English: A diagram showing how a disk-type eddy current brake works. Eddy current brakes are used in power tools like circular saws to stop the blade quickly, and in electric meters. The brake consists of a spinning conductive metal disk (D) spinning counterclockwise in this example, whose surface is positioned between the poles of a magnet (N ...
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 attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...
English: Diagram of eddy currents (I, red) induced in conductive metal sheet (C) moving under a stationary magnet (N), showing the origin of the braking force The magnetic field lines (B, green) from the North pole of the magnet extend down through the sheet.
Eddy current brakes use the drag force created by eddy currents as a brake to slow or stop moving objects. Since there is no contact with a brake shoe or drum, there is no mechanical wear. However, an eddy current brake cannot provide a "holding" torque and so may be used in combination with mechanical brakes, for example, on overhead cranes.
English: Diagram showing the forces on an electron in a metal sheet moving to the right under a magnet , explaining eddy currents, and where the drag force on the sheet comes from.
Related types of such a brake are eddy current brakes, and electro-mechanical brakes (which actually are magnetically driven friction brakes, but nowadays are often just called "electromagnetic brakes" as well). Electromagnetic brakes slow an object through electromagnetic induction, which creates resistance and in turn either heat or ...
