Eddy Current Brakes

HOME / Applications / Actuators, Solenoids & Electromechanical / Eddy Current Brakes

Eddy current brakes are based on the braking torques (forces) generated by induced Eddy Currents inside an electrical conductor by electromagnetic induction. Stationary electric conductor immerged inside a time-varying magnetic flux and/ or a moving electrical conductor inside a static magnetic flux will lead to the creation of eddy currents in this conductor.

In this article, rotary eddy currents brakes (ECB) will be studied. Typical braking systems (hydraulic, pneumatic, mechanic) employed in most engines, are designed to slow or halt the motion of vehicle by converting kinematic energy to heat energy by friction.
