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
  • IE2 is allowed to be used for variable speed drive

Turkey

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 from -30°C to +60°C
  • IE3 compulsory in DOL supply
  • IE2 is allowed to be used for variable speed drive

China

Scope:

  • Single-speed, 0.75 to 375 kW, (2, 4, 6 poles), 380 V 50 Hz or 50/60 Hz
  • Motor efficiency must meet the specified level at 100% load
  • Ambient temperature +40% or below
  • Continuous duty (S1) and S3 with a rated cyclic duration factor of 80% or higher
  • Applicable for all low voltage fan cooled (TEFC) motors including also Ex d, Ex de, Ex nA and Ex t motors
  • 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

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 USA has been at the forefront in requiring minimum efficiency levels for low voltage motors. The current regulation, 10 CFR (Code of Federal Regulations), was published in June 2016 replacing the previous regulation, Energy Independence and Security Act (EISA), and was signed into law in 2007, revised in 2010. Generally the regulation is called as Integral Horsepower Rule (IHP).
The Integral Horsepower Rule (IHP) builds on the previous Acts, updating the mandated efficiency standard for almost all three-phase 2-, 4-, 6- and 8-pole AC industrial motors from 1 to 500 HP (0.75 to 373 kW). Motors covered by the regulation must be verified and certified by a competent third party e.g. UL or CSA then registered to Department of Energy (DoE).
The IHP applies to both NEMA and IEC motors manufactured or imported for sales in the United States. In addition, all motors destined to US shall bear a safety certificate marking, such as CSAus or UL, indicating the compliance with UL standards.

  • 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
