IEEE 841 Premium Motors
IEEE 841 Premium Motors are electric motors that are designed to meet specific performance and durability standards set forth by the Institute of Electrical and Electronics Engineers (IEEE). These motors are used in a variety of industrial applications where reliable and efficient performance is critical. IEEE 841 Premium Motors are used in harsh or extreme environments that may be subject to moisture, dust, corrosive chemicals, high or low temperatures, or other environmental factors that can affect the performance and lifespan of a motor. These environments include oil refineries, chemical processing plants, paper mills, water treatment facilities, and other heavy industrial settings. IEEE 841 Premium Motors are built to withstand these harsh conditions and are designed to provide superior performance, energy efficiency, and reliability. They typically have features such as rugged cast iron frames, corrosion-resistant coatings, and heavy-duty bearings, which make them well-suited for these challenging applications.
Toshiba EQP Global 841 Motors are designed for severe duty applications in the chemical, mining, mill, oil and gas industries. The Class I Division 2 and vacuum pressure impregnated (VPI) Class F insulation provides additional reliability to withstand harsh environments. The IP56 protection includes non-contacting labyrinth seals on the DE and ODE to provide increased moisture and dust protection. According to the IEEE 841 standard, severe duty motors should be able to perform at ambient temperatures from -13 degrees F to 104 degrees F and altitude up to 3281 feet. They should have full voltage starting and tolerate humid, corrosive or salty environments. They are typically made of cast iron with a ruggedized frame to resist vibration, and painted with corrosive resistant paint.
Baldor-Reliance 841XL Motors are designed to meet and exceed the requirements of IEEE 841. This Industry standard was created for the Petroleum and Chemical industry to improve the reliability, efficiency and performance of Severe Duty motors used in those applications. Other severe process industries like Forest Products have also adopted using the IEEE 841 spec as it helps promote uniform motor specification and reduce total cost of ownership.
