Controllable Drive Actuators: Eddy Current Dampers

Linear Eddy Current DamperCDA InterCorp’s Rotary and Linear Eddy Current Dampers offer reliable, repeatable, and linear damping characteristics over a wide operating temperature range. These rugged devices are offered in a range of sizes and damping rates.

The Eddy Current Dampers (ECD’s) are complemented with single or multiple stages of high reliability gearing. Ideal for demanding applications, these devices will operate reliably at high angular rates, accelerations and radial loads.

Technical Data
Diameter 0,5 to 3 inch [12,70 to 76,20 mm]
Length depending on windig, redundancy and feedback requirements
Damping rate up to 500.000 lb-In-sec/rad [56.000 Nm-sec/rad]
Gear ratio 4:1 to 6000:1
Input torque 18 to 3.000 lb-In [2 to 340 Nm], depending on gearing and ratios
