When equipment in your plant malfunctions, you need to isolate the trouble quickly. Is the problem in the motor, or the starting circuit? In the August 2005 issue of PLANT ENGINEERING, “Take a step-by-step approach to analyze motor starting problems” looked at an organized process for troubleshooting electric motor starting problems.
Motor failure is never a good thing, and it always occurs at the worst possible time. If there's a bright side, it's the chance to evaluate your repair and replacement options and "get it right" for the long pull. To make the best of this opportunity, you need to be aware of the available repair options and follow a logical process for making motor repair vs. replacement decision.
Editor’s note: look in the February issue of PLANT ENGINEERING magazine for more information on disaster recovery as well as exclusive coverage on how one company bounced back from the devastation of Hurricane Katrina. In the popular mind, water and electricity are considered incompatible, and for good reason.

Inflation in operating materials and supplies has taken off, but the way that any single supplier handles the situation varies widely. Consider the vastly different outcomes in the steel wire and lubricating oil industries. Drawn steel wire prices increased 23.6% over the last 12 months, but did so without widespread support across major product lines.
If we were told that we could lower our home energy bills by up to 50%, most of us would jump at the opportunity. That could mean an extra $1,000 in our pockets, instead of in the pocket of the utility company — a significant annual saving. Look at a similar industrial plant scenario. Many industries are extremely pump intensive.
Each year, manufacturers lose nearly $20 billion — or almost 5% of total production in North America — due to unscheduled downtime. Despite the increasing sales of data collection systems, this loss suggests that manufacturers still don’t know what is causing line problems and equipment failure. Over the last four to five years, manufacturers have invested heavily in sophisticated technology such as HMI and SCADA packages to help them better visualize and control the manufacturing process. However, these systems are designed to be an operator interface to your control system, and often have limited data collection and storage capabilities.
Grinding disks are tools made of resin-bonded abrasive grains, reinforcing glass fabrics that give them mechanical strength and pores.
