shaded pole motor speed control
I may be asking to much. I'm looking for a simple circuit to control the speed of a couple small AC muffin fans. I've tried lamp dimmers, and they just don't work, they are very eratic and nonlinear.
I've done dozens of searches, and came up with only a few circuits, none of which really looked like they would do the job.
Is there such a thing as a simple (not to expensive) way to do this? I've considered using a 555 timer to create a sort of frequency drive, but I only know the basics. I'm not at all sure a square wave would be suitable to drive an AC motor.
Thanks for reading and I hope you can point me in the right direction.
