Definition of "braking" |
operating condition in an electric motor in which the torque developed between the stator and rotor coils opposes the direction of rotation of the rotor. Typical braking methods in DC machines include “plugging” in which the polarity of either the field or the armature coil, but not both, is reversed while the rotor is turning, “dynamic braking” in which generator action in the armature is used to dissipate rotor energy through a braking resistor, and “regenerative braking” in which generator action in the rotor is used to dissipate rotor energy by returning electric power to the power source as the rotor slows. Typical braking methods in AC machines include switching of the phase sequence of the supply voltage, dynamic braking through the armature coils, and varying the frequency of the AC supply voltage. |
