Active Standard

IEEE 841.1-2023

IEEE Standard for Process Industry--International Energy Efficiency Class 3 (IE3) Premium-Efficiency, Severe Duty, Totally Enclosed Frame Surface Cooled Squirrel Cage Induction Motors--0.75 kW to 370 kW (1 hp to 500 hp)

International Energy Efficiency Class 3 (IE3) (premium-efficiency) totally enclosed fan cooled (TEFC) International Cooling IC411, totally enclosed air over (TEAO) IC418 and totally enclosed non-ventilated (TENV) IC410, horizontal and vertical, single-speed, squirrel cage polyphase induction motors, 0.75 kW to 370 kW (1 hp to 500 hp), and up to 4000 V, in International Electrotechnical Commission (IEC) frame sizes (80) and larger, for severe-duty applications seen in the Process Industry (commonly referred to as IE3 (premium-efficiency) severe-duty motors) are applied in this standard. Excluded from the scope of this standard are motors with sleeve bearings, totally enclosed blower-cooled (TEBC) IC416, and additional specific features required for flameproof motors.

Other Activities From This Working Group

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.


No Active Projects

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.


No Active Standards

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.


No Inactive-Reserved Standards
