Recent new IEC standards and guides on electric motors

By Electric Motor Systems ·

The International Electrotechnical Commission IEC has recently issued several new Standards and Guides on electric motor energy efficiency:

 

  • IEC 60034-1 (Edition 12: 2008/CD): Rating and performance
  • IEC 60034-2-1 (Edition 1.0:2007): Standard methods for determining losses and efficiency from tests
  • IEC 60034-2-3 (2008/WD): Specific test methods for determining losses and efficiency of converter-fed AC machines
  • IEC 60034-30 (Edition 1.0: 2008): Efficiency classes of single-speed, three-phase, cage-induction motors (IE-code)
  • IEC 60034-31 (2008/CD): Guide for the selection and application of energy-efficient motors including variable-speed applications
  • IEC TC2/WG28: Round-robin on electric motors (download: Intermediary Report: June 2008)
