1. May 22, 2007 Quality Motor Rewinding an Energy Efficiency Measure Regional Technical Forum Submittal

2. In today’s energy climate motor service centers and their influence should not be overlooked In 1994, electric motor driven systems used 679 billion kWh or 23% of all electricity sold in the U.S.

3. Many energy efficient motors are reaching the end of their life and will need repair It is time to address this issue

4. Without attention to controlled motor repair protocol expect efficiency losses of: 1% if the motor is 40 HP or smaller;.05% if 50 HP or greater. With Green Motors protocol expect no efficiency losses

5. Documents efficiency unchanged even after five rewinds Requires a controlled process; A failure event does NOT affect the motor core. BUT

6. NEMA Premium® 5HP, 4 Pole, 3Ø, 89.5% Efficient Motor 100% Power89.5% Out Stator Res. Rotor Res. Iron Core Friction/ Windage Stray Losses Total 100% 10.5% 5%.05%1.1% 10% 20% 2.1%2.6% 25% 4.2% 40% Percent of Input Percent of Losses New Motor losses—what can rewinding affect?

7. Green Motors Service Centers sign a commitment to: Retain efficiency in the repair/rewind process; Base recommendations on total cost of ownership; Train personnel, allow GMPG inspection and review; Advise customers of catastrophic failures; Non-compliant service centers are removed.

Resources Green Motors Practices Group The Industrial Efficiency Alliance (NEEA) Activities RTF Recognizes Green Motors Practices Energy Savings Utility Service Center Program Outline is Developed by the IEA Outputs Utilities offer Incentives for Quality Motor Rewinding Efficiency is a Core Business Value of Green Motor Practices Members Outcomes Motor Market Leaders not only Offer Motor but Systems Efficiency Assistance An Army of Efficiency Allies is Established Impact Efficiencies are Sustained and Systems are Optimized Saving kWhs Total Cost of Ownership and Quality are the Norm Green Motors Practices Logic Model

12. Sample Incentive Application (Runtime database) Unique identifier (also appears on motor) Consumer information Quantifiable savings data Test results report reinforces protocol Third party oversight

13. Retains efficiency; Is cost effective; Reaches even custom made motors; Will lead to uniform utility programs; Bolsters the bottom-line of commercial, agricultural, and the industrial community; Is virtually “plug-and-play” and; Is an energy efficiency measure The Green Motors Practices Group :
