Cliff,

Just out of curiosity, has anyone ever played around with superimposing DC onto the AC which supplies the field windings of the AC motor. It is my recolection that if you place DC onto the windings of an AC motor it will act like a magnetic brake. Perhaps, the speed could be controlled by varying a DC component in the field coils of the AC motor. Just a thought, I have no idea if it is even a viable idea.
