FAQ: What is dynamic braking and when is it used?

Dynamic braking is used when energy needs to be dissipated periodically, and regeneration is generally preferred when the motor is frequently acting as a generator. From an application standpoint, overhauling loads (a condition where the load is moving faster than the designated motor speed), such as conveyors and cranes, cause energy to be ...

Regenerative brake - Wikipedia

Regenerative braking has a similar energy equation to the equation for the mechanical flywheel. Regenerative braking is a two-step process involving the motor/generator and the battery. The initial kinetic energy is transformed into electrical energy by the generator and is then converted into chemical energy by the battery.
