Review Paper on Eddy Current and Electromagnetic Brake

Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off. A disk eddy current brake consists of a conductive non-ferromagnetic metal disc (rotor) attached to the axle of the vehicle's wheel, with an electromagnet … Visa mer An eddy current brake, also known as an induction brake, electric brake or electric retarder, is a device used to slow or stop a moving object by generating eddy currents and thus dissipating its kinetic energy as heat. Unlike Visa mer Most chassis dynamometers and many engine dynos use an eddy-current brake as a means of providing an electrically adjustable load on the engine. They are often referred to as an "absorber" in such applications. Inexpensive air … Visa mer In physics education a simple experiment is sometimes used to illustrate eddy currents and the principle behind magnetic braking. When a strong magnet is dropped down a vertical, non-ferrous, conducting pipe, eddy currents are induced in the pipe, and these retard the descent of … Visa mer An eddy current brake consists of a conductive piece of metal, either a straight bar or a disk, which moves through the magnetic field of a magnet, either a permanent magnet or … Visa mer Linear eddy current brakes are used on some rail vehicles, such as trains.

I.e. braking force depends not only on the magnetic field but also on the speed of the conductor moved through the field. They don't brake at all if everything is at rest; no matter how strong the field is (that's why they often are ideal for dampening).
