Abstract

An eddy current brake, like a conventional friction brake, is responsible for slowing an object, such as a
train or a roller coaster. However, unlike electro-mechanical brakes, which apply mechanical pressure on two separate
objects, eddy current brakes slow an object by creating eddy currents through electromagnetic induction which create
resistance, and in turn either heat or electricity. When the primary magnetic field and the secondary conductor of the
eddy current brakes has relative motion ,the eddy currents will appear in the conductor and the braking force will be
produced by the interaction of the eddy currents and the primary magnetic field. Due to the internal resistance of the
conductor, the eddy current will dissipate into heat and the force will vanish. The force is dependent on the velocity of
the change in magnetic flux and resists the change in flux. The brakes based on this principle have been found in many
applications. For example, vibration suppression, vehicle suspension systems, high speed train braking systems,
transmission systems, haptic interfaces, space docking mechanisms, loading systems and so on.
