Ground and Naval Defense

Ground and Naval Defense

Military systems depend on absolute accuracy, power and robust capabilities in confined spaces and harsh environments. Exlar® linear actuators and brushless servo motors bring maximum force and robust performance in small packages. Our proven solutions are accurate, efficient and battle ready.

ELECTRIC ACTUATION FOR MISSION CRITICAL APPLICATIONS

Hydraulic actuators, commonly known as “cylinders,” have been used on ground and naval defense platforms for decades. Hydraulic cylinders have very high force to size ratios, making them very popular on military vehicles. Although once ground and naval defense platform designers began to recognize the benefits of using all electronics on some vehicles and programs, linear EMAs were quickly seen as a direct replacement to hydraulics. As an industry recognized hydraulic replacement, we manufacture COTS and mCOTS linear and rotary actuators that cover a wide range of motion applications for the defense industry.

While linear EMAs can directly drop into hydraulic systems, many linear systems can be converted to rotary EMAs for additional benefits. High-torque rotary actuators are an excellent replacement in the actuation of many hinged components such as:

  • Ramps
  • Doors
  • Hatches
  • Radar deployment
  • Gun elevation
  • Missile launch elevation

Not all Actuators are Created Equal: the Roller Screw Technology Difference

Utilizing roller screw technology and integrated brushless servo motors, Exlar actuators offer clean, fast and accurate control over a wide range of force, speed, and positioning. With continuous force ratings in excess of 40,000 pounds (177,929 N) and linear speeds exceeding 60 inches per second (1.5 m/sec), our actuators are built to last and guarantee reliable results.

Our technologies meet the military’s growing need for rugged, reliable, electrically powered systems. Our compact actuators and motors are:

  • Specified on weapons systems for vehicles in the Future Combat System
  • Part of the design for the Navy’s Advanced Gun System
  • Used for valve control on Navy ship systems

Advantages of Electromechanical Actuation in Defense Vehicles

Military vehicle designers are constantly searching for measurable and impactful changes in their systems designs. Designers need technology that can meet the new demands for efficiency, increased power and improved size and weight. To accomplish these goals, designers are incorporating actuation systems into the vehicles. Initially, many of these designs utilized hydraulic actuation but, lately, there is an increased use of electronic systems because of their greater efficiencies, leading to lower power consumption and maintenance costs. Moreover, the simplified designs also lend themselves to increased survivability.
