IEEE 841 IEEE Draft Standard for Petroleum and Chemical Industry--Premium-Efficiency, Severe-Duty, Totally Enclosed Squirrel Cage Induction Motor--0.75-370 kW (1-500 hp)
standard by IEEE,
Full Description
Scope
This standard applies to premium-efficiency totally enclosed fan cooled (TEFC) and totally enclosed non-ventilated (TENV), horizontal and vertical, single-speed, squirrel cage polyphase induction motors, 0.75-370 kW (1-500 hp), and up to 4160 V, in National Electrical Manufacturers Association (NEMA) frame sizes 143T and larger, for petroleum, chemical, and other severe-duty applications (commonly referred to as premium-efficiency severe-duty motors). Excluded from the scope of this standard are motors with sleeve bearings and additional specific features required for explosion-proof motors.Purpose
The purpose of this standard is to define a specification that deals with mechanical and electrical performance, electrical insulation systems, corrosion protection, and electrical and mechanical testing for severe-duty totally enclosed squirrel cage polyphase induction motors, 0.75-370 kW (1-500 hp), for petroleum, chemical, and other severe-duty application. Many of the specified materials and components in this standard stem from experience with severely corrosive atmospheres and the necessity for safe, quiet, reliable, premium efficiency motors.Abstract
Revision Standard - Superseded.
