The IEC Has Published the First Global Standard to Classify Energy Efficiency for High Voltage Induction Motors
March 11, 2024 The International Electrotechnical Commission (IEC) has published the first global standard to classify energy efficiency for high voltage (HV) AC induction motors operating on-line at up to 2000 kilowatt (kW). In common with the existing standard for low voltage (LV) motors, the new IEC/EN 60034-30-3 defines four efficiency classes ranging from IE1…
