How Do Electromagnetic Brakes Work?


Electromechanical brakes operate through an electric actuation, but transmit torque mechanically. When voltage or current is applied, the coil is energized thus creating a magnetic field. This then turns the coil to an electromagnet which develops magnetic lines of flux. This flux attracts the armature to the face of the brake. The armature and hub are normally mounted on the shaft that is rotating. Since the brake coil is mounted solidly, the brake armature, hub and shaft come to a halt in a short amount of time. When current or voltage is removed from the brake, the armature is free to turn with the shaft. In most designs, springs are the ones that hold the armature away from the brake surface when power is released, thus creating a small air gap. Cycling is achieved by turning on and off the voltage or current to the coil. Slippage should occur only during deceleration and when the brake is engaged, there should be no slippage once the brake comes to a full halt.

They basically work by energizing a coil that clamps a grip around the motor shaft. Some typical ones take about 24V in to release. Here is a company that makes brakes.
Electromagnetic friction brakes and clutches are the most common type of electromechanical devices. The applications for friction brakes and clutches includes packaging machinery,
elecromagnetic brakes well the best use is in bulle trains and speed record cars!!!!!cars travelling at 500-700 kmph need to stop a a much faster and more efficient way!!!!!!!his
