Establish a Motor Management Program

• Survey all motors in facilities• Decide on motor disposition before failure and tag

each motor with action:– Replace immediately with Super-E motor– Replace on failure with Super-E motor– Replace on failure with Standard-E motor– Rewind on failure

• Reduce downtime - use replacement as an opportunity to upgrade motor enclosure and level of protection (replace with Severe Duty, IEEE 841 or Washdown motor)

Use of Baldor Energy Savings Tool

• BE$T program available on CD-ROM or download

• Allows easy analysis and payback of motor upgrade

• Figures 1 or more motors• Matches to equivalent Baldor

motor• Repair costs or rebates may be

used to quicken payback

Rebates from Utilities

• Many states and utilities offer significant rebates to upgrade to Super-E motors and adjustable speed drives

• Prescriptive rebates for certain applications• Custom rebates for large projects• US Department of Energy may have grant

money available for plant surveys (matching funds)

• Federal tax credits for commercial property upgrades

• Check with your electric utility, state energy organization or DOE for details
