Boosting Your Bottom Line: Optimizing Motor-Driven Systems Can Save Big

Your company can achieve signifi cant energy and bottom-line savings by implementing an effective motor management plan. With a welldefi ned, proactive plan in place, you are in position to optimize the benefi ts of NEMA Premium™ motors and best practice repair. But, the savings don’t stop there.

Examining and optimizing motors as part of an overall system can elevate benefi ts to the next level. Savvy facility managers realize that the savings and productivity gains that can be achieved by optimizing motor-driven systems can be greater than the combined savings of upgrading individual components.

Our July column highlighted the benefi ts of adjustable speed drives in appropriate applications. This was a fi rst step in looking at motors as part of a larger system. A logical next step might be to identify motor systems that are common to a variety of industrial processes and commercial applications, e.g. compressed air, pump and fan systems.

According to the Department of Energy (DOE), motor-driven systems account for 64% of the electricity consumed in the U.S. industrial sector. Furthermore, signifi cant reductions are possible through the use of proven equipment and technologies.

Compressed air systems, for example
Compressed air, a utility that is generated inhouse, serves a variety of applications. While a majority of industrial facilities have compressed air systems, few realize that compressed air generation accounts for a signifi cant portion of their facility’s energy consumption or that these systems can be notoriously ineffi cient—as low as 10-20%.

System optimization measures include identifying systems that are leaking or poorly confi gured for end use, and reducing system air pressure or running times. Both the Compressed Air Challenge Website and DOE’s BestPractices Website offer a wide array of resources to help facility managers understand and capture these benefi ts.

Optimization resources are available
The Department of Energy’s Website provides optimization resources for other motor-driven systems as well. These include sourcebooks, software tools, tip sheets, technical fact sheets, handbooks and even market assessments for the following areas: steam, process heating, motors, pumps and fans. The Environmental Protection Agency is yet another valuable resource. This agency’s Web site,, provides information and tools to help facility managers who are interested in generating energy and cost savings. (Tune in next month to learn more about the EPA’s energy management strategies for achieving continuous improvement and its benchmarking tools for commercial and industrial facilities.) The Motor Decisions MatterSM Web site provides links to additional optimization resources and information about funding sources for energy effi ciency across the U.S. and Canada. Visit, and click on Helpful Resources. MT

The Motor Decisions Matter campaign is managed by the Consortium for Energy Efficiency, a North American nonprofi t organization that promotes energy-saving products, equipment and technologies.
