What Does Severe Duty Mean?

Sometimes referred to as ‘hostile duty motors’, severe duty motors are an unofficial class of rugged, industrial motors. The term may refer to any TEFC motor, but more commonly refers to IEEE 841 motors. They typically come with a cast iron construction to withstand harsh applications.

Severe duty motors are more likely to protect the motor from airborne contamination or mechanical stress. For added protection and longevity, these often come with sealed bearings, which limits potential overload situations. Bearing failure is the most common cause of motor failure.

These motors are constructed with especially durable materials. The fan cover will typically be cast iron, whereas some general-purpose motors will offer a plastic fan cover. The junction box will typically be cast iron as well, instead of aluminum or steel.

What is an IEEE 841 Motor Rated For?

IEEE 841 is the Cadillac of motors, offering superior construction and capability. These were first introduced in 1986 for use in petroleum and chemical industries. They’re meant for severe duty applications and offer an extended lifespan; despite the added stress and contamination they encounter.

Features include:

  • Insulation: They’re designed with a minimum of class F insulation. This means the insulation can withstand temperatures of 130° C.
  • Enclosure: These severe duty motors come Totally Enclosed Fan Cooled with Inpro seals in each end and are rated Class 1, Division 2
  • Oversized greaseable bearings
  • Epoxy paint with a stainless nameplate
  • Tropicalized winding to prevent fungus
  • Only come in three-phase 460V or 575V with 3-leads
  • Rotor is balanced to a higher tolerance to meet 0.08 in/s of vibration
  • Motors comes with a routine test report
  • Warranty: Because of their rugged design, these motors come with a standard 5-year warranty.
  • For additional specifications, check out our article and video on IEEE 841 motors.

Where to Buy IEEE 841 Severe Duty Motors in Canada

eMotors Direct’s stock of severe duty electric motors meet and exceed the IEEE 841 standard set out in 2009. This standard was created by the Institute of Electrical and Electronics Engineers to improve the efficiency, reliability, and performance of electric motors used in the petroleum and chemical industries. IEEE 841 motors have now been adopted as a standard in additional industries, like oil & gas, pulp & paper, wastewater treatment, and mining, due to their inverter duty and constant speed abilities. You’ll find these electric motors are most often applied to compressors, pumps, fans, conveyors, and gear reducers. Rated as NEMA Premium Efficient, these severe duty motors have additional protections that help to reduce downtime and overall cost of ownership.

Our IEEE 841 motor category covers three-phase, single speed electric motors. Select your motor from horsepower options of fractional to 500 HP and a variety of voltage input and RPM output ratings. Choose a motor with either a totally enclosed fan cooled (TEFC) or totally enclosed non-ventilated (TENV) enclosure and various mounting options. Shop from the best brands available in North America; TECO-Westinghouse, Nidec, Marathon, Leeson, and Baldor severe duty motors.
