Electro-Optical/Infrared systems require smooth, responsive motion perfectly coordinated between azimuth and elevation axes. To acquire and hold a steady image, motion systems must endure and counteract forces such as the pounding of land vehicles in action, the turbulence of aircraft in flight, and the extreme conditions encountered at sea or even in space.

The most ambitious motion design. The most capable engineering. The most confident delivery. With more than 70 years of proven aerospace and defense experience, Kollmorgen is the motion partner you can trust for any EO/IR mission.

Knowledge on Demand

Learn about the latest technologies and best practices to deliver stable motion platforms for EO/IR applications with our new on-demand educational series Focus on Frameless: Creating Stable Motion Platforms for EO/IR.

The series covers four main considerations and requirements for selecting a motor for EO/IR platforms: choosing the proper motor size, optimizing form factor, addressing cogging and torque ripple, and understanding motor topology. From looking at how environment impacts motor selection to understanding conventional versus slotless motor design, each video examines the technologies, challenges and options related to motor selection and optimization for EO/IR platforms.


Motion to Meet the Mission

Electro-optical/infrared systems play a crucial defense role on land, in the air, at sea and in space. Each type of system has features in common, yet each operating environment brings its own unique challenges. See how we engineer motion solutions to help you make every design mission a successful one.

Blog in Motion

In our latest blog series, we cover the technologies, challenges and best practices around motor design and performance for EO/IR platforms. From understanding the performance differences between conventional and slotless motors to learning how cogging torque and torque ripple affect performance, we delve into the topics that are necessary to understand when building or upgrading a motion system.

Cogging Torque and Torque Ripple

Cogging Torque and Torque Ripple: What You Need to Know

Cogging torque and torque ripple are mechanical and electromechanical forces that can potentially impact a motor's performance. Learn what these two forces are, what their true role is in a motor’s performance and how to address them for a stable motion platform.

Brushed or Brushless

Brushed or Brushless: Choosing the Right Motor for the Application

Brushless motors dominate the EO/IR landscape, but brushed motors still have value, especially in certain applications. In this blog, we cover the basic design differences between brushed and brushless motors and look into the applications and situations where brushed motors might have an advantage and when it might be time to upgrade.
