⚠️ min mandatory IE efficiency requirements for ATEX motors

The EU Regulation (EU) 2019/1781 requires that also ATEX motors satisfy the min efficiency requested for all three phase motors

Despite many ATEX motors still circulating in Europe are offered with energy efficiency ratings as low as IE2 or even IE1, still considering the old exception stated by the Art. 1 of thereplaced EU Regulation 640/2009, the latest EU Regulation 2019/1781 mandates the following min efficiency for ALL motors, no matter if for safe area or ATEX:

  • Min IE2 only if <0,75kW
  • Min IE3 from 0,75 kW to 75 kW
  • Min IE4 >75 kW

From 2021 to 2023, an exception was made only for "Ex eb" ATEX motors like Motive’s. However, this exception was removed as of July 2023, and, anyway, Motive never cared about this exception. A surviving exception is instead the one of the motors for inverter power supply (i.e. not for direct in line)

Motive’s Delphi Ex motors have been ahead of the curve for years, meeting, since many years ago, not only the 2021 standards but also the stricter 2023 requirements. Also certified for use with frequency converters, our Delphi Ex motors have always available in the newly required min efficiency classes, ensuring compliance, durability, and superior performance.

What the Regulation Says

The Regulation (EU) 2019/1781 outlines the following (annex 1, point 1):

(a)

from 1 July 2021:

(i)

the energy efficiency of three-phase motors with a rated output equal to or above 0,75 kW and equal to or below 1 000 kW, with 2, 4, 6 or 8 poles, which are not Ex eb increased safety motors, shall correspond to at least the IE3 efficiency level set out in Table 2;

 

(ii)

the energy efficiency of three-phase motors with a rated output equal to or above 0,12 kW and below 0,75 kW, with 2, 4, 6 or 8 poles, which are not Ex eb increased safety motors, shall correspond to at least the IE2 efficiency level set out in Table 1;

(b)

from 1 July 2023:

(i)

the energy efficiency of Ex eb increased safety motors with a rated output equal to or above 0,12 kW and equal to or below 1 000 kW, with 2, 4, 6 or 8 poles, and single-phase motors with a rated output equal to or above 0,12 kW shall correspond to at least the IE2 efficiency level set out in Table 1;

 

(ii)

the energy efficiency of three-phase motors which are not brake motors, Ex eb increased safety motors, or other explosion-protected motors, with a rated output equal to or above 75 kW and equal to or below 200 kW, with 2, 4, or 6 poles, shall correspond to at least the IE4 efficiency level set out in Table 3.

Benefits Beyond Compliance

Investing in ATEX motors that meet the latest efficiency standards brings more than just legal compliance:

  • Lower Energy Bills: Higher efficiency reduces energy consumption, delivering significant savings.
  • Extended Motor Life: Reduced energy losses mean less heat generation, preserving the motor's winding and extending its lifespan.
  • Environmental Responsibility: Minimized energy usage reduces your carbon footprint and contributes to a greener future.

Choose Motive for Reliability and Performance

Delphi Ex motors combine cutting-edge efficiency with durability and adaptability. Whether for gas or dust explosive environments, they are the right choice to ensure safety, compliance, durability, and energy savings.
