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: 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 ...
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.
Electric brake is an ambiguous term meaning more than one thing: Dynamic braking, Braking using magnetic currents either to charge a battery or waste as heat; Electric friction brake, Electrically controlled friction brake; Track brake; Regenerative brake; Eddy current brake, Braking using eddy currents

Electromagnetic brakes or EM brakes are used to slow or stop vehicles using electromagnetic force to apply mechanical resistance (friction). They were originally called electro-mechanical brakes but over the years the name changed to "electromagnetic brakes", referring to their actuation method which is generally unrelated to modern electro-mechanical brakes.
Language links are at the top of the page across from the title.
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 ...
