Product catalog summary
Introduction
This document provides an overview of the specifications, efficiency classifications, and regulatory requirements for electric motors, focusing on the IEC 60034-30 standard and the European ecodesign directive.
Specifications and Exclusions
Motors suitable for ambient conditions as per IEC 60034-1 are included, while those designed for inverter operation or integrated into other machines are excluded. Non-standard mechanical dimensions, gear, brake, and explosion-protected motors are included.
Efficiency Classification
Efficiency classes under IEC 60034-30 include IE1 (Standard), IE2 (High), IE3 (Premium), and IE4 (Super-Premium). These classifications are crucial for reducing CO2 emissions and energy costs.
Regulatory Framework
The European ecodesign directive 2009/125/EC sets minimum efficiency performance standards (MEPS) for electric motors. Key implementation steps include:
  • IE2 minimum efficiency from June 16, 2011
  • IE3 for 7.5 kW to 375 kW motors from January 1, 2015
  • Extension to 0.75 kW to 375 kW range from January 1, 2017
Exceptions include motors for specific ambient conditions and those integrated into other machines.
Market Implications
Post-June 2011, IE1 motors are not allowed in the market, with a shift towards IE2 and IE3 motors. The document advises reducing stock of EFF2/IE1 motors and transitioning to energy-saving motors.
Energy-Saving Solutions
Combining IE2 motors with frequency converters enhances efficiency across various load ranges, beneficial for applications like pumps, fans, and conveyor engineering.
Conclusion
The document encourages adopting energy-efficient motors to meet environmental challenges and reduce energy costs. Contact information is provided for further assistance and product details.
Overview
VEM has updated its product range to meet new efficiency limits, offering motors across all efficiency classes to reduce CO2 emissions and energy costs. Customers are encouraged to contact VEM's Competence Center in Germany or its sales partners for advice on energy-efficient solutions.
Regulations and Standards
The document references Regulation (EC) no. 640/2009, setting minimum efficiencies for three-phase asynchronous motors, and mentions the IEC 60034-30: 2008 standard.

News on energy efficiency-2

Efficiency classification and determination of efficiencies In the last few years the world-wide development for energy saving motors has led to a multitude of country related regulations, laws and standards. This has made it difficult to compare and evaluate the individual products. To create a uniform world-wide base, the new IEC standard 60034-30 has been issued. This standard replaces the former Voluntary Agreement of CEMEP and at the same time extends the former scope to 2-, 4- and 6-poles and a power range of 0.75 to 375 kW. The marking is done corresponding with the code for type of protection...
