Braking and Regenerative Energy with AC Drives
What is Regenerative Energy? When a motor turns faster than the commanded speed as set by its AC variable speed drive, the motor in effect acts as a generator. An example of this would be the control of an elevator car as it descends. With the help of gravity, the load will readily lower. In fact

Regeneration vs. Dynamic Braking in DC Drives
Both regeneration and dynamic braking (DB) slow down a rotating DC motor and its load, but when should one method be chosen over another, or when possibly should both be used? There are significant differences in stopping time, controllability during stopping, and safety issues depending how one
