Just a forewarning, I'm completely new to circuits so some of my questions may sound pretty dumb. Anyway, here's my situation, I've got an 120VAC, 3.8W, 36RPM motor that I want to control the speed of. I thought I could wire in a dimmer switch and that would work, but I was wrong. The motor only turns when the dimmer switch is all the way on and only at full speed. Anybody have any ideas on how I can slow the motor down? Thanks in advance.

How can I tell what kind it is? I don't have any documentation other than the sticker on the back.

To change the speed of synchronous motor you need an inverter to vary the supply frequency. Speed of synchronous motors depends on the supply frequency.
