Therefore, the steady-state voltage will be 1.8 * 2 = 3.6 V

You'll be using Gecko or some similar driver? You should use a power supply
of 75 V or more, as these motors may have fairly high inductance. 1.8 A
x 2 (phases)
* 3 (axes) * .67 = 7.2 A, but this is a peak rating when all 3 motors
are accelerating
at near maximum speed. A power supply with 5 A continuous rating would do
fine.
