Ward Leonard has been partnering with the Military for over 120 continuous years, and our mission-critical products have been installed on virtually every surface and subsurface vessel in the U.S. Navy.
Ward Leonard Mil-Spec AC motors — including the Low Noise/Noise Quiet and Submersible Duty motors from 1/16 – 350HP — are designed and manufactured to adhere to NAVSEA’s stringent Mil-M-17060/17059 standards. Our ability to withstand Grade A shock requirements are met with the use of ductile iron motor construction and Ward Leonard’s proven experience in designing a complex piece of machinery to withstand lightweight, medium weight, and heavy weight shock testing.
Our sealed insulation system complies with the requirements of Mil-STD-2037 to enable our motors to withstand water submersion for extended periods of time. The use of precision components and exacting machining practices make possible our very low airborne and structure-borne noise level performance that are of extreme value in naval vessel applications. 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.
Ward Leonard also designs and manufactures commutator-type DC motors per Mil-M-17413A that are primarily used on U.S. Navy surface combatants and submarines. These applications demand rugged construction along with low noise performance characteristics to ensure the effectiveness of our naval forces in combat situations. These DC motors complement our full line of rotating equipment solutions for DoD applications that include fractional and integral horsepower AC induction motors and motor-generator sets for frequency conversion.
Ward Leonard motors are used by a wide range of US and International Defense organizations, including the US Navy, US Army, US Coast Guard, Military Sealift Command, Canadian Department of National Defence, UK Ministry of Defence, Australian Ministry of Defence.
