#MotorTalkMonday – What’s new for the IEEE 841-2021 standard?
The Institute of Electrical and Electronic Engineers (IEEE) developed the IEEE 841 motor standard in 1986 for the petroleum and chemical industries to improve the reliability, efficiency and performance of severe duty motors. The conditions and applications in these environments place high levels of mechanical stress on electric motors, and environmental contaminants such as dust, dirt and liquids can cause premature, catastrophic, failure to regular duty motors.
In short, IEEE 841 motors are designed for severe duty applications in the most demanding industries. The IEEE 841 standard covers the construction of the motor, and specifically “premium-efficiency totally enclosed fan-cooled (TEFC) and totally enclosed nonventilated (TENV), horizontal and vertical, single-speed, squirrel cage polyphase induction motors, 0.75 kW to 370 kW (1 hp to 500 hp), and up to 4000 V nominal, in National Electrical Manufacturers Association (NEMA) frame sizes 143T.”
