Computerized timer? Was RE: async rotory gap?

I wonder if it is feasable to have a computerized speed control, that would
use a  LED, and FiberOptics to sense if the rotor speed is falling behind,
it would increase voltage and if it is advancing too far it would lower the
voltage.

Lots of robotics are programmed in forth, and I could do that. Maybe it
would be a sync finder, where on startup, it would gradually increase
voltage till it gets into sync, and keeps it there.

snip!

 The other would be a DC motor. The DC motor has
the ability to run atvariable speeds as a function
of input voltage. With DC, you get to play
around with the break rates

The variable DC motor is really fun. You can speed up the motor vary the
break rate. Although you can near the AC charging cycle, you cannot lock
onto it.

Big snip!
