Well, if you need 2000 RPM from this motor, you will have to have a power
supply of 50 V plus a bit for the armature resistance.

If you need 500 Oz-In of torque, you'd need 500/33.775 = 14.8 Amps.

What linear force do you need to apply to the machine table? What maximum
rapid traverse rate dou you need? What is the leadscrew type and pitch?
