A shot of DC into an AC motor will stop the motor. Plan is to open one of the 240 V AC lines and insert a NC, SW in parallel with a diode. Opening the SW will send the DC shot to the motor; the regular motor SW is shut off at the same time. What should the PIV and A ratings of the two diodes be?
1) max draw 8A, operating draw 3-4 A (table saw)
2) " " 5A " " 2-3 A (radial arm saw)
How long would it take (us or several sec.) for the varnish on the windings to melt? or would that even be a problem?
I'm aware of the inertial hazard of the blade coming off - turn the saw back on quickly.
