Founded in 1898 by two of George Westinghouse’s engineers, Pittsburgh’s Stimple & Ward Company manufactures electric motor and control coils for industrial, power-generation, repair, and transportation equipment. America’s oldest independent electric motor coil manufacturer, it draws on more than a century of winding data, patterns, and tooling—much of it developed through longstanding service to U.S. Steel mills—to make both replacement coils and custom designs. Its 20,000-square-foot Pittsburgh plant is complemented by a 15,000-square-foot facility in Cranberry Township for magnet-wire manufacturing and distribution.
