Gary,
What you want is a Salient Pole Synchronous motor. A motor that not only
snycs to the line frequency but does so in such as way that a given armature
position (relative to the stator) equals a given point on the AC waveform.
One can modify a sync motor to become a salient pole sync motor by milling
flats in the armature. Details of this process can be found in Brent
Turner's
book (bturner@apc.net) or by asking around in this forum (I've never done
it,
I purchased my Slaient Pole syncro from Brent).
