Time for a reality check.

Take your choice, dynamic or regenerative braking will never cut it as
a safety braking system.

Toss in disk brakes if that will make you happy.

All are much too slow to respond quickly enough to compete as a safety
device against SawStop.

As far as a braking system to bring a saw blade to a stop more
quickly, the economics will kill the idea.

The cost of a DC power supply, adjustable timer and a horsepower
rated, mechanically interlocked, set of contactors for a dynamic
braking system will be equal to or exceed the cost of a motor which
will also require added stator pegging to keep it from being ripped
loose from the motor housing.

Similar cost structures are4 in play for the other options.

Back to the drawing board.

Waiting for a T/S blade to stop spinning is a good time to collect
your thoughts.

When working around woodworking tools, patience is a virtue, IMHO.
