Hello everyone,
I happen to have a spare PIC16F73 on my hands, as well as an AC PSC (permanent split capacitor) motor that needs variable speed.

What's the easiest way to electronically control the speed of a PSC motor? The input would be a simple variable resistor or rheostat.

What would be the way to go about this? I have no idea where to start.

(By the way, this forum rocks! There's such a wealth of information in the info pages, I could be reading for hours.)

I had that exact same window open, and was thinking of posting the link. I still don't really know how to approach the circuitry aspect though.
Is there a way to do this without a microcontroller, by the way?

What MOSFETS, etc. would I use?
