Re: need small AC motor speed control circuit
We started with DC fan and motor. Unfortunately we were not able to get the flow characteristics needed (i.e. sufficient flow at a high pressure) with the DC motor and fan. Therefore we had to go to the radial curved centrifugal fan which has an AC motor. I've seen AC speed controllers which use a t...

need small AC motor speed control circuit
I'm attempting to use a PWM or a 0-5V signal from a microcontroller to control the speed of a small (0.17amp) AC fan motor. Does anyone have a circuit diagram which can do this? I'm considering using a TRIAC.
