Motors
- Purchase high efficiency replacement motors. Specify motors that meet NEMA Premium Efficient when purchasing new or replacement motors. Re-winding old in-efficient motors may not be cost-effective, compared to new highly efficient motors.
- Do not oversize motors Specify replacement motors sized to meet load requirements, as closely as possible. Oversized motors are inefficient.
- Use variable frequency drives (VFDs) where appropriate. Install VFDs on motors with variable load patterns, like pumps and fans.
- Check and maintain motors regularly. Check belts and pulleys frequently and tighten as needed. Lubricate motors regularly and replace bearings when worn.
