DC Motors

A History of Firsts
Our presence as a world leader in the engineering and production of DC motors is built upon a distinguished record of pioneering achievement in the steel and mining industries.

Working with the steel industry, Westinghouse developed and installed the:
  • First electric motors in an American steel mill (1891)
  • First electric drive for main rolls
  • First reversing mill drive
  • First large twin-motor reversing mill drive

Some of our significant achievements in the mining industry
include the:

  • First application of separately excited shunt-wound DC motors
  • First Ward Leonard dragline systems
  • First vertical swing motors
  • First laminated frame generators
  • First dual circuit generator system

Perpetuating a proud tradition, TECO-Westinghouse has continued through the years to refine our DC motor product lines with quality enhancing features that secure our position of leadership within the marketplace.

Among the many Westinghouse "firsts" in the history of DC motors was the nation's first reversing rolling mill motor (pictured above), which was installed in 1905.
