I got the desire for a FAST rise time, but the current is limited.
therefore the voltage seems like it should be much less than the
power supply. V=I*R would seem to use a fixed resistance in the
motor, and a limit on the current?

average voltage and average current would be back at nameplate ?

Maybe I'm missing something about the inductance?
