Product Description:
Eddy Current Dampers for Precision Motion Control in Critical Applications
CDA Intercorp designs and manufactures high-performance eddy current dampers that provide smooth, reliable, and precise motion control for aerospace, defense, and space applications. Built on our proven gearmotor heritage, these dampers utilize advanced materials and manufacturing processes to deliver consistent damping performance in demanding environments.
Our eddy current dampers are available as passive systems that require no external power or as active configurations with adjustable damping rates for applications requiring greater control. This flexibility makes them ideal for deployment mechanisms, antenna systems, spacecraft components, aircraft assemblies, and other precision motion control applications where controlled movement is essential.
CDA also offers COTS dampers (Commercial Off-The-Shelf dampers) for customers seeking proven, ready-to-integrate solutions with reduced development time. For applications requiring minimal resistance during deployment, we provide cogless configurations that significantly reduce drag torque while maintaining reliable damping performance. These designs are particularly beneficial in spaceflight systems where maximizing deployment margin is critical.
With decades of engineering expertise, CDA develops custom eddy current damping solutions tailored to specific torque, size, environmental, and performance requirements. Our products are trusted in mission-critical applications where reliability, precision, and long-term durability are essential.

When it has to work
We support missions where components must work every time, because if they don’t, the mission may fail and lives may be lost. That’s critical engineering at work. That’s fifty years of space, downhole oil & gas, and defense heritage. That’s CDA InterCorp.
