Help with wire sizing

I want to use CAT 5 network cable for wiring small stepper motors
(1.5 amp/phase or smaller) I am talking from the driver to the motor.
The cable is sheathed with 4 twisted pairs (I believe). Is there a
problem with doing this? The individual conductors are solid copper,
appx .020" which I believe to be 24 AWG. I did the current density
numbers and came up with about 4.8 amp/mm2 . The SAE handbook says
anything below 30 amp/mm2 is good for intermittent automotive
applications.
Any input on this? Is this OK
