Introduction to IEEE 841-2001, IEEE standard for petroleum and chemical industry-severe duty totally enclosed fan-cooled (TEFC) squirrel cage induction motors-up to and including 370 kW (500 HP)
IEEE 841-1994, IEEE Standard for petroleum and chemical industry severe duty totally enclosed fan-cooled (TEFC) squirrel-cage induction motors- up to and including 500 hp, issued in 1994, has been updated and improved. The scope includes three-phase severe duty TEFC squirrel-cage induction motors with antifriction bearings in sizes up to and including 370 kW (500 hp) and motor rated voltages of 200 V, 230 V, 460 V, 575 V, 2300 V and 4000 V at 60 Hertz. Changes to the standard are reviewed in detail. Requirements are identified that improve motor reliability and increase motor life.
