The only problem there is, if you stop the arbour too quickly the
arbour nut will wind off as the blade trys to keep spinning.
Same thing happens if DC injection on ann AC motor or
resistive(regenerative) braking on a DC motor is too harsh..


Neither of us is trying to stop the blade that fast.


That's why the "saw stop" HAS to stop the blade directly. Stopping the
blade that fast through the arbour would inevitably wind the blade off
the arbour before the blade came to a safe stop.

I seriously doubt that was even the slightest consideration for the
inventor of the SawStop.
From what I was told it WAS.
