INTERNATIONAL EFFICIENCY LEVELS - IE CODE 

 

The International Standard IEC 60034-30-1;2014 ensures an international common base for electric motor designing and classification, as well as for national legislative activities, increasing the level of harmonization in MEPS (Minimum Energy Performance Standard) all over the world.


The IEC 60034-30-1 states the efficiency levels (IE codes) and requirements, provides test conditions and efficiency measurement methods specified in IEC 60034-2-1;2014. It doesn’t state the motors to be supplied or the minimum efficiency level (MEPS).

 

This depends on any national legislative activities and government targets to save energy and reduce environmental impact. The efficiency levels provided by the standard for single speed and three-phase motors – brake included - 50 Hz or 50/60 Hz, with rated output 0.75kW to 375kW, 2, 4 or 6 poles, on the basis of continuous duty operation S1 or intermittent periodic duty operation S3 are the following: 

IE1 = Standard Efficiency 

IE2 = High Efficiency 

IE3 = Premium Efficiency

Standard specifications

EU – COMMISSION REGULATION EC 4/2014
The Commission Regulation EC 4/2014 specifies efficiency requirements for three-phase AC motors from 0.75 to 375kW, 2, 4 and 6 poles, and introduces in all countries of the European Community the following MEPS from 1st January 2017:

- motors from 0.75 to 375kW -  IE3 minimum efficiency or IE2 only for motors with variable speed drive (VSD) and marked with specific label.

Motors to be exclusively exported out of the EEA (machine distributors or manufacturers) may be produced and distributed with IE1 and IE2 efficiency level even after relevant deadline. To that end, a statement will have to be made to the manufacturer.

 

USA – EISA 2007

The Energy Independence and Security Act of 2007 (EISA) was signed into law on Dec 2007 and enforced in Dec 2010 (last revision in 2014). EISA replaces the previous EPAct (Energy Policy Act 1992) approved by the U.S. Congress in 1992, and sets Nema Super Premium Efficiency IE3 as minimum level for general purpose, three-phase AC industrial motors from 1 to 500HP which are manufactured or imported for sale in USA.

The U.S. Department of Energy (DOE) is responsible for establishing the rules to implement. The rating plate must be market with the motor’s nominal full load efficiency (NEMA nominal efficiency) and the manufacturer’s CC-number (compliance certificate number).

 

CANADA - ENERGY EFFICIENCY ACT

Canada has had minimum energy performance standards in place since 1995. These standards were amended in 1997 to include Explosion Proof Motors and Integral Gear Assembly Motors.

The regulation regarding electric motors was progressively revised and, as of June 2016, has a more stringent scope; the minimum efficiency level is IE3.

The rating plate must show NEMA nominal efficiency at 100% load and the safety certificate marking, such us CSA.

 

AUSTRALIA – MEPS SCHEME

The Australian MEPS Scheme was announced in 2001 by the Australian Greenhouse Office (AGO), and was revised in 2006. All motors covered by the scheme that will be sold in the Australian and New Zealand markets must be registered in a National online database system, www.energyrating.gov.au/appsearch/motors.asp.

Standards AS/NZS 1359,5:2004 stipulates two efficiency levels: the compulsory minimum efficiency level IE2 or better, and a voluntary high efficiency level IE3 or better. The scheme is monitored by a regulatory body which conducts random testing to ensure compliance. Importing unregistered motors is subject to strict penalties.

 

BRAZIL – PBE LABELING PROGRAM

The PBE Brazilian Labeling Program has been in force since December 2009 and is overseen by INMETRO. From 2012 the minimum efficiency level is IE2. All motors covered by NBR standards must be provided with specific rating plate marking and additional stickers depending on a degree of protection.All motors must be registered on the INMETRO, website at www.inmetro.gov.br.

 

CHINA – ENERGY LABEL SCHEME

The China Energy Label Scheme has been mandatory since 01.09.2008 and was revised in 2012. From 01.09.2016 motors must meet Grade 2 (IE3) requirements. China has taken a major step towards harmonizing its national standards with IEC standards.

Standard GB/T1032 defining the efficiency measuring method, has been updated and brought in line with IEC 60034-2-1 and the grades are in line with efficiency classes defined in IEC 60034-30-1. In addition to energy efficiency requirements, low power motors are subject to CCC certification.

 

KOREA – MEPS SCHEME

The Korean MEPS Scheme was introduced on 01.07.2008 by the Ministry of Commerce, Industry and Energy (MOCIE) and implemented in three steps. Certification is granted by the Korea Energy Management Corporation (KEMCO).

Korean MEPS is identical to IE3 (60HZ). A specific sticker is required and all motors must be registered with the authorities. Motors that do not have the MEPS sticker will not be allowed into Korea.

 

REST OF THE WORLD
Many Countries are recognizing the importance of Energy Efficiency in electric motors and its potential economic and environmental impact and are working on developing mandatory minimum energy performance standards to be implemented in the near future.These standards are expected to follow the IEC60034-30-1 classification.
