, manufactured according to the specifications of the International Electrotechnical Commission (IEC), ensure global compatibility of machine components.Standards such as IEC 60034 secure compatibility, safety, and performance. Global companies like ABB utilize this uniformity. Why are global IEC standards indispensable?
IEC standards reduce inventory costs for spare motors, e.g., by over 10%.
Global interchangeability offers economic advantages beyond technical aspects, confirmed by logistical savings.The IEC 60034 series: The foundation of the standards
Die IEC 60034-Reihe: Das Fundament der Standards
IEC 60034-30-1 defined IE efficiency classes for globally uniform efficiency measurement. The standard is fundamental for comparison and promotion of energy-efficient motors.. Since 2014, motors (0.75–375 kW) must meet, e.g., IE2 (or IE3 with VSD).Mastering energy efficiency: navigating IE classes and regulations
From IE1 to IE5: A clear view of efficiency classes
An IE3 motor reduces energy losses compared to IE1 by up to 40%. IEC efficiency classes (IE1-IE5) provide guidance for IEC electric motors. IE3 has been mandatory since July 2021; IE4 will be required from July 2023 for certain power ranges. IE5 motors, such as the EC fan motor from Magnetic Innovations, offer the highest efficiency.
- Understand the IEC efficiency classes (IE1-IE5) as a guideline for energy-efficient motors.
- Benefit from significant energy savings (up to 40%) by using IE3 motors compared to IE1.
