Entertainment yes. Stopping the motor ? No!

His Sensei is behind the crowd with a kill switch.:lol:
There could be a high speed low power motor hidden in the inside of the motor housing. He could lighly hold the steel against it to make sparks but could fairly easily stop it with his hands.
Something is awry, no doubt. But it's interesting to see the "Asian Master" trope presented like this. The heraldic shield is also a nice touch.
Inside that big motor is a motor the size of the cooling fan in your old PC...
Dynamic braking? Short the motor's wires together and it'll stop quick. I was watching his toes to see if he pressed a switch.Quote:
