Reply to "Motor Voltage???"

Bob,

I hope one of the experts jump in. Per all the forum discussion on chopped and rms (root mean square) sine waves, the numbers you mention are "effective" values. An estimate for the peak of the ac wave would be for example (square root of two)*18 volts. This would not be an effective value, but would be the highest voltage on the wave, which is what I think you are looking for. 120v house voltage is the effective value, the peak of the sine wave is 120*1.414 or around 170v.

I will look for one of those other threads, they had scope pictures, I think GRJ did several of them.
