Dynamic Braking

What causes the car to continue to roll when the power is shut off is that the motor becomes a generator, and tries to run itself, this is called Electromotive Force (emf) a term used to characterise electrical devices, such an electric motor, if an electric charge passes through that device, and gains energy.

Dynamic braking, is a short across the leads to the motor. The rolling cars wheels turn the motor armature, the motor will then, in affect act as generator. For a given direction of travel, current flow through the motor armatures during braking will be opposite to that during motoring. Therefore, the motor exerts torque in a direction that is opposite from the rolling direction of the car. Braking effort is proportional to the product of the magnetic strength of the windings.
