When your severe duty applications need severe duty performance, the innovative cast-iron, totally enclosed fan cooled (TEFC) World Motor® line products stand up to the harshest environmental conditions. Comprised of HOSTILE DUTY®, CORRO-DUTY®, 841 PLUS® and INVERTER DUTY™ products, the World Motor horizontal motors line provides you a robust family of U.S. MOTORS® brand products featuring world-class design and exceptional quality.

These products are built to withstand a variety of severe duty applications in oil and gas, pulp and paper, mining, saw mills, foundries, chemical plants, waste management and other process-related industries. If you are looking for versatility and global functionality, World Motor products meet or exceed either National Electrical Manufacturers Association (NEMA®) or International Electrotechnical Commission (IEC) standards. This helps your company save money thanks to increased energy efficiency over other products.

  • Easier Connection. World Motor is built with a larger conduit box for easier connection.  Improved conduit box sealing provides better environmental protection.
  • Versatility. Multiple conduit box locations and connection options are available for an easier fit into any installation.
  • True cast iron 140 frame size. Full cast iron construction is more robust than the standard rolled steel. World Motor provides sturdy reliability in severe duty applications.
  • Perfect replacement motor. Dual drilled feet make replacing older installations – that may have accommodated smaller or larger motors – easier. There’s no need to change the mounting pad or foundations.
  • Longer fins for better cooling. The motor runs at a lower temperature thereby increasing the life of the winding insulation. A cooler running motor delivers higher efficiency.
