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
