Standards & regulations

IEC 60034-30-1 ed 1.0 published
The new standard IEC 60034-30-1 with efficiency classes of line operated AC motors was published on 6 March 2014. This IE-code now includes IE4 Super Premium Efficiency motors and 8-pole motors in the output range from 0.12 kW up to 1000 kW in 50 Hz and 60 Hz. It supersedes the 2008 edition of IEC 60034-30, now withdrawn. It soon will be followed by IEC 60034-30-2 with efficiency classes for motors rated for variable frequency supply.

Buy IEC 60034-30-1 in English/French, hardcopy or pdf:

IEC/TS 60034-2-3 ed 1.0 published
The technical specification IEC 60034-2-3 "Specific test methods for determining losses and efficiency of converter-fed AC induction motors" was published in November 2013. It explains the concept of the reference converter for the measurements of the additional harmonic losses in the motor.
Buy the standard.

The revision of the test standard IEC 60034-2-1 is nearing completion
The Final draft international standard IEC 60034-2-1 is open for editorial comments until 2 May 2014 and will be published soon after that. For 3-phase machines with rated output power up to 2 MW it defines the Method 2-1-1B: Summation of separate losses. Additional load loss determined by the method of residual loss. If you want to review the draft please write to your national IEC committee.

Loophole closed: amending Ecodesign Regulation no 640/2009
The European Commission closed the loopholes for motors that were considered by some manufacturers outside of the scope of regulation no 640. The new Regulation No 4/2014 of 6 January 2014, is formally amending the existing Regulation (EC) No 640/2009: Article 1, and establishes ecodesign requirements for electric motors, except for motors specified to operate exclusively:

  • at altitudes exceeding 4 000 metres above sea-level;
  • where ambient air temperatures exceed 60°C;
  • in maximum operating temperature above 400°C;
  • where ambient air temperatures are less than -30°C for any motor or less than 0°C for a motor with water cooling;
  • where the water coolant temperature at the inlet to a product is less than 0°C or exceeding 32°C;
  • in potentially explosive atmospheres.

Regulation updates from the USA
The Department of Energy published:
  • a Notice of Proposed Rulemaking for energy conservation standards for electric motors on 6 December 2013, to extend the scope of currently covered motors.
  • a final rule regarding test procedures for electric motors to enable testing of all motors to be covered, on 13 December 2013.
  • Framework documents are available regarding energy conservation standards for commercial and industrial air compressors, fans and blowers and pumps.
A summary on all rulemakings

New standards in China
The follwoing new standards were published in China on 18 December 2013, taking effect from 1 September 2014:

  • GB 30254-2013 "Minimum allowable values of energy efficiency and the energy efficiency grades for cage three-phase high voltage induction motor"
  • GB 30253-2013 "Minimum allowable values of energy efficiency and energy efficiency grades for permanent magnet synchronous motors"

Only when you look at the entire Motor System you are ready for big energy savings!

EMSA proposes a clear and universal definition of motor systems and their key componets on the electrical and mechanical side. The largest energy savings are always achieved when the entire motor system is optimized. For regulators, the reference is the MOTOR DRIVEN UNIT that includes motor, VFD and application. For the next generation of IEC standards the task is to match the motor with the VFD as planned in IEC 61800-9.

If you want to know more about definitions of Motor Systems and Motor Driven Units go to EMSA insights no 1.

Motor Systems Tool version 2.13.20
A new version of the Motor Systems Tool is now available, including:

  • updated motor, variable speed drive and gear models
  • new model for permanent magnet motors
  • user-defined load, either as single duty point or complete load profile.

SEAD Global Efficiency Medal Competition for Electric Motors
Manufacturers of efficient electric motors have nominated their best-performing products for the SEAD Global Efficiency Medal Competition for Electric Motors.
This global competition helps identify the world’s most efficient products. It will recognize the top-performing IEC and NEMA induction motors in various size categories and new technology motors with the greatest potential to reduce energy consumption. SEAD will recognize four regional winners as well as overall global winners for each motor category. Currently, the claimed efficiencies of the nominated motors are being tested at Advanced Energy testing lab in Raleigh North Carolina, USA. Winners will be highlighted at the Motor Summit 2014 in Zurich.

IHS market report upcoming
IHS has started research for its 2014 Low Voltage Motors study, which will be published in August. It will also be doing a dedicated report on IE4 motors to provide more visibility into this growing segment of the market. For more information please contact IHS analyst Mark Meza at mark.meza@ihs.com.

EMSA Operating Agent & Coordinator

EMSA is the Electric Motor Systems Annex of the International Energy Agency's Implementing Agreement on Energy Efficient End-use Equipment 4E. Currently Australia, Austria, Denmark, Netherlands, USA and Switzerland participate actively in EMSA. Canada, France, Japan, Korea, Sweden and United Kingdom participate in other 4E Annexes.
The second EMSA program phase is running until 2014.
