The ability to respond quickly to radar tracking images depends on real-time accuracy and high image resolution. And the accuracy and resolution of these images depends on the size of the antenna and the ability to position it with continuous and unfailing precision. For decades, Kollmorgen motion solutions have been proven performers in the most critical positioning tasks and harshest battlefront conditions.

Torque and Precise Control for Land-Based Systems

The motors used to position radar and satellite antennas must provide the torque needed to accelerate and decelerate the substantial mass of the antenna quickly and to hold position accurately. The entire system depends on servo motors that can respond instantly and precisely while operating continuously in all conditions.

Compact, Efficient Direct Drive Motors for Vehicles and Ships

For pedestals mounted on a ship or vehicle, the motion requirements are even more extreme. Positioning adjustments must be made constantly in response to ever-changing input from the control systems. The need for quick, precise, infinitely adjustable motion—combined with the need to accommodate very tight space and weight claims—means that direct-drive servo motors are the preferred choice. In particular, frameless motors enable the tightest integration within the confines of the pedestal design.

Reliable Solutions From a Supplier You Can Count On

Above all else, motion components for defense applications must operate with total reliability, even as they’re exposed to extremes of weather, corrosive conditions, vibration and shock. Kollmorgen supplies standard motors that deliver all the required torque, speed and precision, along with corrosion-free finishes, impervious seals and rugged construction to survive almost anything. We can also build completely custom components to the same environmental specifications—and deliver them in the quantities and on the schedule that military operations require, anywhere in the world.
