EISA Basics General Overview of Levels EISA (Public Law ) was signed by President Bush on December 19, 2007 and will become effective on December 19, Beginning on December 19, 2010, motor manufacturers may not build motors with a lower nameplate efficiency than EISA allows. EISA applies to both NEMA frame motors and the equivalent IEC frame motor. Motors that are built before December 19, 2010 but are held in inventory or are in transit can be sold, this deadline applies only to build dates.  General Purpose NEMA & IEC motors that today need to meet EPAct efficiency, will need to meet the NEMA Premium ® efficiency levels (Table 12-12) beginning on December 19, 2010  General Purpose NEMA & IEC motors that were exempt from EPAct because of voltage, mounting, etc. will need to meet EPAct efficiency (Table 12-11) beginning on December 19, 2010  NEMA & IEC motors that are not considered “General Purpose” (i.e., motors that cannot be used in most applications, such as special shafts, blowers or nonstandard frequencies, nonstandard volts/Hz) remain exempt from EISA regulations for efficiency.

Specific EISA Rules – Step 2 Step 2: Note: NEMA frames and IEC equivalents are included in the categories above, use features to determine efficiency If the motor does not have any features from the Standard Efficiency section on the previous slide and does not have any features from the EPACT section above, it must meet NEMA Premium (Table 12-12)

Motors that would need to meet NEMA Premium because they are otherwise General Purpose A spread voltage rating of v would require compliance to NEMA Premium (Table 12-12) at 230v and compliance with EPACT efficiency (Table 12-11) at 208v A spread voltage rating of /460v would require compliance to NEMA Premium (Table 12-12) at 230v and460v and compliance with EPACT efficiency (Table 12-11) at 208v If the design doesn't comply with the levels at 208 volt then, it would be acceptable to use "Operational at 208 volt at ## Max. Amps" on the blank line of the nameplate. Motors that would need to meet EPACT because of mounting or other features A spread voltage rating of v would require compliance to EPACT efficiency (Table 12-11) at both 208v and 230v A spread voltage rating of /460v would require compliance to EPACT efficiency (Table 12-11) at 208v, 230v and 460v. 208v, v, /460v

Examples of EISA Rules Example #1: Motor ABC is an EPACT motor (12-11) with rating 100hp 230/460v, 60Hz, 405T 1800rpm, TEFC, standard bracket, horizontal, rigid base. Beginning on December 19, 2010 it can no longer be sold because it is a General Purpose NE MA motor and will not meet the efficiency requirements under EISA. EISA requires that this model must meet NEMA Premium efficiency standards. Increasing the efficiency of this motor would require a design change. Example #2: Motor XYZ is the same as ABC except it has space heaters and a special 13.75” shaft extension. The special shaft extension makes motor XYZ exempt from the EISA requirements, therefore, it can continue to be purchased after December 19, 2010 without a design change or a substitute motor.

Higher efficiency motors: 1) Reduce the operating costs and less stress on utilities, supporting Green initiatives. 2) Generally operate at a lower temperature and for every 10°C reduction in operating temperature, insulation life doubles. 3) Are generally quieter (smaller fans). 4) Have lower vibration with lower bearing temperatures for longer bearing life. 5) Earn a rebate. Comparison of Operating Cost: Example: 100hp 1800rpm ODP motor Operating 24 hrs/day, 240 days/year at a cost of $0.08 per kW-hr Standard efficiency motor with 93% versus NEMA Premium motor with 95.4% Standard efficiency motor uses $36,963 worth of electricity per year to operate NEMA Premium motor uses $36,033 worth of electricity per year to operate In addition to direct energy cost savings, maintenance and downtime will be reduced. Why Should I Upgrade? Over a 20 year life this is $18,600
