NEMA Premium Efficiency Motors Program

Getting Prepared for the $700 Million NEMA Premium Efficiency Motor Rebate Program

Reading Electric is a leading supplier of Electro-Mechanical Equipment and Services for industrial and commercial customers. For over 50 years, we continue to be the region’s problem solvers for the commercial and industrial community. This Bulletin is the first in a Technical Information Series providing information on the NEMA Premium Efficiency Motors Program and proposed Rebate Program.

NEMA Premium Efficiency Motor Rebate ProgramThe member companies of the NEMA Motor and Generator Section established a NEMA Premium® energy efficiency motors program to provide highly energy efficient products that meet the needs and applications of users and original equipment manufacturers (OEMs) based on a consensus definition of “premium efficiency”. NEMA Premium® labeled electric motors will assist purchasers to optimize motor systems efficiency, reduce electrical power consumption and costs, and improve system reliability.

Why should you prepare for the Rebate Program?

The Energy Independence & Securities Act (EISA) was signed into law on December 19, 2007 and will be enforced beginning on December 19, 2010. After December 19, 2010 motor manufacturers may not build motors that have a lower nameplate efficiency than the EISA rules allow.

General Overview of Levels for NEMA Premium Efficiency

  • NEMA Premium Efficiency Motor Efficiency Levels OverviewGeneral Purpose motors that today need to meet EPACT, will need to meet the NEMA Premium efficiency levels in 2010.
  • General Purpose motors that were exempt from EPACT because of voltage, mounting, etc will need to meet EPACT in 2010.
  • Motors that cannot be used in most applications, such as special shafts, blowers or nonstandard frequencies, are exempt from any regulations for efficiency.

What does “efficiency” mean?

Efficiency is a measure of how much total energy a motor uses in relation to the rated power delivered to the shaft. A motor’s nameplate rating is based on output horsepower, which is fixed for continuous operation at full load. There are several ways to express motor efficiency, but the basic concept and the numerical results are the same. For example:

Efficiency, % = 746 x Horsepower (output) x 100 Watts (input)
Efficiency, % = Watts (output) x 100 Watts (input)

Next Month’s Tech Bulletin will focus on the proposed $350 Million Rebate Program to assist User’s in purchasing NEMA Premium Efficiency Motors.
