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)

IEEE 841 IEEE Проект стандарта для нефтяной и химической промышленности - премиум-эффективности, Severe-Duty, полностью закрытый с короткозамкнутым ротором асинхронный двигатель - 0.75-370 кВт (1-500 л.с.)

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.
