[CAD_CAM_EDM_DRO] Choosing Power/Volts on Stepper Motor

How do you choose the right supply voltage to run my Stepper Motors at?

If I figure how much power I need by multiply the IPM by in-oz (motor
Specs) and then dividing the result by 531. My results will be in Watts
of power. So how do I take this result in Watts and figure out what
voltage I should be running my Stepper Motors at?


Motor Example:

4 Wire Bipolar Stepper
2.3 Volt/Phase
80 oz.-in.
1.5 Amp/Phase DC,
1.5 Ohm/Phase,
Steps 200,
Size NEMA 23

Motors to be used on Table Top CNC with 200 IPM max.

The reason I ask is I want to decide which driver to go with to run 3
axis. One axis needs to have two motors used it.
