IEEE - P841.1/D1

Draft Standard for Petroleum and Chemical Industry IE3 (Premium Efficiency), Severe-Duty, Totally Enclosed (IC411, IC410) Squirrel Cage Induction Motors-0.75-370 kW (1-500 hp)

pending, Most Current
Organization: IEEE
Publication Date: 1 October 2019
Status: pending
Page Count: 35
scope:

This standard applies to IE3 (premium-efficiency) totally enclosed fan cooled IC411 (TEFC) and totally enclosed non-ventilated IC410 (TENV), horizontal and vertical, single-speed, squirrel cage polyphase induction motors, 0.75-370 kW (1-500 hp), and up to 4000 V in International Electrotechnical Commission (IEC) frame sizes (80) and larger, for petroleum, chemical, and other severe-duty applications [commonly referred to as IE3 (premium-efficiency) severe-duty motors]. Excluded from the scope of this standard are motors with sleeve bearing and additional specific features required for flame proof motors.

Purpose

The purpose of this standard is to define a specification that deals with mechanical and electrical performance, electrical insulation system, corrosion protection, and electrical and mechanical testing for severe-duty totally enclosed squirrel cage poly-phase induction motors, 0.75-370 kW (1-500 hp), for petroleum, chemical, and other sever-duty applications (commonly referred to as IE3 (premium-efficiency) severe-duty motors). Many of the specified materials and components in this standard stem from experience with severely corrosive atmospheres and the necessity for safe, quite, reliable, IE3 (premium efficiency) motors.
