Energy efficiency

By making the decision to use energy efficient motors, you can lower your energy costs and have a positive effect on the environment. ABB’s energy efficient motors are designed and labeled to comply with the international IEC standards. In addition, motors are naturally supplied to conform to local Minimum energy performance standards (MEPS) where applicable. Learn more about efficiency and energy savings from this page.

EU MEPS (European Minimum Energy Performance Standard) sets mandatory minimum efficiency levels for electric motors introduced into the European markets.

Scope:

  • Single-speed, 0.75 to 375 kW, 2 to 6 poles, up to 1000 V, 50 Hz, motors rated on the basis of continuous duty operation
  • Ambient temperatures between -30 °C and +60 °C
  • IE3 compulsory in DOL supply in the power range of 0.75 kW to 375 kW
  • IE2 is allowed to be used for variable speed drive use in the power range of 0.75 kW to 375 kW.

Turkey has confirmed the EU MEPS efficiency requirements as legal requirements following the same timeline. 

Scope:
  • Single-speed, 0.75 to 375 kW, 2 to 6 poles, up to 1000 V, 50 Hz, motors rated on the basis of continuous duty operation
  • Ambient temperatures between -30 °C and +60 °C
  • IE3 compulsory in DOL supply in the power range of 0.75 to 375 kW
  • IE2 is allowed to be used for variable speed drive use in the power range of 0.75 to 375 kW.
Scope:

  • Single-speed, 0.01 to 375 kW, 2 to 6 poles, 50 Hz or 50/60 Hz
  • Motor efficiency must meet the specified level at 100% load, 380 V 50 Hz
  • Ambient temperature +40°C or below
  • Continuous duty (S1) and S3 with a rated cyclic duration factor of 80% or higher
  • Applicable for all low voltage motors including also motors for explosive atmospheres - flameproof, non-sparking and dust ignition protection
  • Three different efficiency levels are specified by GB18163-2012, IE2 being the minimum 
  • IE3 efficiency level implementation is not available      
  • Note: additionally CNEx certification required for motors for explosive atmospheres

Scope is identical for the compulsory MEPS and for the voluntary HE MEPS::

  • Single-speed, 0.73 up to - but not including - 185 kW
  • Voltage up to 1100 V
  • 2 to 8 poles
  • Safe area motors, motors for explosive atmospheres
  • Inverter duty motors that can be operated DOL
  • Motor efficiency must meet the specified level in AS/NZS 1359:5:2004 either at 100% or 75% load. Minimum efficiency level roughly equal to IE2, in some cases higher.

The USA has been at the forefront in requiring minimum efficiency levels for low voltage motors. The current Energy Independence and Security Act (EISA) was signed into law on December 19, 2007, revised in 2010 and replaced by the Integral Horsepower Final Rule (10 CFR Part 431), issued by the Department of Energy (DoE) in June 2016.

The Integral Horsepower Rule (IHP) builds on the previous Acts, updating the mandated efficiency standard for almost all three-phase AC industrial motors from 1 to 500 HP (0.75 to 373 kW).

The Integral Horsepower Rule (IHP) applies to both NEMA and IEC motors manufactured or imported for sale in the United States.

ABB offers full range of NEMA motors under Baldor brand and a broad range of IEC motors. 

Federal Regulations in Canada are effective since 1997 and were revised 1999 and 2012. The 2012 revised efficiency legislation was similar to EISA 2007 and will be replaced on June 28 2017 by the new Energy Efficiency Regulations (EER). The new EER will be almost identical with the Integral Horsepower Rule (IHP) having some small deviations e.g. IEC frame size 80 is also included in the EER. Motors subject to EER must be certified and registered to Natural Resources of Canada (NRCan). In addition, all motors destined to Canada must bear a safety certificate marking, such as CSA or cUL.

ABB offers a full range of NEMA motors under Baldor brand, and a broad range of ABB IEC motors in cast iron frames.

Scope:

  • IE2 (standard efficiency) from 0.75 to 30 kW, 2 to 8 poles
  • IE3 (premium efficiency) from 37 to 200 kW, 2 to 8 poles
  • IE3 (premium efficiency) from 200 to 375 kW, 4 to 8 poles
  • Voltage up to 600 V, 60 Hz
  • Continuous duty S1
  • Applicable for 3-phase DOL motors including motors for explosive atmospheres
  • VSD motors driving fans, pumps and blowers
  • Ambient temperature +40°C and below
  • Altitude max 1000 m above sea level
  • Torque design A and B
  • Brake and gear motors
  • IE3 (premium efficiency) will be compulsory for output powers from 0.75 to 37 kW, 2 to 8 poles, from October 1, 2018.

Brazilian MEPS is based on ABNT NBR 17094-1:2013 standard, all motors must be dimensioned with service factor 1.15.

Scope:

  • 0.75 to 185 kW, 2 to 4 pole
  • 0.75 to 150 kW, 6 pole
  • 0.75 to 110 kW, 8 pole
  • Voltage up to 1000 V, 50 Hz or 60 Hz, for operation at 60 Hz
  • One or more speeds, for operation at one unique speed
  • Continuous operation S1 or S3 (≥80%) acc. to NBR 17094-1:2013
  • Categories N, H, NY and HY acc to NBR 17094-1:2013
  • Totally enclosed and fan cooled (forced or shaft mounted)
  • Open or closed type motors
  • Safe area and non-sparking motors
  • Minimum efficiency level IR2 roughly equal to IE2, IR3 roughly equal to IE3.

According to SASO IEC 60034-30:2013 following motors are included in the SASO efficiency regulation and registration is required:

  • Stand-alone
  • Single-speed, three phase
  • 0.75 to 375 kW, 2 to 6 pole
  • Voltage up to 1000 V, 60 Hz or 50/60 Hz
  • Continuous duty S1 or intermittent duty S3 with cyclic duration factor 80% or higher
  • Operating direct on-line (DOL)
  • Altitude less than 1000 m above sea level
  • Ambient temperature from -15°C to +40°C
  • Minimum efficiency level
