I understand now, I hope. Why is it that servos don't also need the high
voltage? As the frequency of the steps going out to the stepper increases
what happens to the voltage needed to supply to correct current? Does it get
higher because the higher frequency passes through the coils worse? I'm only
remember that with N2 lasers the laser uses a wire to connect two plates of
a capacitor together so they can charge and start the gas lasing in the
cavity. But then when the spark gap breaks down the frequency rockets and
the wire connecting the plates becomes 'invisible'. Am I talking nonsense?
