EU MEPS - Commission Regulation (EU) 2019/1781 extends the scope of energy efficient motors covering the output range from 0.12 up 1000 kW.

Scope until June 30, 2021:

  • 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
  • IE2 is allowed to be used for variable speed drive

IE3 efficiency will be required starting July 1, 2021 for 3-phase motors::

  • Rated from 0.75 kW up to 1000 kW
  • Motors with protection types Ex ec, Ex d, Ex de or Ex t
  • Motors with IC418 cooling method (TEAO)
  • Brake motors with external brake

IE2 efficiency level will be mandatory for motors with rated ouput from 0.12 to 0.75 kW, which are not Ex eb.

Australia

New Greenhouse and Energy Minimum Standards Determination 2018 is implemented on 14th May 2019 and onwards. Both Minimum efficiency (IE2) and High efficiency (IE3) levels will remain but are aligned with levels in IEC 60034-30-1 Ed.1.0.

Scope is identical for the compulsory Minimum efficiency and the volutary High efficiency:

  • Single-speed, 0.75 up to but not including 185 kW
  • Voltage up to 1100 V
  • 2, 4, 6, 8 poles
  • Safe area motors and motors for explosive atmospheres
  • Inverter duty motors that can be operated DOL
  • Motor efficiency must meet the specified level in AS/NZ 1359:5:2004 either at 100% or 75% load

US
The current regulation, 10 CFR 431, Subpart B (Code of Federal Regulations), also called as Integral Horsepower Rule (IHP). It is almost identical with the Energy Efficiency Regulations in Canada. The nominal energy efficiencies as defined in the Regulation are identical with the NEMA MG-1:2014 Table 12-12 as well as with IE3 levels according to the standard IEC 60034-1.

Motors covered by the regulation must have the energy efficiency verification file (EEV) hence verified and certified by a competent third party e.g. UL or CSA and finally registered to the Department of Energy (DoE).

In addition, all motors destined to US shall bear a safety certificate marking, such as ULus, or cULur or CSAus, cCSAUs indicating the compliance with the relevant UL standards.

Scope:

  • three-phase induction, single speed motors including explosive atmosphere and TENV motors
  • nominal power from 0.75 kW (1 horsepower) to 375 kW (500 horsepower)
  • rated for continuous duty or S1 operation
  • nominal voltage not more than 600 V AC, 60 Hz
  • 2, 4, 6, 8 poles
Canada

The Energy Efficiency Regulations, 2016 was published, along with the a Regulatory Impact Analysis Statement that came into force on June 28, 2017. The regulation is almost identical with the Regulation 10 CFR 431, Subpart B in the US. The nominal energy efficiencies, as defined in the standard CSA C-390-10, are identical with the 10 CFR 431, Subpart 014 Tale 12-12 and IE3 levels according to the standard IEC 60034-1 but the scope is slightly different.

Motors covered by the regulation must have the energy efficiency verification file (EEV) hence verified and certified by a competent third party e.g. CSA or UL and finally registered to the Natural Resources Canada (NRCan).

In addition, all motors destined to Canada shall bear a safety certificate marking, such as ULus, or CULus or CSAus, cCSAus or CUlus, indicating the compliance with the relevant CSA standards.

Scope:

  • three-phase induction, single speed motors including explosive atmosphere motors
  • nominal power 0.75 (1 horsepower) to 375 kW (500 horsepower)
  • rated for continuous duty or S1 operation
  • nominal voltage not more than 600 V AC, 50 Hz, 50/60 Hz or 60 Hz
  • 2, 4, 6, 8 poles
Brazil

Brazilian MEPS is based on the standard ABNT NBR 17094-1:2013 that defines IR energy efficiency limits and IR3 being the minimum allowed efficiency level. ABNT NBR 17093-1:2013 has some differences with the standard IEC 60034-1.

Motors must be registered to the INMETRO and the energy efficiency is annually tested by the test laboratory authorized by INMETRO.

Scope:

  • three-phase squirrel cage induction motors including also non-sparking (Ex nA) motors
  • nominal power from 0.12 to 370 kW
  • 2, 4, 6, 8 poles
  • Voltage up to 1000 V, 50 Hz or 60 Hz, for operation at 60 Hz

  • 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
