The new legislation has prompted a wide range of important questions.  The Motor Specialist was created to help answer these questions and help to make it easy for you to find the important answers that you need.  

EISA Legislation Questions

  • What is EISA?
    • The Energy Independence Security Act of 2007 (EISA) was passed to create, among many other things, higher energy efficiency standards for general purpose and other industrial motors.  Learn more about the act in the EISA Overview
  • When does EISA take effect?
    • December 19, 2010.
  • What are NEMA Premium Efficiency Motors?
    • Products must meet or exceed the nominal energy efficiency levels presented in NEMA Standards Publications MG 1- 2006, in Tables 12-12 and 12-13, respectively. 
    • What are the current efficiency nomenclatures?
    • Standard Efficiency:  Not defined
    • High Efficiency:  Not defined
    • EPAct Efficiency:  NEMA MG1 Table 12-11
    • Premium Efficiency  Not Defined
    • NEMA Premium Efficiency:  NEMA MG1 Table 12-12 (LVAC) and 12-13 (MVAC)
    • EISA Compliant:  EISA references all three NEMA MG1 Tables (12-11, 12-12, 12-13), depending on the product description


  • How do I know if my motor is EISA compliant?
    • EISA legislation affects a wide range of general-purpose motors.  Learn about the specifications in the EISA Overview.
  • Are pump motors, such as Close Coupled and Footless Motors, affected by EISA? 
    • Close Coupled and Footless Motors now fall under Subtype II regulations and must meet acceptable efficiency levels and include a Certificate of Compliance.
  • Are IEC frame motors subject to EISA?
    • Yes, all IEC metric frame motors, 90 frame and up are subject to EISA legislation (excluding 100 frame).
  • Are Fire Pump motors subject to EISA?
    • Yes.  Fire Pump motors now fall under Subtype II motors and are subject to EPAact 12-1 regulation.
  • Are Hazardous Location (XP) motors subject to EISA? 
    • Yes, Hazardous Location (XP) motors were regulated by EPAct and must now meet NEMA Premium Efficiency standards.
  • What motors are exempt?
    • Single Phase Motors
    • DC Motors
    • 48 or 56 frame motors
    • Fractional Hp motors
    • Totally enclosed non-ventilated and totally enclosed air-over motors
    • Design D motors with high slip
    • Motors with voltages exceeding 600V
    • Inverter duty motors with windings optimized for adjustable speed drive
    • Customized OEM mounted motors
    • Intermittent duty motors
    • Integral gear motors or brake motor designs
    • Submersible motors
  • Are Inverter Duty Motors Subject to EISA?
    • Inverter duty motors must meet EISA efficiency requirements if the inverter motor can be used for general purpose applications.  Inverter duty motors designed with special volts/Hertz requirements are exempt.
  • What if I manufacture my own motor for my own equipment?
    • OEMs must submit a Compliance Certificate (CC#) Application to the Department of Energy to verify motor compliance.  This submission for 3rd party certification must include motor test results from accredited labs or programs demonstrating that the existing motor design meets the requirements of the intended application.

Replacement Questions

  • If my motor isn't EISA-compliant, do I have to replace it now?
    • EISA does not require that non-compliant motors be put out of service, only that most new general purpose 1-200 hp motors produced and sold in the US must meet NEMA Premium Efficiency standards.   
  • What are the benefits of upgrading?
    • Immediate efficiency improvements, long-term energy savings, part availability, faster payback.
  • Do new Premium Efficiency motors require system retrofits?
    • While new motors are sometimes larger due to the materials used in construction, most are scalable and few require retrofits.
  • Can I repair my motor even if it's non-EISA compliant?


  • How much will it cost to upgrade?
    • NEMA Premium Efficiency motors generally have a higher initial purchase price (15 - 30% more than EPAct or standard efficiency motors).  However, the energy cost savings can generate a ROI usually in 6-12 months.  Use our Energy Cost Savings Calculator to calculate your savings.   
  • Are rebates available?
    • Yes.  State and local utility rebates are available.  Legislation has been introduced in Congress for a federal rebate program, but federal rebates are not currently available.  Visit the Rebate Center for more information.
  • What makes a NEMA Premium Motor more efficient?
    • The use of higher grades of electrical-grade steel, aluminum, more copper, permanent magnets and increased communication between motors and drives.  Exotic magnets are able to produce higher torque in smaller packages.
  • Can Motion Industries help me develop a Motor Managment Plan for my facility?
    • Yes, The Motor Specialist can help you develop a plan to optimize your motors and make planned replacements.   Contact Motion Industries today to begin developing your Motor Management Plan.
