First you look at the torque required, then the RPM. Then I also looked at the drive specs you provided. So that, plus my general refitting experience led me to those motor sizes. In general, a 0.75kW servo will be in the range for axis drives on a Bridgeport type machine. A larger bed mill may be more happy with a 1kW X/Y axis drive, and with the higher mass of the Z axis, normally you would want to step up to a larger motor. Also, you may want the Z axis motor equipped with a brake, for power off position holding, depends it the Z axis is counter weighted or not.
