I'll answer it here

Rather than starting a new thread, I'll answer what I can here.

The problem is not the processing required to make the waveshape, it's that the waveshape required continually changes. This arises because of the variable phase relationship between the rotating electrical field and the rotor itself: although a synchronous motor is frequency locked it isn't phase locked and the rotor lags the field by an amount that varies with torque demand.

Measuring this is not trivial.
