I’m not aware of any brake on a TS, but I’m no expert. My experience is the motor and blade take quite a long time to come to a stop.

I can spin the blade off my TS when powering down if I want (which I don t!)... I just set the deacceleration time to a couple of seconds or less :)

AFAIK, that griz just has a pretty standard TEFC motor and there is no mechanical brake involved… although a lot of people hear the centrifugal switch closing down and mistake that noise as a brake. Depending on age, it may be slowing down faster than normal due to bearings, but they would have to be pretty bad to effect it enough to spin the blade off.

Never heard of mechanical brakes on induction motors although I asuume there are some somewhere. The common and cheap way to brake induction motor is by induction not friction.
