electric braking achieved by switching the power supplied to the windings of an actuating motor in such a way that the direction of the tractive force is reversed. This reversal can be obtained either by changing the polarity of the voltage connected to the winding of the rotating armature of the motor or by switching two phases of the stator winding. The magnitude of the braking torque can be regulated by adjusting a resistance in the armature circuit. When reverse-current braking is applied, the power feed must be immediately disconnected from the power supply network after every shutoff of the electric drive in order to prevent the actuating motor from reversing its motion. Reverse-current braking is used in the electric drives of hoisting and conveying machines, rolling mills, and roller conveyors.
