Full Description

Scope

Update IEEE 841-1994 based upon industry and manufacturer's experience since 1994. Maintain current scope of standard in include low and medium voltage TEFC motors with random - and form-wound coils in frame sizes 143T and larger.

Purpose

The revised standard will provide a specification that deals with mechanical and electrical design, electrical insulation systems, corrosion protection and electrical and mechanical testing for severe duty TEFC squirrel-cage, polyphase induction motors for petroleum and chemical industry applications. These applications require attention to the severely corrosive atmosphere and to the need for safe, quiet, reliable, energy-efficient motors.

Abstract

Revision Standard - Superseded.This standard applies to high-efficiency TEFC, horizontal and vertical, single-speed, squirrel cage polyphase induction motors up to and including 500 hp, in NEMA frame sizes 143T and larger, for petroleum, chemical, and other severe duty applications (commonly referred to as severe duty motors). Excluded from the scope of this standard are motors with sleeve bearings and additional specific features required for explosion-proof motors.
