Christopher,

I don't trust the dead pole method.  I just make the flats a certain
proportional width of the armature diameter.  I've modified all types
of inductions motors and they all work well for sync-mod'ing.
I think Bill's methods are mostly applicable to larger (2HP or larger)
motors.  The only type of induction motor that is not very good is the shaded
pole type which are generally small and really cheaply made.  I'm
assuming your motor is at least an induction motor.

The type of induction motor mostly affects the amount of weight
of the rotor that can be handled.  Cap-start motors have a lot of
starting torque.  Cap run are stronger than induction start/run, etc.
Shade pole motors are wimpy.
