AC Induction Motor

This is a permanent split-phase AC induction motor (i.e. capacitor start/run) that I made for my graduate mechatronics class at UT. The windings are wrapped with ~220 turns of 32 AWG magnet wire. Power is from a 20 V transformer (@ 60 Hz, of course). The phase shift for the auxiliary windings is from a 220 uF capacitor. Total current draw is a touch under 2A, more than the transformer is really rated for, so I can't run it for too long. The rotor is the steel jar lid. The bearing is simply a pencil, as graphite makes a fantastic mechanical lubricant. Here's a schematic similar to what I built: http://www.allaboutcircuits.com/vol_6... Differences: I was using a 220 uF capacitor, so impedance was only 12 Ohm. IF using a smaller cap, you want a comparable resistor (high voltage rating) in front of the other winding (this diagram uses a lightbulb for a resistor). Also, I had pole pairs rather than single poles, so each pole in that schematic is split into two parallel poles in my design. Hope that helps!
