    Engineered for excellence


    Fairbanks Morse Defense and Ward Leonard MIL-Spec motors are designed to meet MIL-M-17059 and MIL-DTL-17060 specifications and are manufactured to endure exposure to combat, rigorous shock, and saltwater for decades of use. Constructed with nodular cast iron, these rugged motors feature a vacuum pressure impregnation (VPI) epoxy-sealed insulation system, MIL-STD-2037, that delivers superior electrical insulation and water resistance.

    Ward Leonard motors also meet Grade-A shock, MIL-DTL-901, and vibration performance standards, MIL-STD-167, that are frequently required in Naval motor applications. Our motors are NAVSEA-approved in painting and welding, and meet the NAVSEA-spec for corrosion resistance. Our motors are designed to have service lives of 30 years and have been proven with performance in the U.S. Navy fleet to exceed this standard consistently.
