Upon second thought, I think you are actually right that you should reduce
the current, as unipolar "center-tapped" motors are designed/wound with the
expectation that only half the winding will be conducting at any given time.
Thus, the dissipation would be DOUBLE if you fed "rated current" (1.0 amp)
through both sides, all the time. I never dealt with this consideration,
therefore I stumbled. Duh...
