zonal” look at the bigger picture.
I have picked up potential failures that I would not have, if I had just concentrated on the gearboxes, motors and bearings.
It’s also a great way to enjoy the fresh air on a beautiful morning!

October 13, 2005 Reliability Centered Maintenance (RCM) Tip
How to Select Assets for RCM Analysis
Reliability Centered Maintenance is a structured process that requires people, time and resources. Because of these associated costs, RCM should first be applied where it will show a return on the money invested in training, performing the analyses, and implementing the tasks that come out of your analyses. Assets should be selected as candidates for RCM analysis based on Reliability Measures, in doing so we can then track the assets performance prior to, and then following the RCM Analysis.
Candidates for RCM should have a history of:
• Equipment Related Operational Losses
• Equipment Related Speed Losses
• Equipment Related Quality Losses
• Poor Environmental, Health and Safety Performance
Companies with successful RCM efforts use Reliability Measures to help select the right reliability tools to minimize key manufacturing losses.
