Dynamic braking is shorting the armature so the armature tries to lock.
Regenerative braking tries to recover the generated volts. I have never
seen the two terms confused till this thread. Slot cars used dynamic
braking in '67 and no one was confused over how it worked. We are
talking about technical terms. Lets use accurate wording.
Dynamic braking, as a 'term', just implies adding load so that the
voltages being generated by the motor, provide braking force. The load can
be direct shorting, resistive, or feeding into a circuit to do work. If
the 'work' is recharging the batteries, then it becomes 'regenerative'.
You will find that some vehicles like fork lift trucks,have 'regenerative
dynamic braking' units fitted. There is no confusion, _except_ in thinking
that 'dynamic braking', automatically implies the power is wasted.
Regenerative braking, is the 'descendant' of traditional dynamic braking
solutions, in putting the power to constructive use.

Best Wishes
