  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,…

  There are many theories and a lot of good practices relating to storeroom management and more specifically, inventory management. We have written about many of these practices in this space. You can read about more about these best practices areas at the following links: Electrical storeroom assessments, what happens nextCritical spares, is your storeroom ready…

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 on…

  Polarization Index testing or PI testing is often misunderstood and misapplied. it’s a highly useful test to determine the health of motor insulation and in so doing, identify accumulations of contaminants and assess the physical health of the insulation. In short, polarization means to cause something to obtain polarity and this test causes molecules…

  Life in the electrical storeroom can be challenging for a lot of reasons. With orders to fulfill and check, vendors to manage, job orders to issue and more – the storeroom manager has his or her hands full. This post summarizes a recent survey we conducted of storeroom managers across our service area and…

The life of a storeroom manager is full of challenges. There is never enough hours to handle the constant changes and new activities that must be supported. In many plants we visit, the electrical storeroom is everyone’s help desk. The storeroom manager is never lonely, that’s for sure. In this post, we explore ‘a day in…

  VMI continues to be a productive technology to manage high moving items in many electrical storerooms, and for good reasons. Number one is efficiency. Electrical storeroom managers have a lot on their plates every day – from managing monthly budgets to providing the reporting their organizations expect to reconciling invoices and acting as the…

Why you should do a self evaluation of your electrical storeroom If you have an electrical storeroom that supports critical operations, chances are you’ve spent a great deal of time and money to equip your storeroom to serve those needs. You’ve reviewed the SKUs that are used on a regular basis, optimized your inventory levels…

  A sound stator core is the foundation of a good motor winding. As we discussed in the previous post on Core Loss Testing, this test is essential to determining the viability of a stator core prior to motor rewind. In this video, we explore how to properly conduct core loss testing, the warning signs…

Installing motor bearings correctly is critical to long bearing and motor life with optimal performance. This post explores procedures for proper bearing preparation and installation in order to minimize the possibility of bearing and motor failure. Many bearings fail or will fail upon installation if proper shop procedures are not observed. Proper bearing installation To…

    Insulation Resistance testing is one of the most basic motor electrical test procedures that can be conducted in the field or in the shop. Yet it’s often overlooked as a source of valuable information, and it’s often misapplied due to some misunderstood fundamentals that must be observed when conducting an IR test. This…

This is the first in a series of motor repair best practices videos from EECO. These videos will help dispel some common misconceptions about motor repair, and highlight best practices related to industrial motor repair. To understand best practices in motor repair, you need to know how what to look for in your motor repair shop, and what…

Lighting solutions for hazardous environments are unique from general industrial lighting in a number of important ways that makes them suited to locations where the threat of explosive, or combustible substances such as liquids, gases or ‘flyings’ are present or can be. As a result, these fixtures must meet class and division rating for each defined application. For a…

Amid all the excitement surrounding LED lighting – and there are plenty of reasons to be excited – there is also the hard reality of cost justification that customers must inevitably face and that EECO deals with in sorting out whether to recommend LEDs or another alternative that offers faster payback. To be clear, there are good alternatives to…

  Matching LED lighting to the challenge can be quite an effort especially with all the choices available for industrial and general purpose lighting from a myriad of companies offering products for this market. According to our lighting team, more than 600 companies in the U.S. provide LED fixtures for industry and general purpose. And that includes fixture manufacturers such as Acuity, Cooper by Eaton, Hubbell, Philips…

  We have all heard the advantages of upgrading industrial lighting to LEDs – lower energy consumption, much longer lamp life, reduced heat build up and better light ‘color’ among other benefits. If you’ve ever been in an older facility alight with sodium vapor lamps or other traditional lighting, you know what we’re talking about here. Odd looking,…
