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 ...
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.
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 ...
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.
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 and S). The magnetic field (B, green) passing downward through the disk, induces circular electric currents (I, red) , called eddy currents in the metal of the disk.
A hybrid vehicle drivetrain uses electrical retardation to assist the mechanical brakes, while recycling the energy. The electric traction motor acts as a generator to charge the battery. The power stored in the battery is available to help the vehicle accelerate. Regenerative braking and eddy current braking are separate types of electric ...
