However, when motor braking can be less precise, dynamic braking may be a less-costly solution. Dc motors are normally braked by disconnecting the armature from the power source.

GE has teamed up with the Barbarian Group on a beautiful video that illustrates the science of hybrid dynamic braking with falling tomatoes, Christmas ornaments, watermelons, marbles, and more.

GE’s dynamic braking system for trains works like that ballistic gel under the falling watermelons and bowling balls: it converts and stores some of the energy that’s usually lost as heat from ...

The program will include two automatic emergency braking systems — crash imminent braking and dynamic brake support — in recommendations to new car and truck buyers.
