Dynamic braking - Wikipedia

Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotiveIt is termed "rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and "regenerative" if the power is returned to the supply lineDynamic braking reduces wear on friction-based braking components, and ,
