Severe Duty Motors

Extreme-duty IEEE 841 motors are intended for use in petrochemical, pulp, paper, and steel processing applications in dusty, unclean, nonhazardous settings. For moisture protection, they have sealed ball bearings, breathers/drains, gasketed conduit boxes, and shaft seals. Motors have a stainless steel nameplate and a coating that resists corrosion. They are three-phase and do not require centrifugal starting switches, which can wear out and malfunction, or starting capacitors or run capacitors. To blow cooling air over the motor, models with a fully enclosed fan-cooled (TEFC) enclosure have an exterior, nonsparking fan covered in a protective shroud.
