In our last post of this series on starting a condition-based maintenance program, we interviewed our Program Manager of Reliability Services Mike Rathbun, an integral part of the group that got this effort off the ground. Recently, Rathbun and his team conducted a training session around using the CBM worksheet that we reference throughout this…
Recently we published a series on condition-based maintenance (CBM) for motors, which is a core area for EECO. We wrote this series based on extensive feedback we’ve received as well as recommended textbooks. Our goal was to produce some condensed insights on maintenance and reliability. During this process, we also developed an eBook on CBM…
As shared in our last post, starting a new CBM program is tough. In our experience, the most successful teams tend to put in more work on the front end. This usually leads to the development of a business case. In this post we will explore the process to build the case, and how to…
In our last post of this series on condition-based maintenance, we discussed the financial guidelines of maintenance as well as some of the supporting KPIs. In this post, the sixth of the series, we will get into the nuts and bolts of starting a new condition-based maintenance program. We are all really busy. There is…
Last time we examined the concept of cascading objectives when starting a condition based maintenance program. In this post we will explore some of the financial guidelines of maintenance, as well as some of the supporting KPIs. Financial and metric guidelines At the highest level, manufacturers need a relative means to evaluate maintenance expense. This…
One of the first steps to starting a great reliability program or a simpler CBM program is simply understanding maintenance. This post will explore maintenance from a historical perspective and define some of the key terms. Understanding Maintenance Maintenance and reliability are professional fields with certifications available to highly trained personnel. There are numerous outlets for training; typically…
It is a well accepted fact that accurate bearing fit is critical to bearing life and run life of the motor. With more than 40% of motor failures related to bearings, this best practice cannot be emphasized enough, especially since the variables of bearing fits are easily controlled in the motor shop. For more,…
“We were then satisfied that, with proper lubrication and better adjustments a little more power could be expected.” — Orville Wright Bearings can be found in most anything that rolls, from skateboards to rocket motors in billion dollar space shuttles. When expensive motors fail, the results can be catastrophic. Electric Motors also keep industry in…
Surge testing helps identify a shorted motor conductor turn and as such is a powerful predictor of future motor failure due to turn-to-turn shorting. Failure of conductor insulation is the culprit here and is one of the first signs that a motor is going to electrically fail. The root cause is often insufficient insulation…
