Modifying a Shaded Pole Motor
Eric,
I took a look at your pictures.
You are totally on the right track here!!!! Cutting the stator core laminations is a bit tricky because they are covered with Silicon (glass) insulation. It tends to dull your cutting tools pretty fast.
Also, you'll find that running the coil on 12 volts DC will give you a lot of power, since there is no Back EMF in the coil to buck the input. You won't be able to run it on 120 volts DC as you suggested. It will melt the coil.
Make a new rotor that is just a bar (with curved ends) of cast iron across the section of the stator that is left after you cut away the sections you have marked.
Set the commutator to turn the coil ON when the front edge of the rotor is at the front edge of the stator, and to turn the coil OFF when the rotor is half way into alignment. The collapsing field will keep motoring the rotor forward until the magnetic field disappears, at which point the rotor will slide out of alignment unopposed.
This is the simplest version of the idea. This will work better than the "S" rotor and is the basic method we used in 1983 with the original Flux Motor, as far as just attracting bars of iron to the stator sections.
Keep us appraised of your progress! You really do understand the idea. Way to go!!
