  2. Eddy current brake - Wikipedia

    en.wikipedia.org/wiki/Eddy_current_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 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 ...

  4. Eddy current - Wikipedia

    en.wikipedia.org/wiki/Eddy_current

    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 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.

  6. Electromagnetic brake - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_brake

    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.

  7. Electromagnetic clutches and brakes - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_clutches...

    The fields of EM couplings can be made to operate at almost any DC voltage, and the torque produced by the clutch or brake will be the same, as long as the correct operating voltage and current is used with the correct coupling. If a 90 V clutch, a 48 V clutch and a 24 V clutch, all being powered with their respective voltages and current, all ...

  9. Railway brake - Wikipedia

    en.wikipedia.org/wiki/Railway_brake

    Air brakes at the outermost vehicles of a train are turned off using a tap. Vacuum brakes at the outermost vehicles of a train are sealed by fixed plugs ("dummies") onto which the open end of the vacuum pipe is placed. It is sealed against a rubber washer by the vacuum, with a pin to hold the pipe in place when the vacuum drops during braking.
