New Ecodesign Regulation Increases Efficiency Requirements for Electric Motors
The EU's new Ecodesign Regulation (2019/1781) imposes stricter energy efficiency rules on industrial electric motors, effective from July 2021, with further tightening in July 2023.
Bargteheide, Germany – The European Union's new Ecodesign Regulation (EU) 2019/1781 has been raising the energy efficiency standards for three-phase electric motors since July 1, 2021. This regulation affects both standard and explosion-protected electric motors, with more stringent requirements set to take effect on July 1, 2023.
The initial phase mandates that three-phase asynchronous motors within the power range of 0.75 kW to 1,000 kW must meet IE3 energy efficiency class. Previously, this requirement applied only up to 375 kW. Additionally, 8-pole motors, which were previously exempt, are now included under these regulations.
For smaller three-phase motors (0.12 kW to 0.75 kW), the IE2 efficiency class is now required. The new rules also extend to explosion-protected electric motors with ignition protection types Ex tb, Ex tc, Ex ec, and Ex d. Earlier exemptions for brake motors, inverter-driven motors, and explosion-protected motors have been removed.
Further tightening of the regulations is scheduled for July 1, 2023. At that point, explosion-protected (Ex eb) three-phase asynchronous motors and single-phase motors ranging from 0.12 kW to 1,000 kW must comply with IE2 efficiency class. Furthermore, 2-, 4-, or 6-pole three-phase asynchronous motors with power ratings from 75 kW to 200 kW will be required to meet IE4 efficiency class. Brake motors and specific explosion-protected motors are noted as exceptions in this latter category.
